The AirTAC GFR60020C2WGK AirTAC Filter Regulator G3/4 5um psi 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 GFR60020C2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration is built around a G3/4 (BSPP) port, a 5 um filter element for finer particle capture than the standard 40 um grade, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough - no manual draining in normal service. The 600-size bowl is aluminium alloy, and this unit ships with a round external gauge reading in psi, a built-in reverse/check valve that holds downstream pressure if the supply drops, and a mounting bracket included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, optional 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and G, NPT or PT threads. Regulation range for this configuration is 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C, non-freezing. 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 0.15 - 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.

Drops feeding a whole production bay from a 3/4 in ring main get one unit doing both jobs: 5 um filtration strips water and pipe-scale before it reaches every branch, while the regulator holds a steady header pressure for the whole bay.
A machining centre's pneumatic tool-change and clamping circuits need clean, stable air at a fixed setting. The 5 um element protects the machine's solenoid valves from particles, the psi gauge lets setters verify the regulated pressure at a glance, and the check valve holds the circuit if the shop supply dips mid-cycle.
Carton formers and case sealers run many small air cylinders off a single 3/4 in drop. A filter regulator at the line inlet keeps moisture and grit out of the cylinder seals and gives the line one pressure setting, with the differential-pressure drain handling condensate without operator attention.
Start with the port step: this unit is size 600 with a G3/4 port, the largest in the GFR range - step down to GFR200/300/400 if your line runs smaller ports and lower air demand, and size against the published flow curves rather than a single number. Filtration choice is 40 um standard versus the 5 um element fitted here (code W); choose 5 um when downstream valves, cylinders or instruments need finer protection. Drain options are differential-pressure (fitted here), fully automatic, or manual - the latter widens the regulation range down to 0.05 MPa. Gauge scales are MPa, psi or bar, with an embedded square gauge standard or an external round gauge as fitted on this unit. Thread is G (BSPP) here; PT is the standard catalogue thread with G and NPT available as order options. A reverse/check valve (code K) and a mounting bracket are both included on this configuration. Because flow is published as curves and not a single rated figure, send us your air demand 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 l/min or SCFM figure here. Tell us your line pressure, regulated setpoint and air demand, and we will confirm the flow from the datasheet curves for this exact 3/4 in configuration before you order.
The W in the code specifies the optional 5 um filter element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. K specifies a built-in reverse/check valve, which holds downstream pressure if the upstream supply fails. The drain is differential-pressure type: it discharges collected condensate automatically when the pressure differential across the bowl is sufficient, so no manual draining is needed in normal service.
