Rotary screw air compressor - PureAir TVS
14% more efficient than the competition. Proven. Certified. Oil-free.
The Gardner Denver PureAir TVS is an ISO 8573-1 Class 0 (2010) certified oil-free two-stage variable speed rotary screw air compressor, available from 125 to 476 HP (90 to 355 kW), delivering up to 1,809 ACFM at 100 PSIG with noise levels as low as 62 dB(A). Up to 14% more efficient than leading competitors, it can save $50,000 or more in energy costs over five years. Distributed exclusively in Eastern Canada by Aircom Technologies, authorized Gardner Denver partner since 1999.
Up to 25% energy savings. No compromise on air purity.
The Gardner Denver PureAir TVS combines guaranteed 100% oil-free compressed air (ISO Class Zero) with the energy efficiency of a fully integrated variable speed drive — delivering precisely the volume of air your process demands, at all times, without waste.
Where the fixed-speed PureAir T excels in constant-demand applications, the PureAir TVS is engineered for facilities with variable or fluctuating air demand. The integrated VSD continuously adjusts motor speed to match actual air consumption, eliminating the energy losses associated with load/unload cycling and delivering a stable supply pressure across the full operating range.
For facilities in Québec, Ontario, and Atlantic Canada requiring certified oil-free air with variable demand management from 125 to 476 HP, the PureAir TVS is the high-efficiency solution — supported locally by Aircom Technologies, your authorized Gardner Denver distributor for Eastern Canada since 1999.
Variable Speed vs. Fixed Speed: The Energy Argument
Energy represents the largest cost component in a compressor's lifetime — typically over 80% of total ownership cost for a fixed-speed unit operating at 70% load. A variable speed compressor operating at the same load reduces the energy share to approximately 58% of total cost, generating energy savings of up to 25% — and in the case of the PureAir TVS, up to 14% higher efficiency than the leading competitor, translating to $50,000 or more in documented energy savings over five years in a typical application.
- Up to 25% energy savings versus fixed-speed operation at partial load
- Up to 14% higher efficiency than comparable variable speed oil-free competitors
- Stable delivery pressure across the full capacity range, no pressure swings
- Wide turndown range for maximum flexibility across varying production demands
- Reduced wear: no repeated load/unload stress on mechanical components
GD RotorArmor and integrated drive: the complete technical package
The PureAir TVS is built on the same proven airend architecture as the PureAir T, enhanced with a fully integrated variable speed drive for maximum part-load efficiency. All airend rotors and housings are coated with GD RotorArmor, a high-performance dual chemical and mechanical bond that maintains peak compression efficiency throughout the service life of the machine, unlike soft PTFE-graphite competitor coatings that degrade by 10% or more within a few years.
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 efficiency
- Motor-driven oil pump providing pre-rotation lubrication and maintaining oil pressure through complete shutdown
- Motor-driven closed-loop water/glycol cooling through airend jackets, delivering 3% better efficiency than oil-in-jacket systems
GD governor touchscreen controller
Every PureAir TVS includes the GD Governor, a standard 10-inch full-color touchscreen controller designed for precision compressor management and real-time diagnostics:
- Full-color schematics and machine status at a glance
- Advanced monitoring with data logging capability
- iConn remote monitoring connection for proactive maintenance planning
- Sequencing of up to 4 compressors

FAQ: Gardner Denver PureAir TVS
What is the difference between the PureAir T and the PureAir TVS?
The PureAir T excels in constant-demand applications, whereas the PureAir TVS is engineered for facilities with variable or fluctuating air demand. Its integrated Variable Speed Drive (VSD) continuously adjusts the motor speed to match actual air consumption, eliminating the energy losses associated with traditional load/unload cycles.
How much energy can I save with a PureAir TVS compressor?
The PureAir TVS is up to 14% more efficient than leading competitors. By matching output to demand, it can generate energy savings of up to 25% compared to fixed-speed units operating at partial load—representing potential savings of $50,000 or more over a five-year period.
Is the PureAir TVS certified for oil-free operation?
Yes. It is ISO Class Zero certified, guaranteeing 100% oil-free compressed air. This is a critical requirement for pharmaceutical, food and beverage, and electronics industries in Quebec, Ontario, and Atlantic Canada to prevent product contamination.
