2.2
DESCRIPTION AND OPERATION
ATC-Series cyclones are high-efficiency dust collectors designed to eliminate airborne dust as it is generated. Contaminants are captured at the source(s), and then conveyed through ductwork to the collector where the dust is separated from the air stream and collected. The primary mode of operation is the air cleaning operation. The separated dust is discharged into a collection container. The cleaned air is then exhausted into the atmosphere or further filtered through afterfilters.
2.3
AIR FILTERING OPERATION
Normal operation consists of the air filtering operation and the resulting cleaned air discharge.
During the air filtering operation, contaminated air is drawn into the Clean Air Industries Amtech ATC Cyclone Dust Collector through the air inlet located on the upper barrel above the internal helix (see Figure 1). The contaminated air spirals down and accelerates as the cone narrows whereby higher centrifugal forces are exerted on dust particles in the air stream. As the contaminated air travels down the cone, it accelerates and the particles are thrown to the periphery of the air stream. Aided by gravity, the heavy particles are discharged into a dust-tight container (i.e. drum or hopper). As the particles drop out, the exhaust air stream spirals upward inside the downward stream of contaminated air into the fan housing and is then exhausted into the atmosphere.
NOTE: For fine dust and dust with low densities, the cyclone should be considered only as a pre-cleaner. Secondary filtration may be required.

4. INSTALLATION 4.1 OFF LOADING AND INSPECTION
ATC-Series cyclone units are shipped with major components mounted on skids, size permitting. The blower assembly will be pre-assembled to the upper barrel assembly. The orientation will have the inlet and outlet opposed 180 deg. unless requested otherwise at the time of order. Other skids may contain afterfilter units or other accessory components. As soon as the equipment arrives, it should be carefully inspected to make certain all items on the packing list are present and in good condition. Even though the equipment is mounted on heavy shipping skids at the factory, damage can occur during shipment. Note damage or missing items on the Bill of Lading. The PURCHASER should take immediate steps to file reports and damage claims with the carrier. Damage to a unit in transit is the responsibility of the carrier since it is Clean Air Industries policy to make shipments FOB factory (i.e. ownership passes to the purchaser when the unit is loaded and accepted by the trucking firm). Any claims for transit damage or shortage must be brought against the carrier by the purchaser. Clean Air Industries will provide assistance to the purchaser if necessary.
4.2 INSTALLATION PLANNING
Selecting the proper location for your dust collection equipment is very important. See Figure 2 for typical installation details.
Certain items should be considered when locating the unit, such as: room to empty the dust storage container(s) or hoppers; shortest run for location of ductwork; electrical connections; wall penetrations; fan discharge direction; and afterfilters. Ease of maintenance should also be considered when selecting the location and orientation of the system
!!!!! CAUTION !!!!!
Do not locate dust collector near dust source in cases where the dust is explosive or a fire hazard.
!!!!! CAUTION !!!!!
In preparing to install the unit, ensure location is clear of all obstructions, such as utility lines or roof overhangs, so the crane is free to maneuver if needed.

4.2 Continued
The Clean Air Industries Amtech ATC Cyclone Dust Collector is usually mounted on a reinforced concrete foundation. Other mounting options are possible. Structural calculations for the foundation or other mounting arrangement must include the weight of the equipment. These weights must be considered together with wind, seismic and other live load ratings when designing the support structure. Interconnecting ductwork (not provided with the Cyclone Dust Collector) should be designed and properly sized to handle the air volume at the recommended air velocities of the entrainment of dust into the collection system. When installing ductwork, use shortest possible runs and long-radius elbows whenever possible. The shortest duct length with a minimum number of elbows will maximize the performance of the unit. Seal all joints. Follow ductwork design methods as listed in the Industrial Ventilation Manual as recommended by the American Conference of Governmental Industrial Hygienists. In the case of spark-producing processes, system design should incorporated measures to prevent live sparks from entering the dust collector. Consult local authorities for the location of this unit and any precautions to consider when collecting combustible, explosive or hazardous dusts. Review General Cautions listed on page 2. With any air-moving device, a certain amount of noise is created. Normally, the noise level is not as high as that of other machinery in the area. If you require an additional reduction in the noise level, exhaust silencers are available as optional equipment. Noise levels must be taken into consideration as you plan the installation of your equipment.
4.3 ASSEMBLY OF STANDARD EQUIPMENT
!!!!! CAUTION !!!!!
Use adequate safety measures when lifting and assembling any heavy components. Consult your plant safety personnel for recommendations.
Before you begin, remove all crating, strapping and hold-down bolts. Locate all hardware bags and other assembly materials provided with your unit. Remove fan housing inspection door and examine the unit fan wheel. Make sure it moves freely and is firmly in place. Re-tighten if necessary. Replace door after inspecting. Check that motor mounts are secure. Clean Air Industries Amtech ATC Cyclone Dust Collectors are typically shipped in three main assemblies: 1. Upper barrel assembly – This section consists of the upper barrel and blower housing with motor. 2. Cone weldment 3. The base assembly – This consists of support base, legs, drum cover, hose and clamps. The inlet and outlet pieces will also typically be shipped with the base assembly.

!!!!! CAUTION !!!!!
Never lift cyclone by the motor. Do not rest blower assembly on fan wheel. Use clevises (not hooks) on lifting sling. Use spreader bars on lifting sling.
HOPPER “THROW OUT BIN” AND SUPPORT STAND ASSEMBLY
(The hopper “throw out bin” is optional)
Place the Support Stand assembly of the Clean Air Industries Amtech ATC High Efficiency Cyclone Dust Collector in its desired location. Use shims under foot pads as needed to level unit. Once base is level, fasten down with properly sized anchor bolts.
!!!!! CAUTION !!!!!
In preparing to assemble the hopper to its mating support base, connect a lifting sling to at least four positions on the unit. Distribute the load evenly. Location must be clear of all obstructions such as utility lines or roof overhangs. Take care to use proper lifting equipment and procedures. Drift pins may be useful for locating hopper mating sections. With the hopper section still supported, use hardware to bolt the sections together. Once all hardware is in place, go back and fully tighten all hardware on mating pads and all bracing. Disconnect the crane. If your collector has a belt-driven blower wheel, DO NOT attempt to make any pulley changes. Each pulley is sized for proper operation prior to shipment. No changes should be made unless specifically directed by Clean Air Industries .
CONE ASSEMBLY
!!!!! CAUTION !!!!!
In preparing to assemble the cyclone to its stand or hopper, connect a lifting sling to at least four positions on the cyclone. Distribute the load evenly. Location must be clear of all obstructions such as utility lines or roof overhangs. Install the cone assembly by setting the cone on top of the base. No sealant is required at this joint for the 1 Drum and 2 Drum units. Sealant is required for hopper base units. The cones are symmetrical so there is no specific orientation to consider.

INLET AND OUTLET TRANSITION INSTALLATION
Each Clean Air Industries Amtech ATC High Efficiency Cyclone Dust Collector has its own bolt-on inlet and outlet transitions. Do not attempt to change the size of the inlet. If the cyclone is operated with more than the maximum permissible inlet area, the motor may become overloaded.
INLET AND OUTLET DIRECTION CHANGE
Check to be sure the inlet and the fan discharge are facing the desired direction. If not, they can be rotated. The inlets on the various models can be rotated at 45deg. increments. The outlet (fan housing) on all models can be rotated at 45 deg. increments. Once correct positioning is obtained, lay two (2) ribbons of sealant around the bolt circle of the fan housing and/or flange rings to ensure airtight seal. Re-bolt the fan housing. If discharge direction must be changed on the ATC series cyclones after unit has been delivered (or if collector must be moved), the upper cylinder/blower assembly must be re-oriented by unbolting, resealing and remounting as follows: 1. Loosen and remove the bolts holding the blower housing to the upper cylinder. 2. Rotate blower housing to the desired position. Housing may stick because of sealant. Scrape the old sealant off the barrel top and fan housing, then reseal using silicone sealant. Apply a ribbon of sealant on both sides of bolt pattern. 3. Reassemble parts in reverse order.
BARREL/BLOWER ASSEMBLY
Ensure that the inlet and outlet flanges are facing the desired direction. If the inlet and outlet directions need to be changed, see previous section “Changing Inlet and Outlet Direction” before continuing.
After ensuring that inlet and outlet direction are correct, use two (2) ribbons of sealant on each bolt-up flange.
4.4 ASSEMBLY OF OPTIONAL EQUIPMENT
DIRECT CONNECTION AFTERFILTER ASSEMBLY
On ATAF (afterfilter) models, the filter section is shipped in several containers. Transition, Plenum Sections, Filter bags and clamps. On all afterfilter models, use a ribbon of sealant between blower housing discharge flange and the mating flange of the afterfilter transition. If required, bolt afterfilter plenum to transition using additional sealant. Install proper ceiling supports or floor supports for the afterfilter housing.
Install filters with the appropriate clamps. Make sure bags and clamps are both on the flange collar of the plenum.

Position the drum assembly(s) under the unit, slide the hose up onto the discharge adapter collar on the cone and secure with a hose clamp.
4.5 ELECTRICAL INSTALLATION
!!!!! CAUTION !!!!!
All electrical work should be done by a qualified electrician in accordance with local codes. Disconnect electrical power before installing or servicing any electrical equipment. See Figure 3 for wiring connections.
Note: All electrical work must be performed by a qualified electrician according to the most stringent applicable codes. Be sure to use proper size starter, conduit and wiring for blower motor.
Start fan motor and visually check for proper rotation as indicated by the “rotation arrow” decal on the fan housing.
Note: While rotating backwards, the fan will still deliver approximately 40% of its rated air volume but will require more horsepower than proper rotation. It is extremely important to ensure proper fan rotation. If your collector has a belt-driven blower wheel, DO NOT attempt to make any pulley changes. Each pulley is sized for proper operation prior to shipment. No changes should be made unless specifically directed by Clean Air Industries .

OPERATION
5.1 Start-Up
!!! CAUTION!!!
The blower compartment bolt-on panel must be installed before operating the dust collector.
Inspect the installation area and make certain no tools, parts, etc. have been left anywhere on or inside the unit. Check the fan discharge to make certain it is free from all debris. Start fan motor and check for proper rotation. A rotation arrow is located on the fan housing. If the fan is rotating in the opposite direction, disconnect the power to the motor starter, interchange any two (2) wires on the output side of the starter (three- phase systems only), engage starter disconnect, then start fan and recheck rotation. Before each start-up, verify that hopper slide gates are closed. Clean Air Industries Amtech ATC High Efficiency Cyclone Dust Collector drum lids with gasketing and drums must be firmly in place and tight fitting. Ductwork slide gates must be open. Check exhaust for any obstruction. To operate the cyclone dust collector, simply turn on the blower.
Running fan in incorrect rotation for an extended period of
NOTE:
time will cause fan motor damage and reduce life of fan motor.
Adjust airflow with volume control damper(s) (not supplied by Clean Air Industries ) on individual ductwork drops.
5.2 CHECK LIST
Always verify that any hopper slide gates are closed and that the doors, drum lids and gaskets are in place. The material being collected will not separate from the airstream if any leakage occurs around the base or drum. Failure to adhere to these instructions may also cause the motor to overload. Verify that exhaust air remains visibly clean. If an emission develops, examine drums, drum lids, etc. for possible leaks.

6.3
SERVICING THE OPTIONAL BELT DRIVEN FAN AND MOTOR
!!! CAUTION !!!
All electrical work should be done by a qualified electrician in accordance with local electrical codes. Disconnect electrical power before installing or servicing any electrical component.
Periodically inspect the fan blades to ensure proper fan life. Clean the fan to remove any deposited material if required.
For motor maintenance, follow the manufacturer’s directions. If your motor re quires servicing under the motor manufacturer’s warranty, contact an authorized service center. Motors are greased at the factory and do not need lubrication at time of installation. However, regreasing may be necessary after 1000 hours of use. As a guideline, grease the motor every 3,600 hours with high grade ball and roller bearing grease. Recommended greases are Shell Dolium R or Chevron SR1#2. All bearings used are sealed, have been lubricated at the factory and do not need lubrication at the time of installation. Subsequent lubrication will be required and the motor and bearing manufacturer’s recommendations should be followed. Use the following instructions as guidelines. The fan bearings should be relubricated at six week intervals when utilized for eight- hour workday operations. The fan bearings should be relubricated more frequently if operation time is longer than eight hours per day. When lubricating, be sure to grease both bearings and use high grade medium weight ball bearing grease. It is also recommended that you consult your lubricant supplier regarding proper greases for both the motor and fan bearings. Proper grease should be based on hours of usage and environmental conditions.
If any bearing operates roughly, the unit should be shut down and the bearing replaced immediately.
6.4
BELT ADJUSTMENT AND REPLACEMENT/OPTIONAL
The belts on your new unit have been properly adjusted at the factory. However, before operating, it is suggested that belts be checked and re-adjusted if necessary. Recheck belts several times in the first days of operation and at least twice a month for the following six months. Thereafter, belts should be checked at each greasing. The drive used on this unit is equipped with banded belts and matching sheaves which transmit much higher horsepower per belt than older type belts.
Because much higher tension is required, it is advisable that the tension be checked with a tester or springs scale.
To adjust belts, loosen bolts on motor mounting plate, adjust tension screws on adjustment bracket in or out (depending on desired adjustment), then re-tighten bolts on motor mounting plate.
Page 16
sales@clean-air.com
1-866-665-1829
www.clean-air.com
Do not over tighten. Too much or too little tension will damage the drive belts and bearings. Check the tension frequently to be sure the deflection is at the value determined. To replace worn belts, loosen bolts on motor mounting plate and remove tension screws so the old belts can be removed from the sheaves. Remove the tension bracket and the bolts from the upper bearing bracket. Rotate the bracket 90 deg and remove old belt. Put new belt on and reverse the disassembly order to re-assemble.
Replacement belts should be ordered and installed in complete matched sets or one banded belt. Include old belt number(s) when reordering.
6.5
AFTERFILTERS
The afterfilter bags on the Clean Air Industries Amtech ATC High Efficiency Cyclone Dust Collector are semi-permanent and will give you long, efficient service if you perform routine maintenance. After each day’s operation, shake the filter bag(s) vigorousl y to remove the clinging material. If the afterfilter bag has a zipper-closed button, always empty the bag after shaking. Care should be taken to prevent tearing or puncturing the filter fabric. When adequate air volume cannot be restored by shaking the bags, simply remove them and replace with new filters. Under normal operating conditions, afterfilter bags should be replaced every two years for best performance. Be sure to include the model and serial number of your cyclone dust collector when ordering replacement afterfilter bags.
