Gas Powered Air Compressors

Compact Gas-Driven Rotary Screw Air Compressor for Service Trucks and Mobile Mechanics

VMAC G30 gas powered air compressors are designed for fleet managers, service truck operators, mobile mechanics, tire service technicians, and light-duty contractors who need compact, lightweight, continuous-duty compressed air.

The G30 delivers 30 CFM at 100 psi, uses a Honda GX390 engine, weighs approximately 205 lb, and is built with VMAC’s patented rotary screw technology for reliable mobile air performance.

Applications

The VMAC G30 is ideal for:

Light and medium-duty mobile mechanics
Mobile tire service technicians
Light-duty contractors
Construction service vehicles
Municipal fleet service trucks
Agriculture and equipment repair vehicles
Utility service trucks

Commonly used tools:

The G30 is commonly used with:

3/4-inch impact wrenches
Up to 1-inch impact wrench with a small air receiver tank
Backfill tampers
2-inch horizontal grinders
Chipping hammers
Die grinders
Tire inflation tools
Air wands and 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. This helps operators complete jobs faster without waiting for air recovery.

60% Lighter

At approximately 205 lb, the VMAC G30 is up to 60% lighter than typical 22 to 30 CFM reciprocating gas engine driven air compressors with a 30-gallon air receiver tank. This helps fleets preserve payload, carry more tools, and reduce unnecessary truck weight.

50% Smaller

The G30 is more than 50% smaller than many competitive models, helping operators save valuable space on service trucks.

Industry-Leading Reliability

The G30 is available with an optional factory-installed cold climate kit. Honda engines include a 3-year warranty, and VMAC rotary screw air compressors include VMAC’s Lifetime Warranty (Limited).

FAQs for VMAC G30 Standard Gas Powered Air Compressors

Why do operators switch from reciprocating compressors to the VMAC G30 rotary screw air compressor?

Many operators switch from reciprocating compressors to the VMAC G30 because the G30 provides continuous airflow with no waiting for pressure recovery. Rotary screw air compressors also reduce truck weight, save cargo space, operate more quietly, and improve productivity for mobile mechanics, tire service technicians, and service truck operators.

When should a cold climate kit be added to a VMAC G30 air compressor?

A cold climate kit is recommended for operators working regularly in freezing or sub-freezing temperatures, especially in mountain regions, mining operations, utility fleets, and outdoor service truck applications. The cold climate kit helps improve cold-weather starting, oil temperature management, and overall winter reliability.

What does an FRL do on a mobile air compressor system?

An FRL, or Filter Regulator Lubricator, helps clean and regulate compressed air before it reaches pneumatic tools. On a mobile compressor system like the VMAC G30, an FRL helps reduce moisture, protect tools, improve air quality, and extend pneumatic tool life.

When should an air receiver tank be added to a VMAC G30?

An air receiver tank may be added to a VMAC G30 when operators use tools with sudden high air demand, operate in hot climates or at higher elevation, run larger impact tools, or are see excessive moisture in the compressed air. While the G30’s rotary screw compressor delivers continuous airflow, receiver tanks can help stabilize pressure in certain high-demand applications.

What industries commonly use the VMAC G30 gas powered air compressor?

The VMAC G30 is commonly used in mobile mechanic service, tire service, municipal fleets, utility service trucks, agriculture repair, equipment maintenance, light construction, and mobile repair applications where compact continuous-duty compressed air is required.

Why is the VMAC G30 popular for service trucks?

The VMAC G30 is popular for service trucks because it combines 30 CFM rotary screw performance, lightweight design, compact dimensions, Honda GX390 reliability, and 100% duty cycle airflow in a package designed specifically for mobile applications.

What is the difference between the G30 Standard and G30 Stacked?

Both systems deliver 30 CFM at 100 psi, but the G30 Standard uses a horizontal layout while the G30 Stacked uses a vertical footprint for truck bodies or commercial vans where deck and cargo space is limited.

What is the difference between the G30 and G30+GEN?

The G30 provides mobile compressed air. The G30+GEN combines compressed air with 3,600 W continuous AC generator power, making it a better fit for crews that need both air and electrical power.
