Compressors do just what there name says they compress the refrigerant to change it’s state from a low temperature gas to a high temperature gas so it can expel heat into an area where it is desirable.

Primarily failure is caused through lack of lubrication, it is important to ensure that oil levels are kept topped up and that the compressor is used regularly throughout the year.

The compressor squeezes the air that enters it into smaller areas, resulting in an increase in the air pressure. The Compressor is the most important piece of a heating or cooling system, which located in the outdoor unit, the compressor is responsible for pumping refrigerant throughout the system. The compressor is often called "the heart of the system" because it pumps the refrigerant from the indoor evaporator to the outdoor

All Touaregs sold in the US include at least one air compressor. For Touaregs without the air suspension, the air compressor is located in the back of the car, near the spare tire. For Touaregs with the air suspension, the air compressor is part of the su spension system and has an accessible outlet under the front passenger's seat.

No, each AirPen is calibrated individually to the specific air pump which comes with that particular pen. Normally, you cannot turn a large compressor down to 4psi and still get a consistent, non-sputtering flow.

Yes. A typical unit/compressor loses 2%-4% efficiency per year. Compress Shield will help maintain the system’s peak efficiency and its lubrication properties will reduce wear and tear, hence increasing the life of the unit/compressor. Older units tend to have oil built up within the system that robs them of efficiency. Compress Shield eliminates that in old systems and prevents it from developing in new systems.

The more air you have the better. But it really depends on the level of work you plan to do. If you just want to make a few repairs to a fender/door and other touchup work, a small 20 gallon compressor would suffice. But it likely won't be able to keep up if you're painting an entire vehicle and you may have to stop and let it catch up periodically (which can result in paint problems). Remember, a compressor also needs a cool-down period (Duty-cycle).

Zanfel works safely into the dermal layer of your skin, binds to the urushiol oil, and, when rinsed off, takes the oil with it down the drain.
