Rotary screw compressors - PureAir T
The oil-free standard that regulated industries trust.
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 125 to 450 HP (90 to 355 kW), delivering up to 1,916 ACFM at 100 PSIG with noise levels as low as 75 dB(A). Distributed exclusively in Eastern Canada by Aircom Technologies, authorized Gardner Denver partner since 1999.
Class 0 Oil-Free Air: Zero Risk of Contamination
When product purity is non-negotiable, the choice of compressor technology is not a preference, it is a compliance requirement. The Gardner Denver PureAir T delivers guaranteed 100% oil-free compressed air, certified ISO Class Zero, eliminating any risk of oil contamination in your process, your product, or your production environment.
Designed for 24/7 operation under extreme conditions, the PureAir T is the fixed-speed solution for industries where air quality directly affects product integrity: pharmaceuticals, food and beverage processing, electronics manufacturing, medical gas systems, and any regulated production environment.
For facilities in Québec, Ontario, and Atlantic Canada requiring certified oil-free compressed air from 125 to 450 HP, the PureAir T is the technically validated choice, supported locally by Aircom Technologies, your authorized Gardner Denver distributor for Eastern Canada since 1999.
Why Choose the PureAir T Over a Lubricated Compressor?
Lubricated compressors rely on downstream filtration to remove oil aerosols, a system that depends entirely on filter maintenance and replacement. The PureAir T eliminates the risk at the source. No oil injection into the compression chamber means no possibility of oil carry-over, regardless of filter condition. For regulated industries, this is the only technically defensible position.
- Class 0 certification: guaranteed zero oil content in delivered air
- No downstream oil filtration required: reduced maintenance complexity and cost
- Process protection: no risk of product contamination or batch rejection
- Regulatory compliance: meets the most stringent air quality standards in pharmaceutical and food processing
GD RotorArmor: Engineered for Maximum Airend Efficiency and Longevity
Not all oil-free compressors are built the same. The critical differentiator in the PureAir T is the GD RotorArmor coating applied to all airend rotors and housings, a high-performance dual chemical and mechanical bond engineered to maintain efficiency and extend airend life under continuous cycling.
Competing manufacturers apply soft PTFE-graphite coatings that seal well initially but wear rapidly, reducing compressor performance by 10% or more within a few years of operation. GD RotorArmor maintains maximum efficiency throughout the full compressor service life.
Both fixed and variable speed airends include:
- Stainless steel 2nd stage rotors for maximum corrosion protection
- GD RotorArmor coating on all rotors and housings for sustained performance
- Motor-driven oil pump providing lubrication prior to airend rotation and maintaining pressure until complete stop
- Motor-driven closed-loop water/glycol cooling circulating through airend jackets, providing 3% better efficiency than oil-in-jacket cooling
Standard Package Features
