1. Safety 1.1 General Safety Precautions WARNING: Improper operation of 3BA units can result in serious or even fatal injuries. Please make sure all personnel have read and understood this manual before operating the unit. All personnel should familiarize themselves with the units’ specifications and be careful not to exceed the unit’s capacity.
1.4 Vacuum and Gauge Pressure Safety In order to avoid dangerous situations associated with vacuum and gauge pressure, please utilize secure mounting elements, connections, lines, fittings, and containers. Pipes/hoses must be securely connected to the inlet and discharge connections. The inlet and discharge connections and the pipes/hoses connected to them must not be closed, clogged, or soiled.
If the unit is installed or stored in an environment with a temperature of over 104° F (40° C) be aware that the winding may be damaged and the grease might need to be changed more often. 1.6 Maintenance Procedures Before beginning work on the pump-motor unit, please take the following precautions: •...
Please consult the table on page 27 to find the weight of the unit being handled. Do not stand or walk under suspended loads. If a 3BA unit has come in contact with any dangerous substances, it must be decontaminated before being sent to Airtech for repair evaluation.
The seal between the bearing and the motor is not gas tight in most models, therefore these blowers are not recommended for handling of toxic or explosive gases. (Contact Airtech Vacuum, Inc. for additional options if explosive or toxic gases will be handled.)

CAUTION! Dangerous (flammable or explosive) or aggressive (corrosive) gases should not be handled by the standard blower. Handling of flammable or aggressive gases and vapors may be possible by using a specially configured or modified blower. Contact factory for additional information.

Operation of any blower is possible at 87 Hertz without modification in most cases. When using a VFD to operate the blower at this frequency, refer to the nameplate for limits on vacuum and pressure, current draw and motor performance. If your specific model number is not listed above, please consult the nameplate on the unit for electrical data.

3. Installation As illustrated in Figure 1, the Airtech 3BA blower can be installed in any physical configuration. CAUTION! Regenerative blowers can have surface temperatures in excess of 320° F. To avoid burns or other physical injury, take care to avoid contact with the surfaces of the blower during and immediately after operation.
CAUTION! Design your piping system to avoid unnecessary pressure loss, which may significantly affect the operation of any regenerative blower. Contact your Airtech representative for assistance in designing and configuring an appropriate piping system for your application. For alternation between vacuum and pressure in any application, changeover valves are available.

3. A magnetic motor starter should always be used to connect the motor to the power supply. It is advisable to use thermal overload motor starters to provide maximum protection for the motor and wiring. All cabling used on starters should be secured with good quality cable clamps.
4. Start-up CAUTION! Do not start the blower motor more than 10 times in one hour. If multiple and frequent start-ups are required by your application, install a minimum run timer in the motor control circuit to avoid decreased motor life and possible fire due to over-starting of the motor.
5. Maintenance and Servicing WARNING! Be sure the power supply is disconnected and locked out before attempting to do any maintenance on the unit. It is critical that the unit be locked out from starting during maintenance as severe injury or death could result from exposure to high voltage or rotating parts.
