Airtech dry rotary vane pumps are oil-free vacuum/pressure pumps designed for industrial applications where compact equipment layout, clean operation, and reduced oil-related maintenance are important selection factors.
The dry rotary vane pump series supports both vacuum and pressure applications, making it suitable for systems that require air movement, holding, handling, conveying, or process support without the use of oil-sealed rotary vane pump technology.
The Airtech dry rotary vane pump family includes models ranging from fractional horsepower units to larger configurations for higher-capacity requirements.
Models include KRX-1, KRF-08, KRF-15, KRF-25, KRF-40, KRX-7A, KRF-70, KRF-110, and KRA-10DP with capacities from 5.5 to 150 CFM and horsepower ratings from 0.25 to 10 HP. Airtech also identifies the ORION series as capable of vacuum and pressure operation with published range values of 27″ Hg end vacuum and pressure to 14 PSIG.
These dry rotary vane vacuum/pressure pumps are designed with built-in particulate filters and silencers, helping simplify system integration while supporting quiet operation. Their compact, lightweight construction allows them to be considered for installations where space, equipment access, and serviceability are important.
The dry, oil-free design also makes the series an alternative to standard oil-sealed rotary vane pumps in applications where oil management, oil carryover concerns, or oil-related maintenance are not preferred.
