The AirTAC GFR600C20ALJC1TK 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 AirTAC GFR600C20ALJC1TK is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has NPT3/4 ports, a 40 um filter element, an automatic drain, the low-pressure regulator type, a round MPa pressure gauge and a built-in reverse (check) valve, and it is supplied without a mounting bracket. The aluminium alloy bowl suits this largest frame in the range; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. GFR filter regulators are published in four sizes - 200, 300, 400 and 600 - with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, PT, G (BSPP) or NPT threads, and optional brackets. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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.

Point-of-use conditioning for pneumatic clamps on a machining-centre fixture that runs at reduced pressure, where the low-pressure regulator type holds the setting and the built-in check valve protects against a supply dip.
Filtered, regulated air for the drive cylinders of a case-sealing station on a packaging conveyor line, with the automatic drain clearing condensate from the 3/4-inch drop without manual attention.
Conditioning the compressed-air feed to a laboratory pick-and-place module that needs clean, low-pressure regulated air at its 3/4-inch supply connection.
Size the unit by the port and flow step: 200, 300, 400 and 600 move up through ports 1/8 to 1 inch, so pick the size whose flow curve covers your demand - we can check the curves against your application before you order. Decodable choices on this family: drain type (differential-pressure standard, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale (embedded square or external round; MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket. This unit carries the low-pressure regulator type; its adjustment range is not published in our sheet, so confirm it with us. No rated flow number is quoted because the catalogue publishes flow only as curves.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the datasheet curve figures for your application before you order.
The A in this code specifies an automatic drain, which discharges condensate from the bowl without manual attention. The GFR600 series is also available with a manual drain, or with the differential-pressure drain that is the standard default; tell us which you prefer when ordering.
