Thomas 688CHIQQ22-232 Oil-Less WOB-L Piston Vacuum Pump

The Thomas 688CHIQQ22-232 Oil-Less WOB-L piston vacuum pump is an oil-free, continuous-duty compressor/vacuum unit that delivers up to 100 PSI of pressure or 26.3 inHg of vacuum for contamination-sensitive applications. It runs from a 220–240 VAC power supply (50 Hz) or 230 VAC (60 Hz) using a permanent split capacitor (PSC) motor, drawing about 0.70 A and roughly 140 W at 1,410 RPM. Constructed from corrosion-resistant aluminum with a long-life piston seal, it provides maintenance-free operation and is suited for medical analyzers, laboratory equipment, packaging and printing systems, environmental monitoring, vacuum clamping, and industrial OEM machinery. Maintenance technicians, OEM manufacturers, and system integrators use this pump for repairs, retrofits, and new system integration.
