The Vents VCN 125 fan is used for exhaust ventilation of air with temperatures up to 55°C. Maximum productivity up to390 m3/h. Designed for outdoor installation, the fan housing is mounted directly on a flat wall surface. It is possible to adjust the fan performance using thyristor regulators (not included in the delivery set, purchased separately).

Charts
Design
The housing made of steel with a polymer coating protects the engine from direct moisture when mounted outdoors . The lower part of the fan has a protective grille against small birds and rodents. The air is exhausted vertically downwards.
Motor
The single-phase external rotor motor is equipped with a centrifugal impeller with backward curved blades. The engine is equipped with built-in thermal protection with automatic restart. The use of rolling bearings in the engine ensures a long service life (40,000 hours). To achieve precise performance, low noise levels and safe fan operation, each turbine undergoes dynamic balancing during assembly. The motor in the fan has a protection class of IP 44.
Speed adjustment
Smooth or step adjustment is carried out using a thyristor or autotransformer. Several fans can be connected to one control device simultaneously, provided that the total power and operating current do not exceed the rated parameters of the controller.
It is possible to use a speed controller (supplied separately) RS-1-300
Installation
Fan Vents VCN 125 is designed for installation on the outer surface of a wall and connection to a round air duct of the appropriate diameter. Power is supplied to the fan through external terminals. Electrical connection and installation must be carried out in accordance with the instructions and electrical diagram specified in the product passport.
