The AirTAC GFR60020MLJC3TK 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 GFR60020MLJC3TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, a manual drain bowl in aluminium alloy, a low-pressure regulator type, a round pressure gauge with bar scale, and a built-in reverse (check) valve. No mounting bracket is 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 family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types, 40 um or 5 um filtration, gauge styles and scales. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing 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. |
| 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.

Feeding filtered, pressure-controlled air to spray booths and atomising headers on a finishing line, where the low-pressure regulator type and manual-drain bowl suit a supervised coating operation.
Supplying water- and particle-filtered instrument purge air to analytical or pilot-plant skids that run at low control pressures and read local gauges in bar.
Conditioning and regulating the main air feed entering a packaging machine's valve manifold, with the check valve holding the circuit if the upstream supply is interrupted.
Start with the port step: size 600 with a 3/4 in port sits at the top of the GFR range, so match it to the line size and the flow your circuit needs - we can check the published flow curves against your application before you order. This unit is the low-pressure regulator type, so confirm the control band suits your circuit; the exact range for the low-pressure version is not published and we confirm it on request. The manual drain means an operator opens the bowl drain periodically, which suits attended installations; ask about automatic or differential-pressure drain codes for unattended duty. The 40 um element is the standard grade - specify code W for 5 um where finer filtration is needed. The round gauge is fitted with a bar scale; square embedded gauges and MPa/psi scales are alternatives. Thread here is NPT; PT is the standard and G is also an order option. No bracket is included with this code.
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 as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your circuit needs and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: condensate collected in the aluminium bowl is released by opening the drain fitting, which suits installations that are checked regularly. The K adds a reverse (check) valve that blocks backflow through the unit. If you need automatic or differential-pressure draining instead, those are separate order codes in the same family.
