Vacuum units Avs , AVL and type pumps NVZ Designed for pumping air, non-aggressive gases and steam-gas mixtures from hermetic vacuum systems.
Units are economical and widely used in various industries: machine -building, metallurgical, electrical, electronic, in the production of food products, microbiological drugs, drugs and in other industries. Units are used to create a preliminary vacuum in high -bus drive installations.
Vacuum units AVL are most effective: for drying electrical products, in the production of building materials, in drying and evaporal installations.
Units of the AVZ and pumps type NVZ can operate at an environmental temperature from plus 10 ° C to 35 ° C.
Units of the AVPL -25 , 2 AVL -30 , AVPL -90 t and AVL -180 t can work under canopy at a temperature of minus 5 ° C to 35 ° C.
Units Avs -20 d , AVL -25 and 2 < 2 < /Strong> AVL -30 have air cooling, the remaining units are water.
Units 2 AVL -30 , AVL -90 t , AVPL -180 t have a filter built-in oil tank to clean the output of oil fog.
Unit 2 AVL -30 has a lubricant system that allows you to work in a wide range of input pressures.
Unit AVL -380 has a lubricant system that excludes polluted working fluids in the bearings.
The AVL -380 unit is designed to replace the HB3-300 pump. Units AVL -25 and 2 AVL -30 designed to replace the unit Avs -20 d in industries that do not require a deep vacuum.
