The AirTAC GFR60020C2K AirTAC Filter Regulator PT3/4 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 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 GFR60020C2K is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is threaded PT3/4, uses the standard 40 um filter element, and drains condensate by differential pressure, so the bowl empties automatically as flow passes through - no manual draining in normal service. Because this is the 600 size, the bowl is aluminium alloy, and the unit ships with a mounting bracket. The C2 code adds an external round pressure gauge reading in psi, and the K code means a reverse (check) valve is fitted, holding downstream pressure if the upstream supply is lost.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 5 um element option, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us and we will 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.

Feeding carton sealers, case erectors and wrapping machines on a packaging line, where clean, dry air at a steady regulated pressure keeps cylinders and vacuum generators cycling consistently through a 3/4 inch main.
Supplying the air cylinders that raise gates, stops and diverters along a conveyor system, with the regulator holding a fixed set pressure so gate timing and clamping force stay repeatable shift after shift.
Mounted at the air inlet of a CNC machine or automated workholding panel, filtering incoming shop air to 40 um and regulating it before it reaches clamps, tool changers and air-assisted spindles.
Start with size and port: GFR600 is the largest step in the family and carries a 3/4 inch PT thread, so match it to your main line and the flow your actuators need - we can confirm the flow curve against your demand before you order. Next, choose the drain: this unit uses the differential-pressure drain (the default), while automatic and manual drains are orderable alternatives. The 40 um element is the standard grade; specify the W code if your application needs the finer 5 um filtration. On the gauge side, the embedded square gauge is standard and this code selects the optional external round gauge with a psi scale (MPa and bar scales are also available). Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket is included. Because flow is published as curves, not a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet so you can size the unit correctly before ordering.
C2 means this unit carries the optional external round pressure gauge with a psi scale (the embedded square gauge is standard, and MPa or bar scales are also available). K means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply drops. The blank drain code is the differential-pressure type, and the blank filter code is the standard 40 um element.
