The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 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 GFR600-20 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is built with 3/4 in NPT ports, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, and a manual drain bowl. Because it is the 600 size, the bowl is aluminium alloy. A round pressure gauge with a bar scale is fitted, and a reverse/check valve (code K) is installed to hold downstream pressure if the upstream supply drops. No mounting bracket is included with this configuration.
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, and options for drain type, filter grade, gauge style and scale, thread form and check valve. Flow is published as curves rather than a single rating, 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. |
| 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.

Feeds filtered, regulated air to the pneumatic clamps and tool-change cylinders of a CNC machining cell, with the 5 um element protecting fine-seal actuators from particulate carryover.
Sits at the drop point of a packaging conveyor's air line, conditioning and regulating the supply to diverters, pushers and bag-seal cylinders along the line.
Prepares the air feeding the filler and capper valve manifolds on a bottling line, holding a steady set pressure so fill-timing valves repeat consistently through the shift.
Start with the port and size step: GFR units come in sizes 200, 300, 400 and 600, and the 3/4 in port of this 600 model suits higher-flow circuits - match the size step to the flow your line needs. Drain type is a real choice: differential-pressure (default), automatic, or manual as fitted here; manual drain means someone opens the bowl drain periodically, and with a manual-drain unit the adjustment range is 0.05-0.9 MPa (7-130 psi). Filter grade is 40 um standard or 5 um with code W, as on this unit. Gauge scale can be MPa, psi or bar (bar fitted here), and thread is PT as standard with G and NPT as order options - this unit is NPT. A bracket can be ordered if you want panel mounting; this configuration ships without one.
Because flow is published as curves and not as a single rated figure, we cannot quote a number here - send us your application details and we will confirm sizing against the datasheet 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 number, so we do not quote a figure here. Tell us your line pressure, set pressure and the equipment you are feeding, and we will confirm the sizing from the datasheet curves before you order.
The M in the code means the bowl is drained by hand rather than by a differential-pressure or automatic drain, so an operator opens the drain periodically to remove collected water. With a manual-drain GFR unit the regulator adjustment range is 0.05-0.9 MPa (7-130 psi). If you would rather not schedule manual draining, the same size is available with an automatic drain.
