The AirTAC GFR60025MLNWTK AirTAC Filter Regulator NPT1 Low Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60025MLNWTK is a filter regulator: it removes water and particulate from compressed air and holds the downstream pressure at a set value, in one body. This size-600 unit has 1 in NPT ports, the 5 um filter element (the finer of the two published grades), a manual drain, and the low-pressure regulator type, so it suits circuits that run at reduced set pressures. No gauge is fitted in this configuration, a reverse/check valve is included, and the size-600 aluminium alloy bowl and mounting bracket are part of the unit. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 up to 1 in, and can be ordered with G (BSPP) or NPT threads instead of the PT standard, with automatic, manual or differential-pressure drains, a 40 um or 5 um element, a gauge, and a reverse valve. Flow for this unit 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. 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Conditioning the air that drives grippers and gate cylinders on a beverage bottling line: the 5 um element keeps water and debris out of the actuators while the regulator holds a steady low set pressure on the drop legs.
Feeding filtered, regulated air to clamp fixtures on a CNC machining cell, where the low-pressure type allows the clamp circuit to run at a reduced set pressure and the fitted check valve backs up the supply side.
Supplying clean, regulated air to hold-down clamps and divertor gates on a panel-saw or beam-saw line, with the 1 in NPT ports matching the shop main and the manual drain emptied during end-of-shift checks.
Size and port step up together: 600 is the largest published GFR size, and here it carries 1 in NPT ports, so match the port to your supply line and let us confirm the flow curve against your demand before ordering. The real choices encoded in this model are: drain type (manual here; automatic and differential-pressure drains are available on the family), filter grade (5 um here; 40 um is the standard element), gauge (none fitted; square and round gauges with MPa, psi or bar scales can be ordered), thread (PT is the AirTAC standard; G and NPT are order options, NPT on this unit), and the low-pressure regulator type. The exact regulation range of the low-pressure type is not published; we confirm it from the datasheet on request.
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 figure, so we do not quote a number here. Send us your inlet pressure and air demand and we will confirm the flow for this exact model from the datasheet before you order.
Yes. Manual drain means water collected in the aluminium alloy bowl is released by opening the drain by hand, which suits lines where checks are already part of the routine. The GFR600 size can also be ordered with an automatic or differential-pressure drain; tell us which you prefer and we will confirm the alternate model code.
