MB blowers are used for applications where slightly dusty air has to be removed.
The fan is suitable for handling air up to 80°C.
A protection hood is required for outside use.
Composition
The casing is made of spot welded sheet steel and painted in epoxy RAL 7031 with a total thickness of 80µ. The strong base frame support the motor
The impeller with forward curved blades is dynamically and statically balanced grade G6.3 according to ISO 1940/1. The many concave blades (30 or more) gives a great air volume at low speed which is benefit to a low noise level.
Totally closed squirrel-cage asynchronous motor
Protection IP55 – Insulation F
