The AirTAC GFR600C20AC1TK AirTAC Filter Regulator NPT3/4 Auto Drain 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 GFR600C20AC1TK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 unit is fitted with a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an aluminium alloy bowl, which is the bowl material used across the 600 size. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). A round pressure gauge scaled in MPa is fitted, a reverse/check valve is included, and a mounting bracket comes with the unit. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), manual or differential-pressure drain alternatives, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow figures for this family are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Placed ahead of a CNC machining center's pneumatic clamps and tool-change cylinders, this unit strips water and swarf-laden condensate from the shop air and holds a steady regulated pressure so clamping force does not drift during a cycle.
On a bottling or filling line, this 3/4 in filter regulator feeds the conveyor stop gates, lifters and capper cylinders, with the automatic drain clearing condensate from the bowl through continuous shifts without an operator stopping at each unit.
Installed upstream of a solenoid valve manifold on an assembly line, it delivers clean, pressure-stable air to the valves, and the fitted reverse/check valve helps hold the regulated pressure if the main supply dips.
Start with the size and port: 600 is the largest GFR frame, and this unit carries a 3/4 in NPT port, so match it to the air consumption of the downstream circuit - step up a size if the line feeds many actuators at once. Choose the drain to suit access: automatic (this unit) drains itself, manual needs an operator, and the differential-pressure default drains on a pressure drop. The 40 um element is standard; specify the W code for 5 um where finer filtration is needed. Gauges are available embedded square or external round, in MPa, psi or bar scales - this unit has a round MPa gauge. Thread is PT as the catalogue standard, with G and NPT as orderable options (this unit is NPT); a bracket is included.
Flow for the GFR series is published as curves, not a single rated figure, so send us your application details 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 GFR-series flow as performance curves rather than a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
This code carries an automatic drain, which ejects collected condensate from the bowl on its own - useful where the unit is mounted in a hard-to-reach spot. The family also offers manual drain and a differential-pressure drain as the default; all three keep the same 0.15-0.9 MPa (20-130 psi) regulation range on this unit.
