    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.
  • Page 8: Technical Data

    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.)
  • Page 9 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.

    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.
  • Page 21: Installation Procedure

    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.
  • Page 22 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.
  • Page 23: Start-Up

    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.
