AXIAL FANS Series VENTS OV Series VENTS OVK Series VENTS Low pressure axial fans in the steel casing with the air capacity up to 122 m 3 /h for wall mounting Low pressure axial fans in the steel casing with the air capacity up to 122 m 3 /h for wall mounting Low pressure axial fans in the steel casing with the air capacity up to 119 m 3 /h for vent duct mounting Applications Combined supply and exhaust ventilation systems for various premises where high air capacity at relatively low system resistance is required. OV and OVK fans can be used for the direct air exhaust or pressurization in smoke ventilation systems. OV and OVK fan are suitable for outdoor wall mounting. Design The fan casing and the impeller are made of steel with polymeric coating. OV and OVK fan terminal box is equipped with the cord for remote connection. fan is fitted with the external terminal box mounted on the fan casing. Motor The impellers are powered by two-, four- or sixpole, single or three phase asynchronous motors with external rotor and built-in thermal overheating protection depending on the model. Ball bearings in the motor provide long service life designed for at least 4 hours. Motor protection rating IP 44. Speed control Both smooth or step speed control is performed by means of the thymistor or autotransformer controller. Several fans can be connected to one controller if the total power and operating current do not exceed the rated controller values. Mounting Fan is installed on the wall surface by means of a square (OV series) or round (OVK series) mounting plate. fan is installed into the duct by means of connecting flanges. The fan is powered through the external remote terminal box. Power supply and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
