The AirTAC GFR600C20C1WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20C1WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 600 unit carries a 3/4 in NPT port, the W-code 5 um filter element, and the differential-pressure drain, which opens on the pressure drop across the element and is the catalogue default drain type. A round pressure gauge scaled in MPa is fitted, a reverse/check valve holds the downstream setting if the supply is interrupted, and the aluminium alloy bowl is supplied with a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -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.

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.

Conditioning the air at paint-booth drops: the 5 um element removes water and particulate that would spoil finish quality, while the regulator holds a steady setting to the spray guns.
Feeding filtered, regulated air to the cylinders and grippers on a carton-forming and sealing conveyor, with the reverse/check valve holding the downstream setting if plant air is interrupted.
Supplying filtered, regulated air to workholding clamps and pallet-locating cylinders in a machining cell, where a stable downstream pressure keeps clamping repeatable.
Size and port are the first decision: the 200 to 600 steps run from 1/8 to 1 in, and the air demand of the circuit decides which step fits - we can check the published flow curves against your requirement before you order. This unit already carries the 5 um (W) element; the standard grade is 40 um, so the coarser element is the economical choice where fine filtration is not needed. Drain options are differential-pressure (fitted here), automatic (A) or manual (M). Gauge choices are the embedded square type or the external round type fitted here, scaled in MPa, psi or bar. Thread is NPT on this code; PT is the standard and G (BSPP) is also a catalogue option, and a mounting bracket is included.
Because AirTAC publishes flow as curves rather than a single rated figure, there is no one flow number to quote. Tell us your inlet pressure, set pressure and expected air consumption, and we will confirm the sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated figure, so there is no one number we can quote. Send us your inlet pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet before you order.
This code carries the optional W element, which filters to 5 um instead of the standard 40 um. Choose 5 um where downstream valves, cylinders or instruments are sensitive to fine particles or water carryover; 40 um is the economical choice for general plant air. Both grades are available across the GFR range.
