6. FEATURES
6.1 Standard
6.1.1 FIRE RETARDANT CARTRIDGE FILTERS – The filters have been treated with a chemical to “retard” against chemical combustion; however, the cartridge filters are NOT “fire proof”, th at is, under certain the filters will combust.
6.1.2 METAL CONSTRUCTION – The unit is constructed of 7 and 11 gauge carbon steel. This fabrication technique results in a robust unit capable of withstanding the rigors of reverse jet cleaning.
6.1.3 REVERSE JET CLEANING – The unit is equipped with a compressed air manifold and 1" valves which upon activation by the pulse control box, opens the valve and delivers a short burst of air into the clean side of the filter. The temporary reverse flow of air dislodges accumulated dust on the filter which slowly migrates towards the settling chamber. 6.1.4 TURBO DIGITAL PULSE CONTROL – This electronic device constantly monitors the differential pressure across the cartridge filters and, when the programmable set point is met, automatically reverse pulse cleans the cartridge filters. The unit also offers a cycle down feature, whereby the filters are cleaned on shutdown. 6.2 Optional 6.2.1 AFH/AFS - After filter housings are available with either HEPA or Safety filters. HEPA filters are 99.97% efficient at specified flow/pressure rates and Safety filters are 95% efficient at specified flow/pressure rates.
6.2.2 DRUM LID KITS – Drum lid kits provide an "air tight" connection between the 14" opening on the hopper and 5, 10, 20, and 55 gallon drums.
6.2.3 FIRE SUPPRESSION – Fire suppression is available in a variety of technologies. Fire suppression systems should be installed by qualified individuals and in accordance with any local, state, or national codes/regulations/laws (if any). 6.2.4 HOPPER ACCESS DOOR – Hopper access doors provide an avenue for quick entry into the bottom of the collector. This option is most helpful when bridging of material is problematic or frequent access is necessary. 6.2.5 PNEUMATIC VALVE KIT - A pneumatic valve kit includes a pressure regulator, coalescing filter, and pressure gage. This kit helps insure that clean dry air is being supplied to the pulse valves at the proper air pressure. NOTE: The coalescing filter requires periodic maintenance/replacement (life span is a function of supplied air quality). 6.2.6 RUPTURE PANELS – Explosion/rupture panels are available for all units for combustible dusts with a Kst of less than 200 (8 bar Pmax). An Explosion Vent is designed to relieve rapid pressure build up, as is experienced from a deflagration within the dust collector. If your rupture panel should experience a burst, then contact your Clean Air Industries Distributor to order a replacement. 6.2.7 SLIDE GATE – The slide gate option allows for continuous operation when emptying the contents of 5-55 gallon drum dust containers.
