The AirTAC GFR600C20MJF2TK AirTAC Filter Regulator NPT3/4, psi Gauge 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 GFR600C20MJF2TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 3/4 in NPT port, with the standard 40 um filter element and a manual drain bowl, so condensate is released only when an operator opens the drain - a deliberate choice for lines with scheduled maintenance rounds. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), and the embedded square gauge is supplied with a psi scale. A reverse/check valve is fitted, and the unit comes without a mounting bracket. At size 600 the bowl is aluminium alloy, and the working temperature range 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, and options including automatic or differential-pressure drains, a 5 um (W) filter element, MPa/psi/bar gauge scales, G or NPT threads and a low-pressure regulator type. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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.

Filtered, regulated air supplied to spray-booth drops, with the manual drain opened during scheduled shift checks to clear accumulated condensate before it reaches the finish.
Pressure-regulated air feeding the clamp and flap cylinders on a packaging conveyor, with the check valve holding the set pressure against momentary upstream dips.
Conditioned air for the bottle-clamp and capper actuators on a filling line, where the 40 um element keeps debris out of the valve seats and the psi gauge gives operators a local setpoint readout.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up to it when your line's flow demand outgrows a 400-size unit - and match the thread to your piping: PT is the catalogue standard, with G (BSPP) and NPT (this model) as order options. For the drain, choose manual (as here) when maintenance staff bleed the bowl on a schedule, automatic when the unit is hard to reach, or the default differential-pressure type. The standard 40 um element suits general plant air; specify the 5 um (W) grade where downstream equipment needs finer filtration. The square gauge is fitted here with a psi scale; MPa or bar scales and an external round gauge are alternatives. A bracket can be ordered on variants that include one - this J-coded unit ships without it. Because flow for this series is published as curves rather than a single rated figure, send us your application details and we will confirm 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 number, so we do not quote a l/min or SCFM figure. Send us your application details and we will confirm the relevant datasheet flow curve and sizing on request before you order.
The M in the code specifies a manual drain: condensate is released only when an operator opens the drain, which suits lines with regular maintenance rounds. If you prefer hands-off operation, the same GFR600 body is available with an automatic drain (code A) or the default differential-pressure drain - just ask for the alternative model code.
