The AirTAC GFR600C20ALC2G 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 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 GFR600C20ALC2G is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit carries a G3/4 port with G thread, an automatic drain that purges collected condensate from the bowl without manual attention, the standard 40 um filter element, and the low-pressure regulator type for applications that run below standard regulating ranges. It is supplied with a round external gauge reading in psi, and the aluminium alloy bowl suits the larger 600 frame. A mounting bracket is included.
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, a choice of automatic, manual or differential-pressure drains, an optional 5 um element (code W), square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this model is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Clean, regulated air supply for the air-over-oil or cylinder circuit of a stamping press, where the low-pressure regulator type holds the working pressure the tooling was set up for and the automatic drain keeps condensate out of the valve stack.
Point-of-use treatment for the air cylinders and grippers on a carton-forming and sealing conveyor, with the 40 um element stopping pipe scale reaching the directional valves and the psi gauge giving operators a visible setpoint.
Filtration and regulation ahead of the filler and capper actuator bank in a bottling plant, where the automatic drain handles the condensate load of a wet compressor room and the G3/4 port matches the main drop leg.
Start with the port step: size 600 with a G3/4 connection suits lines plumbed at 3/4 inch, and the larger frame moves more air than the 200/300/400 sizes - match the size to the flow your circuit needs. This unit has the automatic drain, so condensate is ejected without operator input; manual and differential-pressure drains are available on other variants if you prefer a controlled or load-proportional purge. The standard 40 um element is fitted here; choose the W code for 5 um filtration where downstream valves or instruments demand finer air. The round gauge on this unit reads in psi, with square embedded gauges and MPa or bar scales available as alternatives. Thread is G on this model, with PT and NPT offered as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes filter-regulator flow as curves, not a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm the datasheet figures and correct size 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 rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet curves and check the sizing against your required flow before you order.
The L code marks the low-pressure regulator type, intended for circuits that run below standard regulating ranges; the exact regulation range for this variant is not published in the material we hold, so ask us to confirm it on the datasheet. The A code is the automatic drain: the bowl purges collected condensate on its own, with no manual draining, which suits unattended or high-humidity installations. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
