The AirTAC GFR600C20JC2WK AirTAC Filter Regulator 3/4 in PT 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 GFR600C20JC2WK is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a PT3/4 port (PT thread standard), a fine 5 um filtering element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and a round pressure gauge reading in psi. A built-in check valve lets downstream air hold when upstream supply is lost, and the unit ships without a mounting bracket. At size 600 the bowl is aluminium alloy, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the range you can order manual or automatic drains instead of the differential-pressure type, a 40 um standard element instead of this 5 um one, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures against 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.

Point-of-use conditioning ahead of spray booths and air-driven paint equipment, where the 5 um element and a steady regulated pressure help protect finish quality on the line.
Filtered, regulated air for the cylinders and air jets on a carton-forming and sealing conveyor, with the check valve holding downstream pressure if the main supply dips.
A main-air drop feeding multiple valves and tools on a CNC or machining cell, using the 3/4 in PT connection and psi gauge for straightforward panel integration.
The real choices in this family are all decodable from the code. Step up through sizes 200, 300, 400 and 600 (ports 1/8 in to 1 in) to match the pipe and the air demand of the line - the 600 size with its 3/4 in port sits at the top of the range for higher-demand mains. Choose the drain: differential-pressure (this unit) bleeds condensate on pressure differential, automatic drains continuously, and manual needs a routine drain visit. Choose the element: 40 um is the standard grade; this unit carries the finer 5 um grade (code W) for downstream equipment that needs cleaner air. Gauges come as an embedded square gauge or an external round gauge (this unit: round, psi scale) with MPa, psi or bar scales. Threads are PT as standard with G (BSPP) and NPT available to order, and a bracket is optional (this configuration has none).
One honest note on sizing: AirTAC publishes flow for the GFR series 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 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 performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application and air demand and we will confirm the sizing against the datasheet on request before you order.
The W in the model code orders the optional 5 um filtering element in place of the 40 um standard grade, for finer water and particulate removal ahead of sensitive equipment. The K orders a built-in reverse (check) valve, which lets downstream air hold when the upstream supply is interrupted. Both are standard catalogue options on the GFR family.
