Ametek Windjammer 117417-01
Product Name
Windjammer 5.7 Inch Brushless DC Bypass Blower
Product Introduction
This blower is a 5.7 inch brushless DC air-moving device for continuous-duty industrial and medical applications. It uses a three-stage bypass design with closed-loop speed control and an integrated controller interface.
Detailed content
Technical Specifications
Rated voltage is 120 VAC. Power level is 800 W. Frame size is 5.7 inches, equivalent to 145 mm. Stage count is three. Maximum flow is approximately 82.5 SCFM, equal to 140.2 m³/h. Maximum pressure is approximately 127.3 inH₂O, equal to 31.7 kPa. Inlet tube diameter is 1.25 inches. Electrical connection uses a 5-cavity post header with power leads and 0 to 10 VDC speed command leads.
Functional Features
Speed control accepts 0 to 10 VDC command. Closed-loop regulation maintains set speed under load change. Brushless motor construction supports long service intervals. The blower includes mating connector assemblies for installation.
Application Scenarios
Use the blower for medical and dental air systems, laboratory air sampling, fume evacuation, material handling, and business-machine or packaging ventilation where controlled pressure and flow are required.
Material Composition
The housing uses industrial blower-grade plastic and metal hardware. The motor uses brushless DC internals with encapsulated controller electronics. Supplied connector kits provide power and control termination.
Working Principle
AC input is converted by the internal controller to drive the brushless motor. The impeller generates airflow through the bypass stage path. The controller adjusts motor speed from the 0 to 10 VDC command and feedback to maintain target flow or pressure.
Installation Requirements
Mount the blower on a stable bracket or equipment frame with clear inlet and discharge paths. Use the specified 1.25 inch inlet connection. Separate power and 0 to 10 VDC control wiring to reduce electrical noise. Verify cooling air around the motor and controller.
Usage Precautions
Do not block the inlet or discharge. Confirm the 0 to 10 VDC command source before energizing. Avoid sustained operation beyond rated pressure and flow. Inspect connectors and seals during preventive maintenance.
