The AirTAC GFR60020C2WTK AirTAC Filter Regulator NPT 3/4 in 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 GFR60020C2WTK is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built for a 3/4 in NPT port, carries the fine 5 um filter element (code W), drains condensate by differential pressure, and is fitted with an external round gauge scaled in psi. A reverse/check valve (code K) is built in, and the size 600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, gauge scale options in MPa, psi or bar, and PT, G or NPT threads. 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.

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

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.

Installed at the take-off point of a factory compressed-air main, it cleans water and particulate from the 3/4 in supply line and holds a steady regulated pressure for the downstream air circuit.
Feeding cylinders and air actuators on a packaging or conveyor line, the 5 um element protects valves from dirt and water while the regulator keeps actuator pressure consistent through the shift.
Mounted on the air-preparation panel of an OEM machine, the combined filter regulator saves panel space over separate units, and the built-in check valve holds the set pressure against backflow.
Step up or down through the GFR sizes (200/300/400/600) against the port and flow your line needs - this unit is the 600 size with a 3/4 in NPT port. Choose the filter grade to match the air quality your equipment tolerates: 40 um standard or 5 um fine (this unit carries the 5 um element). Drain type matters: differential-pressure (fitted here) drains with flow, automatic drains unattended, manual needs a routine. Gauge scale is your call (MPa, psi or bar - this unit is psi), and a reverse/check valve can be specified where backflow must be blocked. Thread is PT as standard with G and NPT as order options; a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing and datasheet figures with you 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 family as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code GFR60020C2WTK selects the fine 5 um filter element instead of the 40 um standard, for applications that need cleaner air. The K selects a built-in reverse/check valve that blocks backflow through the unit. Both are order-time choices on the GFR series, along with drain type, gauge scale and thread.
