Most airless spray equipment uses a high pressure paint hose between the airless pump and the airless spray gun, excluding handheld airless paint sprayers which naturally do not use high pressure airless paint hose.
Excluding budget orientated DIY airless spray pump units which are often supplied with 25 feet or 7.5 m of airless paint spray hose the most common length found fitted standard to airless paint sprayers is 50 feet or 15 m in length. The most common internal diameter airless paint spray hose is 1/4 inch or 6 mm ID.
Airless spray painting would be among the most popular methods used by professional painting contractors these days. Unlike conventional compressed air spray painting an airless spray gun has no compressed air involved in the atomisation of paint. A small airless spray tip restricts the flow of paint from the airless spray pump and as this high pressure flow of paint passes through the airless spray tip the paint is atomised into spray as the stream of paint strikes the atmosphere.
A most common cause of airless spray gun problems and early failure are a result of incorrect cleaning and airless paint sprayer storage procedures.
When your airless paint spray job has completed the first step is to recover as much of the remaining paint that still remains in the airless spray unit. Consult your airless paint sprayer operation manual for the recommended procedure to remove any remaining paint from the airless machine and to properly flush the airless unit out.
