The AirTAC GFR600C25MLC2G 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 GFR600C25MLC2G is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This size 600 unit is built around a G1 (1 in) port with G (BSPP) thread, carries the 40 um standard filter element and a manual drain on the metal bowl, and uses the low-pressure regulator type. A round gauge scaled in psi is fitted so the setting can be read directly, the mounting bracket is included, and no reverse/check valve is fitted. On this size the bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge and thread options, and standard or low-pressure regulation. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.

Feeding a press or clamping-fixture circuit where air must be cleaned of water and pipe scale and the clamp pressure held at a low set point; the fitted round psi gauge lets the setter read the regulated line directly.
A point-of-use filter regulator on a 1 in drop from a factory air ring main, protecting downstream valves and cylinders from condensate and scale ahead of a low-pressure process station.
Supplying conveyor gate and stopper cylinders on a bottling or canning line, where a manual-drain metal bowl suits a planned shutdown routine and the low-pressure regulator matches light actuator loads.
Start with the port step: size 600 with a G1 (1 in) port is the largest G-series size, so match it to the line size and the flow your circuit needs - we confirm figures from the datasheet on request because flow is published as curves, not a single rating. Then set the drain: this unit is manual, meaning the bowl is vented by hand on a routine; choose automatic or differential-pressure drain if the unit is hard to reach. The filter grade here is the 40 um standard element; specify W for the 5 um option where finer particulate protection matters. The regulator is the low-pressure type, so confirm its setting range against your set point before ordering. Gauge scale (MPa, psi or bar), thread (PT is the standard, G or NPT as catalogue options) and bracket choice complete the configuration.
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 rather than a single rated figure, so we do not quote a number here. Tell us your line size, inlet pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request.
This unit has a manual drain: the metal bowl is vented by hand as part of a maintenance routine, which suits attended installations. If the unit sits in an inaccessible spot, order the same GFR600 configuration with the automatic or differential-pressure drain instead.
