Application

CHVB / CHVT fan range is used in both general ventilation systems and for hot smoke extraction occurring in conditions of fire.

These fans are also designed to work in industrial kitchen ventilation, parking spaces, public buildings, wherever facilities are equipped with filter systems, valves.

Construction

Fans are manufactured according to EN 12010-3 standard. Centrifugal fans with direct drive, with motor mounted outside the airflow.

Pumped medium temperature is 400°C/2h or 120°C or in a continuous operation.

Fan housings are made of galvanized steel sheet, with sandwich panel type and fireproof acoustic insulation of fibreglass (M0), 25 mm thick. Impeller with backward curved blades.

Electric motor

All models are supplied with electrical junction box. Single-phase motors 230V-50Hz (CHVB), or three-phase motors 230 / 400V 50 Hz (CHVT). Insulation class F, protection degree IP55.

Possibility to use thyristor regulators of REB type and transformer controllers of RMB / RMT type.

Three-phase motors can also be adjusted with frequency inverter.
