Custom Rotary Screw Compressor solutions for your Industrial Engine

OEM Custom Solutions

Does your job require more compressed air than your current compressor can handle?

If you answered yes, then VMAC may have an option for you. Most industrial engines have a factory option for a reciprocating compressor that was designed for intermittent duty air brake applications. For industries like dust collecting, spray foam applicators, prime assist water pumps, road patching and air arc welding, a more robust and higher performing compressor is required. VMAC offers continuous duty rotary screw compressors ranging from 20-150 CFM for the following engines. Don’t see an application for your engine? Contact us.

  • Air Brakes
    Better suited for high-duty cycle usage, VMAC offers a rotary screw air compressor solution for your demanding air brake needs.
  • Spray Foam
    Portable, lightweight spray foam systems air available for many applications. Adding an onboard air compressor rather than towing one to the job site reduces the need for another vehicle or a second trip.
  • Pothole / crack sealing
    Turn your pothole/crack sealing trailer into an all-in-one package. Adding an air compressor to your existing engine provides your customer with added value and reduces the need for additional pieces of equipment.
  • Air arc gouging
    When the job calls for structural steel welding and other rugged outdoor work, you need an engine-driven welder that covers all your process needs – stick, MIG, TIG, flux-cored and gouging – and also meets the latest diesel fuel emissions standards. Upgraded for Tier 4 Final (T4F) compliance, the Air Vantage series has been re-engineered to deliver smoother arc characteristics and improved pipe welding capabilities. The Air Vantage® 600 SD includes a VMAC belt-driven compressor with separate gauges to monitor compressor hours and pressure.
  • Air tools
    Sometimes you just need air to power traditional air tools, blow off your equipment or fill a tire. Give yourself that option by including a rotary screw air compressor with your equipment or machine.
  • Railway Maintenance
    Railway maintenance is tough enough without having to manage more and more pieces of equipment. Use an existing unit to power your air compressor by adding a rotary screw compressor system to it.
  • Compressed air foam firefighting
    Mobile compressed air foam fire-fighting requires vehicles that can quickly reach the scene. Adding a light-weight, powerful rotary screw compressor to your CAF system’s engine provides a compact unit ready to go when you are.
  • Compressor / Generator
    Many applications have a diesel engine driven generator supplying power to their equipment, while at the same time supplying power to run an electrically driven air compressor, on the same application. Instead of powering the electric motor driven compressor with the generator, why not use the diesel engine to power both the generator and the air compressor at the same time and save a step. One driver instead of two.
