Rotary screw compressors - Gardner Denver PureAir T
The oil-free standard for processes where air purity is critical.
The Gardner Denver PureAir T is an ISO 8573-1 Class 0 (2010) certified oil-free two-stage fixed speed rotary screw air compressor, available from 75 to 450 HP (55 to 355 kW), delivering up to 1,916 ACFM at 115 PSIG with noise levels as low as 75 dB(A). Sold and serviced in Quebec by Aircom Technologies, authorized Gardner Denver distributor since 1999.
Class 0 oil-free air: Zero risk of contamination
The PureAir T delivers guaranteed 100% oil-free compressed air, certified ISO 8573-1 Class 0, the strictest purity class of the standard. No oil is injected into the compression chamber, so the compressor cannot introduce oil into your process, your product or your production environment.
Built to withstand 24/7 operation under demanding conditions, the PureAir T is the fixed speed choice for plants with steady air demand in pharmaceuticals, food and beverage, electronics and other regulated environments.
For variable or fluctuating demand, see the PureAir TVS variable speed model.
Why Choose the PureAir T Over a Lubricated Compressor?
Because it removes the risk of oil contamination at the source instead of relying on filtration.
A lubricated compressor injects oil into the compression chamber, then depends on downstream filters to capture oil aerosols, so air quality is only as reliable as filter maintenance. With the PureAir T, oil never enters the air stream.
- Class 0 certified: no oil added by the compressor
- Simplified air treatment: no oil-removal stage to maintain
- Process protection: reduced risk of batch rejection
- Compliance: meets the strictest purity class of ISO 8573-1

GD RotorArmor™: Built for Lasting Airend Efficiency
The airend rotors and housings are protected by GD RotorArmor™, a coating that creates both a chemical and a mechanical bond with the metal. According to Gardner Denver, some manufacturers use a soft PTFE-graphite top layer that seals well at first but wears quickly, reducing performance by 10% or more. RotorArmor is designed to maintain efficiency throughout the life of the compressor.
- Stainless steel 2nd stage rotors for corrosion protection
- Motor-driven oil pump lubricating the gears from start-up to complete stop
- Closed-loop water/glycol jacket cooling on 90 to 355 kW models, about 3% more efficient than oil-in-jacket cooling

FAQ: Gardner Denver PureAir T
Why is ISO 8573-1 Class 0 certification essential?
Class 0 is the strictest air purity class of ISO 8573-1: the compressor adds no oil to the compressed air. In pharmaceutical, food and electronics production, it protects product integrity.
What is the performance range of the PureAir T?
12 models from 55 to 355 kW (75 to 450 HP), at 100, 115 or 145 PSIG, delivering about 296 to 1,916 ACFM (8.3 to 53.6 m³/min).
What is the difference between the PureAir T and the PureAir TVS?
The PureAir T runs at a constant speed for steady demand. The PureAir TVS adjusts its speed to actual consumption, reducing energy costs when demand fluctuates.
