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.
How many times have you gone to your local airless spray outlet to pick up an airless spray tip for a specific airless spray job and the airless tip size you need is not in stock? You may even end up phoning or travelling around several other outlets who stock airless spray tips and still not find the airless tip you need.
These days there are many places online where you can order brand-name quality airless spray tips and have the airless tip delivered for $20 to $25.
Purchasing the correct airless spray paint equipment can be the difference between a successful airless spray painting job or spending the time you would have spent spray painting trying to complete the spray paint job with an inferior piece of airless spray equipment.
Tailing when spraying with an airless paint sprayer is a phenomena where two distinct heavier lines of paint appear on either edge of the paint spray pattern. Inside these heavier edge lines there may be no paint or very little paint before the spray pattern reappears and often becomes heavier towards the center.
Tailing with airless paint sprayers can be the result of several different factors or a combination of factors.
Serious injury can occur if an airless spray unit is not used correctly.
Even small handheld DIY airless spray guns reach pressures which can cause serious fluid injection injury. Never place any part of the body near nozzles or remove guards.
Always ensure that all components of your airless spray machine including airless paint spray hose, spray gun and airless spray tip are rated to a working pressure that exceeds the output of your airless spray pump.
Apart for regular cleaning, lubricating, correct storage, and minor adjustment procedures, all of which can be carried out by owner operators of an airless spray machine, there is not usually any manufactuer issued servicing schedules for airless spray pumps that require regular "service" visits to a airless spray service centre.
