Industrial Air 6.5 HP 4-Gallon 155 PSI Kohler Gas-Powered Oil-Free Portable Air Compressor
Product Overview
The Industrial Air Contractor CTA6590412 is a compact, gasoline-powered air compressor designed for contractors who need dependable compressed air at jobsites without access to electrical power. It combines a 6.5 HP Kohler gas engine, 4-gallon twin-tank receiver, and oil-free direct-drive pump in a portable pontoon-style package.
With a 155 PSI maximum pressure and approximately 5 CFM at 90 PSI, this compressor is well suited to intermittent-duty pneumatic applications such as framing, roofing, fastening, inflation, and general jobsite tasks.
Key Features
- 6.5 HP Kohler gasoline engine for portable, cord-free operation.
- 4-gallon twin-tank configuration with two 2-gallon steel tanks.
- 155 PSI maximum pressure.
- Oil-free, direct-drive pump requires less routine maintenance.
- 6.9 CFM at 40 PSI and approximately 5 CFM at 90 PSI.
- Pontoon-style design provides balanced portability.
- Four vibration isolators help minimize movement during operation.
- Integrated control panel with regulator and pressure gauges.
- Push-to-connect quick coupler for convenient tool connection.
- Pressure-relief valve for system protection.
- Compact footprint for transportation and storage.
- Designed for construction, roofing, framing, and general contracting applications.
Kohler Gas Engine
The compressor is powered by a 6.5 HP Kohler SH270 OHV gasoline engine. The gasoline-powered configuration allows the unit to operate independently of an electrical outlet, making it particularly useful on construction sites and other locations where utility power is unavailable.
Sources for this model differ slightly on the published engine displacement, listing approximately 196cc or 212cc. For that reason, the engine's displacement is best verified from the specific unit's engine identification label rather than treated as a fixed specification.
Oil-Free Direct-Drive Pump
One of the compressor's main advantages is its oil-free direct-drive pump. Because the pump does not require routine pump-oil changes, maintenance is simpler than with a conventional oil-lubricated compressor.
The direct-drive design connects the engine directly to the pump, while a two-piece cooling system is designed to improve airflow and help reduce operating temperatures.
4-Gallon Twin-Tank Configuration
Instead of using one conventional receiver, the compressor uses two 2-gallon steel tanks, providing a combined capacity of 4 gallons.
The pontoon-style arrangement keeps the tanks positioned side-by-side, helping create a balanced package that is easier to handle around a jobsite.
The 4-gallon capacity should be viewed as stored-air capacity, not the compressor's air-delivery rating. For tool compatibility, always compare the tool's SCFM requirement with the compressor's CFM output at the applicable pressure.
155 PSI Maximum Pressure
The compressor has a 155 PSI maximum pressure rating, providing sufficient pressure for many common pneumatic tools.
Its published air-delivery figures are:
- 6.9 CFM at 40 PSI
- 5 CFM at 90 PSI
This makes it particularly appropriate for intermittent-use tools such as nailers and staplers rather than high-consumption pneumatic equipment requiring large volumes of air continuously.
Integrated Control Panel
The integrated control panel provides convenient access to the compressor's operating controls. It includes:
- Quick-set pressure regulator
- Tank pressure gauge
- Tool pressure gauge
- Push-to-connect quick coupler
- Pressure-relief valve
This arrangement allows the operator to monitor tank pressure and adjust the regulated pressure supplied to the connected pneumatic tool.
Jobsite-Friendly Portable Design
The compressor weighs approximately 75 lb. and uses a compact horizontal configuration with cushioned handle grips. Its pontoon-style tank arrangement is designed for balanced handling, while four vibration isolators help control vibration and prevent the unit from "walking" during operation.
Unlike a wheeled wheelbarrow compressor, this particular model is generally classified as a hand-carried portable compressor.

Recommended Applications
Framing
The approximately 5 CFM output at 90 PSI makes the compressor suitable for compatible framing nailers and other intermittent fastening tools.
Roofing
Its portable gas-powered design allows contractors to use compatible pneumatic roofing equipment where electrical power is unavailable.
Remodeling
The compact size makes it convenient for moving between different work areas.
General Construction
Useful for pneumatic nailers, staplers, inflation equipment, blow-off tasks, and other tools within its air-delivery capacity.
Maintenance and Service
Suitable for lighter-duty pneumatic applications where portability is more important than continuous high-volume airflow.
What Makes This Compressor Different?
The combination of a gasoline engine and oil-free direct-drive pump gives this compressor a useful balance of mobility and low maintenance.
The gasoline engine removes the need for an electrical connection, while the oil-free pump eliminates routine compressor-oil maintenance. The result is a compact compressor intended for contractors who prioritize straightforward operation and easy transportation.
Maintenance
Although the pump itself is oil-free, the gasoline engine still requires normal engine maintenance.
Recommended practices include:
- Check engine oil before operation.
- Follow the Kohler engine's recommended oil-change schedule.
- Keep the engine air filter clean.
- Inspect fuel lines and connections.
- Check hoses and fittings for leaks.
- Drain receiver condensate as required.
- Inspect the coupler and pressure gauges.
- Keep cooling surfaces free of dirt and debris.
- Inspect vibration isolators for wear.
- Follow the manufacturer's service schedule.
Important Operating Consideration
Because this compressor is gasoline powered, do not operate it inside enclosed buildings, garages, trailers, or other poorly ventilated spaces. Gasoline engine exhaust can contain dangerous carbon monoxide.
Use the compressor outdoors and follow all manufacturer safety instructions.
