The AirTAC GFR60025LC2WGK AirTAC Filter Regulator G1 Low-Pressure 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 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 GFR60025LC2WGK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This is the large size-600 unit with a G1 (1 in) G-thread port, built for main-air supply points on bigger installations. It is the low-pressure (L) regulator type, fitted with the W fine filtration element (5 um) for cleaner air than the standard 40 um grade, an external round gauge scaled in psi, and a reverse/check valve that holds downstream pressure when the upstream supply drops. The drain is the differential-pressure type, which bleeds accumulated condensate automatically as the pressure differential across the element builds, and the aluminium alloy bowl suits the 600 frame. Maximum working (inlet) pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow 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.

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.

At the 1 in main-air drop feeding a packaging hall, the unit strips water and 5 um particulate from the supply and holds a steady low set pressure to the case-packing and sealing machines, while the check valve keeps downstream circuits pressurised during upstream dips.
On a process skid where transmitters and pneumatic control relays sit on a shared header, the 5 um element protects the instruments from condensate and fines, and the low-pressure regulator type suits the modest set pressures these instruments expect.
Feeding the pneumatic clamping circuit of a CNC machining cell, the regulator holds the clamp pressure steady through cycle-to-cycle demand swings, the psi gauge lets setters verify setpoint at a glance, and the differential-pressure drain clears condensate without operator attention.
Size and port set the capacity: this is the 600 frame with a G1 (1 in) port, the largest step in the GFR range - step down to 200/300/400 with smaller ports when your line flow is modest. Filtration is the W element at 5 um; choose it where downstream valves and instruments need finer air than the standard 40 um grade. The L low-pressure regulator variant is intended for lower set pressures than the standard type; its exact adjustment range is not published in the material we hold, so confirm it with us before ordering. The round gauge here reads in psi; embedded square gauges with MPa, psi or bar scales are the alternative. The K code adds a reverse/check valve, and the differential-pressure drain works unattended - a manual-drain (M) or automatic-drain (A) version can be ordered instead. Thread is G here; PT is the standard and NPT is an order option, and a bracket is included with this unit.
Flow for this family 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. The reflux valve permits reverse flow 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 there is no one rated flow number we can quote. Send us your line pressure and demand and we will confirm the sizing from the datasheet on request - no estimate is given here.
The L code marks the low-pressure regulator variant, intended for lower set pressures than the standard GFR type. The exact adjustment range for this variant is not published in the material we hold, so confirm the range with us before ordering. Everything else on this unit is standard decode: 5 um W filtration, differential-pressure drain, round psi gauge, reverse/check valve, G-thread G1 port and included bracket.
