Spray tips An overview


Airless Spray Tips atomise without air, hence the name. They work when a pump supplies the material to be sprayed at high pressure forcing the material through the tip orifice at pressure. The Airless tip atomises the material at the flow rate and spray width determined by the tip as the coating passes through it and expands. Airless Air Assisted AAA tips work in a similar manner, the difference is that by adding compressed air assistance, lower fluid pressures can be used. This saves energy and paint and this is achieved without creating hard edge spray patterns or tailing. The wide choice of tips provided is to meet the demands of the wide range of coating materials that can be sprayed. Each type is designed to help the user to get the best of results. Tip Wear


Tips do wear. Factors that affect wear are; fluid pressure, abrasiveness of coating, quantity of coating sprayed. When you see a spray width reduction, check the tip and if it is badly worn, replace it before it costs a great deal of money in time and paint wasted. Paint is wasted when too much is put on the job! Tip replacement will cost much less. Tip Selection Careful selection will reduce waste and give better control. Choose a tip to suit the coating and ensure the tip does not have a greater output than the spray machine. Choose the spray fan width to suit the job. The wider angle tips eg 70 or 80 degrees are best suited for fast coverage on large flat or uninterrupted areas such as factory walls, ships hulls etc. If a job has a mix of surfaces such as steel fabrications or more complex building spaces, then use a narrower tip angle. The Exitflex Twin tip has two spray widths in the same key! The orifice controls the output, so a narrower spray fan needs a faster movement at the spray gun than the wider spray fan. As a guide:- Not enough paint. Choose a larger orifice/ reduce spray angle. Too much paint. Choose a smaller orifice/ increase the spray angle. Tip Markings


All the tips in the Exitflex range are marked with the first digit as the angle. Where the angle reaches 100 degree or above it becomes the first two digits. The orifice size is the last two digits. eg, 517 = 50 degree (approx 10 inches wide) and a 0.017in orifice.The chart provided on page 16 shows a guide to the volume output on water at 100 Bar.
