The industry will accept recommendations for the max airless tip size. This is the best place to start, only this tip size will reflect the capabilities of a new automobile.
I believe information technology is all-time to use a smaller airless tip size than the manufacture recommends. This volition allow the pump to piece of work less and give yous more control. An example would exist a maximum tip size of 517, use a 515 instead.
The blazon of material being sprayed will determine the airless spray tip size. Varnish and oil base enamels are calorie-free, or thin, coatings and outside Acrylic/Latex paints are thicker and require larger tips.

Ideas and Basic Considerations
The 3 numbers used to describe a tip size, example 517, refers to the fan size and the orifice size. The fan size of a 517 is 10 inches wide, one human foot from the surface existence sprayed. The start number is ever 1/2 the actual fan width. The concluding 2 numbers refer to the actual size of the orifice. These numbers represent thousandths of an inch, example 517 is .017 inches.
With a abiding fan width, a larger orifice size volition apply more paint. Another example is a 515, information technology has an orifice of .015 inches and a 517 has an orifice of .017. the 517 applies more paint in the aforementioned amount of fourth dimension. Recall the smaller the orifice the less fabric will be applied.
Airless pigment spray tips wear out with use and this will change the fan width and orifice size. The fan will become more circular and smaller as the tip wears out.A 515 could become a 617 afterward fifty gallons or less of cloth sprayed. If you need to spray your unabridged house and your tip is already a fiddling worn, it would be best to buy a new airless spray tip. A worn tip tin can exist used for primer or end coats that volition be back rolled.
Recommendations
Consider the width of the surface to be sprayed. Deck railings are thin, iv inches or less so in that location is no need for a wide fan. A 211 tip applying outside deck stain volition have a fan of 4 inches and requite you great command. Some other consideration is the blazon. two types of airless spray tips exist, these are flat tips and reversible tips.
- Apartment tips do a good job and are the cheapest. These are available in many sizes, but require the use of a special airless tip housing and cannot be reversed to articulate a clog. A needle can be used to clear about clogs.
- Reversible tips are the currant standard for professional airless paint sprayers. When these clog turning the tip 180 degrees and pulling the trigger tin easily clear them. The clogging material is forced out past the force per unit area contained inside he paint gun.
A skilful combination of airless spray tips for general utilize would be a 311 for fine finishing and a 515 for production piece of work.
