Blauberg Iso-V 450 4E

Supply and extract ventilation systems installed in premises with high requirements to the noise level. Various application possibilities due to a special transformable casing design. Suitable for use as separate components of air handling systems. Compatible with Ø 355 up to 710 mm round or 500x500 up to 1000x1000 mm rectangular air ducts.

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. Square to square vibration absorbing connectors (AKV series) or square to round connector-reducers (ARV seris) may be connected to the fan (available upon separate order). The round spigot of the ARV connector-reducer is rubber sealed for air tight connection.

Four- or six-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. 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 model Iso-V 355 4E incorporates thermal switches with automatic restart. Dynamically balanced impeller.

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. In case of outdoor mounting the fan may be equipped with the upper protecting cover (RSD-IV series) or the outer hood (AH-IV series) to be installed at air inlet/outlet.

max: high-powered motor.
