Iwata Eclipse HP-CS Review: Specs, Pressure, Paints and Who It Suits

What Iwata says it is for

Iwata sorts its airbrushes into five spray categories. The Eclipse series is "All-Star Versatility": airbrushes that, in Iwata's words, can easily atomize heavier sprayable mediums from a controlled fine line to a controlled wide spray. That puts it between the beginner "Effortless Coverage" group (NEO and Revolution, soft coverage at low pressure) and the "Total Control" Hi-Line and High Performance Plus models, which aim at fine detail with adjustable airflow.

The HP-CS product page backs that up. Iwata says its high flow handles a wider range of liquids with less reducing or thinning, from thin to thicker viscosity and pearlized materials, and it pitches the airbrush at hobbyists and professionals from beginner to advanced. In practice that means scale models, auto graphics, illustration, fabric, cosplay props and craft work, the jobs where you switch between paints often.

The compression-fit nozzle

Most airbrushes have a tiny nozzle that screws into the body. Over-tighten it and it splits; cross-thread it and the body is damaged. The Eclipse instead uses a compression-fit nozzle that sits in the head and is clamped by the head cap. Iwata's cleaning guide says to remove the head cap with the supplied head cap wrench and never to separate the nozzle from the head set or use Iwata's nozzle wrench on it. Iwata's airbrush basics page adds that the compression-fit nozzle is easy to install and clean and handles thicker material without clogging.

Iwata does not print nozzle sizes on its product pages (its basics page says it deliberately does not emphasize them). Iwata-Medea's own Amazon listing for the replacement nozzle used in the Eclipse CS, BS and SBS gives 0.35 mm.

What compressor it needs

Iwata's 25 to 35 psi working range rules out the smallest hobby compressors. Iwata's own Ninja Jet works at 1 to 15 psi, for example, which suits the NEO but not the Eclipse. Iwata's Smart Jet Pro (1 to 30 psi working, 50 psi maximum, auto shut-off and a moisture filter) is its own match. Among cheaper tank compressors, the Master TC-326T (shuts off at 57 psi, per its listing) and the Timbertech ABPST08 both have the headroom, a 3 liter tank, a regulator and a water trap. Our compressor guide compares them.

Iwata's 25 to 35 psi is a starting band, not a rule: thin inks and detail work often go lower, and the paint maker's own figure wins (see the airbrush PSI chart).

Strengths

• Range. Fine to wide on one airbrush, and Iwata rates it for thicker and pearlized materials.
• A nozzle that is hard to ruin. No threads to crack or strip.
• Quick-flush cutaway handle. The single-cut handle exposes the needle chucking nut, so you can pull the needle back to flush without taking the handle off.
• Solvent-resistant needle packings (per the Amazon listing), so it takes solvent-based automotive and lacquer paints as well as water-based ones.
• Parts. Iwata-Medea sells E3 needles, nozzles and caps through dealers and on Amazon.

Weaknesses

• More air than a beginner airbrush. Budget for a compressor that holds 25 to 35 psi steadily.
• Not a hairline detail airbrush. For freehand portraits or eyes on 28 mm figures, a 0.2 mm or smaller airbrush (Iwata's Hi-Line or Harder & Steenbeck's Infinity) does better. See airbrushes for miniatures.
• Iwata publishes no warranty terms on the product page. Its Amazon listings vary: the Revolution CR listing says five years limited, the HP-CS listing only "manufacturer warranty". Register it with Iwata and keep the receipt.

In the box and spare parts

Iwata ships the HP-CS with a head cap spanner (for removing the head cap to clean the nozzle) and Iwata Lube for the needle and main lever. Iwata-Medea sells E3 needles, nozzles and caps separately; Iwata's cleaning guide suggests keeping a spare needle and nozzle if you airbrush often, and replacing a cracked nozzle or bent needle rather than repairing it.

Cleaning the Eclipse HP-CS

Iwata's cleaning guide covers the Eclipse HP-CS. Spray cleaner or water through until it runs clear at every color change and at the end of a session. For a deeper clean, pull the needle and wipe it toward the point only, then soak the nozzle and caps for no more than 10 minutes. Never soak or "wet dock" the whole airbrush, and never store it with paint or cleaner in the cup. Iwata also warns that the nozzle contains nickel, worth knowing if you have a nickel allergy.

HP-CS or something else?

• Brand new and on a tight budget: the NEO for Iwata CN sprays at 8 to 20 psi on a small compressor. Our Eclipse vs NEO comparison goes deeper.
• Large areas, fabric and big batches: the siphon-feed HP-BCS takes a 2 oz bottle, at 35 to 55 psi.
• Fine detail first: the Harder & Steenbeck Infinity 2024 with its 0.25 mm titanium nozzle.
• Everything else: the HP-CS. Keep it clean (see how to clean an airbrush) and it is an airbrush you will not need to replace.
