ANEST IWATA Spray Gun Accessories: Which Cup, Regulator, Filter and Hose Fit Your Gun

You picked an ANEST IWATA spray gun. Now you need the parts that go with it: a cup that fits the gun's thread, a regulator so you spray at the right pressure, clean dry air, and a hose that does not fight you. This guide explains how to match ANEST IWATA cups, regulators, filters and hoses to the gun you have, using the maker's own figures. For choosing the gun itself, see our ANEST IWATA spray gun guide.

Quick answer
  • Which cup fits? Check the gun's cup thread. Small guns (WIDER1, WIDER1L, KIWAMI-1, W-50, W-61, W-71, W-101, LPH-101) take G1/4 cups. Large guns (WIDER2, WIDER2L, W-77, W-200) take G3/8 cups.
  • Gravity or suction? Match the gun. A gravity gun (cup on top) takes a gravity cup; a suction gun (cup below) takes a suction container.
  • Regulator: RR-A (one-sided adjustment), RR-AS (both sides adjustable) or RR-AT (higher pressure). For a gauge on the gun itself, the AJR-02S-VG.
  • Clean air: ALF1300B-14D (3 µm) for dust and water, AMF1200B-14D (0.01 µm) for oil mist.
  • Hose: EAHU-620 (single, with ground wire) or THU-620 (twin, for pressure-feed guns).

1. Cups: match the thread and the feed type

ANEST IWATA lists a mounting thread and the compatible guns for every cup. Two threads cover almost all hand guns in our store:

Cup Type Capacity Thread Material Compatible guns (maker's list) Made in
PC-400SB-2LF Gravity 400 ml G1/4 Stainless, with legs WIDER1, WIDER1L, KIWAMI-1, W-101, 71, 61, 50, LPH-101, RG-3L Taiwan
PC-400S-2LTF Gravity 400 ml G1/4 Stainless; complies with Japan's Food Sanitation Law Same as above Japan
PC-400AB-2LF Gravity 400 ml G1/4 Aluminum, 125 g Same as above Taiwan
PC-150SB-2LF Gravity 130 ml G1/4 Stainless Same as above Taiwan
PC-51 Gravity 220 ml G1/4 Stainless WIDER1, KIWAMI-1, W-101, 71, 61, 50, LPH-101, RG-3L Japan
PC-61 Gravity 130 ml G1/4 Stainless Same as PC-51 Taiwan
PCG-6P-2 Gravity 600 ml G1/4 Resin LPH-50, LPH-101, W-50, W-101, W-61, W-71, RG-3L Italy
PC-4 Gravity 400 ml G3/8 Aluminum WIDER2, WIDER2L, W-200, W-77 China
PC-3 Suction 400 ml G1/4 Aluminum WIDER1, W-101, 71, 61, LPH-101 Taiwan
PCL-7B-3 Suction 700 ml G3/8 Die-cast aluminum WIDER2, WIDER2L, W-200, W-77 Taiwan
PC-1 Suction 1000 ml G3/8 Die-cast aluminum WIDER2, WIDER2L, W-200, W-77 China

Compatibility lists and figures are ANEST IWATA's, as shown on each product page. The cups for W-300 and LPH-300 (PCG-2P-2, PC-G400P-2) and the WS-400 (PC-G600P-2) are also in our cups collection. A cup with the right thread but the wrong feed type will not work: a gravity cup on a suction gun has no way to draw paint.

ANEST IWATA PC-400SB-2LF stainless gravity cup with legs

Gravity cups for small guns: PC-400SB-2LF and family

For a WIDER1, KIWAMI-1 or W-71 gravity gun, the 400 ml stainless PC-400SB-2LF is the standard choice. ANEST IWATA notes that the stainless cup has legs and stands on its own (210 g). The PC-400S-2LTF is the same size in a version that ANEST IWATA lists as complying with Japan's Food Sanitation Law, for food-contact work. If weight matters, the aluminum PC-400AB-2LF is 125 g. For small jobs or touch-ups, the PC-150SB-2LF (130 ml), PC-51 (220 ml) and PC-61 (130 ml) hold less paint and sit lower on the gun.

ANEST IWATA PC-4 aluminum gravity cup for large guns

Cups for large guns: PC-4, PCL-7B-3 and PC-1

WIDER2, W-77 and W-200 guns use the larger G3/8 thread. The PC-4 is a 400 ml aluminum gravity cup. For suction guns in this size, the PCL-7B-3 holds 700 ml and the PC-1 holds 1000 ml, both in die-cast aluminum.

ANEST IWATA PC-3 suction container 400 ml

Suction container for small guns: PC-3

If your W-71, W-101 or WIDER1 is the suction type (cup hangs below the gun), the PC-3 is the matching 400 ml aluminum container with a G1/4 thread (180 g).

2. Regulators and gauges: set the pressure where it matters

ANEST IWATA RR-AS air transformer with two gauges

RR-A, RR-AS and RR-AT air transformers

ANEST IWATA's RR series are air transformers: a regulator with a gauge that you mount near the work. All three take 1/4" (G1/4) connections and pass 780 L/min.

  • RR-A: one adjustable outlet. Primary pressure up to 1.0 MPa, secondary 0.05–0.78 MPa. 2.9 kg.
  • RR-AS: pressure adjustable on both sides. Same pressure figures as the RR-A.
  • RR-AT: for higher-pressure lines. Primary up to 1.4 MPa, secondary 0.05–1.13 MPa.

All three are made in Taiwan and rated for air up to 80 °C.

ANEST IWATA AJR-02S-VG handheld pressure gauge at the gun inlet

AJR-02S-VG and AJR-02L-VG: a gauge at the gun

Pressure drops along the hose, so the number at the wall is not the number at the gun. The AJR-02S-VG screws onto the gun's G1/4 air inlet and lets you read and adjust pressure right there (screw adjustment, max 0.68 MPa, brass body, 120 g, made in Italy). The AJR-02L-VG is the rotary version (95 g, made in Japan).

3. Air filters: dust, water and oil mist

ANEST IWATA AMF1200B-14D micro mist filter

ALF1300B-14D and AMF1200B-14D

Compressor air carries water, dust and oil mist, and each of them shows up as a defect in the finish. ANEST IWATA's line filters are rated by what they remove:

  • ALF1300B-14D: main line filter, 3 µm, automatic drain, Rc3/8 port, 1300 L/min at 0.7 MPa, 0.9 kg. Removes dust and condensed water.
  • AMF1200B-14D: micro-mist filter, 0.01 µm, Rc3/8 port, 1200 L/min at 0.7 MPa, 0.9 kg. Removes fine oil mist.

Both are rated to 1.4 MPa and made in Japan. A coarser filter is normally placed upstream of a finer one.

4. Hoses and fittings

ANEST IWATA EAHU-620 yellow urethane air hose with ground wire

EAHU-620 and THU-620 urethane hoses

The EAHU-620 is a 20 m urethane air hose, 6.2 mm inside and 9.3 mm outside, with a ground wire to carry away static, rated to 1.47 MPa (0.95 kg, made in Japan). For pressure-feed guns that need an air line and a paint line together, the THU-620 is a twin urethane hose of the same size, 2 × 20 m, rated to 0.69 MPa (1.8 kg, made in Japan). The AJQ-02PM quick-joint plug connects an air hose to a coupler.

5. Paint-side accessories

ANEST IWATA SFX-179-200 paint filter for spray gun

SFX-179-200 paint filter, NK-2 viscosity cup, AMM-6B mixer

The SFX-179-200 is an in-line paint filter (200 mesh equivalent) for W-101, W-71, W-61, LPH-101 and WA-101 guns, rated to 0.7 MPa (43 g, made in Japan). The NK-2 is a brass viscosity cup (46 mm cup, 273 mm long) for checking how much to thin the paint. The AMM-6B is an air-powered handheld paint mixer, 10 × 600 mm shaft, for paints up to 1 Pa·s.

ANEST IWATA PT-10D paint pressure tank 10 L

Pressure tanks: PT-10D, PT-10DM and PC-18D

For long jobs with a pressure-feed gun, a pressure tank replaces the cup. The PT-10D is a 10 L steel tank with manual agitation, 0.34 MPa maximum, G1/4 air inlet and G3/8 paint outlet (13 kg). The PT-10DM is the same tank with automatic agitation (14 kg). For smaller batches, the PC-18D is a 2 L pressurized container, 0.34 MPa, G3/8 thread (1.25 kg). See all pressure tanks.

How to choose

Start from the gun. Find your gun model in the cup's compatibility list, and check the thread (G1/4 or G3/8) and feed type.

Then fix the air. A regulator you can see from where you spray, a gauge at the gun if the hose is long, and filters if you see fisheyes or water spots.

Check the fittings. ANEST IWATA guns use G (BSP parallel) threads. NPT fittings common in North America are not the same thread, so order ANEST IWATA fittings or adapters with the gun.

FAQ

Which cup fits the WIDER1 or KIWAMI-1?

Any G1/4 gravity cup in the table: PC-400SB-2LF, PC-400S-2LTF, PC-400AB-2LF, PC-150SB-2LF, PC-51 or PC-61.

Which cup fits the WIDER2 or W-77?

G3/8 cups: PC-4 for gravity guns; PCL-7B-3 or PC-1 for suction guns.

Do I need both filters?

The 3 µm ALF filter handles dust and water; the 0.01 µm AMF filter handles oil mist. For finish work, ANEST IWATA offers both; which you need depends on your compressor and the defects you see.

Will US (NPT) fittings fit?

ANEST IWATA uses G (BSP parallel) threads. NPT is a different thread. Use ANEST IWATA fittings or a G-to-NPT adapter.
