Key Features
- Rotary vane pump design for low vibration and consistent performance
- Dual-function capability—operates as both compressor and vacuum pump
- Oil-free or self-lubricating operation for clean air handling
- Compact, portable construction for bench-top or mobile deployment
- Dry-running mechanism suitable for continuous operation
- Standard motor options for 115V or custom voltage configurations
Technical Specifications
Specific rated flow rates, maximum pressure, and vacuum ratings are subject to motor configuration and duty cycle. For exact performance data including CFM, PSI, and vacuum depth, consult the factory datasheet or contact your distributor with the model and motor serial number.
Typical Applications
- Laboratory and analytical equipment air supply
- Medical device vacuum systems
- Printing and packaging machinery
- Environmental test chambers
- Pneumatic tool operation and tire inflation
- Equipment deaeration and fluid transfer
Compatibility & Replacements
Compatible With
- Standard 1/2″ NPT inlet and outlet ports (verify with your system)
- 115 VAC single-phase motors (standard configuration)
- Industrial vacuum and pressure systems with RA-series compatibility
- OEM equipment originally equipped with Thomas rotary vane pumps
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The RA-75-4HB is part of the Thomas RA series of rotary vane pumps; cross-compatibility with other models requires matching motor voltage, displacement, and port configuration.
Works With
- Pneumatic tools and regulators with standard NPT connections
- Vacuum filtration and collection systems
- Pressure relief valves and safety switches
