The AirTAC GFR600-20T AirTAC Filter Regulator 3/4 in NPT, 5 um 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 GFR600-20T is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and an external round pressure gauge reading in bar. The size-600 bowl is aluminium alloy, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR line is published in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard 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. |
| W | Filtering grade 5 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.

Filtered and regulated air at each paint-line drop keeps moisture and fine particles out of spray equipment, with the 5 um element and a bar gauge for the booth-side setting check.
A stable, filtered supply to pneumatic clamps and workholding on a machining centre, with the manual drain opened during scheduled maintenance of the cell.
Conditioned air to the cylinders on a carton-sealing station, where the regulator sets the pressure for consistent flap tucking and the bowl catches water before the valves.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this unit is the 600 size with a 3/4 in NPT thread (PT and G are the other catalogue thread options). The 5 um element suits air that feeds sensitive components; the standard grade is 40 um. The manual drain means an operator opens the bowl drain during checks - choose automatic or differential-pressure drain if you cannot visit the unit regularly. The round gauge here reads in bar; square embedded gauges and MPa or psi scales are the other options. A bracket can be added if you want panel fixing. 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant datasheet figures on request before you order.
This unit is ordered with a manual drain: the bowl is emptied by hand during routine checks, which suits attended installations. The catalogue also offers automatic and differential-pressure drain options on GFR units if the unit will be left unattended.
