The AirTAC GFR600C20MJNWT 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 GFR600C20MJNWT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds the downstream pressure at your setpoint in a single body. This configuration is the size 600 unit with a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, no gauge fitted and no mounting bracket included. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) setting range, maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature is -5 to 70 C (non-freezing), and at size 600 the 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 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and bracket options, and an optional reverse/check valve. Air flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

A 3/4 in branch feeding a spray-booth header: the 5 um element takes fine particulate out of the supply and the regulator holds a steady setpoint to the spray guns, with the manual drain emptied at shift checks.
Filtered, regulated air for clamps, tool-change cylinders and air blast on a machining centre, with the 3/4 in NPT port suiting a main drop feeding the cell's pneumatic distribution manifold.
Clean, regulated air to conveyor diverters, stop gates and bottle-grip cylinders on a filling line, with water and compressor wear particles removed before they reach the valves.
Within the GFR range the real decodable choices are: size and port (200/300/400/600, 1/8 to 1 in) matched to the air demand of the line; drain type - manual as on this unit, automatic, or the differential-pressure default; filter grade, 40 um standard or the 5 um W option fitted here where finer particulate removal matters; a gauge and scale if you want pressure indication fitted (this unit ships without one); thread, with PT as the standard and G or NPT to order; and the bracket option. Flow for the series is published as curves, not a single rating, so send us your air demand and operating pressure 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 rather than a single rated figure, so we do not quote a number here. Tell us your air demand and operating pressure and we will confirm the flow from the datasheet on request.
The W code specifies the finer 5 um element instead of the 40 um standard, for work where finer particulate removal matters; the M code specifies a manual drain, so the bowl is emptied by hand rather than automatically. Both are catalogue choices - the 40 um grade and automatic or differential-pressure drains are available in the same series if they suit your application better.
