The AirTAC GFR600-25T 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25T is a filter regulator: filtration and pressure regulation combined in a single body, so one 1 in NPT connection both removes water and particulate from the compressed air and holds the downstream pressure where you set it. This configuration carries the standard 40 um filter element, a manual drain on the bowl, and a fitted round pressure gauge reading in bar. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi). Because this is the 600 size, the bowl is aluminium alloy rather than polycarbonate, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with automatic, manual or differential-pressure drains, a 5 um (W) element instead of the standard 40 um, alternative gauge styles and scales, G or NPT threads, and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 0.05 - 0.9 MPa (7 - 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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 filtered, regulated air from the 1 in main drop to the valve manifolds that run grippers and fill heads on a bottle-filling line, with the manual drain bled during shift changeover.
Supplying clean, regulated air to the stopper and pusher cylinders that divert cartons on a packaging conveyor, with the 40 um element keeping pipe scale and condensed water out of the valves.
Regulating supply pressure to pneumatic clamps on a machining-cell fixture, where the round bar gauge gives the operator a direct read of clamp circuit pressure at the cell.
Start with the port step: this code is the 600 size with a 1 in thread, the largest in the GFR range, so match it to your main-line pipe size and required flow. Next choose the drain: this unit is manual drain, meaning someone bleeds the bowl periodically; automatic or differential-pressure drain codes exist if you cannot rely on routine attention. The filter grade here is the standard 40 um; order the W code if the application needs 5 um. The gauge on this code is the external round type with a bar scale; embedded square gauges and MPa or psi scales are alternatives. Thread is NPT on this code (PT is the standard thread, G and NPT are catalogue options to order), and the J code means no mounting bracket is supplied. 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. 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 here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves on request before you order.
The M in the code GFR600-25MJC3T specifies a manual drain: condensate collected in the aluminium bowl is released by hand, which suits installations visited regularly. If the unit will sit unattended, the same 600 size can be ordered with an automatic drain (code A) or a differential-pressure drain (blank code) instead.
