Shortlist we could verify

Master Airbrush Cool Runner II tank (SKU MAS TC-326T)

TCP Global, the Master Airbrush brand store, lists this as a 1/5 hp single-piston compressor with two cooling fans and a 3 L tank. The listing states 0.8 cfm / 25 L/min airflow, a diaphragm regulator with gauge, a water-trap filter, auto shut-off at 57 psi and turn-on at 43 psi, oil-less operation, and a manufacturer-stated noise level of 47 dB. The page title also uses the name TC-320T; the SKU on that same listing is MAS TC-326T.

Master Airbrush TC-40T

The same brand store lists the TC-40T as a single-piston Cool Runner with a 3 L tank, regulator, gauge, and water trap, plus two holders and a 6 ft braided hose. The copy describes air-on-demand delivery from the tank as “constant pressure & zero pulsation.” The official usage chart on TCP Global also records a related TC-20T (1/5 hp, 25 L/min, 57 psi max, 3.5 L tank, auto shut-off), but we did not find a current standalone TC-20T product listing to cite here, so it is not in the shortlist.

Sparmax TC-610H PLUS

Sparmax’s official product page describes a zero-maintenance, oil-less single-cylinder piston compressor with a 2.5 L tank and drain valve, a pressure regulator / moisture filter and gauge, a 3 m braided hose, two detachable airbrush holders, and a protective metal case. Product info on that page: airflow 23–28 L/min, weight 7.3 kg / 16 lb, size L30 × W14.5 × H36.5 cm, and a pressure switch of 40 psi on / 60 psi off. (The official web store lists a live selling price and slightly different case dimensions; we use the official product-page figures for specifications.)

Iwata Smart Jet Pro (IS875)

Iwata-Medea’s official page lists this as a compact compressor with low-to-medium output and an adjustable working pressure of 1–30 psi. Technical info: 110–120 V, 120 W, 1/8 hp, manufacturer-stated 59 dB, 20 L/min (0.71 cfm) at 60 psi, max pressure 50 psi, auto shut-off yes, air storage tank capacity “No,” regulator yes, net weight 11.84 lb / 5.37 kg. It includes a moisture filter, regulator and gauge, a protective case with a holder, a hose, and adaptors for Badger, Aztek, and Paasche brushes.

Iwata Power Jet Pro (IS975)

Official listing: a dual-station compressor with low-to-high output, working pressure 1–50 psi, a 2 L tank, two regulators, two gauges, and two moisture filters. Technical info: 155 W, 1/6 hp, manufacturer-stated 62 dB, 31 L/min (1.08 cfm) at 60 psi, max 75 psi, auto shut-off yes, 25.84 lb / 11.72 kg. Iwata’s compressor guide says that once the tank is full the motor shuts off and you can spray from stored air, with the motor restarting when the tank is empty.

How to choose

• Tank or no tank. Iwata’s guide lists three tank advantages: nearly silent spraying while using stored air, more motor rest, and cooling of stored air. See tank vs tankless.
• Regulator and moisture control. Every shortlist model above is listed with a regulator and a moisture filter or trap. That pairing is what lets you set a low working pressure and knock down condensation before it reaches the brush.
• Working pressure vs max pressure. Official working ranges vary: Smart Jet Pro 1–30 psi; Power Jet Pro 1–50 psi; Cool Runner II auto-cycles 43–57 psi at the tank switch (you still set working pressure at the regulator). Match the compressor’s stated working range to the airbrush: NEO CN’s official optimal range is 8–20 psi; Eclipse HP-CS is 25–35 psi.
• Noise. Use the manufacturer’s dB figure as a rating, not a room measurement. Details on the apartment noise page.

Pair the compressor with a vented booth and a dual-action gravity brush. For fumes and ventilation language, see indoor spraying notes — that page quotes equipment manuals and Acrylicos Vallejo’s official MODEL AIR SDS (Section 8.2 B: “Filter mask for particles”; Section 4.1 on moving to “fresh air” if inhalation symptoms occur) and is not safety advice.
