The AirTAC GFR60020LC2G AirTAC Filter Regulator G3/4 Low-Pressure 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 GFR60020LC2G is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-600 unit is built around a G3/4 (BSPP) port and is the low-pressure type, fitted with a 40 um filter element and a differential-pressure drain that bleeds condensate away as air passes through. The bowl on this size is aluminium alloy, a mounting bracket is included, and the C2 in the code specifies an external round gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with manual or automatic drains, a 5 um element (code W), different gauge scales, PT or NPT threads in place of G, and with or without a bracket. Flow is published as curves rather than a single rating, so we 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

On a machining or assembly fixture, clamps and swing cylinders need clean air and a steady, moderate set pressure held through the cycle. This unit filters water and pipe debris at the fixture drop and lets the setter dial in and read the clamp pressure on the psi gauge.
Carton sealers, case erectors and pick-and-place cylinders on a packaging line share one shop-air drop. A filter regulator at the line's takeoff keeps rust, scale and condensate out of the valves and holds a stable supply pressure for the whole machine.
At a paint or coating booth, the atomizing air must be free of water slugs and pipe scale, and the operator needs to set a repeatable pressure at the booth. This unit cleans the drop and gives the operator a direct-reading psi gauge for the set point.
Start with the port step: size 600 carries a 3/4 in port, and the trailing G orders G (BSPP) threads - PT is the standard thread and NPT is also a catalogue option, so match the thread to your piping. The L in the code selects the low-pressure regulator type; the exact adjustment range for this variant is not published, so ask us to confirm it against your set pressure. Drain choice is real: the default differential-pressure drain used here, an automatic drain (A) or a manual drain (M). The element is 40 um as standard; order code W for 5 um. Gauge options are the embedded square gauge or an external round gauge, in MPa, psi or bar scales - C2 here means a round psi gauge. A bracket is included; J deletes it. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR600 as curves rather than a single rated figure, so there is no one number we can quote. Send us your upstream pressure, set pressure and expected air consumption, and we will read the datasheet curve and confirm the sizing on request before you order.
It specifies the gauge: C is the external round gauge (the embedded square gauge is the standard fitting) and 2 is the psi scale; use 1 for MPa or 3 for bar. The rest of the code decodes as size 600 with a G3/4 port, G thread, low-pressure type, 40 um element and differential-pressure drain.
