Multistage Dry Vacuum Pump Gas Way	Screw dry vacuum pump Gas Way
Airflow direction radial, Corrosive process gas does not attack the bearing and gear axially direct	Airflow direction axial, Corrosive process attack the bearing and gear axially in gear cap violent
Process gas is compressed uniformly in each stage of rotors. Uniform compression heat, so lower exhaust gas temperature	The process gas is compressed centrally at the end of screw, so high exhaust gas temperature and screw
Process gas could contact with more cooling jacket surface, high heat dissipation efficiency	Process gas could contact with few cooling jacket surface, low heat dissipation
Roots rotor is more resistant to particles and adherents, few impacts on its performance after its surface wear and corrosion	Screw rotor is unsuitable for particles and adherents, large impacts on its performance after its surface wear and corrosion
