Series Vents KSK

APPLICATION

The fan is designed for ventilation of contaminated, grease-laden (using grease filters), humid and hot air with temperature up to 120 °C in conditions of high air resistance in the system. This fan model fits for the following applications:

• kitchen exhaust ventilation systems
• exhaust ventilation systems for removal of postwelding gases
• industrial bakery ventilation systems.

ELECTRIC MOTOR

Equipped with a highly reliable single-phase or three-phase motor with squirrel-cage rotor and steel highperformance centrifugal impeller with forward-curved blades (for sizes 150 to 250 mm) or backward-curved blades (for sizes 315 to 450 mm). The impeller is mounted on the motor shaft and is balanced statically and dynamically. The motor has F class motor winding insulation and IP54 ingress protection rating.

MOUNTING

The fan is designed for connection to round air ducts. The fan is fixed to the wall with the mounting bracket KM-KSK (separate delivery). The fan is connected to power mains on the terminal box on the motor. The cable length must be sufficient with respect to the motor-impeller block movement.

DESIGN DESCRIPTION

The fan casing is made of galvanized steel plate and is internally insulated with 50 mm mineral wool layer. The swivel block of the impeller and motor provides easy access to the fan internals for easy and effective cleaning.

The intake and exhaust flange diameter match with standard ventilation air ducts. The flanges are equipped with a rubber sealing. The fan is installed in the mounting frames with integrated vibration connectors.

SPEED CONTROL

Three-phase motors: Step speed control with transformer speed controller is available for all models.

Single-phase motors: non-adjustable.
