The AirTAC GFR60020ALJC2GK AirTAC Filter Regulator G3/4 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 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 GFR600-20G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a G3/4 (BSPP) port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type for circuits that run at reduced set pressures. It is fitted with an external round gauge scaled in psi and a reverse (check) valve, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) filter element option, gauge scale options, and PT (standard), G or NPT threads to order. Flow is published as curves rather than a single rating, so ask us to confirm the 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". |
| 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). |
| 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. |
| G | G (BSPP) 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.

A 3/4 inch branch feeding a packaging line that runs at reduced pressure: the GFR600 filters water and scale out of the header air and holds the lowered set pressure, while the automatic drain keeps condensate off the line without daily purging rounds.
On a machining cell where clamps and swing cylinders must not see full header pressure, this low-pressure type filter regulator sits at the drop, filtering the supply and regulating it down, with the psi gauge giving operators a direct reading at the fixture.
Installed upstream of a manifold feeding several take-offs, the unit cleans and regulates the whole branch in one body; the reverse (check) valve holds the downstream circuit against backflow if the upstream supply is interrupted.
Step up or down through the GFR sizes (200/300/400/600) so the port and flow capacity match the air demand of the circuit; this unit sits at the top of the range with a 3/4 inch G-threaded port. Choose the drain to suit access: automatic (this unit) for unattended duty, manual where you want controlled purging, or the differential-pressure default. The 40 um element is standard; specify code W for the 5 um grade if downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar) and the round external gauge are selectable, and PT is the standard thread with G and NPT as order options; brackets are optional (this configuration omits the bracket).
Because flow is published as curves rather than a single rated figure, and the low-pressure type's adjustment range is not stated as a single published value, ask us to confirm sizing and the regulation range against your set pressure and air demand 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 one number. Tell us your air demand and working pressure and we will confirm the sizing from the datasheet curves on request before you order.
The A in the code selects the automatic drain: collected condensate is expelled without manual attention, which suits unattended installations. The C2 selects the external round gauge scaled in psi; square embedded gauges and MPa or bar scales are available in other configurations.
