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.

Going over a surface immediately after airless spray painting with a paint roller is referred to as back rolling. There are a few reasons why back rolling with a paint roller is required in certain applications.

Air assisted airless spray painting, as the name implies, is airless spray, assisted with compressed air atomisation. This mix of paint atomising technologies enables faster application rates than is possible with conventional or HVLP spray painting while achieving transfer efficiencies that rival, or some even argue, betters transfer efficiencies of HVLP spray painting equipment.

Storing an airless spray machine.

After completely cleaning your airless spray machine as described in this post it is time to prepare the airless spray unit for storage, especially if it may not be used for some time.
