What is good quality compressed air for a lubricated air motor???

• Clean (free of dirt, debris, pipe scale and other foreign matter)
• Dry (no condensable water)
• Lubricated (1 drop of oil for every 50 CFM of air while the unit is running, or 1 drop of oil per continuous minute of run time)
  • Gast recommends Gast #AD220 oil or a detergent SAE#10 automotive engine oil for lubricating.

How does a Gast Rotary Vane Air Motor Operate?

• Rotary vane air motors operate with compressed air and do not require electrical power. Expanding air behind the vanes produce rotation, providing horsepower and torque.

Challenges with Lubricated Air Motors:

While Gast Lubricated Air Motors are rugged and reliable when provided with good quality, lubricated air, the associated in-line lubricators and the oil itself pose maintenance and application challenges.

• Oil must be added and maintained
  • This maintenance can be time consuming
  • It may be logistically challenging
  • It may be remote
  • Maintenance downtime can be costly

• Oil itself may not be compatible or allowed in some applications.
  • Mixing, processing and pumping applications where potential oil contamination of high value materials and liquids is not acceptable.
  • Items for consumption, such as food, beverage and pharmaceuticals are other areas where oil contamination is simply not allowed.

The SOLUTION:

Gast’s  “LubeFree” and MVP line of air motors feature LubeFree vanes made of a proprietary material that works effectively without lubrication.

• Independent testing has shown operation in excess of 10,000 hours in completely oilless applications!
  • Lubricating these air motors will extend their life even further.
• Gast’s LubeFree Series of air motors are based on the popular lubricated 2AM & 4AM Series of air motors to allow for drop in versatility.
  • In addition to the new LubeFree vanes these units incorporate surface treatment help minimize corrosion.
    • “LL” option has a rotor with corrosion treatment for applications with limited or no lubrication.
    • “NLP” option with complete corrosion protection to the rotor, body and endplates.

GAST MVP Series Air Motors

•  Gast’s MVP Series of Air Motors also feature Gast’s LubeFree vanes, but are available in both Aluminum and Stainless Steel .
  • Optional 300 Series Stainless Steel available with IP ratings
• Multiple mounting options include NEMA, IEC flange, hub and foot supports.
