The AirTAC GFR600-25MLJC3WT AirTAC Filter Regulator NPT 1 in is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600-25MLJC3WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is built around a 1 in NPT port, so it suits the main air supply of a large installation rather than an individual drop. The W grade gives a 5 um filtration element for finer protection than the 40 um standard, the M code specifies a manual drain you open by hand to empty the bowl, and the L code selects the low-pressure regulator type for circuits that run below standard working pressures. The C3 code fits an external round gauge reading in bar, and the J code means the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding filtered, regulated air to spray guns and air-assisted applicators on a finishing line, where the 5 um element helps keep water and particles out of the finish and the low-pressure type matches reduced booth supply pressures.
Conditioning the 1 in main air feed that serves carton sealers, case erectors and bagging machines along a packaging conveyor, with the manual drain emptied during scheduled line cleaning.
Supplying clean, regulated low-pressure air to lab-scale process equipment and test rigs, where the round bar gauge gives a clear local pressure readout at the skid.
Start with the port: this configuration is 1 in NPT, the largest step in the GFR range, so size up to 600 only when your line flow genuinely needs it - smaller sizes 200-400 cover 1/8 in to 3/4 in ports at lower cost. Choose the drain deliberately: manual (as here) means an operator empties the bowl, while automatic or differential-pressure drains suit unmanned installations. Pick 5 um (W) when downstream valves or instruments need finer protection than the 40 um standard. The gauge here is the external round type reading in bar; an embedded square gauge with MPa, psi or bar scales is the other route. Thread is NPT on this unit, with PT (the standard) and G available as order options, and the J code omits the bracket - add one if you want panel or wall fixing.
Be aware this is the L low-pressure regulator type, so confirm its regulation range suits your circuit before ordering. Because flow for the GFR series is published as curves rather than one rated figure, send us your application details and we will confirm sizing against the datasheet on request.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as characteristic curves, not as a single rated number, so we do not quote a flow figure for this unit. Tell us your application - supply pressure, downstream demand and acceptable pressure drop - and we will confirm the relevant datasheet curve and sizing on request.
The M in the code selects a manual drain: condensate collects in the aluminium bowl and an operator opens the drain by hand, which suits attended installations on a maintenance schedule. The L code selects the low-pressure regulator type, intended for circuits that run below standard working pressures; its exact regulation range is not published in the general catalogue data, so ask us to confirm it against the datasheet before ordering.
