Blauberg Box 60x35 4D
Supply and exhaust ventilation systems installed in various premises.Compatible with 400x200 up to 600x350 mm rectangular air ducts.DESIGN
Atmospheric resistant galvanized steel casing and impeller.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 fan is equipped with a built-in terminal box with a leaded outside sealed electrical lead-in for connection to power mains.
SPEED CONTROLSmooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).
Two- or four-pole asynchronous motor with external rotor and centrifugal impeller with backward curved blades.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 automatic restart or with leaded outside terminals for connection to external protecting controls.
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. The fan is suitable for mounting into round duct at intake flange with a round reducer (available upon separate order).If vibration-absorbing flexible 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.
