The AirTAC GFR600C20MC1TK 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 GFR600C20MC1TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-600 unit is fitted with a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the aluminium alloy bowl, a round pressure gauge scaled in MPa, a built-in reverse (check) valve, and a mounting bracket. With manual drainage, the regulation range is 0.05-0.9 MPa (7-130 psi) and the maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drainage, a 5 um (W) filter element, embedded square or external round gauges with MPa, psi or bar scales, G, NPT or PT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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 conditioning for the pneumatic clamps, tool-change actuators and chip-clearing blasts on a machining centre, with the regulator set to the pressure the machine builder specifies.
Filtered and regulated air for the pushers, diverters and seal cylinders on a carton packaging conveyor, where the check valve holds the set pressure if the upstream supply dips.
Conditioning the air feeding filler-head lift cylinders and capping heads on a bottling line, with the manual drain emptied during scheduled changeover and cleaning stops.
Size 600 with a 3/4 in port is the large-flow step of the GFR range, so start by matching the port and size step to the air demand of the circuit; we can confirm the flow curve against your requirement before you order. This unit has a manual drain, so an operator drains the bowl on a routine basis - choose automatic drainage if the installation is unattended. The 40 um element is the standard grade; specify the 5 um (W) option where finer filtration is needed. The fitted round gauge reads in MPa, with psi and bar scales available as options. The thread here is NPT; PT is the standard thread and G (BSPP) is also a catalogue option. A bracket is included, and the reverse (check) valve is fitted.
Flow for this family is published as curves, not as a single rated figure, so please ask us to confirm sizing against your application before ordering.
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 l/min or SCFM number here. Tell us your application and we will confirm the flow data from the datasheet so you can check it against your demand before ordering.
T is the thread option: this unit has a 3/4 in NPT port (PT is the standard thread, and G/BSPP is also available to order). K means a reverse (check) valve is fitted, which holds the downstream set pressure if the upstream supply is interrupted. The code also shows M for manual drain, C1 for the round MPa gauge, and no J, so the mounting bracket is included.
