Product Overview | Turbo Blowers
FEATURES — Direct drive blowers specifically for combustion
Altitude, air temperature, and air composition affect blower rating-pressure, capacity and horsepower. For blower selection and performance at elevated temperature or altitude significantly above sea level, the blower section of the North American Combustion Handbook is recommended as a guide to select the proper blower and motor combination. Generally standard motors can be used up to 3300 feet (1006m) above sea level; special construction is recommended above 3300 feet (1006m). Do not use Series 2300 blowers above 200 °F (93 °C). See Bulletin 2600 for applications that require operational temperatures greater than 200 °F (93 °C). CONSTRUCTION Series 2300 blowers are available in direct drive design where the impeller is mounted on the motor shaft (AMCA Arrangement 4) for simplicity with minimal maintenance. An all metal construction including mild steel, cast aluminum, or corrosion resistant stainless steel creates a robust, dependable blower allowing for years of trouble-free service. Fabricated aluminum or steel impeller designs based on lightweight aerospace technology provide significant benefits; high motor bearing life which extends the life of the overall motor; low starting inertia which allows fast starting times and hence does not require the oversized motors of some alternate designs. All Series 2300 impellers are low stress and in the case of multi-stage units significantly reduce stress by dividing pressure generation between multiple impellers. Individual impeller dynamics are assured, by either single or two plane balancing to ISO Grade 2.5, minimizing vibration and assuring longer bearing life. Completed blowers are individually tested prior to shipment to assure correct and trouble free operation. Completed blower assemblies composed of motor, base, casing, and impeller are tested in accordance with ANSI/AMCA Standard 204-20 BV-3 Fan Application Categories
applications, which are also an excellent choice for uses such as pressurized air supply, drying, conveying and other application in process industries. — Available in single or multiple stage designs in direct drive configurations at 3600 rpm; the Series 2300 blowers are capable of performances not achieved by any other com- parable blower design. Consult Fives North American for specific requests for 1800 RPM blowers. — Horsepower and impeller selection are designed to achieve "flat" pressure performance curves to minimize variations over the operating range of the blower (i.e low-flow condi- tions). (Custom blowers are available with options for in- creased efficiency with steeper pressure curves and with variable frequency drive capable blowers). — All 60 Hz blowers are equipped with Premium Energy Efficient Motors which meet the requirements of EISA (except units with fractional 56 frame and see Series 2300- 50 cycle for 50 Hz motor standards). — Full array of accessories include; filters, silencers, filter/ silencers, inlet and outlet adapters, flexible sleeves, inlet vane dampers, AC frequency drives, combination motor starters and fusible disconnects. These options offer the protection needed to keep operational costs down while increasing blower life expectancy. SELECTION Pressures and volume flow at air density of 0.075* pounds per cubic foot (1.2 kilograms per cubic meter) are shown on the following pages of this bulletin. It is wise to allow some capacity safety margin when choosing a blower based on the calculated cfm requirements. Unanticipated piping leaks, variation in burner capacity, changing process back pressure and other unforseen factors could cause motor overload unless there is some cushion. Without prior knowledge of leakage and other conditions, a 10% safety margin is considered minimum. It is also important to allow for pressure losses in piping, fittings and valves which reduce pressure available at the burner (or other end use). For volume flows greater than shown in the bulletin consult North American for custom selections designed to the exact requirements of the application-see "2300 Custom" section of this bulletin.
Strategically positioned mounting locations allow for in-field rotation of casing discharge position, for info see page 7.
Standard shaft motors on most single stage blowers reduce replacement downtime in the field.
Inlet or outlet adapters are not included as standard supply but may be specified at an additional cost.
