1 AXIAL FAN Series Series К Series Axial fans of low pressure in steel case with the efficiency up to m 3 /h for a wall-mounted assembly Axial fans of low pressure in steel case with the efficiency up to m 3 /h for a wall-mounted assembly. Axial fans of low pressure in steel case with the efficiency up to m 3 /h for a vent duct assembly Application Combined supply and extract ventilation systems of premises for different destinations, where a high air flow capacity are required at relatively low resistance of the system. OV and OVK fans series can be used for the direct ejection of the exhaust air or static suction head ventilation in fire-prevention ventilation systems. It is possible to install OV and OVK fans series on external walls. Design The fan case and the impeller are made of steel body with polymeric covering. Terminal box of fans OV and OVK series has a cord for remote connecting. The fan VKF has an outward terminal block, mounted on the fan housing. Motor Two- and four-pole of one- or three-phase asynchronous motors equipped with built-in thermal protection on automatic restart are used. Application in the motors of ball bearings provides a long service life ( hours). Class of motor protection is IP 44. Speed control Smooth or step speed control is performed with thyristor or autotransformer controller. Several fans may be connected to one controller in case total power and operating current will not exceed rated values of controller (refer to the section Electronic Control Devices ). Mounting A fan is mounted on the wall with rectangular (OV series) or circular (OVK series) of joining plate. The VKF fan is set in a duct through connecting flanges. Fan is powered through a remote terminal box. Power connection and installation should be accomplished according to the manual and circuit scheme on a terminal block.
