The AirTAC GFR600C25MLF2GK AirTAC Filter Regulator G1 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 AirTAC GFR600 series combines water and particulate filtration with pressure regulation in a single body. This GFR600C25MLF2GK is the size-600 unit with a G1 (1 in) G-thread port, a manual drain, the standard 40 um filter element, a low-pressure regulator, an embedded square gauge reading in psi, a fitted reverse (check) valve and the mounting bracket included. The size-600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in up to 1 in and options including automatic or manual drains, a 5 um filter element (code W), MPa, psi or bar gauge scales, and G or NPT threads in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow data 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. 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.

Filter and regulate plant air feeding cylinder manifolds on an automotive trim and assembly line. The manual drain suits a site with scheduled maintenance rounds, and the psi square gauge lets US technicians set and verify line pressure at a glance.
Regulate supply to low-pressure air knives that blow water off bottles or cans after washing. The 40 um element protects nozzle orifices from particulate, and the low-pressure regulator type matches circuits that run well below full line pressure.
Supply filtered, regulated air to clamp and stopper cylinders on a packaging conveyor. The fitted check valve blocks backflow toward the unit, holding the downstream circuit stable when upstream pressure dips.
Choose the size and port step against the flow your line needs: the 600 size with its G1 (1 in) port is the largest step in the GFR range, with 200, 300 and 400 below it. Drain type is a real choice: this unit uses a manual drain (code M), while automatic (A) and differential-pressure (blank) variants exist in the same series. Filter grade is the standard 40 um element; specify code W for the 5 um option where finer particulate removal matters. The F2 gauge code gives the embedded square gauge with a psi scale; MPa and bar scales and an external round gauge are available. The thread here is G (BSPP); PT is the standard thread and G or NPT are order options. The mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 this series as curves rather than a single rated figure, so we do not quote a number on the page. Send us your application details and we will confirm the flow data from the datasheet on request before you order.
The bowl collects the water separated from the compressed air, and with the M code you open the drain valve yourself as part of routine maintenance. If you prefer unattended operation, automatic (A) and differential-pressure (blank) drain variants are available in the same GFR600 series.
