Working Mechanism:
- Connect the blower to a 115VAC power source using the appropriate power cord and ensure a stable electrical connection.
- Turn on the blower using the power switch or control panel, activating the 1 hp motor.
- The motor drives the axial fan at a high speed of up to 3425 rpm. As the fan blades rotate, they draw in air from the surrounding environment.
- The rotating blades create a low-pressure zone near the inlet side of the blower, allowing ambient air to be drawn into the blower unit.
- The captured air is accelerated and directed towards the outlet side of the blower as it encounters the high-speed rotating blades.
- The accelerated air is forcefully discharged through the blower's outlet, creating a strong and consistent airflow.
- The generated airflow can be directed towards the desired area or connected to ventilation ducts for efficient air distribution in confined spaces or work environments.
Compatible Accessories:
- Allegro Lay Flat Ducting: These clear polyethene lightweight air ventilation tubing are designed to deliver high volumes of forced air effectively to confined areas.
