AC blowers are more forceful under pressure

Answers increasing requirement for backward-curve impellers in applications where high packing density creates a high system pressure that restricts airflow.

The Comair Rotron Diplomat range of high-power backward-curve impellers, available in the UK from Aerco, has been extended and now includes AC blowers for the first time.

Ideal for pressurisation or evacuation of enclosures in a variety of applications the range provides high airflow in high-pressure environments and range in sise from 100 to 280mm.

These blowers provide airflow of up to 472 litre/s against a system pressure of up to 7.5mbar.

DC versions are available in 12, 24 and 48V, and the AC blowers are 115 or 230V.

There has been an increasing requirement for backward-curve impellers in many applications such as telecommunication equipment, computers, medical devices, heating and air conditioning, refrigeration, heat exchangers, power supplies and others where high packing density creates a high system pressure that restricts airflow.

Unlike many other centrifugal types of air movers Diplomat blowers do not require a scroll housing to obtain high static pressure.

They are available with a variety of options including tachometer, fan performance sensors and speed control.
