40 CFM Hydraulic Air Compressors

VMAC’s 40 CFM hydraulic air compressor is the best choice for fleet managers and owners who require hydraulic powered compressed air and aren’t satisfied with the performance of reciprocating air compressors.

The powerful H40 rotary screw air compressor is ideal for operating small to medium sized air tools. Meanwhile, the compact design allows it to fit on trucks and specialty equipment with limited available space.


Common jobs that use the compressor system:
  • Mobile heavy duty mechanics
  • Mobile tire service technicians
  • 24/7 roadside repair technicians
  • Light to medium duty lube trucks

Commonly used tools:

  • 3/4” impact wrenches
  • Light chipping hammers
  • Die grinders
  • Tire inflation

H40 Hydraulic Air Compressors Benefits

Free Up To 6 Cubic Feet

VMAC’s 40 CFM hydraulic air compressors free up to 6 cubic feet on the truck deck. Systems are designed and engineered to be compact for service trucks and applications where space is limited.

Decrease Truck GVW By Up To 260 lb

H40 air compressors reduce truck GVW by as much as 260 lb, due to the systems’ innovative design, lightweight materials, and integrated components. Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your truck, carry more materials, or take advantage of better fuel economy.

Up To 40 CFM, 100% Of The Time

VMAC hydraulic 40 CFM air compressors use patented rotary screw technology that can operate intermittently for smaller jobs, but are designed to run at 100% duty cycle without stopping, so operators don’t have to wait for their air compressor to fill up a bulky air receiver tank. This maximizes tool performance and eliminates downtime by keeping operators working.
