The AirTAC GFR60025MF2TK AirTAC Filter Regulator NPT1, 1 in 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 GFR60025MF2TK is a 600-size GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is decoded as a 1 in NPT port, manual drain, standard 40 um filtration, an embedded square gauge with psi scale, a fitted reverse/check valve, and the mounting bracket included. The manual drain means an operator opens the drain at the bottom of the bowl to discharge collected condensate, and the check valve holds downstream pressure if upstream supply is interrupted.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as standard and G or NPT as order options, manual, automatic or differential-pressure drains, and a 5 um (code W) filter grade where finer filtration is needed. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| 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.

Dropping from a 1 in plant air header into a packaging line, this unit filters bulk water and scale out of the supply and holds a set regulator pressure for the whole line, with the check valve holding the line up during brief upstream interruptions.
Feeding the cylinders and air actuators on a heavy conveyor or gate system, where a stable regulated pressure keeps stroke speeds consistent and the 40 um element stops pipe scale reaching the valve seats.
Conditioning the 1 in feed to a vehicle service bay or truck-mounted air circuit, where the manual-drain bowl is emptied as part of the daily check and the psi gauge gives operators a direct reading of set pressure.
Start with the port and size step: the 600 frame with a 1 in connection is the largest GFR size, so match it against the air demand of the line it feeds - because flow is published as curves, not a single rating, send us your required flow and we will confirm sizing against the datasheet before you order. On this unit the drain is manual, so plan for periodic draining by an operator; if you would rather not rely on that, automatic (A) and differential-pressure (blank) drain variants exist in the same family. Filtration here is the standard 40 um element; specify 5 um (W) only if the downstream equipment genuinely needs finer filtration. The fitted gauge is the embedded square type reading in psi; MPa or bar scales and an external round gauge are the other catalogue choices. Thread is NPT on this code, with PT standard and G available as options, and the bracket is included.
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, not as a single rated number, so we do not quote a figure here. Tell us the flow your application needs and we will confirm the datasheet curve for this 600-size, 1 in unit on request before you order.
The M in the code sets a manual drain: an operator opens the bowl drain to discharge collected condensate. The GFR family also offers automatic (A) and differential-pressure (blank) drains, and the regulation range differs by drain type - with a manual drain it is 0.05-0.9 MPa (7-130 psi). Choose the drain style that matches how the unit will actually be maintained.
