The AirTAC GFR60025MLC1TK AirTAC Filter Regulator NPT 1 in Low-Pressure 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 GFR60025MLC1TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built for 1 in NPT ports and carries a manual drain (M), the standard 40 um filter element, the low-pressure regulator type (L), a round pressure gauge reading in MPa (C1), and a reverse (check) valve (K). Because it is the 600 size, the bowl 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 ports from 1/8 in to 1 in, in PT, G (BSPP) or NPT thread, with differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, and gauge or no-gauge options. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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). |
| C | Gauge shape: Round. 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.

Filtering and regulating the shop-air feed that supplies large clamp and press actuators on a 1 in main header, with the manual drain emptied as part of routine shift checks.
Feeding filtered, low-pressure regulated air to large diaphragm or cylinder-actuated process valves on a water-treatment or chemical dosing skid, where the low-pressure type suits the modest set points involved.
Supplying clean, regulated air to fixture-clamping and part-blowing circuits on a machining centre, with the reverse (check) valve fitted in line as specified by the K code and the bracket used to mount the unit at the cell.
Step through the GFR sizes (200, 300, 400, 600) against the port and the flow your line needs; this code is the top of the range at 1 in NPT. Choose the drain to match maintenance practice: manual (this unit) for scheduled draining, automatic for unattended drops, or the default differential-pressure type. Pick the 40 um standard element or the 5 um W grade for finer protection, choose the gauge scale (MPa, psi or bar), and set the thread: PT is the standard, with G (BSPP) and NPT as catalogue options. Note the type code: this unit is the low-pressure type (L) rather than standard, and the K code adds a reverse (check) valve. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering - and for the low-pressure type, confirm the adjustment range against your set point the same way.
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 GFR-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, port size and application details, and we will confirm the datasheet flow curve and check the sizing with you before you order.
The M in GFR60025MLC1TK specifies a manual drain: condensate collected in the aluminium alloy bowl is drained by hand on a routine schedule. The GFR family is also available with an automatic drain or the default differential-pressure drain, and with a 5 um (W) element instead of the standard 40 um - tell us your preference when ordering.
