The AirTAC AirTAC GFR60020MLC3TK 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 GFR60020MLC3TK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for 3/4 in NPT ports. This configuration is the low-pressure type with a 40 um filter element, a manual drain on the aluminium alloy bowl, a round pressure gauge reading in bar, and a reverse (check) valve fitted. Mounting bracket included. 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 series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, and square or round gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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. |
| 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.

Filters condensed water and particles from the mill air main, then holds a reduced, low-pressure setting for the spinning heads - the manual drain lets an operator bleed the bowl at shift start.
Conditions the air feeding the flap-fold and taping cylinders on a packaging conveyor: 40 um filtration ahead of a stable regulated supply, with the check valve holding the setting if the upstream feed dips.
Feeds filter and gate valve actuators on a treatment skid, with the round bar gauge giving operators a local pressure readout and the manual drain suiting a supervised, periodic blowdown routine.
Choose the size and port step against the air demand of your circuit: this unit is size 600 with 3/4 in NPT threads (PT is the standard thread; G and NPT are order options - here NPT is fitted). Drain options are differential-pressure (default), automatic or manual - this unit carries the manual drain, which you open by hand to release condensate. Filtration is 40 um standard; a 5 um element is available with code W. Gauge choices cover embedded square or external round gauges with MPa, psi or bar scales - this unit carries a round gauge reading in bar. A mounting bracket is included, and the reverse (check) valve is fitted. Flow is published as curves, not a single rating, so 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 GFR series as curves, not a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream demand and allowable pressure drop and we will confirm the flow from the datasheet for this size 600, 3/4 in unit before you order.
This unit's bowl has a manual drain: an operator opens it by hand to release collected condensate. It suits supervised installations with periodic checks. For unattended or high-condensate duty, the automatic or differential-pressure drain versions of the GFR600 are the usual choice - ask us to quote those instead.
