How Much Does a Portable Diesel Air Compressor Cost?
Used portable diesel air compressors typically cost $4,000 to $9,000, with larger or low-hour machines reaching about $12,000.
Towable diesel compressors are the backbone of outdoor and remote work where grid power is not an option. Output in cfm is the main price driver, followed by engine hours and overall chassis condition. The figures below reflect inspected, road-ready used units from brands like Atlas Copco, Ingersoll Rand, Doosan, and Sullair.
Price by type
| Type | Typical price | Notes |
|---|---|---|
| 185 cfm towable | $4,000–$7,000 | The most common size — runs one or two breakers or a sandblast pot. |
| 250-375 cfm towable | $6,000–$8,500 | Mid-range output for larger tool banks and line work. |
| 400 cfm towable | $7,000–$9,000 | Heavy output for demanding blasting, drilling, or multi-tool crews. |
| Large or low-hour units (up to 450+ cfm) | $9,000–$12,000 | Late-model or low-hour machines with premium condition. |
What affects the price
Air output (cfm)
The headline spec. Each step up in cfm meaningfully raises price, which is why most buyers size carefully.
Engine hours
Diesel hours track value closely. High-hour units can still serve for years once the engine and air-end check out.
Emissions tier
Tier 4 Final machines can carry a premium over older tiers, especially where emissions rules apply to the work site.
Chassis and trailer condition
Running gear, tires, lights, and brakes affect both price and whether the unit is ready to tow away.
Brand
Atlas Copco XAS and Ingersoll Rand portables hold strong resale thanks to parts availability and field reputation.
Bottom line
A 185 cfm towable in the $4,000 to $7,000 band covers the majority of job-site needs, while serious blasting or drilling crews step up to 400 cfm. Match cfm to your heaviest simultaneous load before you shop on price. We quote current inventory with hours and condition disclosed.

How many cfm does a jackhammer need?
A typical pneumatic breaker draws roughly 90 to 100 cfm, so a 185 cfm compressor comfortably runs one heavy breaker or two smaller tools at once.
Can I tow a portable compressor behind a pickup?
Most 185 cfm units are light enough for a half-ton truck with the right hitch rating. Larger 400 cfm machines are heavier, so confirm the gross trailer weight against your tow vehicle.
What hours are too many on a diesel compressor?
There is no hard cutoff. A well-maintained unit can run well past 10,000 hours. What matters most is a sound air-end and a clean service history, both of which we verify.
