Axial window fans VF (or VAF) are intended for aeration of work rooms, industrial halls, livestock farms. The working environment is generally dust-free atmospheric air, with a maximum humidity of 60% at an ambient temperature of + 20ºC. It is executed in normal or antiex construction.
Although they are intended to be mounted in windows, they can also be installed in the walls of rooms or industrial halls, making a direct connection with the outside where it exhausts the vitiated air inside. Depending on the mounting position, they can evacuate the air from the inside to the outside or they can introduce fresh air from the outside to the inside. Therefore, in spaces that do not have adequate ventilation possibilities or where a surplus of fresh air is needed, it is recommended to install these VF fans in pairs, so that one removes a defective air volume and the other, forced and at the same time introduces the same volume of fresh air.
