The AirTAC GFR60020C3TK 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 PT3/4" 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 GFR60020C3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 3/4 in NPT port, 40 um standard filtration, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough. The fitted external round gauge reads in bar, the built-in reverse/check valve holds downstream settings when upstream pressure is lost, and the mounting bracket is included. The size-600 aluminium alloy bowl suits demanding plant environments where a polycarbonate bowl would not be the first choice.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, 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 scale choices, and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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.

Dropped in on a 3/4 in branch line feeding a production hall, the GFR60020C3TK cleans water and scale out of the plant air and holds a set working pressure for the tools and actuators on that branch, with the differential-pressure drain handling condensate through normal operation.
On a packaging or conveyor line with cylinders and air-driven diverters along its length, this unit filters the supply and regulates it to the pressure the line was designed around, while the reverse/check valve keeps the downstream circuit holding its setting if upstream supply dips.
Feeding a manifold of directional valves and actuators on a machine or process skid, the 40 um grade keeps debris out of valve seats, the regulator holds a stable operating pressure for repeatable actuation, and the bar-scale round gauge gives operators a direct local reading.
Sizing a GFR starts with the port step: this unit is the 3/4 in NPT size-600 position, the largest in the family, intended where the air demand points to the top of the range. Match the port to your piping rather than upsizing blindly, and confirm the flow requirement against the published curves before ordering. The drain here is differential-pressure, which suits a steady-duty installation; an automatic drain (code A) or a manual drain (code M) are the alternatives if your duty cycle or maintenance routine calls for them. Filtration is the 40 um standard grade; specify 5 um (code W) only where downstream equipment genuinely needs finer filtration. The gauge on this unit is the external round type with a bar scale; MPa and psi scales are the other catalogue choices. Thread is NPT here, with PT standard and G available as options. A bracket is included, and the K code means a reverse/check valve is fitted.
Because flow for the GFR series is published as curves and not as a single rated number, we do not quote one here. Send us your application details and we will confirm the sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 number here. Tell us your line pressure, downstream pressure target and air demand, and we will confirm the flow figures from the datasheet for your application on request.
K means a reverse/check valve is fitted, so the downstream side holds its pressure setting if the upstream supply is lost. The drain on this unit is differential-pressure type: condensate collected in the bowl is discharged automatically when the pressure differential across the bowl reaches the discharge point, with no manual draining needed in normal service. Automatic (A) and manual (M) drains are the other catalogue options.
