Always choose a compressor with a bit more than you need. The most important factor is the volume of air that you will be using and at what pressure FAD CFM. Please read our guide here or give us a call. Work out the CFM (FAD) figure your most powerful tool needs to operate and then choose a compressor will at least that rating.

There will always be a certain amount of oil carry over from a compressor. When the compressor it is running hot or is being over worked, oil carry over is made worst. The hot oil fumes and then condenses in the hose and in the tools. The affect can be reduced by running the compressor as cool as possible, making sure there are no leaks and that the outlet pressure regulator on the compressor is set as low as possible. Ensure there there is plenty of ventilation. You can place a cooling fan near the unit it in hot weather. A coalescing filter can also be used to reduce oil and condensate.

The Air Receiver size you will use will depend on the amount of air that you need stored. A benefit to a larger Air Receiver, for air compressors is that the motor will not start and stop as often as a smaller Air Receiver. However, if you do not believe that you will use a good amount of air, it may be smarter and cheaper to use a smaller Air Receiver.
