ERV-2022-28-2,5 with electric engine 0.37 kW 3000 RPM

Purpose of the EPV-2022 fan

Electric hand fan ЕРВ-2022 was developed by KB LLC "Kiev ventilation plant" in 2022 directly during military operations during Russian aggression against Ukraine as an analogue of morally and technically obsolete fan ЕРВ-49. This fan is designed for ventilation of shelters, civil and military defense facilities that do not have autonomous power supply system.

Additional information about the ERV-2022 fan

The peculiarity and advantage of fan operation by electric drive is that the reducer is not disconnected from the impeller shaft, but works already in articulated position and does not require additional actions to articulate the motor shaft with the reducer at the moment of switching to manual mode. In the absence of electric power the operation of the fan is carried out by rotation of the reducer handle.

Advantages of ERV-2022 (analogue of ERV-49):

The first models of electric manual fans for shelters were presented in 1949. But this model ERV-49 became morally and technically outdated: the fan had a large weight, low efficiency, a heavy load for a person in manual operation, its execution in one direction of rotation and one angle of rotation of the cochlea made it extremely inconvenient for operation and installation. And most importantly: ERV-2022 fan, unlike ERV-49, does not require any additional connections and actions to connect the gearbox to the electric motor. To switch to manual mode, you just need to connect the handle. The next undoubted advantage of this fan is its power. It is twice as big as ERV-49, which means that for manual operation, one person's efforts are enough to ventilate a much larger room.

Recognition of ERV-2022:

Electric manual fan ERV 2022 is specially designed for ventilation of civil defense premises, bomb shelters, without autonomous power supply systems, as well as to provide reliable ventilation of bomb shelters and military and civil defense facilities equipped with diesel generators in case of their failure or limited ability to work in time.

Design of the electric manual fan ERV-2022:

The design of the electric hand fan ERV 2022 is a body made of durable structural steel, a frame, a special gearbox and an electric motor. The fan can operate both from the electric motor and from manual rotation of the gearbox handle. The motor is permanently coupled with the gearbox and does not require additional half couplings. When the motor is not running, ventilation can be organized only manually - by rotating the gearbox handle. The fan is made of left direction of rotation. Usually the electric manual fan should be installed at a distance of 1125 mm from the floor level to the motor axis. Operation of the electric hand fan ERV 2022 is possible in the mode of normal (clean) ventilation (mode I) or in the mode of filter ventilation and regeneration (modes II and III).
