How to Ship a Towable Air Compressor: Trailer Types, Permits, and Preparation

Types of Air Compressors and Their Transport Requirements

Air compressors span a wide range of sizes and configurations, each with different transport requirements:

Compressor Type	Typical Weight	Transport Method	Permit Needed?
Small towable (up to 185 CFM)	2,000–5,000 lbs	Tow behind pickup or flatbed	Usually no
Mid-size towable (185–375 CFM)	5,000–12,000 lbs	Flatbed or step-deck trailer	Usually no
Large towable (375–900 CFM)	12,000–25,000 lbs	Flatbed or step-deck trailer	Possibly (check width)
Large stationary/skid-mounted	25,000–80,000+ lbs	Flatbed, step-deck, or lowboy	Yes if oversize/overweight
Industrial rotary screw (trailer-mounted)	15,000–40,000 lbs	Step-deck or lowboy	Check dimensions

Hazardous Materials Considerations

Air compressors are classified as hazardous freight due to their fuel and oil content. Most carriers require:

• Fuel tank drained or nearly empty: Carriers typically require fuel tanks to be drained to prevent leaks during transit. Some allow a small residual amount (1/4 tank or less) if the fuel valve is shut off and the unit is secured upright.
• Oil check: Ensure oil is at proper level and not leaking. Compressors must be transported upright — laying them on their side can cause oil to migrate into valves and air intake, causing serious engine damage.
• Battery disconnect: Many carriers require the battery to be disconnected to prevent accidental starting during transit.
• Pressure relief: The air tank must be fully depressurized before loading.

Trailer Selection for Air Compressor Transport

The right trailer depends on the compressor's size, weight, and whether it's towable or skid-mounted:

• Flatbed trailers: Suitable for most mid-size towable compressors. Standard flatbeds handle up to 48,000 lbs and accommodate widths up to 8.5 ft without permits. The compressor is loaded via forklift or crane and secured with chains and binders.
• Step-deck (drop-deck) trailers: Preferred for taller compressors that would exceed height limits on a standard flatbed. The lower deck height provides additional clearance for tall units.
• Lowboy trailers: Used for very heavy industrial compressors (50,000+ lbs) or units with extreme height that require the lowest possible deck.
• RGN trailers: Occasionally used for very large skid-mounted compressors that can be driven or rolled onto the trailer.

Loading and Securing Air Compressors

Proper loading and securement is critical for safe transport:

1. Use appropriate lifting equipment: Forklifts work for most towable units. Large industrial compressors may require a crane. Never attempt to load a heavy compressor without proper equipment.
2. Secure upright: Compressors must remain upright during transit. Use heavy-duty chains, binders, and straps rated for the load weight.
3. Protect vulnerable components: Wrap gauges, pressure switches, and regulators in foam or moving blankets to prevent vibration damage.
4. Chock wheels: For towable units, chock the wheels to prevent rolling on the trailer deck.
5. Verify tie-down points: Use the manufacturer's designated tie-down points. Chaining to plumbing, hoses, or delicate components can cause damage.

Permit Requirements for Large Compressors

Most towable compressors fall within legal dimensions and don't require oversize permits. However, large industrial units may trigger permit requirements:

• Width over 8.5 ft: Requires oversize permit in all states. Some large trailer-mounted compressors exceed this threshold.
• Height over 13.5 ft: Requires oversize permit and bridge clearance verification.
• Weight over 80,000 lbs GVW: Requires overweight permit. Large industrial compressors on heavy trailers can approach or exceed this threshold.

Cost Factors for Air Compressor Transport

Shipping costs for air compressors vary widely based on size and distance:

• Small towable units (up to 185 CFM): $400–$1,200 for regional moves (under 500 miles)
• Mid-size towable units (185–375 CFM): $800–$2,500 for regional moves
• Large industrial compressors: $2,000–$6,000+ depending on size, weight, and permit requirements
• Liftgate service: Add $150–$300 if the delivery site lacks a forklift or loading dock
