Product Information
Full details
The SIP PX3/150-SRB is a robust, oil-lubricated, belt-driven air compressor engineered for professional tradespeople and intensive workshop environments. It delivers consistent, high-volume air power through a powerful 3Hp motor and a 150-litre receiver, making it ideal for tasks requiring sustained pneumatic tool operation. While its heavy-duty build ensures longevity, its substantial footprint and weight mean it is best suited for permanent or semi-permanent installation rather than mobile job-site use.

FAQs
What type of oil does this compressor use?
You should use a high-quality, dedicated reciprocating compressor oil. Consult your manual for the specific viscosity grade recommended by SIP.
Can this unit be used for professional spray painting?
Yes, the 16Cfm displacement is suitable for spray guns, though you should always use an additional filter-regulator and water trap to ensure dry, oil-free air.
Does it require a special electrical socket?
The unit is designed for a standard 230V supply, but ensure your workshop circuit is rated appropriately for the 3Hp motor starting current.
How often should I change the oil?
As a general rule for heavy-duty trade use, perform an oil change every 250 to 500 operating hours, or at least once annually.
Is the compressor portable?
Due to its weight and 150-litre tank size, it is designed for static installation in a workshop rather than frequent transport.
What is the maximum pressure?
The compressor has a maximum working pressure of 145Psi (10 Bar).
Troubleshooting
Compressor failing to start
Check the mains connection, ensure the pressure switch is set to the ON position, and verify the thermal overload button has not popped out.
Excessive moisture in air lines
Drain the air receiver fully, verify the location of your water trap, and ensure the ambient temperature in the workspace isn't causing rapid condensation.
Pressure build-up is slow
Check for air leaks at joints using a soapy water solution, and inspect the belt for signs of wear or improper tension.
Pros and Cons
Pros
- High displacement of 16Cfm for demanding tools
- Italian-manufactured build quality
- Excellent heat dissipation from the multi-finned flywheel
- Durable cast iron barrel construction
- Generous 150-litre capacity for steady air flow
Cons
- Heavy unit requiring stable, flat flooring
- Requires a 230V power supply
- Oil-lubricated design necessitates regular maintenance
- Large footprint may be difficult for small workshops
Setup, Compatibility & Care
To ensure optimal performance, install the compressor on a perfectly level, solid concrete surface to minimize vibration wear. Since this is an oil-lubricated model, check the oil sight glass before every use and top up with recommended compressor oil if the level is low. The unit requires a standard 230V mains connection; ensure the circuit can handle the load of a 3Hp motor to prevent tripping breakers. Regularly drain the 150-litre receiver via the drain valve at the bottom of the tank to remove accumulated condensation, which prevents internal corrosion. Inspect the drive belt tension periodically to ensure it is not slipping, and keep the external cooling fins free from dust and debris to maintain heat dissipation efficiency.
