Rotary Screw Air Compressors

G Series Rotary Screw Air Compressor


Introducing the redesigned G Series rotary screw air compressors. A 15% smaller footprint and new front-loading fork lift slots make these rugged air compressors more versatile and easier to install.

The G Series features an innovative reduced-component, rugged, and integrated design centred around reliable delivery, durability and efficiency.

The G Series is engineered with steel tubes and a redesigned air end discharge hose with a dual flange-mounted, stainless-steel, braided flexi-hose for increased ruggedness and durability.

The new and enhanced inverter is equipped with EMC filters and a DC choke, providing improved harmonic performance.

The G Series is robust, yet quiet and compact – an air system engineered for efficiency & reliable performance – providing high-capacity air delivery and stable system pressure with minimal installation space.

These heavy-duty, high-performance & premium-efficiency rotary screw air compressors operate at a 100% duty cycle in variable or fixed speed and are ideal for continuous or intermittent-use applications requiring 82 to 116 SCFM of compressed air at 120 psi.

G Series Rotary Screw Air Compressor

Fixed Speed, Belt Drive

Ideal for continuous-use applications with constant compressed air demand. Demonstrating efficient power transmission from the motor to the air end, the fixed-speed, belt-drive provides maximum flexibility in pressure selection and features a single-point belt-tensioning system

Variable Speed, Belt Drive

The VSD constantly aligns energy use with air demand, adjusting motor speed to provide optimum performance and reliability, resulting in a compressor that is extremely economical and energy efficient, providing energy savings of up to 25%.

Solid & Silent

Engineered to effectively minimize noise levels: Designed with solid steel base frames and floors, powder-coated, heavy gauge, acoustically insulated steel cabinets and sound attenuating foam barriers with an oil resistant coating.

Engineered For Efficiency

The simplified, reduced-component, encapsulated design of the airend enhances reliability and contributes to silent & efficient operation. The high-efficiency industrial electric TEAO motor maintains constant motor-efficiency and offers a wide operating range with exceptional full/part load performance.


The G Series AirSystem offers a complete solution for your entire compressed air system requirements, providing clean, dry, compressed air. The G Series AirSystem includes:

  • Microprocessor controlled ASD100 ProDry Refrigerated Air Dryer with Stainless Steel Separator & Auto Drain.
  • DF-Series Pre-Filter Canister with 1-Micron Filter Element Cartridge.
  • 120 Gallon Air Receiver – Built to ASME Codes & CRN Registered.
  • Air Compressor

A unique compressed air system configuration developed by DV Systems. It delivers clean, dry compressed air continuously, consistently and directly to the air receiver by employing the combination of a filter and dryer.

This configuration ensures that the tank is virtually dry, achieving not only an unprecedented level in the abatement of corrosion, but also maximizes the capacity of the tank for its intended use – to store and provide continuously cool, clean and dry air for your required applications, reliably and consistently.

Integrated Air After-Cooler & Oil Cooler

The overall unique, integrated system design & comprehensive cooling configuration, including a dual-function air after-cooler and oil cooler, contributes to the production of discharge air temperatures as low as 15 degrees above ambient – reducing energy consumed by air dryers, promoting system reliability and extending the air-receiver’s life.

DV Systems Remote Start
Remote Start Kit: Part #DSC-00285

You can control and monitor the compressor from anywhere in your shop with the rugged DV remote panel. Easily see that the compressor is turned on or if there is service required with large, bright indicator lights. The keyed switch ensures safety and a secure control of when the compressor is turned on. The Durable polycarbonate enclosure is water and dust proof.

DV Systems Auto-Drain-Electronic-KK-9860
Electronic Zero Loss Auto Drain: Part #KK-9860

An electronic drain ensures that any potential condensate is discharged from the air receiver tank regularly, optimizing system performance.
