The AirTAC GFR600C20MJC3T AirTAC Filter Regulator 3/4in 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 AirTAC GFR600C20MJC3T 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 standard filter element, a manual drain on the aluminium alloy bowl, and an external round gauge reading in bar. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um (W) element option, gauge scale choices, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Point-of-use filtered and regulated supply for pneumatic impact wrenches and nutrunners at assembly stations, with the 3/4 in NPT port feeding a branch header serving multiple tool drops.
Conditioning the air feeding cylinder-driven case erectors, carton sealers and diverters on a packaging conveyor line, where the manual drain is bled during scheduled changeover stops.
Filtered, regulated air for pneumatic valve positioners and pilot solenoids on a process skid, with the bar-scaled round gauge letting technicians verify set pressure at the panel.
Start with the size and port step: size 600 with its 3/4 in NPT port suits lines with higher air demand, while smaller sizes (200/300/400) step down in port and physical scale - match the step to the flow your circuit needs and ask us to confirm against the published curves before ordering. Choose the drain to suit access: manual drain (this model) needs an operator to bleed the bowl, automatic drain suits unattended installations, and differential-pressure drain is the catalogue default. The 40 um element is standard; specify the 5 um (W) grade where finer filtration is required. This unit carries an external round gauge reading in bar; embedded square gauges and MPa/psi scales are the other catalogue options. NPT is ordered as the thread option here, with PT standard and G available. No mounting bracket is fitted on this code (J); brackets are optional on GFR. Because flow is published as curves rather than a single rating, send us your application conditions and we will confirm sizing 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 rated flow, Cv or SCFM figure. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain, which means the aluminium alloy bowl is bled by hand - a good fit where the unit is checked during routine maintenance rounds. The catalogue also offers automatic and differential-pressure drain variants on the GFR family, and the 5 um (W) filter grade is available if finer filtration than the standard 40 um element is needed.
