Call for Special Pricing

The Davey Air Compressor is built to run for decades. The compressors are built around a unique central idea, The Perma-Vane® air end design, a concept unparalleled for rugged dependability. The entire Davey line of field-proven rotary sliding vane compressors offers this long outstanding list of standard features, all combined to bring optimal performance.

. High Capacity Cylindrical Roller Bearings. No Adjustment needed ever!
. Minimum B-10 bearing life of 90,000 hours.
. Patented Perma-Vane® blade design for extended life in the most hostile environments.
. Unique Free Floating Rotor and Blade design.
. Fewer moving parts. Fewer parts to fail. Fewer parts to replace.
. Air end is completely field serviceable.
. 5 Year or 15,000 hour air end warranty*.
. Two-stage 10 micron filtration is standard.
. Large capacity oil sump for superior oil/air separation and longer lubricant life.
. Simple, reliable, low maintenance electro-pneumatic controls.
. Belt Driven - Uses standard motors with no expensive gearboxes needed.
. Low RPM - Less wear, less noise.
. Package is designed for high ambient temperature conditions.
. Easy access to all filters through full sized doors.
. Liquid filled pressure gauges for accurate readings.
. Compact design requires very little floor space.
. Automatic dual control. Saves energy automatically. When air demand is met, the compressor unloads itself. After a short interval, it shuts itself off automatically. When air demand returns, the compressor automatically goes back to full load.
. Entire unit is completely field serviceable.

The Perma-Vane® Air End Principle
The difference is the Davey Air End with its patented Perma-Vane® design and its overall simplicity. The Perma-Vane® Air End has surprisingly few moving parts. That means fewer parts to fail and fewer parts to replace. They breakdown less because there is less to breakdown. Because of the unique Davey floating rotor and blade principle, the Perma-Vane® Air End actually "fine-tunes" itself as it operates, which eliminates the risk of failure due to loss of clearance. Most screw compressor air ends begin to wear out the day they are turned on. But as the Perma-Vane® Air End ages, its efficiency actually improves. The more the air end works, the better it gets!
