Application
The fan is designed to deliver the air to the furnace of the central-heating solid fuel boiler. May be used for ventilation of premises and processing equipment.
Design
Casing material is steel with polymeric coating. The fan inlet is protected by a grid. The fan outlet is flanged. A gravity damper installed on the outlet side of the fan blocks air access to the boiler when the fan is turned off.
Motor
The impeller with forward curved blades made of galvanized steel is powered by a 4-pole single phase motor with an external rotor. The motors are equipped with built-in thermal overheating protection with automatic restart. The motor is equipped with the ball bearings for long service life. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembling. Motor protection rating IP 44.
Speed control
Both smooth and step speed control is performed with the thyristor or autotransformer controller. Several fans can be connected to one controller in case the total power and operating current do not exceed the controller rated values.
Mounting
Fixation with screws to the air duct wall by means of the flange with the sensing element located the air stream. Power is supplied by means of the external terminals. It’s advisable to use a gasket between a flange and a boiler to prevent air losses.
