The AirTAC GFR600C20A LF2GK 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 AirTAC GFR600C20ALF2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit carries a G3/4 (BSPP) port, the largest step in the G-series range, and is the low-pressure type for circuits that run at reduced set pressures. It is fitted with an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the supply is removed. The metal bowl on this 600 size is aluminium alloy, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic, manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Drops a 3/4 in G-threaded plant air main down to a controlled low-pressure supply for a packaging hall, filtering out water and pipe scale while the automatic drain keeps condensate off the floor without daily walks.
Feeds a conveyor-mounted blow-off and air-knife station that runs at reduced pressure, with the 40 um element stopping rust particles from blocking nozzles and the square psi gauge giving operators a visible setpoint.
Regulates the clamping circuit of a pneumatic press fixture at a low set pressure, where the reverse/check valve holds the clamp if the supply drops and the included bracket fixes the unit to the machine frame.
Start with the port and size: 600 is the largest G-series step, with a G3/4 port here, so size up from smaller 200-400 units when the circuit demands higher flow; match the curve to your demand rather than a single rating. This unit is the low-pressure type, intended for circuits regulated well below the standard range - confirm the exact adjustment range with us, as it is not published in the standard table. The automatic drain suits unattended installations; choose manual (M) or differential-pressure (blank) if you prefer operator control or energy-saving blowdown. The 40 um element is standard; specify W for the 5 um grade where finer filtration is needed. The square gauge is fitted here reading psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP); PT is the standard offering and NPT is an order option. Bracket is included. We confirm flow and datasheet figures on request 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 curves, not as a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code selects the automatic drain, which discharges collected condensate on its own so the bowl does not need manual draining. F2 selects the embedded square gauge with a psi scale; MPa or bar scales and an external round gauge are available alternatives. The K in the code also means a reverse/check valve is fitted.
