Dry Screw Vacuum Pumps

Dry Screw Pumps are available for most high vacuum applications and are an ideal alternative to liquid ring and rotary vane pumps. Due to their dry operation, screw pumps are particularly suitable in wet and dusty applications that are the cause of high running costs of traditional pumps. The Dynavac range is extensive with capacities of up to 3000 m³/h .

Through puts of up to 3000 m³/h can be achieved with vacuum levels of down to 0.05 mbar
