The AirTAC GFR600C20AC2K AirTAC Filter Regulator 3/4 in PT 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 GFR600C20AC2K is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration carries PT3/4 ports, a 40 um filter element, an automatic drain that expels collected condensate without manual attention, and an aluminium alloy bowl suited to the larger 600 frame. The standard regulator section adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the fitted reverse/check valve holds downstream settings if upstream pressure is lost. A round external gauge on a psi scale is included, and the unit ships with its mounting bracket. Operating temperature is -5 to 70 C (non-freezing), medium is compressed air only.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the series you can order a 5 um element (code W), manual or differential-pressure drains, square embedded or round external gauges on MPa, psi or bar scales, and G (BSPP) or NPT threads instead of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers for your application before ordering.

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.

Installed at the drop to a machining centre, the GFR600C20AC2K removes water and swarf-laden particulate from the shop air line and holds a steady regulated pressure to the machine's pneumatic circuits, with the automatic drain handling condensate in an unsupervised cell.
Mounted ahead of the valve manifold feeding conveyor stoppers and carton-forming cylinders on a packaging line, this unit delivers filtered, regulated air at a set pressure so actuators cycle consistently through the shift.
Fitted on the compressed air ring main serving a laboratory or test facility, the 40 um element and regulation protect sensitive pneumatic instruments and bench equipment, while the psi-scaled gauge gives technicians a direct reading of line pressure.
Start with the size and port step: 600 is the largest GFR frame, and the 3/4 in PT port here should be matched against the pipe size and air demand of the circuit - step up or down through 200/300/400/600 if your line uses a different port. Choose the drain to suit access: automatic (this model) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the family default. The 40 um element is standard; specify the W option for 5 um filtration where downstream equipment needs finer air. Gauge scale (MPa, psi or bar - psi here), embedded square versus external round gauge, PT versus G/NPT thread, and the bracket are all decodable order choices. Flow for this series is published as curves, not a single rating, 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your application - working pressure, downstream demand and pipe run - and we will confirm the relevant datasheet flow figures for this model on request before you order.
The automatic drain (code A) expels condensate collected in the bowl without anyone having to open it, which suits units mounted in out-of-the-way or infrequently visited positions. The GFR family is also available with manual drain (code M) or the differential-pressure drain default, so you can match the drain to how the installation is maintained.
