The AirTAC GFR60025C3T AirTAC Filter Regulator 1 in NPT 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 GFR60025C3T is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit carries a 1 in NPT port, a 40 um standard filter element, a differential-pressure drain that bleeds condensate as flow passes, and a round pressure gauge reading in bar. The bowl on size 600 units is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT, G or NPT, manual or automatic drain variants, a 5 um element option, and gauge or no-gauge builds. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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. 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.

| 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)). |
| (blank) | Standard 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Installed at a 1 in distribution drop in a factory air ring main, it cleans the supply of water and scale and holds a steady header pressure for every machine tapped downstream.
Feeding a bank of quarter-turn pneumatic actuators on a process skid, it keeps actuator supply pressure fixed so valve stroking stays consistent across the line.
Serving the air supply to a pneumatic press or clamping station, it strips condensate before the cylinders and regulates working pressure to the setpoint the tooling was designed for.
Size 600 with a 1 in NPT port sits at the top of the GFR range, so step up or down only if your line flow genuinely demands it - the port step runs 1/8, 1/4, 3/8, 1/2, 3/4 and 1 in across sizes 200 to 600. Drain choice matters: the differential-pressure drain on this unit is maintenance-light for steady demand, while automatic or manual drain variants suit intermittent or supervised duty. The 40 um element is standard; specify W for the 5 um grade if downstream equipment needs finer filtration. The round bar gauge is fitted here; embedded square gauges and MPa or psi scales are the other catalogue options. NPT is ordered with the T suffix, PT is the standard thread, and G is also available.
Because flow is published as curves rather than a single rated figure, send us your application details 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line flow and pressure conditions and we will confirm the datasheet figures for this exact unit on request.
With no drain letter in the code, this GFR60025C3T carries the differential-pressure drain, which expels condensate automatically as air flows through - no operator attention. AirTAC also offers automatic (A) and manual (M) drain variants in the same size if your duty cycle or maintenance routine suits those better.
