The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 PT, 5 um, Auto Drain 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 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 GFR600-20 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 600-size unit carries a 3/4 in PT port, a 5 um filter element (finer than the standard 40 um), an automatic drain that ejects condensate without manual attention, a fitted reverse (check) valve, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). The bowl on this size is aluminium alloy, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT, G and NPT threads, with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, and a choice of gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm figures against your application - we supply the datasheet 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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.

| 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)). |
| (blank) | Standard 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

| 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.

Point-of-use conditioning on 3/4 in branch lines feeding impact wrenches, nutrunners and clamping fixtures, keeping supply air dry and pressure steady across a shift.
Clean, regulated air for tool changers, part clamps and air-blast chip clearing, where the 5 um element helps protect sensitive pneumatic components.
Conditioned air for carton sealers, case erectors and actuated diverters, with the check valve helping hold downstream pressure during upstream fluctuations.
Size the unit by port and expected flow: this 600 frame carries a 3/4 in PT port, the largest step in the GFR range. Choose the drain to match your maintenance practice - automatic here, versus manual or differential-pressure. The 5 um element (code W) suits finer air-quality needs; 40 um is the standard grade. The embedded square gauge is set to psi, with MPa and bar scales available and an external round gauge as an option. PT is the standard thread, with G and NPT as order options, and this configuration omits the mounting bracket. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for this series is published as curves, not as a single rated figure, so we do not quote a number. Tell us your application and expected air demand and we will confirm the sizing against the AirTAC datasheet on request.
The code A in GFR60020AJF2WK specifies the automatic drain, which ejects condensate without manual attention. The GFR family is also available with a manual drain (code M) or the differential-pressure drain (blank code), so you can match the drain to your maintenance routine.
