The AirTAC GFR600C20F3TK AirTAC Filter Regulator NPT3/4 with Gauge is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 GFR600C20F3TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, the standard 40 um filtration grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge scaled in bar so the set pressure can be read at a glance. A reverse/check valve is fitted to hold downstream pressure if the upstream supply is lost, and a mounting bracket is included. The size 600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and reverse/check valve. Flow is published in the catalogue as curves rather than a single rated figure, so if you need a specific flow or datasheet figure for this model, ask us and we will confirm it 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.

Clean, regulated air feeding tool-change cylinders and clamping fixtures on a machining centre, with the check valve holding the clamp circuit if shop air drops.
Conditioned air for carton-forming and case-sealing pneumatic actuators on a packaging line, keeping water and debris out of the valve bank downstream.
Regulated supply to pusher and divertor cylinders along a conveyor system, with the bar-scale gauge letting line staff verify set pressure at the drop.
The GFR600 is the largest frame in the GFR range, with a 3/4 in port suited to higher-flow branch lines; step up or down through sizes 200/300/400/600 to match the port and flow your line needs. Drain choice matters: the differential-pressure drain on this unit needs no manual attention, while automatic (code A) and manual (code M) versions are available. Filtration is 40 um as standard here; choose the W suffix if your application needs 5 um. The square gauge on this unit reads in bar; MPa and psi scales are the alternatives, and an external round gauge is optional. Thread is NPT on this unit; PT is the standard and G is also offered. A reverse/check valve (K) is fitted, and a mounting bracket is included.
Because flow is published as curves and not as a single rated number, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves in the catalogue, not as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. The drain on this unit is the differential-pressure type: condensate collected in the aluminium alloy bowl is discharged automatically when the pressure differential across the filter element is sufficient, with no manual draining needed.
