The AirTAC GFR600C20ALJNWT AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20ALJNWT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 3/4 in NPT port, a 5 um filter element (the finer W grade, against the 40 um standard), an automatic drain on the metal bowl (aluminium alloy at size 600) and the low-pressure regulator type. No gauge is fitted (code N) and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge options 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 figures from the datasheet 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.

Filtering and regulating the air to clamp and hold-down cylinders on a stamping or press line, where the 5 um element keeps particulate out of the seals and the automatic drain clears condensate without operator rounds.
Conditioning air for carton-forming and case-sealing cylinders on a packaging conveyor, with the 3/4 in NPT port feeding a main drop and the low-pressure regulator holding a gentle setting for delicate gripper action.
Supplying filtered, regulated air to a bank of directional control valves on an automated assembly machine, keeping water and 5 um-and-larger particles away from the valve spools while the automatic drain handles condensate.
Size and port set the flow capacity: the 600 frame with its 3/4 in port is the largest step in the GFR range, so match it against your air demand before ordering. This unit is already specified with the 5 um W-grade element and an automatic drain, which empties the bowl without operator attention; the alternatives are a manual drain or the differential-pressure default. The L code makes this the low-pressure regulator type rather than the standard unit - the standard type adjusts 0.15-0.9 MPa with automatic or differential-pressure drains, while this variant's range is not published, so confirm it with us.
Other decodable choices are the thread (PT is the standard; G and NPT are order options - this unit is NPT), the gauge (none fitted here; an embedded square gauge or an optional external round gauge with MPa, psi or bar scales is available on regulator units) and the bracket (not included with the J code). Flow is published as curves, not a single rating, so 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 GFR series as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your application and we will confirm the flow figures from the datasheet, including how the 5 um element and the low-pressure regulator type sit on the curve, before you order.
The N in the code means no gauge is supplied. Filter-regulator units in this family can carry an embedded square gauge or an optional external round gauge, with MPa, psi or bar scales. If you need a gauge, order the variant with the gauge code in place of this N-suffix model.
