The AirTAC GFR60025MLF2WT AirTAC Filter Regulator 1 in NPT 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 GFR60025MLF2WT is an AirTAC GFR filter regulator: filtration (water and particulate removal) and pressure regulation combined in one body, with a drain bowl but no lubricator. This 600-size unit has a 1 in NPT port, a 5 um filter element (grade W), a manual drain and the low-pressure regulator type, and includes the embedded square gauge scaled in psi plus a mounting bracket; no reverse/check valve is fitted. The bowl is aluminium alloy (standard at size 600), 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 range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G and NPT as order options, drain choices of differential-pressure, automatic or manual, filter grades of 40 um standard and 5 um optional, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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. |
| (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. |
| 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. |
| (blank) | No reverse-flow valve (the default). |
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 and regulating supply air to a clamping fixture on a machining cell, where the 5 um element helps keep water and particulate out of downstream valves and cylinders and the low-pressure regulator type suits low set-pressure clamping.
A single-body filter regulator feeding cylinder-driven diverters, pushers and gates on a packaging conveyor, with the manual drain opened during scheduled line checks and the psi-scaled gauge read directly by line staff.
Clean, regulated low-pressure air to spray guns in a finishing booth, where the 5 um grade supports finish quality and the aluminium alloy bowl with manual drain suits a booth-side daily draining routine.
The real choices in this family are the size and port step, the drain type, the filter grade, the gauge scale and the thread. Sizes run 200, 300, 400 and 600; this unit is the largest, with a 1 in NPT port for lines that need the biggest port step in the range. Choose the 5 um element (this unit, code W) where downstream equipment needs finer filtration than the 40 um standard. Manual drain (this unit, code M) means an operator opens the drain periodically; automatic and differential-pressure drains discharge condensate without that step. Thread is PT as standard, with G and NPT as catalogue options, and a mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and operating conditions and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code sets the manual drain: an operator opens the drain to discharge collected condensate. The alternatives are automatic drain (code A) and the differential-pressure drain (blank), which discharge without that step. Manual drain is the right choice where bowls are checked on a fixed maintenance schedule.
