PVR PVH Dry Screw Vacuum Pump With Adjustable Variable-Frequency Control Water Cooling
1. Product Overview
The AIRIPA PVR PVH Series Oil Free Dry Screw Vacuum Pump is a high-capacity industrial vacuum pumping unit featuring equal-diameter, variable-pitch screw technology and an optimized two-stage pumping configuration. Designed for clean, high-vacuum applications, it combines an oil-free pumping chamber with controlled gas compression and efficient vacuum generation.
The series includes nine listed model configurations, offering nominal pumping speeds from 600 to 7,200 m³/h and a specified ultimate pressure of ≤0.1 Pa.
With variable-frequency control, water cooling, nitrogen purge protection and an integrated enclosure, the PVR/PVH Series is suitable for demanding semiconductor, photovoltaic, lithium battery and industrial vacuum processing applications.
2. Key Features & Benefits
Optimized Two-Stage Pumping Design
A two-stage configuration provides a wider pumping range and supports stable vacuum performance under varying gas loads.
Equal-Diameter Variable-Pitch Rotors
Variable-pitch screw geometry provides progressive gas compression to support pumping efficiency and energy management.
Oil-Free Pumping Chamber
Dry screw technology eliminates oil injection into the pumping chamber, helping reduce process contamination risks.
High Pumping Capacity
Nominal pumping speeds from 600 to 7,200 m³/h accommodate large industrial vacuum systems and high gas-throughput requirements.
High Vacuum Performance
A specified ultimate pressure of ≤0.1 Pa supports processes requiring low operating pressures and clean vacuum conditions.
Variable-Frequency Control
Adjustable motor operation helps match pumping performance to changing process requirements.
Water Cooling and Nitrogen Protection
Water cooling supports temperature management, while nitrogen purge and sealing provisions help protect the pumping system.
Integrated Industrial Construction
The enclosed unit design supports equipment integration, installation and maintenance access.
3. Working Principle
The PVR/PVH Series uses synchronized, non-contacting screw rotors to transport gas through the pumping chambers. Its equal-diameter, variable-pitch geometry progressively compresses gas as it moves from the inlet toward the exhaust.
The optimized two-stage configuration combines pumping sections to increase overall gas-handling capacity and achieve lower pressures. Variable-frequency control adjusts operating speed, while water cooling and nitrogen purge systems support stable operation under suitable industrial process conditions.
