Double-rotor vacuum unit AVD-50/10

Dvuhrotor vacuum unit AVD-50/10 is designed for pumping out of hermetic vessels with pressure not more than 106,7 kPa (800 mm Hg.) air, non-aggressive to the working fluid and construction materials fire-explosion-proof and non-toxic gases, vapours and vapour-gas mixtures, cleaned from dripping moisture and mechanical contaminants, with oxygen content not more than in air (21% by volume) under normal conditions, from 106,7 kPa (800 mm Hg) to the residual limit. Double-rotor vacuum unit AVD-50/10 can be used as a pre-deflation unit for high-vacuum pumps. Type of climatic execution UHL4, the unit is not intended for pumping air, vapours and vapour-gas mixtures from one volume to another, it is not intended for operation in fire-explosive production.
