ARTICULATED PISTON - Rugged, long life design for highest pressure and air flow capabilities; oil-less; industrial duty design with full pressure restart capabilities.

WOB-L® PISTON - Lightweight WOB-L® piston design results in quiet and efficient performance at high pressure and vacuum levels as well as high flows; oil-less; WOB-L® piston provides long life and the most economical performance

ROTARY - Highest air flow to physical size ratio of any Thomas design; oil-less; pulsation free air delivery; simple design with few moving parts provides long service-free life.

DIAPHRAGM - High efficiency in medium pressure and vacuum ranges; oil-less; compatible with aggressive flow media; can be staged for higher vacuum levels; fluid capability with smaller models.

VIBRATING LINEAR - For high flow - lower pressure or vacuum applications requiring quiet, very long life, and low power consumption; smaller units with DC drives.

LIQUID - For fluid pump applications: peristaltic pumps, diaphragm fluid pumps, rotary vane fluid pumps, oscillating piston fluid pumps and linear diaphragm fluid pumps

Radial Blowers - For pressure and vacuum operation

Side-Channel blowers - For pressure and vacuum operation

Dry running - "Rotary vane", "Claw" &  "Screw" style vacuum pumps / compressors

Oil lubricated - Vacuum pumps

Roots blowers - For pressure and vacuum operation

Air-Centers - (Air Supply)
