appropriate accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with
vacuum pump oil.The pump can be operated singly.
It also can be as a backing pump when combined with another high vacuum pump, such as diffusion pump, oil
booster vacuum pump and roots vacuum pump. Rotary piston vacuum pump can be used for a longer time than
the sliding vane rotary vacuum pump.
