The 5 Horsepower GC190 Honda built engine features an OHC (Overhead Cam) / OHV (Overhead Valve) assembly that provides a smoother engine operation, easier starting, low emissions and low fuel consumption.

The Honda engine also provides a high torque ratio across its wide RPM range that reduces engine speed reduction from sudden high loads. The uncomplicated build of the engine is another bonus as it reduces the need for excessive maintenance and servicing.

The noise level (89 Db) is average for a gas powered air compressor. Although, the machine is designed to be run outdoors and/or in remote areas the noise issue shouldn’t present much of a problem.


The low maintenance pump delivers 5.0 SCFM @ 90 PSI and 6.9 SCFM @ 40 PSI with a maximum pressure of 155 Psi, which is enough to run several low pressure air tools at the same time.

The pump is also oil free which means less maintenance for the user. When you combine that with the direct drive system and the two piece cooling system you have a winning combination that will deliver the goods time after time.

Build & Design

The design of the Industrial Air Contractor CTA5090412 is excellent. The motor and pump Portable Gas Contractor Compressorassembly sit in between the two pontoon style tanks which makes the whole construction very sturdy. The under frame of the compressor is manufactured from a square tubular steel and has four rubber feet that reduces vibration, stops noise and also prevents the machine from jumping around on the floor.

If you consider the machine is made from mainly steel and not plastic, has a 4 gallon storage capacity and also includes a gasoline engine then the weight to output ratio is excellent.

The whole design has been very well thought out and the light weight and small size (H 20” x W 21.5” x D 24.5”) makes the air compressor easy to lift, transport and store in small areas.


The controls are fairly typical for this type of portable compressor, they include:

Pressure Relief Valve which will open if the engine does not switch to idle when the pressure Industrial Air Contractor CTA5090412 Controlsreaches the factory set level. This valve can be checked by pulling on the ring connected to the valve.

Regulated pressure gauge that displays the outlet pressure to the air tool in use.

This Industrial Air Contractor CTA5090412 Review would not be complete without mentioning the cons of the compressor.


  • Price – Yes, it is on the expensive side, but you do get what you pay for and for a quality contractor grade compressor such as this you have to expect to pay slightly more.
  • Compressor is louder (89 Db) than the electric machines – If you want the power and portability of a gas powered compressor then there are some tradeoffs, one of them being slightly more noise.
  • No wheels – If you find that the machine is too heavy to carry around you can always buy a Dolly or Cart from Amazon to take the load.
