The AirTAC GFR600C20MLJC2TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20MLJC2TK is an AirTAC GFR600 filter regulator: a 600-size unit that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, the standard 40 um filter element, a manual drain on the aluminium alloy bowl, a low-pressure type regulator, a round gauge reading in psi, and a reverse (check) valve fitted. It is supplied without a mounting bracket. 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. The GFR filter-regulator family is available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, gauge and scale choices, and bracket options. Flow for this series is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure for 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.

Filtering and regulating the air feeding a machining centre's tool-clamp and tool-change cylinders, holding a steady low set point so clamping pressure does not drift over a shift.
Conditioning the air that drives pick-and-place and sealing cylinders on a carton packaging line, with the manual drain emptied during scheduled line-cleaning stops.
A filtered, regulated air drop at a bench press or riveting station in a fabrication shop, where the fitted check valve holds the downstream setting if supply pressure dips.
Size the unit by port and flow: this is the 600 size with a 3/4 in NPT port, the largest step in the GFR range (200, 300, 400, 600), chosen when your line needs the bigger port. The drain here is manual (code M): condensate is drained by hand from the aluminium alloy bowl, so plan it into a maintenance routine; automatic and differential-pressure drains are alternative codes in this family. Filtration is the standard 40 um element; specify W for the 5 um grade if downstream equipment needs finer filtration. The regulator is the low-pressure type (code L); its exact setting range is not published in the sheet we work from, so confirm it with us against your set point. The fitted gauge reads in psi; embedded square gauges and MPa or bar scales are the other options. Thread is NPT here, with PT as the standard and G (BSPP) also an order option, and no mounting bracket is included (code J).
Flow for this series is published as curves, not as a single rated figure, 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 this series as curves, not as a single rated number, so we do not quote a figure. Tell us your application and operating pressure and we will confirm the flow from the datasheet on request before you order.
This unit carries the L code, so the regulator is the low-pressure type rather than the standard version. The exact setting range for this variant is not published in the sheet we work from, so ask us to confirm it against your set point before ordering.
