Air Spray Gun Application Guide

This website uses the icons listed below as a guide to understanding the application uses and performance expectations of equipment advertised.
Economy Air Spray Painting Applications


Economy air spray painting guns would be classified as a cheap gun, designed to spray paint and give a reasonably good finish for the money. In most cases these guns would be considered "throw away" as the cost of servicing and spare parts would exceed the cost of a new gun. These guns offer exceptional value for DIY, Industrial & Professional spray painters where the finish is not critical.

Semi-Professional Air Spray Painting Applications  

Semi-Professional air spray painting guns would be classified as mid range all purpose guns. These guns deliver a good finish, lasting performance and may be serviced. Semi-Professional guns are commonly sold into markets such as DIY Car Restoration Finishes and Industrial Spray Painting Finishes such as fork lifts, truck bodies, rubbish bins and general metal re-finishing.


Professional Air Spray Painting Applications


Professional Air Spray painting guns are considered the industry best, used by professional spray painters and applicators that demand very high quality paint finishes that have been designed with the latest technology with lasting performance. Professional Air Spray painting guns are sold into the Automotive Refinishing, Kitchen Refinishing, Marine Refinishing and Aviation Refinishing markets that demand high quality.


What is the difference between Compliant, HVLP and Conventional Spray Guns?

  Compliant Air Spray Guns - Transfer Efficiency Over 65%

Finish Rating



Compliant air spray guns are very similar to HVLP spray guns. Compliant spray guns use a different air cap resulting in a higher head pressure than an HVLP spray gun. Compliant spray guns increase the rate of transfer efficiency by over 65%. Compliant air spray guns also help increase the speed of production, much like a conventional spray gun, but not with the wasted paint/finish particulate. Compliant spray guns also give off a better feel than HVLP spray guns because of the air cap difference. 



HVLP & LVLP Air Spray Guns - Transfer Efficiency Approx 50-65%

Finish Rating



HVLP (High Volume Low Pressure) air spray guns are designed to improve transfer efficiency. HVLP guns push paint particles at about half the velocity of conventional spray guns. While this means you have to spray closer to the surface, you gain by having more of the material applied to the object instead of floating into the air. The slower speed of application when using HVLP guns can be an issue for production line or large application jobs but a benefit when the operator requires more control over the spray finish.

LVLP (Low Volume Low Pressure) air spray guns work on the same principle as HVLP air spray guns but are designed to be use with lower output air compressors. In basic terms, you can spray effectively using a much smaller air compressor than you would required for a HVLP air spray gun. LVLP air spray guns will increase the transfer efficiency over HVLP air spray guns by about 10% but the application speed is greatly reduced. These guns are suited to DIY or home users where the reduced size of the air compressor could effect the performance of a conventional, HVLP or compliant gun.

  Conventional Air Spray Guns - Transfer Efficiency Approx 30-40%

Finish Rating



Conventional air spray guns have been around for a long time and would be considered "low-tech" against the modern HVLP and Compliant air spray guns. Although they will spray a very good finish, the transfer efficiency can be quite low anywhere between 30%-40% while requiring a higher air pressure to atomise the paint. In most applications air spray guns are suitable but if you are looking for a superior finish with less waste, look towards a HVLP or Compliant type of air spray gun.


Spray gun transfer efficiency explained.


What is air spray gun transfer efficiency?

Transfer Rating


Transfer efficiency (TE) of a spray operation or finishing process is the amount of material that adheres to the substrate compared to the amount of material that was sprayed through the spray gun toward the substrate.  Transfer efficiency is expressed as a percentage. *Transfer efficiency will vary with different paint materials, thinning and air pressure settings.

Suitable paint product applications.


A general guide to the various paint products that a gun will spray.

When choosing an air spray gun you should always refer to the paint manufacturer's data sheet, this will often recommend needle/nozzle and air cap set-up. All recommendations on this website are only a general guide from the air spray gun manufacturer.


These recommendations are based on AA Spray's opinion and experience with air spray painting equipment. The use of this guide is to help our customers make a better informed decision when purchasing an air spray gun, no warranty or guarantee is implied with this information.

1.0mm (.039) Siphon feed detailing or on a pressure feed system.
1.1mm (.043) Siphon feed detailing or on a pressure feed system.
1.2mm (.047) This tip size is generally for clear coats when a super-fine finish is desired. Recommended for clears that have a VOC of 3.5 or higher - lower VOC will be too thick for this orifice size. This tip will not "hose" material on, and will take a little longer to paint with due to it's very small orifice.
1.3mm (.051) A very common tip size used for clears, basecoats, waterbase and single stage paints, but low VOC single stage paint may be too thick for this orifice size. Produces a fine finish. Good atomization.
1.4mm (.055) A good "all around" tip. Generally, it can be used for clears, base coat and single stage. Use this tip if you are spraying clear with a VOC of 2.1. This larger orifice works well with thicker clears.
1.5mm (.059) The 1.5 is a versatile tip for base and single stage. Clears have a risk of "orange peel" if not sprayed carefully. This tip will also spray many primer sealers, conversion varnish, waterbased clears and lacquers.
1.6mm (.063) Used for "general purpose" applications, light to heavy viscosity materials.
1.7mm (.067) Widely used for primer, the 1.7 tip will apply thick primer quickly. Popular size for siphon feed guns.
1.8mm (.070) A little larger that the 1.7, primarily used for primer surfacers. Popular size for siphon feed guns.
2.2mm (0.87) Extremely large tip. Designed for "high build" primers. May be used to spray fiberglass resin, and coatings greater than 60 seconds in a #2 Zahn cup.
