APPLICATION

Fan designed for polluted air exhaust systems and pneumatic transport. Typical applications:

• local exhaust systems, dehumidifiers, drying systems,
• transport of shavings, sawdust, granulates,
• combustion gas exhaust systems.

CONSTRUCTION

• medium-pressure, centrifugal fan with direct drive,
• aluminum alloy impeller with straight blades (models to 800, from model 900 to 1500 the impeller is welded from steel sheet), dynamically balanced in accordance with ISO1940-1,
• welded sheet steel housing,
• rectangular from model 60 to 600,
• spiral from model 700 to 1500,
• motor support in models from 500 to 1500,
• painted in RAL 5010 (corrosivity category C3),
• maximum medium temperature 80^oC,
• ambient temperature range from -20^oC to +40^oC,
• standard RD90 positions in models from 60 to 400,
• standard LG270 positions in models from 500 to 1500.

MOTOR

• asynchronous single-phase 230V 50Hz (power to 1,1 kW),
• asynchronous, three-phase 230V/400V 50Hz (power to 3 kW),
• asynchronous, three-phase 400V/690V 50Hz (power from 4 kW),
• efficiency class IE3 (from 0,75 kW),
• degree of protection IP55,

• impeller, housing and support made of stainless steel 1.4301,
• impeller, housing and support made of acid-proof steel 1.4404,
• different motor voltage and frequency,
• single-phase motor driven by voltage,
• different motor degree of protection,
• motor equipped with sensors or additional cooling,
• radial shaft sealing,
• maximum medium temperature above 80^oC,
• ambient temperature range below -20^oC and above +40^oC,
• belt drive,
• sound-acoustic isolation.
