The AirTAC GFR600C20MJC1WTK 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 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 GFR600C20MJC1WTK is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, a round external pressure gauge scaled in MPa, and a built-in reverse/check valve. The bowl on size 600 units is aluminium alloy, and no mounting bracket is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -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 a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge style and scale, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to 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.

Feeding a plant-air branch that runs a pneumatic press: the 5 um element strips water and fine particulate before the air reaches the regulator, which holds a stable set pressure to the press cylinders, while the check valve protects the setting from upstream dips.
Supplying filtered, regulated air to the stopper and pusher cylinders on a packaging conveyor line: the manual-drain bowl is bled during scheduled line cleaning, and the 3/4 in port suits a main drop feeding multiple actuators.
Conditioning the supply to the clamping fixtures on a CNC machine tool: clean, moisture-reduced air at a fixed regulated pressure keeps clamp force consistent, and the MPa gauge gives the operator a direct reading at the machine.
Work from the size and port first: GFR600 is the largest step in the range and carries a 3/4 in port, so match it against the air demand of the circuit - flow is published as curves, not a single rated figure, so have us confirm sizing against your application before ordering. This unit pairs the 5 um element (code W) with a manual drain, which suits installations where an operator can bleed the bowl on a routine basis; automatic or differential-pressure drains are the catalogue alternatives if unattended drainage is preferred. The round gauge fitted here reads in MPa, with psi and bar scales available as options, and the fitted check valve holds downstream settings if upstream supply is interrupted. Thread is NPT on this unit, with PT (standard) and G as order options, and no mounting bracket is included.
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 figure, so we do not quote a flow number here. Tell us your application and we will confirm the relevant datasheet figures on request before you order.
The M in the code specifies a manual drain: the bowl must be bled by hand at intervals. If the installation runs unattended, the catalogue alternatives for GFR units are an automatic drain (code A) or a differential-pressure drain (blank), and the 5 um element (W) can likewise be ordered as the standard 40 um grade.
