Product characteristics

• 1 1/4" Connection
• 1Phase Power
• Energy efficient motors (R20-MD 0.75kw to 1.1kw)
• No wearing parts/maintenance free operation (inlet filter should be periodically checked for blockages)
• Smooth airflow delivery (no pulsations in the conveyed fluid)
• Modular design, easy to install (for proper use, the blower should be equipped with an inlet filter and pressure relief valve

A double stage impellor is mounted directly onto the motor shaft for contact-free compression. When the air enters the inlet port, centrifugal forces in the impellor blades accelerates the air outwards, and with every rotation results in a further increase of pressure finally discharged through the outlet port.
