Product description

– The California Air Tools CAT-6310 ultra quiet and oil free 1.0 hp air compressor features a large 6.3 gallon steel air tank. The 6.3 capacity ensures that the unit has a lot of compressed air to keep your air powered tools running for long periods. The tank has a horizontal profile which enhances stability when in use even on uneven surfaces.

– This air compressor has an oil free dual pump with a life cycle of at least 3000 hours. The oil free operation allows you to work with the air compressor on any type of surface without having to worry about oil spills. Oil free operation also reduces maintenance costs you’d otherwise have to incur buying new replacement oil.

The pump is driven by a powerful 1.0 horsepower motor. At its peak, the motor is able to reach 2.0 hp for faster recovery and continuous supply of air to your air powered tools. The motor runs at an average 1680 RPM which is lower than most competing units. This low RPM allows the air compressor to operate quietly and remain cool for extended periods.

The motor features a low Amp draw of 8 Amps. This reduces chances of tripped circuit breakers and, protects the motor from sudden voltage drops.

– The California Air Tools CAT-6310 is rated at 120 PSI max. It can produce 2.35 CFM at 90 PSI and 3.80 CFM at 40 PSI. Its recovery time from empty to full tank is rated at 130 seconds meaning you’ll spend little time before being able to get started on your project.

This air compressor sits on a wheel kit. The wheels with rubber tires allow you to cart the air compressor along rather than lift it. The rubber tires also help to reduce vibrations as well as protect surfaces the compressor is placed upon. Easy transport is further enhanced by the light 49 lbs body.

– It comes fitted with a water trap which helps to draw away accumulated water from the air tank. A thermal overload protector also helps to keep the unit from damage due to overheating.
