Combined supply and extract ventilation systems for various premises where high air capacity at relatively low system resistance is required. OV1 and OVK1 fans can be used for the direct exhaust of air.
OV1 and OVK1 fans can be mounted onto the external walls. OV1, OVK1 and VKOM fan casings are made of steel with polymeric coating. VKOMz fan casing is made of galvanized steel and the impeller is made of aluminum. The terminal box is fitted with a cord for remote connection.
Single-phase asynchronous motor with external rotor is equipped with thermal overheating protection with automatic restart as well as ball bearings for long service life. Motor rating protection IP 44.Speed control both smooth and step speed control is performed with the thyristor or auto transformer controller. Several fans can be connected to one controller in case the total power and operating current do not exceed the rated controller values.
The fan is installed on the wall surface by means of square (OV1 series) or round (OVK1 series) mounting plate. VKOM or VKOMz series fan is installed into the duct by means of clamps or directly inside the wall. The delivery set of VKOMz includes fixation brackets. The fan is powered through the remote terminal box. Power supply and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
