ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm

Purpose of the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan:

The ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm electric manual fan was developed by the Design Bureau of Kyiv Fan Plant LLC in 2022, directly during the war in the period of Russia's aggression against Ukraine, as an analogue of the morally and technically obsolete ERV-49 fan. This fan is intended for ventilating shelters and civil and military defense structures that do not have an autonomous power supply system.

General information about the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan:

• Increased, very high efficiency (85%) to reduce the load during manual operation
• Medium pressure
• Single-sided suction
• Spiral rotary casing, the necessary angle of casing rotation can be selected during installation
• Rotation direction — left or right
• Drive — manual and electric

Operating conditions of the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan:

Ambient temperature from -40 C to +40 C, moderate climate, placement category 2 or 3. It is also possible to manufacture a special version of the fan for tropical climates and conditions of increased dust content, which was previously impossible.

Operating modes of the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm electric manual fan:

• Mode I — pure ventilation
• Mode II — filter ventilation
• Mode III — regeneration

Additional information about the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan:

A feature and advantage of the fan with electric drive is that the gearbox is constantly connected to the impeller shaft and does not require additional actions to connect the motor shaft to the gearbox when switching to manual mode. In the absence of electricity, the fan operates by turning the gearbox handle manually.

Advantages of ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm (analogue of ERV-49):

The first models of electric manual fans for shelters were introduced as early as 1949. However, the ERV-49 model became morally and technically outdated: the fan was heavy, with low efficiency, high physical effort in manual mode, fixed direction of rotation, and an unchangeable casing rotation angle, which made operation and installation much more difficult.

Most importantly: the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan does not require additional coupling of the gearbox and electric motor — to switch to manual mode, it is enough to simply connect the handle. Another undeniable advantage is the fan power: it is twice as high as the ERV-49, allowing one person to ventilate much larger rooms manually.

Purpose of ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm:

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

Design of the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm electric manual fan:

The design of the ERV 2022-46 #4 w/motor AIR 100 L6 2.2 kW 1000 rpm fan consists of a strong structural steel housing, frame, special gearbox, and electric motor. The fan can operate both from an electric motor and manually by turning the gearbox handle.

The motor is constantly connected to the gearbox and does not require additional couplings. When the motor is turned off, ventilation is carried out manually — by turning the handle.

The fan is made with left-hand rotation. Usually, the fan is installed at a height of 1125 mm from the floor level to the motor axis.

The operation of the ERV-2022 electric manual fan is possible in the following modes:

• I — pure ventilation
• II — filter ventilation
• III — regeneration
