Specific environment and choice
Co-D version: When your use environment has mild corrosive gas, such as acidic, strong oxidizing and other environments, you can choose the Co-D version of the vacuum pump. By increasing the coating of the part of the pump body that contacts the pumped gas, The reliability of the pump body in the environment. (It is recommended to choose Impal S series oil-free screw vacuum pump for strong corrosive environment)

H2O-D version: H2O-D version vacuum pump can be selected in chemical experiments, freeze-drying, medical and other environments with more water vapor. Impulse can solve the condensation and retention of water vapor by increasing gas input and using specific vacuum pump oil. The reliability of the vacuum pump.

EP-D version: explosion-proof, used in flammable and explosive environments, and can be equipped with explosion-proof vacuum pump accessories and body to meet the vacuum requirements in explosion-proof environments.
