The AirTAC GFR600C25LC2GK 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 GFR600C25LC2GK is an AirTAC GFR-series filter regulator: one body that strips water and particulate from compressed air and holds downstream pressure at your set point. This 600-size unit carries a G1 (1 in) G-thread port, is rated to 1.0 MPa (145 psi) maximum inlet, and operates from -5 to 70 C (non-freezing). The 40 um standard element covers general-purpose filtration, the differential-pressure drain is the series default for condensate removal, and the low-pressure regulator type is intended for circuits set below standard line pressure. A round gauge on a psi scale is fitted for direct set-point reading, a reverse/check valve is included, and the mounting bracket is included with the unit.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus automatic or manual drains, a 5 um (W) element, alternative gauge styles and scales, and a low-pressure type. Because flow for this series is published as curves rather than a single rated figure, we do not quote a number here - send us your application details and we will confirm sizing and the full datasheet on request.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.

Filtering and regulating the low-pressure air that actuates hold-down clamps on a CNC router, with the fitted round psi gauge giving the operator a direct set-point readout at the machine and the 40 um element protecting the clamp valves.
Conditioning the 1-inch main air feed that drives stopper and pusher cylinders along a bottling-line conveyor, with the differential-pressure drain handling condensate and the reverse/check valve holding the downstream circuit.
A single filter-regulator at the inlet of a carton-sealing machine, bracket-mounted beside the air drop, holding a reduced low-pressure supply for the tucking and sealing cylinders on the packaging line.
Size and port: the 600 size is the largest in the GFR range and carries the G1 (1 in) port on this code; step down to 200, 300 or 400 with smaller ports if your demand is lower - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Drain: this unit uses the differential-pressure drain (the series default); automatic (A) and manual (M) drains are orderable. Filtration: the 40 um element is standard here; specify W for the 5 um grade. Gauge: a round gauge on a psi scale is fitted; embedded square gauges and MPa or bar scales are the other catalogue options. Thread: G (BSPP) is on this code; PT is the standard thread and NPT is an order option. A mounting bracket is included, and the low-pressure regulator type suits circuits set below standard line pressure - we can confirm its exact adjustment range 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 curves, not as a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow curve and sizing from the datasheet on request.
The trailing G on this model is the G (BSPP) parallel thread option. PT is the standard thread for the series and NPT is also a catalogue option; all three are specifications you order, and we confirm the exact variant on your datasheet on request.
