The AirTAC GFR600C20AJC1T AirTAC Filter Regulator NPT3/4, Auto Drain 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 GFR600C20AJC1T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that discharges collected condensate without manual attention, and a round pressure gauge with an MPa scale so the set pressure is visible at the unit. The maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjustment range is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C (non-freezing). The size 600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with options including manual or differential-pressure drains, a 5 um (W) filter element, square or round gauges with MPa, psi or bar scales, a low-pressure regulator type, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow 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. 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 drop feeding a packaging machine's valve island, it strips water and pipe scale from the plant air and holds a steady regulated pressure so sealing and carton-forming cylinders cycle consistently. The automatic drain keeps condensate off the floor in an area nobody inspects daily.
Mounted ahead of the air cylinders and air bearings on a bottling-plant conveyor section, it removes moisture that would otherwise carry into the drive circuit and regulates supply pressure for smooth, repeatable product handling. The MPa gauge lets a technician verify the set point at a glance.
Used as the single filter-regulator at the inlet of an OEM machine's pneumatic panel, it conditions the shop air and sets the working pressure for all downstream circuits from one point. The NPT3/4 port matches the panel's main air entry, and the aluminium bowl suits the higher-flow 600 frame.
Size and port are the first choice: the 600 frame with its 3/4 in NPT port suits lines that need the larger end of the GFR flow range, while 200/300/400 frames cover smaller ports. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your air demand before ordering. Drain type is a real decision here: this unit has an automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other codes. The 40 um element is standard - choose the 5 um (W) element where downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) should be matched to the rest of the installation. A mounting bracket is not fitted on this code; bracketed versions exist.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your operating pressure and air demand and we will confirm the flow and full datasheet figures for this exact model on request before you order.
The A in the code selects the automatic drain, which discharges collected condensate by itself - useful where the unit is mounted out of easy reach. Other GFR codes offer a manual drain (M) or the differential-pressure drain (blank), and the regulator adjustment range differs by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
