Gardner Denver Rotary Screw Compressors

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.

Gardner Denver offers a standard 2-year package warranty on most models. The Platinum 10-Year Extended Warranty covers airend parts for 10 years and major components for 5 years. The Platinum+ Full Package Warranty adds a 5-year renewable service agreement through factory-trained distributors, covering wear items and package components for comprehensive long-term protection.
