The AirTAC GFR600-20F2WGK AirTAC Filter Regulator G3/4, 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 differential-pressure 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 GFR600-20F2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G3/4 (BSPP) port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, an embedded square gauge reading in psi, and a reverse/check valve fitted. The maximum working pressure is 1.0 MPa (145 psi), the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
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 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow 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. 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.

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.

A 3/4 inch main feeding CNC machines and pneumatic clamps gets clean, dry air and a steady regulated pressure from one compact unit, with the psi gauge giving operators a direct readout at the drop.
Pneumatic cylinders and diverters on a packaging conveyor need consistent pressure to sequence reliably; the regulator holds the set point while the 5 um element protects valve spools from fine contamination.
Pilot-air supplies for automated process valves stay stable with the regulator, and the fitted check valve holds the manifold pressure through brief upstream dips so valve positions do not drift.
Size 600 with a G3/4 port is the largest step in the GFR range, so start there when your line volume points to a 3/4 inch connection - and confirm the match against the published flow curves before ordering. The 5 um element (code W) suits applications that need finer particulate capture than the 40 um standard; the differential-pressure drain bleeds collected condensate automatically as pressure differential builds, with no manual draining routine. The embedded square gauge here reads in psi, and MPa or bar scales are available instead if preferred. The G (BSPP) thread is a catalogue option - PT is the standard thread, and NPT can also be ordered. A mounting bracket is included, and the fitted check valve (code K) holds downstream pressure if the upstream supply drops. We confirm flow and datasheet figures on request, since flow is published as curves, not a single rating.
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 expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
W is the filter grade: this unit carries the 5 um element instead of the 40 um standard, for finer particulate removal. K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is interrupted. The code also decodes the square psi gauge (F2) and the G (BSPP) thread.
