The AirTAC GFR60020MLF2WK AirTAC Filter Regulator 3/4 in PT 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 PT3/4" 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 GFR60020MLF2WK is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is built around a 3/4 in PT port, a 5 um filter element (W grade), a manual drain on the aluminium alloy bowl, and a low-pressure regulator fitted with an embedded square gauge reading in psi. A reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), with an operating temperature of -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, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulation, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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. |
|---|---|
| 20 | Port size PT3/4". 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. |
| (blank) | PT 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 and regulating the air feed to spray guns and booth equipment on a coating line, where the 5 um element helps keep water and particles out of the finish and the low-pressure regulator matches processes that run below standard shop pressure.
Filtering and regulating the supply to pneumatic cylinders and actuators on a packaging conveyor, with the manual drain emptied during scheduled changeovers and the psi gauge giving operators a direct pressure readout at the machine.
Feeding filtered, regulated air to tool changers, clamps and purge points on a machining centre, with the fitted reverse/check valve preventing backflow in the circuit and the aluminium alloy bowl suiting the shop environment.
Size and port set the air capacity: this unit is size 600 with a 3/4 in PT port, the largest step in the GFR range, which suits lines with substantial air demand. Choose the drain to match your maintenance routine - differential-pressure (the default), automatic (code A) for unattended draining, or manual (code M) as fitted here. Filter grade is 40 um standard or 5 um (code W) as fitted; pick 5 um where downstream equipment needs finer protection. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit reads psi. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Because rated flow is published as curves rather than a single figure, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures on request.
The M code in this model specifies a manual drain, so the aluminium alloy bowl is emptied by hand as part of routine maintenance. The same GFR600 size is also available with an automatic drain (code A) or the differential-pressure drain default if you prefer unattended operation.
