The AirTAC GFR600C20MC2TK 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 GFR600C20MC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body, sized 600 with a 3/4 in NPT port. This configuration carries a 40 um standard filter element, a manual drain on the bowl, a fitted reverse/check valve, and an external round pressure gauge with a psi scale. The 600-size bowl is aluminium alloy. The standard regulator adjusts outlet pressure across 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, square or round gauges in MPa, psi or bar scales, and optional reverse/check valves. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

Feeds filtered, regulated air to a 3/4 in-supplied pneumatic press or clamp circuit, with the check valve holding set pressure if the upstream supply dips mid-stroke.
Conditions plant air ahead of quarter-turn actuator control on a process line, giving the operator a local psi gauge and a manual drain for scheduled bowl checks.
Serves high-volume service-bay air drops in a commercial vehicle workshop, filtering line moisture and particulate and setting a stable regulated pressure for impact tools and tyre equipment.
Start with the port step: this unit is size 600 with a 3/4 in NPT thread, the largest GFR frame, so choose it when your line port and expected air demand sit at the top of the range - and match the thread to your piping (PT is the standard thread, with G/BSPP and NPT as order options). Next pick the drain: manual (this unit) means an operator opens the drain periodically; automatic or differential-pressure drains suit unattended installations. Choose the 40 um standard element for general plant air, or the 5 um (W) grade for finer protection. Set the gauge scale - this one reads psi - and add the K reverse/check valve if you need to hold downstream pressure. A mounting bracket is included.
Because AirTAC publishes flow as curves rather than one rated number, ask us to confirm sizing against your actual air demand 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 GFR600 series as curves, not as a single rated figure, so we do not quote one number. Send us your line pressure, set pressure and air demand and we will confirm the flow figures from the datasheet for your application on request.
M is the manual-drain code: an operator opens the bowl drain to expel collected water, which suits attended installations on a maintenance round; automatic and differential-pressure drains are available on other GFR codes for unattended duty. The trailing K means a reverse/check valve is fitted, holding downstream pressure if supply is lost.
