The AirTAC GFR60020MLF2GK AirTAC Filter Regulator G3/4 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 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 AirTAC GFR60020MLF2GK 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 has a G3/4 port, a manual-drain bowl in aluminium alloy, a 40 um filter element, the low-pressure regulator type, an embedded square gauge reading in psi, and a reverse/check valve fitted. Mounting bracket included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus drain, filter-grade, gauge and thread options to match the line. Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. 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. |
| (blank) | Filtering grade 40 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. |
| 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.

Conditions and regulates the compressed air feeding spray guns and air-assisted applicators on a paint line, with the manual drain letting an operator clear accumulated water from the aluminium bowl at the start of each shift.
Sits ahead of the solenoid valve manifold on a packaging machine, filtering water and particulate out of the supply air and holding a steady downstream pressure so the valves and actuators see consistent supply.
Feeds the air cylinders that raise gates and stoppers on a bottling-plant conveyor, filtering the plant air and regulating it to the pressure the gate circuit was set up for, with the reverse/check valve holding the downstream side.
Size and port step up together: 200 through 600 cover 1/8 to 1 inch ports, so choose the size whose flow curve covers your demand. This unit is the low-pressure regulator type; its exact regulation range is not published, so confirm it against your set pressure before ordering. Drain choices are differential-pressure (default), automatic (code A) or manual (code M, fitted here). Filter grade is 40 um standard, with 5 um (code W) where finer filtration is needed. The embedded square gauge reads psi; MPa and bar scales and an external round gauge are options. Thread is G (BSPP); PT is the standard and NPT is an order option. Flow is published as curves, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for this unit is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - port size, line pressure and expected demand - and we will confirm the datasheet flow curve and correct sizing before you order.
This configuration carries code M, meaning the aluminium bowl is drained by hand at intervals. If you would rather not drain it manually, the same size is available with an automatic drain (code A) or the default differential-pressure drain - tell us your installation and we will confirm the right drain type.
