Their products are trusted to operate in critical applications, due to their advanced performance and durability.  To virtually eliminate downtime, they’re also designed for ease of serviceability and many are equipped with dual-voltage motors – making them the most versatile products in the pneumatic industry.

Industry leading and innovative technologies

Air and Motor Technology

Gast rotary vane air motors use compressed air to produce rotational motion of a shaft.  Rotary vane air motors have axial vanes fitted into a slotted rotor, which mounts eccentric with the bore of the motor’s housing. The vanes extend to seal against the housing bore using springs, cam action, or air pressure, depending on the motor design. Torque develops from the pressure of the compressed air acting on one side of the vanes causing the rotor to spin.

Compressors and Vacuum Pumps

Gast offers a complete line of air-moving products in a broad range of types and sizes for pressure and vacuum generation.

Tank Systems

Tank systems are designed to make small pumps do big jobs and are a natural extension of Gast and Jun-Air lines. Utilizing either the Piston or Rocking Piston compressor technologies, these systems can be designed work with a range of tank sizes to meet the needs of your specific applications. Included in our Gast line are tank systems specifically designed for dry sprinkler applications. The Jun-Air line of clean and quiet compressors are the perfect choice for a range of medical, dental, and laboratory applications and are backed by a two-year warranty.

GAST Product Ranges

Rotary Vane Compressors and Vacuum Pumps

• Pulse-free air delivery
• Oilless or lubricated models
• Low vibration
• Extra quiet AT Series
• Long, service-free life
Electric motors are dual frequency, multi-voltage AC for worldwide applications.
A complete line of accessories available
Pressure: 15 psig – 1.0 bar
Vacuum: 28 “Hg – 65 mbar
Air Flow: 55CFM – 93.5m³/H

Do you know how they work?

Sliding, flat vanes in an eccentric-mounted rotor are flung outward against the bore of the pump to generate pressure and vacuum in a rotary vane pump.

Rocking Piston Compressors and Vacuum Pumps

• Oilless
• Rugged construction
• Quiet operation
• Dual frequency motors
•Corrosion resistant models, tank models, and a complete line of
recommended accessories available

Pressure: 175 psig – 12 bar
Vacuum: 29 “Hg – 65 mbar
Air Flow: 12CFM – 18.7m³/H

Do you know how they work?

In a reciprocating motion, a flexible cup mounted on top of the connecting rod creates vacuum or pressure as the cup maintains a seal against the cylinder walls in a rocking motion

Air Motors and Gear Motors

• Available in lubricated or non-lubricated models
• Variable speed
• Non-electrical sparking
• Cool running
• Compact and portable
• Operate in all positions
• Mounting flexibility- hub, foot, face, NEMA C-Flange, or Metric D Series interface mountings and clockwise, counter-clockwise, or reversible rotations

Air Motor: 9 HP – 7.1 kW
Variable Speeds: 10,000 RPM
Gear Motor Max Torque: 5,200 lb. in. – 587 Nm

Do you know how they work?

Compressed air into an air motor forces the sliding vanes out of the eccentric-mounted rotor. An extended shaft on the rotor spins to perform the work.

Diaphragm Compressors and Vacuum Pumps

4 – 24 volt DC options on the
miniature styles
Pressure: 60 psi – 4.2 bar
Vacuum: 29 “Hg – 31 mbar
Air Flow: 3.8 CFM – 6.5m³/H

Do you know how they work?

In reciprocating motion, with a short stroke, the diaphragm at the top of the
connecting rod flexes up and down in a closed chamber, creating pressure or vacuum.

Piston Compressors and Vacuum Pumps

• Oilless
• Rugged construction
• Long, service-free life
• Corrosion resistant
• Motor-mounted or separate drive styles

• A complete line of recommended
accessories also available
Pressure: 125 psi – 8.8 bar
Vacuum: 28.5 “Hg – 48 mbar
Air Flow: 11 CFM – 18.7m³/H

Do you know how they work?

In reciprocating motion, with a short stroke, the diaphragm at the top of the connecting rod flexes up and down in a closed chamber, creating pressure or vacuum.

Air Flow: 1350 CFM – 2294m³/H

Do you know how they work?

A certain amount of air slips past each impeller blade during rotation and
returns to the base of a succeeding blade for reacceleration – “regenerative.”
