The AirTAC GFR60025C2GK AirTAC Filter Regulator G1 Round Psi Gauge 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 AirTAC GFR60025C2GK is a 600-size filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is threaded G1 (1 in) in G thread, carries the standard 40 um filter element, drains condensate by differential pressure, and is fitted with an external round gauge reading in psi plus a reverse (check) valve. The bowl on this size is aluminium alloy, and the standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing.
It is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, thread options PT, G and NPT, manual or automatic drain alternatives, a 5 um (W) filter grade option and a choice of gauge styles and scales. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |

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 clean, regulated air to the pick-and-place cylinders and grippers on a carton-forming and sealing line, with the check valve holding downstream pressure if the supply dips.
Conditioning the supply to bench-top lab instruments and their pneumatic actuators, where condensed water and pipe-scale particles must be stripped out and pressure held at a stable, lowered setting.
Regulating clamp pressure on a pneumatic clamping fixture in a CNC machining cell, with the 40 um element stopping scale and condensate from reaching the clamp valve.
Size and port step up with required flow: this is the 600 size with a 1 in G thread, the largest in the range. Drain type is a real choice - differential pressure (as here, the default), automatic (A) for unattended draining, or manual (M) where you want operator control. Filter grade is 40 um standard; specify W for 5 um when finer filtration matters. Gauges come embedded square or external round, with MPa, psi or bar scales, and thread can be ordered in PT, G or NPT; a 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. 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 we do not quote a number. Send us your application details and we will confirm the flow from the datasheet on request.
K shows a reverse (check) valve is fitted, so air cannot flow back through the unit. C2 is the external round gauge with a psi scale. The thread on this unit is G (BSPP); PT is the standard thread and G or NPT are catalogue options to order.
