The AirTAC GFR60020MLJC1TK 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 AirTAC GFR600-20-T is a filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This 600-size unit has 3/4 in NPT ports, a manual drain on an aluminium alloy bowl, the 40 um standard filter element, and the low-pressure regulator type for circuits that run at reduced set pressures. It is supplied with an external round pressure gauge on an MPa scale and a reverse/check valve fitted, and no mounting bracket.
This is a genuine AirTAC part. The GFR family is offered 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 (code W) filter grades, gauge styles and scales, and bracket options. Flow is published as curves rather than a single rating, so ask us to 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeding light-duty clamping and forming cylinders on a press line that runs at reduced set pressure: the regulator holds the downstream setting while the 40 um element keeps water and pipe scale out of the direction valves.
Point-of-use preparation for carton-sealing and wrapping machines on a packaging line: one body filters the air and sets the working pressure, and the manual drain is emptied during scheduled changeover.
On plant-air branches where oil mist or vapour in the line makes a polycarbonate bowl a poor choice, the 600-size aluminium alloy bowl is the safer option; the fitted reverse/check valve blocks reverse flow in the circuit.
Size the unit by port and flow: 600 is the largest GFR size, here with 3/4 in NPT threads (PT is the standard thread; G and NPT are catalogue options to order). The drain on this code is manual, so plan a routine blow-down; automatic and differential-pressure drains are available on other codes. The filter element is the 40 um standard grade, with 5 um available as code W. The gauge is the external round type on an MPa scale; the embedded square gauge and psi or bar scales are also offered. The L in the code marks the low-pressure regulator type, intended for reduced set pressures - ask us to confirm the exact adjustment range on request. No mounting bracket is included with this code. Because flow is published as curves, not a single rating, ask us to check 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing against the manufacturer datasheet on request.
A manual drain means the collected water is expelled by hand, which suits lines that are walked regularly; automatic and differential-pressure drains are available on other codes. The L in the code marks the low-pressure regulator type, intended for reduced set pressures - the exact adjustment range is not published, so ask us to confirm it for your setting.
