Iwata Air Cap Selection Chart & Overview

Published by hans_merscher on

This is the most comprehensive Iwata Air Cap (SYNO: Air Nozzle) selection chart covering more than 48 different air caps. The guide enables the user to find the correct part number based on the air cap color, number or code that is stamped on the air cap. It also provides information suc as:

  • Pressure Operating Range (bar and psi)
  • Air Flow (lpm and scfm)
  • Pattern Size (mm and inch)
  • Air Cap/Nozzle Type (whether conventional, HVLP or LVMP)
  • Iwata Part Number
  • Iwata Spray Gun Model the air cap is used in

The guide includes the Iwata W400 (including W400 LV4), Kiwami, WS400, LPH400 (orange and silver), W71, W77, LS-400 Supernova, WS-400HD Supernova, LPH50, LPH80, RG3L, LPH101, LPH200, W101, W200 and W300.

Atomizing Air Pressure

The recommended atomizing air pressure, both in bar and psi, helps to set up the spray gun to the right pressure.

Air Flow Rate (Air Consumption)

The air flow rate, both lpm (liter per minute) and SCFM (standard cubic feet per minute), helps to determine the size of the compressor that is needed to operate the spay gun.

Maximum Spray Pattern Size

The maximum spray pattern is highly dependent on the nozzle size used, i.e. the same air cap will provide a wider spray pattern when used with a larger nozzle size. Another factor is whether the spray gun is used as a “gravity feed”, “suction feed” or “pressure feed”. Pressure-feed guns tend to produce the widest pattern, followed by gravity and then suction (in that order). Iwata usually has separate air caps for pressure-feed guns, while gravity and suction guns often share the same air cap. In this case, the guide will give the overall maximum spray pattern (which is then taken from the gravity feed).

Iwata Air Cap Test Kit

Iwata Air Cap Test Kits (often referred to as “Air Cap Gauges”) are available for most HVLP models to measure and verify that the maximum allowable pressure of 10 psi is not exceeded.
