The AirTAC GFR60025MJF1TK AirTAC Filter Regulator NPT1 1in 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 GFR60025MJF1TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the size 600 unit with 1 in NPT ports, a manual drain bowl in aluminium alloy, the standard 40 um filter element, a fitted embedded square gauge scaled in MPa, a built-in reverse (check) valve, and no mounting bracket. It handles a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -5 to 70 C (non-freezing), with a standard regulation range of 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus choices of drain type, 40 um or 5 um filtration, gauge style and scale, and reverse valve. Flow figures 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 0.05 - 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.

|---|---|
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeding filtered, pressure-regulated air to spray guns and air-assisted applicators on a paint line, where the 1 in ports suit a main supply drop and the manual drain lets an operator bleed accumulated water at shift start.
Supplying regulated air to cylinders and air-driven diverters on a packaging or bottling conveyor, with the check valve holding downstream pressure if the main supply is interrupted mid-cycle.
Conditioning and regulating supply air on a machine-builder's pneumatic test bench, where the MPa square gauge gives the operator a direct set-point readout and the 40 um element protects sensitive test fixtures.
Size and port are the first decodable choice: this is the largest GFR size (600) with 1 in NPT ports, suited to lines with high air demand; smaller sizes 200-400 step down in port and capacity. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. Other real choices on this family: manual drain (as coded here) versus automatic or differential-pressure drain; 40 um standard filtration versus the 5 um W element; square embedded gauge versus optional external round gauge, with MPa, psi or bar scales; PT standard thread versus G or NPT options; and bracket versus no bracket (J, as coded here). The K code adds a reverse (check) valve, useful where upstream supply may be lost and downstream pressure must be held.
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 one number. Tell us your application and we will confirm the relevant datasheet flow figures on request before you order.
The M in the code selects the manual drain: an operator opens it to release collected condensate, unlike the automatic or differential-pressure drain options. At size 600 the bowl is aluminium alloy; only the smaller 200/300/400 sizes use a polycarbonate bowl. The code also carries J (no bracket), F1 (square gauge, MPa scale) and K (reverse/check valve fitted).
