Gardner Denver Rotary Screw Compressors

Oil-flooded compressors inject lubricant into the compression chamber for cooling and sealing, making them cost-effective for general industrial use. Oil-free models like the EnviroAire and PureAir series produce ISO 8573-1 CLASS 0 certified air with zero oil carryover, essential for food, pharmaceutical, and electronics applications where contamination is unacceptable.

Gardner Denver rotary screw compressors span from 5 HP (L Series) up to 400+ HP (LRS Series, Electra Saver G2), with the EnviroAire T/TVS reaching 422 HP. This broad range accommodates small workshops, mid-size manufacturing plants, and large-scale continuous industrial operations requiring consistent high-volume compressed air.

Variable speed drive technology adjusts motor speed to match real-time air demand rather than running at a fixed speed. The LRS Series achieves 30–50% energy savings, and the EnviroAire TVS delivers up to 35% direct savings. This is especially effective in facilities where air demand fluctuates between 40–75% of full load capacity throughout the day.

Gardner Denver's patented TurnValve technology varies the active compression volume within the airend to precisely match output to demand without changing motor speed. It achieves 60–100% energy efficiency in the partial load range where most industrial systems operate, avoiding the efficiency losses typical of inlet valve modulation on conventional fixed-speed compressors.

The EnviroAire T/TVS, PureAir T/TVS, and EnviroAire TVS 45 kW models are independently certified to ISO 8573-1 CLASS 0, the most stringent oil-free air quality standard. They are also cULus listed, CSA approved, and comply with ASME/CRN coded pressure vessel requirements, meeting safety and quality standards for North American industrial and regulated industries.

iConn is a factory-installed or optional module that connects the compressor to a secure remote monitoring platform. It provides real-time operational data, diagnostic alerts, and performance reporting accessible via web browser. This allows facility managers and service teams to proactively identify issues, schedule maintenance, and avoid unplanned downtime without requiring an on-site visit.

For these contamination-sensitive industries, Gardner Denver offers ISO CLASS 0 certified oil-free and silicone-free models such as the EnviroAire T & TVS, PureAir T/TVS, EnviroAire TVS 45 kW, and Ultima series. These deliver guaranteed 100% oil-free compressed air that prevents product contamination in processing, packaging, and cleanroom environments, meeting strict purity requirements for drug manufacturing and food-grade production lines.
