The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 in PT 5 um psi gauge is a genuine G-series filter regulator: water separation, 5 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 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 600-size unit has a 3/4 in PT port, a 5 um filter element (code W), a manual drain, and a round pressure gauge reading in psi. It is the low-pressure type, rated for a maximum inlet pressure of 1.0 MPa (145 psi) and -5 to 70 C (non-freezing), with an aluminium alloy bowl. No mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200 to 600 with ports from 1/8 to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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". |
| 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Feeds actuators and air tools on circuits that run below standard line pressure, filtering water and particles while holding a reduced downstream setting.
Installed at branch lines in a factory air network to clean and regulate air before it reaches a work cell, machine section or local distribution header.
Prepares the air feeding clamps, cylinders and purge points on machining equipment where a 3/4 in supply and fine 5 um filtration are specified.
Size and port step up from 200 to 600 as flow demand grows; this unit sits at the 600 size with a 3/4 in PT port. Drain choices are differential-pressure (default), automatic (A) or manual (M) - this unit is manual, so drain it as part of routine checks. Filter grade is 40 um standard or 5 um with the W code; this one carries the 5 um element. Gauges come as an embedded square gauge or an external round gauge with MPa, psi or bar scales - here it is a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available to order; a bracket is optional and not fitted on this unit. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 the GFR series as curves rather than a single rated figure, so no one number applies. Tell us your application and we will confirm the flow data from the datasheet before you order.
The L code marks the low-pressure regulator variant, intended for circuits that run below standard line pressure. The exact adjustment range for this variant is not published on the catalogue sheet we use; ask us and we will confirm it on request.
