Spray Guns Questions Ask a question for this category
Q: Does the W400 nozzle/needle kit work on the LPH400 guns?
A: The W400 or the W400LV nozzles and needles are specifically designed for those particular gun models. If you need a LPH400 LV nozzle/needle please chck the parts section of our website to confirm accurate part numbers.
Q: What is the size of fluid inlets for pressure guns?
A: The fluid inlet size depends whether you have a full size or compact size gun. Full size spray guns are 3/8″ and compact size guns are 1/4″.
Q: What is the air inlet size?
A: The air inlet size for all ANEST IWATA spray guns is 1/4″
Q: How can I get a parts breakdown?
A: Please visit the resources section of our website.
Q: What is the minimum compressor that would run the LHP50?
A: The LPH50 requires only 1.8cfm at 13psi therefore, a 1hp compressor would be the minimum to run the LPH50.
Q: Will the needle on a W-77 or a W-71 gun rust when using waterborne paint.
A: Our W-77 and W-71 Spray guns have stainless steel needles. However, the model numbers designated by an “N” have a hardened needle that may rust when waterborne paints are sprayed through them.
Q: Is there a way to identify the tip size of an ANEST IWATA spray gun.
A: Our spray gun nozzles are marked for your convenience. Remove air cap and the size is printed on the side of the nozzle.
Q: What does “Low impact” and “High Impact” mean on 8018 regulator?
A: The 8018 air regulator is marked “Low Impact” and “High Impact” for use with air tools.
Q: Are the needle/nozzles interchangeable?
A: Different combinations make-up different spray configurations. Our nozzles and needles are machine with interchangeable quality. You do not need to purchase matching set to complete rebuilds. Please visit the resources section of our website for particular nozzle, needle and air cap combinations located within the parts catalog.
Q: What is the difference between the W400 & the W200?
A: All 400 full size series spray guns are center post gravity feed. The 200 full size series spray guns are available in different fluid delivery configurations.
Q: What is the inlet pressure for a LPH400LV?
A: The air inlet pressure 16psi with the trigger pulled full.
Q: What is LV Technology?
A: LV Technology is a patented system within ANEST IWATA spray guns for pre-atomizing paint before leaving the nozzle while using less air pressure with lower air consumption than standard nozzles.
Q: What is the difference between a “W” gun & an “LPH” gun?
A: “LPH ” is our acronym for our HVLP spray guns. “W” is our acronym for our series of air-spray guns.
Q: What is a tulip spray pattern?
A: ANEST IWATA’s tulip spray pattern is “U” shaped where typical spray patterns are “V” shaped. The tulip spray patterns “U” shape enables paint to flow directly at specific substrate minimizing overspray. Unlike typical spray patterns that are “V” shaped and create paint overspray due to paint not being able to flow directed at specific substrate.
Spray Gun Maintenance Questions Ask a question for this category
Q: What tool should I use to remove air valve seat set from the gun body?
A: The air valve seat set should be removed with a 10mm allen wrench.
Q: What cup can I use with what gun?
A: Please visit the Products section of our website for further details.
Q: Will gun washers affect the performance of my spray gun?
A: No, however solvent should not be allowed to pass through the air passage and the needle packing may become dried and should be lubricated.
Q: Why is there paint residue in the air passage of my spray gun after placing in gun washer.
A: When using a gun washer your spray gun should always be positioned with the head of the gun angled down. The air inlet of the gun should be capped or sealed or the air valve closed as to not allow fluid into the air passage.
Q: I put my gun back together and I cannot adjust the pattern, what’s wrong?
A: Be sure the Pattern adjust set and the Air adjust set are installed correctly and have not been reversed during re-assembly.
Q: Do I need to remove the fluid & air inlets for thorough cleaning?
A: The Air and Fluid nipples do not need to be removed to thoroughly clean your spray gun. The Air and Fluid nipples should only be removed by qualified service persons.
Q: Can you order needles and nozzles separately or do you have to order them in match sets?
A: Our nozzles and needles are machine with interchangeable quality. You do not need to purchase matching set to complete rebuilds. However some pressure guns and specialty guns we recommend that both nozzle and needle be replaced. Please visit the resources section of our website for particular nozzle, needle and air cap combinations located within the parts catalog.
Q: What should I use to lubricate the moving parts of my spray gun?
A: ANEST IWATA spray guns should be lubricated with non-silicone lube.
Q: Does ANEST IWATA supply maintenance kits and service kits?
A: ANEST IWATA supplies maintenance and service kits for our equipment. Please visit the accessories section of our website for details.
Q: Is it OK to immerse my spray gun in solvent for cleaning?
A: You should never immerse your spray gun in solvent.
Q: After cleaning and reassembling my spray gun, I can not adjust the pattern size. It is always wide open.
A: a. Air adjustment set and the pattern adjustment set are reversed. b. Air cap set is not tight. c. Stem of pattern adjustment set is bent and should be replaced. (We suggest loosening knob of pattern and air adjustment set fully when assembling and disassembling) d. Air cap set and fluid nozzle are not seated properly because the L gasket on air cap set is loose or has been removed. (L gasket needs to be reinstalled or replaced)
Q: How do you convert a LPH 400 into a LPH 400LV or a W400 into a W400 LV?
A: This conversion may be completed by replacing nozzle/needle set-ups. This conversion should be performed by qualified service persons referencing our parts catalog. Please visit the resources section of our website for particular nozzle/needle combinations located within the parts catalog.
Spray Gun Technique Questions Ask a question for this category
Q: Can I spray upside down?
A: Spraying in an upward direction can be achieved by using a pressure gun or our gravity guns with side mounted gravity cup.
Q: What gun is best for base coats?
A: Since materials vary as do personal techniques it is almost impossible to recommend one gun for a particular application. Be sure to check with your coating manufacturer for Nozzle size recommendations.
Q: What gun is best for clear coats?
A: Since materials vary as do personal techniques it is almost impossible to recommend one gun for a particular application. Be sure to check with your coating manufacturer for Nozzle size recommendations.
Q: Will using a HVLP gun slow down my paint job?
A: HVLP technology is designed to reduce overspray and maximize transfer efficiency. HVLP air cap pressure is lower than standard air cap pressure, as a result the paint flow is lower than that of non-HVLP air spray guns. Due to our tulip spray pattern ANEST IWATA’s HVLP spray guns can acheive same spray pattern size at closer distance, therefore increaseing transfer efficiency.
Finishing Equipment Questions Ask a question for this category
Q: What material is the fluid passage on your diaphragm pump?
A: We offer diaphragm pump systems in various configurations that contain stainless steel or aluminum fluid passages.

Today’s Advanced Coating Materials Challenge Many Traditional HVLP Spray Guns
May 14th, 2005
It’s low-pressure with high atomization!
Today’s advanced coating materials challenge many traditional HVLP spray guns because of their atomization characteristics and high compressed air consumption. To continually offer coating solutions, ANEST IWATA developed LV (Low Volume) Technology featuring low air consumption coupled with superior atomization. LV spray nozzles utilize pre-atomization to create consistent paint particles combined with our tulip spray pattern allows today’s advanced coating materials to spray uniformly.
It’s low-pressure with high atomization!
ANEST IWATA continues to design solutions for today’s challenges.
