The VKOP 2 fan provides direct supply of outdoor air from the space above the roof to stairwell and elevator areas, creating overpressure that prevents smoke from entering these zones during a fire. This simplifies the overall ventilation system and frees up usable space on the technical floor.

VKOP 2 roof units are equipped with built-in double-inlet radial fans with a belt drive. The fan is placed inside a block assembled from durable panels. Air from the spiral housing is directed downward into the air duct or directly into the serviced area. The two side panels of the block feature louvered grilles positioned opposite the fan’s inlets, providing reliable protection against atmospheric influences and ensuring stable operation in all conditions.
