The AirTAC GFR60020MLC2T AirTAC Filter Regulator NPT3/4 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 GFR60020MLC2T is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit has 3/4 in NPT ports, a manual drain bowl in aluminium alloy, 40 um standard filtration, and a low-pressure regulator type fitted with an external round gauge scaled in psi. A mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filter grades, standard or low-pressure regulator types, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for your application on request.

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). |
| C | Gauge shape: Round. 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. |
| 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.

Feeds filtered, regulated air to clamping fixtures and workholding cylinders that hold at a low set pressure, with the psi gauge giving the operator a direct reading at the fixture manifold.
Sits at the drop to a spray booth or coating applicator, removing water and pipe-scale from the shop air supply while the low-pressure regulator holds the gentle delivery pressure the process needs.
Protects low-pressure actuation circuits on packaging and conveying machinery, filtering the incoming compressed air and holding a stable low set pressure for gentle product-handling motion.
Start with the port step: this unit is size 600 with 3/4 in NPT ports, the largest size in the series, so check it against the pipe size and air demand of your circuit. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type (this unit is manual; automatic and differential-pressure drains are available on other codes), filter grade (40 um standard here, 5 um with the W code), regulator type (this is the low-pressure type), gauge (round, psi scale here; embedded square gauges and MPa/bar scales are options), thread (PT is the standard, G and NPT are order options), and bracket (included on this code; J codes omit it).
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 rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
In the code GFR60020MLC2T, the M sets a manual drain (you drain the bowl by hand; automatic and differential-pressure drains are available on other codes), and C2 fits the optional external round gauge scaled in psi. The embedded square gauge is the standard fitting, with MPa, psi and bar scales available.
