The AirTAC AirTAC GFR600C20MJC2GK Filter Regulator G3/4, Manual Drain 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 GFR600C20MJC2GK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 port (G thread; PT is the standard thread form, with G and NPT available as order options), a 40 um standard filter element, and a manual drain, so condensate is released by opening the drain valve by hand. The built-in check valve (code K) holds downstream pressure when the upstream supply is removed. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and this unit is fitted with an external round gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The size-600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include automatic, manual or differential-pressure drains, a 5 um filter element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so contact us and we will confirm the datasheet and sizing 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.

At a 3/4 inch main drop feeding a CNC machining cell, this unit filters water and swarf-carrying particulate from the plant air line and holds a set working pressure for the cell's pneumatic valves and actuators, with the check valve holding the setting during supply interruptions.
On a bottling or packaging conveyor line, the unit conditions the air feeding cylinder-driven pushers and clamps: the 40 um element stops particulate reaching the cylinders while the regulator keeps actuator pressure consistent across the shift, read directly on the psi gauge.
On a service truck or maintenance vehicle with an on-board compressor, this filter regulator conditions the 3/4 inch supply to impact wrenches and inflation equipment, with manual drain bleeding suited to end-of-day shutdown and the psi gauge giving the operator a direct pressure readout.
Size 600 is the largest step in the GFR range, so start there when your line volume points to a 3/4 inch port; smaller 200/300/400 sizes cover 1/8 to 1/2 inch ports. For the drain, choose manual (as here) when the unit is accessible and someone can bleed condensate routinely; choose automatic where unattended continuous drainage matters, or differential-pressure drain as the default. The 40 um element suits general plant air; specify the 5 um (W) option only where downstream equipment needs finer filtration. Gauge scales are available in MPa, psi or bar - this unit ships with a round psi gauge, and an embedded square gauge is the standard alternative. Thread is G here; PT is the standard form and NPT is an order option. A mounting bracket is not included with this code (J), so plan the mounting accordingly.
One honest note before ordering: flow for the GFR series is published as curves, not as a single rated number, so we cannot quote a rated flow here. Ask us to confirm sizing against your application and we will supply the datasheet figures on request.
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 rated flow, Cv or SCFM number for this unit. Contact us with your application details and we will confirm the datasheet flow curves and sizing on request.
The M in the code selects the manual drain: condensate collected in the aluminium alloy bowl is released by opening the drain valve by hand, rather than automatically. It suits installations where the unit is accessible and can be bled as part of a routine. If the unit will run unattended, ask about the automatic or differential-pressure drain options when ordering.
