The AirTAC GFR600C25MLJC3TK AirTAC Filter Regulator NPT1 Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C25MLJC3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is built for a 1 in NPT port and carries a manual drain (code M), the standard 40 um filter element, a metal bowl (aluminium alloy at size 600), a fitted round gauge reading in bar, a reverse (check) valve (code K) and the low-pressure regulator type. No mounting bracket is included (code J). Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, PT/G/NPT thread and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before you order.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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.

On a 1 in main feed serving a bottling hall's ring main, this GFR600 filters compressor carryover water and particles and regulates the header at a low set pressure, with the bar gauge giving a local reading at the line.
Palletizer clamp and pusher cylinders fed from a 1 in drop get cleaned, regulated air from this unit; the manual drain fits a shift-based maintenance routine and the fitted reverse valve is part of the circuit design.
Looms and spinning frames run many small cylinders off a shared header; a size 600 filter regulator at the header cleans the supply and holds a low working pressure, with the 40 um element protecting the downstream valves.
Size and port step up together: 200 through 600 cover 1/8 in to 1 in, so choose the size whose flow curve covers your demand - we can check the curve against your application before ordering. Drain on this code is manual (M): you drain the bowl by hand, which suits installations on a regular maintenance round; automatic and differential-pressure drains are available on other codes. Filtration is the standard 40 um element; specify W for the 5 um grade if finer particle capture is needed. The fitted round gauge reads in bar; an embedded square gauge and MPa or psi scales are catalogue options. Thread is NPT on this code; PT is the standard and G (BSPP) is also available to order. No bracket is included (J); brackets are optional. The regulator is the low-pressure type - confirm its adjustment range against your set pressure with us before ordering.
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 curves, not as a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm against the GFR600 datasheet whether this 1 in NPT size covers your application.
Code M means the bowl is drained by hand, which suits lines checked on a regular maintenance round. The same GFR600 body is available with automatic (A) or differential-pressure (blank) drain - tell us your preference and we will quote the matching code.
