VS 500 4E

Supply and exhaust ventilation systems for various premises with high noise level requirements.

The VS fan design enables to assemble various ventilation configurations due to changeable positions of the removable panels.

Such design enables air supply in all directions, both linearly and at the angle 90 °C.

The aluzinc casing with high corrosion-resistant properties and heat-insulating material allows outdoor installation of the fan.

The fans may be integrated into an assembled supply ventilation system.

The fan casing is made of aluminium frame, fastened with aluminium bends and removable double-skinned aluzinc panels, heat- and sound-insulated with 20 mm non-combustible mineral wool.

The connecting pipes that also serve as vibration absorbing connectors are available with round and square sections.

The round pipes are fitted with rubber sealing rings. 

The connecting pipes are not included into the delivery set and are available upon separate order! 

4- or 6-pole asynchronous external rotor motor and centrifugal impeller with backward curved blades.

The motors are equipped with overheating protection, which is connected to the external protection device (i.e., the model VS 355-4E has thermal switches with automatic restart).

Smooth or step speed control with a thyristor or autotransformer speed controller.

Speed control is adjusted by the supply voltage regulation.

Air flow is regulated by the motor speed.

Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.

Inline fans are designed for connection to rectangular or round air ducts with a flexible connector of respective cross section.

The fan are designed for inline mounting.

While connecting the fan to flexible connectors, provide its fixing to a building with supports, suspension or fixing bracket.

The fan is suitable for any mounting position, on condition that the pointer on the fan casing matches the air motion direction in the system.

While mounting the fan provide enough access for its servicing.
