Getter-ion exhaust carts PVIG-250/630-9-019
Getter-ion exhaust carts PVIG-250/630-9-019 are used for oil-free extraction of gases and gas mixtures (air) from vacuum systems and for creation of deep and superdeep vacuum. Getter-ion exhaust carts PVIG-250/630-9-019 are used as a part of vacuum processing equipment.
Operation of exhaust carts PVIG-100/160-9-018 is based on the principle of gas absorption by sprayed getter and the ability of Penning discharge cell to extract gases. In order to increase gas (including inert gases) extraction speed, the cart combines evaporation and ion units in the common casing.
The exhaust carts are supplied in a moderately cold climate modification category 4 according to GOST 15150. Getter-ion exhaust carts PVIG-250/630-9-019 are powered by special power supply units, not included in the delivery package of the pump.
Exhaust carts PVIG-250/630-9-019 are produced in two modifications of the connecting flange to the pump body: according to OST 11 868.007 (FO) and according to GOST 26526 (FG).
