Airless Paint Spray Safely

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.

Use Airless Spray Safely

Airless spray gun safety.

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.

Diaphragm Airless Valve Checks

Diagnosing problems with valves in hydraulic diaphragm airless paint sprayers.

Hydraulic diaphragm airless paint spray machines are usually fairly basic simple machines with not much to go wrong. Unlike piston airless paint sprayers the valve action in diaphragm airless sprayers is much more passive and susceptible to problems that may not ordinarily affect piston pump.

A piston airless paint spray may effectively continue to operate using only one of the two valves commonly found in piston airless paint sprayers and enable the operator to complete a job.
