The AirTAC GFR60025MLF1TK 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 GFR60025MLF1TK is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This configuration is the size 600 unit with a 1 in NPT port, a manual-drain bowl in aluminium alloy, the standard 40 um filter element, the low-pressure regulator type, an embedded square gauge scaled in MPa, a reverse/check valve fitted, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm figures against your application - we supply the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure 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. |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Mounted at a 1 in main drop from the compressor room, this unit cleans the shop air and holds a set header pressure for the tools and actuators fed downstream.
Feeding the large-bore pneumatic cylinders that index and push cases along a bottling conveyor, filtering condensate and scale out of the supply while regulating the pressure to the actuators.
Supplying an air-operated double-diaphragm pump on a chemical transfer skid, where the filter removes water and debris from the air line and the regulator sets the pump's supply pressure.
Step through the GFR sizes 200 to 600 and ports 1/8 in to 1 in to match the flow your line needs; we confirm sizing against the published curves before you order. Drain choice is differential-pressure (default), automatic (A) or manual (M) - this unit is manual, so the bowl is emptied by hand during routine checks. Filter grade is 40 um standard or 5 um with code W. The gauge here is the embedded square type on an MPa scale; psi or bar scales and an external round gauge are options. Thread is PT as standard with G and NPT as orderable options - this unit is NPT. A bracket is included; specify code J to omit it.
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 here. Tell us your line conditions and we will confirm the flow from the datasheet on request before you order.
Manual drain (code M) means the bowl is emptied by opening the drain valve by hand during routine checks. The same GFR600 size is available with an automatic drain (code A) or the default differential-pressure drain - tell us which you prefer and we will quote the matching code.
