ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm

Purpose of the ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm fan

The ERV-2022 electric manual fan was developed by the Design Bureau of Kyiv Fan Plant LLC in 2022, directly during the hostilities in the period of Russian aggression against Ukraine, as an analogue of the morally and technically outdated ERV-49 fan. This fan is intended for ventilating shelters and civil and military defense facilities that do not have an autonomous power supply system.

Additional information about the ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm fan

A special feature and advantage of operating the fan from an electric drive is that the gearbox does not disconnect from the impeller shaft, but operates already in a connected position and does not require additional actions to connect the motor shaft to the gearbox when switching to manual mode. If there is no power supply, the fan operates by turning the gearbox handle manually.

Advantages of ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm (analogue of ERV-49)

The first models of electric manual fans for shelters were introduced back in 1949. But the ERV-49 model became morally and technically obsolete: the fan was heavy, with low efficiency, high load for a person during manual operation, designed only for one rotation direction and one casing rotation angle, which made it extremely inconvenient for use and installation. Most importantly: the ERV-2022 fan, unlike the ERV-49, does not require any additional connections or actions to couple the gearbox to the electric motor. To switch to manual mode, simply attach the handle. Another indisputable advantage of this fan is its power. It is twice that of the ERV-49, which means that for manual operation, the effort of one person is enough to ventilate a significantly larger room.

Purpose of ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm

The ERV-2022 electric manual fan was specially developed for ventilating civil defense premises, bomb shelters without autonomous power supply systems, as well as for ensuring reliable ventilation of bomb shelters and civil and military defense facilities equipped with diesel generators, in case of their failure or limited operation.

Design of the ERV 2022-75 #4 w/motor AIR 71 A6 0.37 kW 1000 rpm electric manual fan

The design of the ERV-2022 electric manual fan consists of a housing made of strong structural steel, a frame, a special gearbox, and an electric motor. The fan can operate from an electric motor or from manual rotation of the gearbox handle. The motor is constantly connected to the gearbox and does not require additional couplings. When the motor is not running, ventilation can only be organized manually — by turning the gearbox handle. The fan is made with left-hand rotation. Typically, the electric manual fan should be installed at a distance of 1125 mm from the floor level to the motor axis. The ERV-2022 electric manual fan can operate in pure ventilation mode (Mode I) or in filter ventilation and regeneration modes (Modes II and III).
