The LA-250(R) nitrogen filling trap is installed on the inlet flange of the diffusion pump and is designed to reduce the flow of working fluid vapors into the pumped volume by condensing them on the elements of the freezing device cooled with liquid nitrogen.

The use of a 2VVN1-25(H) water-ring vacuum pump for pumping out water-gas mixtures is allowed only if the bulk of the water is separated and discharged at the pump entrance. Failure to comply with this requirement may lead to unacceptable overload of the electric motor and destruction of the working parts of the 2VVN1-25(H) pump. The 2VVN1-25(H) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) according to GOST standard 15150-69, meets the requirements of technical specifications TU 3648-015-00218526-2000, designed and manufactured taking into account the requirements of GOST R 52615-2006. The quality of electricity must meet the requrimemnts of GOST 32144-2013.

ConFlat (CF) standard connections are used to ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.

Size of Dn: 10,16,20,25,32,40,50.

The AVB-50 vacuum water ring unit consists of a 3BBH2-50 vacuum water ring pump and an EV-50 water ring vacuum ejector

The ISO-KF connection (DIN 28 403 and ISO 2861) allows quick installation and replacement of components in vacuum systems. The connection consists of two symmetrical ISO-KF flanges (1), a centering ring with an O-ring seal (2) and a quick-release clamp (3). High-vacuum ISO-KF connections can be mounted without using a tool by simply turning the nut of the quick-release clamp.

The AVD-150/63 unit consists of a series-connected two-rotor vacuum pump NVD-600 and a 2NVR-250D plate-rotary vacuum pump. The pumps are connected to each other by means of an adapter, which acts as both a pipeline and a support unit. The AVD-150/63 unit can operate continuously at an inlet pressure of no more than 133 Pa (1 mm Hg) or pumping out one or more sealed vessels with a total volume of 17.5 m3 from atmospheric to maximum residual pressure for 8 hours.
