Shipping Air Compressors Freight Class Guide
Air Compressors typically classify around Class 70, in the 12-18 lb/ft³ density range. Shop and industrial air compressors.

Measure the full footprint including packaging, and include pallet weight in your total. Carriers will re-measure at the terminal.
Shipping Air Compressors the Right Way
Gauges and Fittings Are the Fragile Point
An air compressor's tank and housing are rugged, but the pressure gauges, valves, and fittings that stick out from the unit are comparatively fragile, so crating needs to protect those specific points rather than just wrapping the whole unit generically.
Pressure Connections Need Secure Protection
Fittings and connection points on an air compressor can crack or bend under impact even when the tank itself is undamaged, so crates should cap or cushion exposed connections separately from the general packaging around the unit.
Crate Construction Should Match Unit Weight
Larger industrial air compressors are heavy enough that crates built for lighter shop equipment will not hold up, so crate strength should be matched to the specific unit's weight rather than using a one size fits all crating approach.
Air Compressors: What Carriers and Shippers Look For
Shop and industrial air compressors combine a metal tank, motor, and pump assembly into a moderately dense crated package, landing them in a similar freight class range to other mid weight industrial equipment. The main shipping concern is protecting gauges, fittings, and pressure connections from impact damage, since these smaller components are far more fragile than the compressor's rugged tank and housing suggest.
Why Air Compressors Classify Around Class 70
Shop and industrial air compressors typically run 12 to 18 pounds per cubic foot once crated, which puts most shipments in the Class 70 range under the standard density table. That density reflects a metal tank, motor, and pump assembly combined with a fair amount of void space around the unit's irregular shape once it's properly crated and cushioned for transit.
Crating and Fitting Protection Tips
Pressure gauges, valves, and hose connections should be individually protected within the crate, since these smaller components are much more prone to damage than the compressor's tank or housing. A crate that wraps the whole unit generically without specific attention to these fragile points is more likely to generate a claim, even if the tank itself arrives undamaged.
Crate strength should scale with the compressor's actual weight, since a crate built for a small shop compressor will not adequately support a larger industrial unit. Shippers who move a range of compressor sizes should adjust crating specifications by unit rather than using one standard crate design across the whole product line.
Equipment and Handling Notes
Dry van is standard for air compressor freight, and no temperature control is needed under normal shipping conditions. Drivers should handle compressor crates carefully during loading and unloading, since the exposed fittings and gauges are more vulnerable to impact damage from forklift contact than the unit's main housing would suggest.
Common Shipping Mistakes
The most common mistake is crating an air compressor without specific protection for its gauges and fittings, which leads to damage claims on components that are cheap to protect but expensive to replace or repair. The second is using an undersized crate for a heavier industrial unit, which risks the crate failing under the compressor's weight during handling or transit.

Carriers Hauling Air Compressors
“Compressor crates look solid until you notice a gauge sticking out unprotected. I always check for that before I load anything on top nearby.”
“The bigger compressors need real crate strength. I've seen a lighter crate flex under a heavy unit and that's not something you want to discover mid route.”
