The AirTAC GFR60025LC2GK 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 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 GFR60025LC2GK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure, in one body. This configuration is the 600 size with a G1 (1 in) G-thread port, the low-pressure regulator type, a differential-pressure drain, the standard 40 um filter element, a round gauge reading in psi, a reverse (check) valve fitted, and the mounting bracket included. At size 600 the drain bowl is aluminium alloy.
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, and can be ordered with manual or automatic drains, a 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures 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. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeds a filtered, pressure-controlled supply to impact drivers and pneumatic clamps at assembly stations, with the check valve holding the set pressure against backflow on the drop.
Conditions the shop air feeding tool-changer cylinders and clamping fixtures, keeping water and swarf out of the valves while the low-pressure type holds the circuit at its set point.
Serves the air cylinders that divert, clamp and seal product on a packaging conveyor, with the 1 in port sized for a main line feeding multiple stations.
Step up to the 600 size when your line's air demand calls for the largest G-series port step; here that is G1 (1 in) in G thread, with PT as the standard thread and G or NPT available as order options. The L in the code marks the low-pressure regulator type, the choice for circuits held below standard line pressures; its exact adjustment range is not published, so confirm it with us. Drain is the differential-pressure default; automatic (A) and manual (M) drains are the alternatives. The element is the standard 40 um grade; order the W suffix for 5 um. The round gauge reads psi; embedded square gauges and MPa or bar scales are options. Flow is published as curves, not a single rated figure, so send us your flow requirement and we will confirm sizing against the datasheet before you order.
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 GFR600 as curves rather than a single rated number, so we do not quote a figure here. Send us your required flow and line pressure and we will confirm against the datasheet whether this 1 in unit is correctly sized for your application.
It marks the low-pressure regulator type, intended for circuits held below standard line pressures. The exact adjustment range for this type is not published in the material we hold, so ask us to confirm it before ordering. The rest of the code decodes as: G1 (1 in) G thread, differential-pressure drain, 40 um element, round psi gauge, fitted check valve, bracket included.
