Blauberg Iso-VK 450 4E

Designed to extract contaminated hot air up to 120 °C, containing grease (when using grease filters), in high resistance conditions.Ideally function in various ventilation systems for restaurant or café kitchens, industrial bakeries, removal of gases generated during welding operations.Various application possibilities due to a special transformable casing design.Compatible with ∅ 315 up to 800 mm round or 500x500 up to 1175x1175 mm rectangular air ducts.

Highly reliable single-phase or three-phase motor with steel high-performance centrifugal impeller with backward curved blades.The motor is maintenance free.Motor insulation winding class – F.Degree of protection – IP55.

Casing made of aluminium frame and removable aluzinc thermal- and sound-insulated double-skinned sandwich panels.Casing internally filled with 20 mm non-flammable mineral wool.Position of the removable panels can be adjusted to inline air flow or 90° angle air flow.Due to corrosion-resistant casing and thermal insulation the fan is suitable for external mounting.The electric motor, located outside the air flow, is mounted on an additional panel inside the fan.

Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).

The fan is mounted with rectangular or round air ducts.Connected to air ducts with flexible vibration-absorbing connectors or connecting reducers of respective diameters.Power is supplied to the fan through an external terminal box.The fans can be installed in any mounting position with respect to air flow direction in the system. While mounting provide enough servicing space.
