The AirTAC GFR600-20G 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 carries a G3/4 (BSPP) port, a 40 um standard filter element, and an automatic drain that expels collected condensate without manual attention. It is the low-pressure regulator type, fitted with an embedded square gauge scaled in psi and a reverse/check valve, and it ships without a mounting bracket. The aluminium alloy bowl is specific to the 600 size, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, a 5 um (code W) element alternative, gauge scale options in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |
| 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.

Drops filtered, regulated air into a G3/4 distribution header feeding case packers and wrap machines, with the automatic drain handling condensate on a line that runs unattended across shifts.
Sits at the drop feeding air presses and clamping fixtures where the low-pressure regulator type holds a lower working pressure for the clamping stage, with the check valve holding downstream conditions.
Prepares the air feeding conveyor blow-off and air-knife manifolds, removing water and scale before the nozzles while the psi-scaled square gauge gives operators a direct line-side pressure readout.
Choose the GFR size by port and required flow: this 600 unit steps up to G3/4, the largest port in the family, for high-consumption lines. Drain choice matters in duty terms: the automatic drain fitted here suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the alternatives in the series. The 40 um element is the standard grade; specify 5 um (code W) if finer particulate removal is needed. Gauge scale is set here to psi; MPa and bar scales are available. Thread is G (BSPP) on this code; PT is the standard thread and NPT is an order option. This unit has no mounting bracket (code J).
Note that this is the low-pressure regulator type; its exact regulation range is not published in the material we hold, so confirm it with us before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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, downstream demand and port size, and we will confirm the flow from the datasheet on request before you order.
The A code fits an automatic drain, which ejects collected condensate by itself instead of waiting for a manual or differential-pressure cycle - useful on elevated or infrequently visited installations. The L code selects the low-pressure regulator type; its exact regulation range is not published in our material, so confirm it with us on request.
