The AirTAC GFR60025MLF2WG AirTAC Filter Regulator G1 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 GFR60025MLF2WG is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit carries a G1 (1 in) G-thread port, a 5 um filter element (the finer of the two catalogue grades), a manual drain bowl in aluminium alloy, an embedded square gauge with psi scale, and the low-pressure regulator type. 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 is published in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, 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. |
| (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. |
| G | G (BSPP) 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.

Installed on the 1 in main air feed to a stamping or forming press, this unit filters moisture and fine particles from the plant air supply and holds a stable low regulated pressure to the press clutch and counterbalance circuits.
Mounted at the drop from a bottling plant's main header, the 5 um element protects the conveyor stopper and gate cylinders from water and debris, while the low-pressure regulator sets the gentle pressure those actuators need.
Fitted ahead of the jet and nozzle manifolds on weaving or spinning machines, this unit cleans the compressed air to 5 um and regulates it to the low working pressure the machine builder specifies, with the psi gauge giving operators a direct reading.
Size 600 is the largest step in the GFR range, with a G1 (1 in) port for the highest flow band in the family - match it against your line's air demand, and ask us to check the published flow curves against your application. This unit is already specified with the finer 5 um element, manual drain, square psi gauge, G thread and the low-pressure regulator type; if you need 40 um filtration, a different gauge scale (MPa or bar), PT or NPT thread, or an external round gauge instead of the embedded square one, those are catalogue options on the same series. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet figures before you order.
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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a flow number here. Send us your application - line pressure, required downstream pressure and the equipment being supplied - and we will confirm the datasheet flow figures for this size-600, G1 unit before you order.
The MLF2 code specifies a manual drain bowl: condensate collects in the aluminium bowl and an operator drains it by hand. This GFR600 unit is also available from the catalogue with automatic or differential-pressure draining if you would rather not rely on manual attention. With the 5 um element and low-pressure regulator type already fitted, the main remaining choices are gauge scale (this one reads psi) and thread (this one is G; PT and NPT are order options).
