The VES-Artex shutter exhaust fan is a robust, durable, and effective exhaust fan. It is ideal for factories, warehouses, garages, attics, agricultural and horticultural applications Construction highlights include corrosion-resistant shutters, a shutter tie bar which reduces shutter flapping and opening unnecessarily, a fully enclosed CSA/CSA-US approved motor, and balanced silicon steel rotators which reduce noise vibration. The bearings are designed to handle temperatures from -40⁰F to 284⁰F. The motor seal, switch, and wiring connections have a moisture-resistant rubber gasket. Available as a single or three-speed model, each shutter exhaust fan comes fully assembled and connected to a 9’ (2.7m) power cord (120V) which means an electrician is not needed for installation; simply plug the fan in and turn it on.
