Inline fans

Applications

• Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.
• Exhaust or supply ventilation depending on the fan mounting type in the system.
• Designed for PVC ducting systems or flexible ducts.
• Low to medium air flow motion for short distances at low air resistance.
• Compatible with 150mm air ducts.

Design

• The casing and the impeller are made of high-quality durable ABS plastic, UV resistant.
• The intellectual impeller design makes the fan efficiency high and the service life long.
• Protection rating IP X4.

Motor

• Reliable and low-watt electric motor.
• Designed for continuous operation and requires no maintenance.
• Equipped with overheating protection.

Control

Manual:

• The fan is controlled by a room light switch. It is not included in the delivery package.
• Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may connected to the same regulator unit.

Automatic:

• By the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.

Mounting features

• The fan is mounted into a matching duct size. Fastening with clamps in case of flexible duct connection.
• This series fans have different inlet and exhaust flange diameters to enable attachment of the decorative grille MV to the appropriate intake flange diameter in case of direct installation into the ventilation shaft or instead of the existing ventilation grille.
• The fan can be mounted on a horizontal or vertical flat surface by a fixing bracket (VKOk model).
• Two fans can be installed in series for higher performance.
• For 12 V low-voltage motor fan connection to 220 V / 50 Hz power mains use the step-down transformer TRF 220/12-25 that is available upon separate order.
