The AirTAC GFR600C20ALC1T AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20ALC1T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with 3/4 in NPT ports, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator type. It is supplied with a mounting bracket and fitted with an external round pressure gauge scaled in MPa. The metal bowl at size 600 is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, standard or low-pressure regulator types, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

Installed at the 3/4 in main air drop feeding a CNC machining cell, the unit strips water and chips of particulate from the shop supply and holds a steady low-pressure setting for the cell's actuators and air tools.
Mounted on the supply to a packaging conveyor's pneumatic diverters and stop gates, the filter regulator keeps condensate out of the valves while the low-pressure regulator type holds the gentler setting those cylinders need.
On a skid of quarter-turn pneumatic actuators, the unit conditions the incoming compressed air and regulates it to the actuator supply, with the automatic drain handling condensate so the skid runs without daily bowl draining.
Choose the size 600 / 3/4 in port step when your line runs at the higher end of the GFR flow range; smaller sizes (200/300/400) use smaller ports and suit lighter duty. This unit has the automatic drain, which suits unattended installations; a manual drain (code M) costs attention at each drain interval, and the differential-pressure drain (blank) is the catalogue default. The 40 um element fitted here is the standard grade; specify W for the 5 um grade where downstream equipment needs finer filtration. The low-pressure regulator type (L) is intended for lower set-point work - confirm the exact range with us before ordering. Gauge scales are MPa (1), psi (2) or bar (3), and the round gauge is the external option while an embedded square gauge is standard. Thread is NPT here; PT is the standard thread and G is also available as an order option. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for this exact configuration on request before you order.
The A in the code means the bowl drains collected condensate automatically, so no one has to open the drain by hand - useful on unattended lines. The L code marks the low-pressure regulator type, intended for lower set-point work; its exact adjustment range is not published in the material we hold, so confirm it with us on request.
