Blauberg Box-F 90х50 6D
Supply and exhaust ventilation systems installed in various premises. Compatible with 400x200 up to 1000x500 mm rectangular air ducts.
Atmospheric resistant galvanized steel casing and impeller.The fan is rated for continuous operation.Fitted with standard 20 mm connecting flanges for connection to rectangular air ducts. Access cover on the casing for inspection and maintenance operations.The fans with standard size from 40x20 up to 60x35 are equipped with a terminal block integrated into the casing with leaded outside sealed electrical lead-in for connection to power mains. The fans with standard size from 70x40 up to 100x50 are equipped with an external terminal block for connection to power mains.
Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).
Four- or six-pole asynchronous motor with external rotor and centrifugal impeller with forward curved blades.Due to its turbine design the fan has excellent air dynamic charakteristics (high performance and pressure drop).Single-phase (E) or three-phase (D) motor modifications. Equipped with ball bearings for longer service life. Dynamically balanced turbine.Overheating protection by built-in thermal switches with leaded outside terminals for connection to external protecting controls.The thermal switch terminal leads are designed for connection to respective circuit ot the overload relay or respective terminals of the autotransformer or thyristor speed controller.
The fan is designed for mounting inside rectangular air ducts and can be installed in any position. The fan flanges are connected to the air ducts through the bolts inserted into the flange holes. Mounting to a round air duct on exhaust flange through a round pipe reducer. Available upon order. If flexible vibration-absorbing connectors are used to connect the fan to the air ducts provide their fixation to mounting structures with supports or brackets. While mounting provide enough space for accessing the cover for service operations.
