The AirTAC GFR600C20AC2T AirTAC Filter Regulator NPT 3/4 in 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 AirTAC GFR600C20AC2T is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has NPT 3/4 in ports, an automatic drain that expels collected condensate without manual attention, standard 40 um filtration, a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round pressure gauge with a psi scale. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At the 600 size the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published 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.

Point-of-use clean, regulated air for clamps, tool-changers and actuated gates on a machining centre, with the automatic drain handling condensate between shifts.
Filtered, regulated air for carton-forming and case-sealing cylinders on a packaging conveyor, where stable downstream pressure keeps cycle motion consistent.
A 3/4 in main-air drop feeding a row of assembly benches, delivering dried, particulate-free air at the pressure each station's tools and fixtures need.
Start with the port step: this unit is the 600 size with 3/4 in ports, the largest in the GFR range - match it to your line size and required flow, stepping up a size if the curve does not cover your demand. Drain type is a real choice: this unit has an automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other codes. Filtration is 40 um standard, with 5 um (code W) where finer protection is needed. The gauge here is the external round type with a psi scale; an embedded square gauge with MPa, psi or bar scales is the alternative. Thread is NPT on this code, with PT and G available to order, and a mounting bracket is included.
One honest note before ordering: flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you commit.
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 as curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet for your application on request.
The A in the code means condensate is discharged automatically from the bowl, so the unit keeps protecting the downstream regulator and equipment without anyone opening a drain valve - useful for elevated, enclosed or infrequently visited installations. Manual and differential-pressure drain versions are available on other GFR codes if you prefer control over drain timing.
