Two-rotor Vacuum Unit AVD-50/5 for Air Extraction from Sealed Containers

Dvuhrotor vacuum unit AVD-50/5 is designed for pumping out of hermetic vessels with pressure of 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 atmospheric pressure to the maximum residual pressure. Also the twin-rotor vacuum unit AVD-50/5 can be used as a pre-deflation unit for high-vacuum pumps. Type of climatic execution UHL4 and O4, the unit is not designed for operation in fire-explosive production.
