  • Light/medium duty mobile mechanics
  • Mobile tire service technicians
  • Light duty contractors

Commonly used tools:

  • 3/4” impact wrenches
    • Up to 1″ impact wrench with a small air receiver tank
  • Backfill tampers
  • 2” Horizontal grinders
  • Chipping hammers
  • Die grinders
  • Tire inflation
  • Air wands/blow guns


30 CFM. 100% of the Time.

VMAC G30 gas powered air compressors include a patented 30 CFM rotary screw air compressor designed to produce full air power, 100% of the time, so you don’t need an air receiver tank. Get jobs done faster, without interruption.

61% Smaller

The VMAC G30 was mindfully designed with one goal: to easily fit in modern service trucks. The newest G30 is stacked vertically, which significantly reduces the amount of vehicle space it requires, allowing it to fit either in the rear service body compartment or in the bed of a pickup truck. With a footprint of just 2.5 square feet, the stacked G30 is 61% smaller than competitive models.

59% Lighter

VMAC G30 gas powered air compressors are engineered and manufactured for mobile applications. Weighing less than 210 lb, the VMAC G30 is up to 59% lighter than typical 22 – 30 CFM reciprocating gas engine driven air compressors with a 30-gallon air receiver tank. Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your truck, carry more materials, or save money with better fuel economy.

Industry-leading Reliability

VMAC G30 gas powered air compressors are proven to work in extreme cold climates across North America when ordered with an optional, factory-installed cold climate kit. Engines supplied by Honda come with an industry-leading 3-year warranty and VMAC rotary screw air compressors come with the industry’s first Lifetime Limited Warranty. For peace of mind, without the headache.
