Bldc Bypass Blower, 400W, 240V
120 or 240 VAC brushless blower with high flow fan system. Blower offers a fan system that can be used for either vacuum or pressure. The backward curved centrifugal impellers of the working air provide high efficiency operation. These blowers are suitable for use in 0-50°C. The drive system has a rectifier/filter network, a commutation controller and brushless DC motor. The drive system in the Bypass configuration has a cooling fan. In the Thru Flow configuration, the drive motor is in the working air stream.- .
- *Electrical Analog Voltage or Pulse Width Modulation Control:** The control signal input to an optical isolator provides maximum safety for the low voltage signal circuit. Application of a zero to 10 VDC will control blower speed and air performance. Control can also be achieved by application of a pulse width modulated zero to 10 VDC square wave at a frequency between 150 Hz and 400 Hz. It takes an increase in control voltage to restart the blower. **Mechanical Screwdriver Adjustable:** Adjustment of a multiple-turn potentiometer controls blower speed and air performance. The blower performance will vary from the maximum shown on the curves to a minimum of a few inches of water. **Features:**
