The AirTAC GFR60020ALJF1T AirTAC Filter Regulator 3/4 in NPT 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020ALJF1T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, uses the standard 40 um filter element, and carries an automatic drain so collected condensate is expelled without manual attention. It is a low-pressure regulator type with a fitted embedded square gauge scaled in MPa, and no mounting bracket is included.
This is a genuine AirTAC part from the GFR600 series, the largest size in the G-series line, with an aluminium alloy bowl. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| (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.

Installed at the take-off point of a large compressed-air distribution header, it filters water and scale from the main supply and holds a steady low regulated pressure for a production hall's downstream circuits.
Feeding a heavy-duty pneumatic press or clamping line, it conditions the 3/4 in supply air and lets the operator set the working pressure that the cylinders and valves actually see.
Mounted on an actuated-valve skid, it cleans the instrument air and regulates it to the pressure the actuators are specified for, with the automatic drain keeping condensate out of the control loop.
Size 600 with 3/4 in ports is the top of the G-series range, so step up to it when your line's required flow sits beyond what smaller 200-400 bodies can pass - we will confirm the flow curve against your demand on request. The automatic drain suits unattended or hard-to-reach installations; if you prefer scheduled manual draining, a manual-drain variant exists in the family. The standard 40 um element covers general plant air; a 5 um element (code W) is available when finer filtration is needed.
This unit is the low-pressure regulator type, so match it to circuits that run below standard plant pressure - we will confirm the exact adjustment range from the datasheet on request. The fitted square gauge reads in MPa; external round gauges with MPa, psi or bar scales are optional. Thread here is NPT as ordered; PT is the standard and G (BSPP) is also a catalogue option. No bracket is included with this code.
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 this series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet curve on request before you order.
The A in the code sets the automatic drain, which expels collected condensate by itself - useful where the unit is mounted out of reach. The L sets the low-pressure regulator type, intended for circuits that operate below standard plant pressure; we confirm the exact adjustment range from the datasheet on request.
