AVM structure
The units are distinguished by their compactness, high operational reliability, ease of maintenance and repair, and minimal cost.
— The use of reversible fans allowed to implement an effective and extremely simple design of the fan unit which can be used as a stationary main ventilation, as well as an auxiliary, temporary, or mobile unit
— As a result of special aerodynamic design, the static pressure loss in the flow area of the rotary flap elbow of the flow switch, which contains a vane system for flow equalization, is minimized
— Elements of each fan unit are mounted on a common frame, which provides increased reliability of the "motor-fan" system
— The combined output part of the unit guarantees "non-freezing" at sub-zero temperatures
— Special cladding of the inner surface of the volute chambers and/or the outlet part of the unit ensures effective noise suppression
