Mobile Air Compressors for Sale

Mobile air compressors are engine-driven units built for transport on service trucks, skid frames, and tow-behind trailers, delivering compressed air at job sites, along pipelines, and wherever fixed power is unavailable. CompressorPros carries mobile compressors from 30 to 800 CFM in gasoline and diesel configurations. All orders ship free.

What Are Mobile Air Compressors?

A mobile air compressor is an engine-driven unit designed to travel to the work rather than stay in a fixed location. Unlike shop compressors that plug into wall power, mobile compressors carry their own gasoline or diesel engine and mount on a skid, truck bed, or trailer for transport. They deliver critical compressed air and serve construction crews, utility contractors, pipeline operations, mobile mechanics, and service fleets that need reliable compressed air at locations without electrical infrastructure.

Skid Mount vs. Vehicle Mount vs. Towable

Mobile compressors are available in three mounting configurations, and the right one depends on how the unit will travel to the job.

Skid-Mounted Air Compressors

Skid-mounted air compressors sit on a flat steel frame designed to be loaded onto a truck bed, flatbed trailer, or equipment platform using a forklift, crane, or hoist. The skid stays with the compressor and provides a stable operating base on site. Skid mount is the most versatile configuration because the unit can ride on different vehicles as needed. The ConX SC70 Compact 70 CFM Engine Driven Rotary Screw Air Compressor is a compact air compressor that fits easily on a standard truck bed.

Vehicle-Mounted Air Compressors

Vehicle-mounted air compressors are designed for permanent or semi-permanent installation on a service truck. These use a two stage piston pump or rotary screw airend driven by a gasoline engine and mount directly to the truck bed alongside tool boxes and equipment. Service truck compressors are the standard for mobile mechanics, utility repair crews, and fleet maintenance operations. The ABAC ABC13-30GH 13 HP Honda Two Stage 30 Gallon Service Truck Air Compressor is one of the most-searched service truck compressors on the site.

Towable Air Compressors

Towable air compressors mount on a single-axle or dual-axle trailer with a tow hitch, allowing them to be pulled directly behind a truck to the job site. Towable units are the standard for construction, road work, sandblasting, and pipeline operations where the compressor needs to move independently of the work vehicle. The Elgi D185T4F is a heavy-duty towable option for high-CFM field applications.

Gasoline vs. Diesel

Gasoline Mobile Compressors

Gas-powered mobile compressors use Honda, Kohler, or similar commercial engines and are common in two configurations: rotary screw units up to about 70-80 CFM, and service truck piston compressors in the 9-14 HP range. Gas engines cost less upfront and are easier to fuel in the field. They are well-suited to shorter run times and lighter-duty applications.

Diesel Mobile Compressors

Diesel mobile compressors use Kubota, Kohler, or similar industrial diesel engines and are the standard for sustained, all-day operation at 90 CFM and above. Diesel engines deliver better fuel economy under continuous loads, longer engine life, and greater durability. The Elgi D185T4f-SKID represents the diesel advantage at the 185 CFM level. For jobs that run 6-10+ hours a day, diesel is the practical choice.

Key Specifications

CFM (Cubic Feet per Minute): Mobile compressors range from about 30 CFM for small service truck units to 290+ CFM for large diesel tow-behind systems. Match CFM to the combined demand of all tools running simultaneously on site.
HP (Horsepower): Ranges from 9 HP for service truck piston compressors to 75+ HP for industrial diesel rotary screw units. Engine HP directly determines CFM output.
Engine Type: Honda or Kohler for gasoline; Kubota or Kohler for diesel. All are commercial-grade engines rated for continuous field operation.
Max PSI (Pounds per Square Inch): Most mobile compressors deliver 100-150 PSI. Some gas rotary screw models offer a 150 PSI option for sandblasting and high-pressure tool applications.
Fuel Type: Gasoline for units up to about 90 CFM and service truck compressors. Diesel for 90 CFM and above.
Weight: Ranges from under 500 pounds for compact gas skid mounts to over 3,000 pounds for large diesel tow-behind units. Verify your truck bed load rating or towing capacity before purchasing.

FAQ

What is the difference between a mobile compressor and a portable compressor? A portable compressor is a wheeled unit you roll between work areas, typically electric, with a 8-30 gallon tank. A mobile compressor is an engine-driven unit mounted on a skid, truck bed, or trailer, designed to travel by vehicle to job sites without electrical power. Mobile units deliver significantly higher CFM.

What is the most common mistake when buying a mobile air compressor? Not matching the mounting configuration to your transport method. If you have a service truck, choose a vehicle-mounted or skid-mounted unit. If the compressor needs to travel independently, choose a towable unit. Buying a heavy skid mount without verifying your truck bed's load capacity can create safety and logistics problems.

Should I choose gasoline or diesel for a mobile compressor? For intermittent use and shorter run times, gasoline is less expensive upfront and easier to fuel. For all-day, continuous operation (6+ hours), diesel delivers better fuel economy, longer engine life, and greater durability under sustained loads.

How much CFM do I need for sandblasting? Most sandblasting nozzles require 100-185 CFM depending on nozzle size. A 1/4" nozzle draws roughly 100 CFM; a 3/8" nozzle draws 150-185 CFM. Choose a mobile compressor rated at least 20% above your nozzle's CFM requirement.

Do mobile compressors require special maintenance? Follow the engine manufacturer's schedule for oil, filter, and coolant service (typically every 250-500 hours). The rotary screw airend requires oil and filter changes every 1,000-2,000 hours. Service truck piston compressors follow standard reciprocating maintenance intervals. Check air filters, belts, and fluid levels daily before operation.
