The AirTAC GFR60020MLJC3T 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 PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLJC3T is a size-600 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is fitted with a 3/4 in NPT port, a 40 um filter element, a manual drain for the aluminium alloy bowl, and a round external gauge reading in bar. It is the low-pressure type, intended for circuits where the set pressure sits below the standard regulator range, and 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 family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread form and bracket. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds filtered, pressure-set air to the grip and lift cylinders on a bottling or canning line, with the round bar gauge letting operators verify set pressure at a glance and the manual drain bled during shift checks.
Sits upstream of the clamping cylinders on a CNC fixture circuit, taking water and swarf-carrying condensate out of the shop air and holding a steady low set pressure so workholding stays consistent across a batch.
Provides regulated, filtered air to the low-pressure section of a packaging machine, where the low-pressure type regulator and 40 um element protect sensitive actuators and the manual drain is emptied during scheduled maintenance.
Start with the port step: this unit is the size-600 body with a 3/4 in NPT port, the largest in the GFR range, so check that your line's flow demand sits comfortably within the size-600 curve before ordering. Choose the drain to match duty: this unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine; pick automatic or differential-pressure drain codes where the unit is inaccessible. Filter grade is 40 um as coded here; specify W for the 5 um element if downstream valves or instruments need finer air. The C3 code gives a round gauge with a bar scale; square embedded gauges and MPa or psi scales are alternatives. Thread is NPT as ordered, with PT (standard) and G also available as catalogue options. This is the low-pressure (L) type, so confirm your set pressure suits a low-pressure regulator. No bracket is included with the J code; add a bracket code if you want panel or wall fixing. Ask us to confirm sizing against the application before ordering, since flow is published as curves, not a single rating.
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 rather than a single rated figure, so there is no one rated flow number we can quote. Send us your line pressure, set pressure and air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code sets a manual drain: the aluminium alloy bowl is emptied by hand, which suits installations an operator visits routinely; automatic and differential-pressure drain versions are available as other codes. C3 specifies the round external gauge with a bar scale, while an embedded square gauge with MPa or psi scales can be ordered instead.
