The AirTAC GFR600C20ALC2WT AirTAC 5 um Filter Regulator 3/4 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 GFR600C20ALC2WT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit is built with a 3/4 in NPT port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without attention, the low-pressure regulator type, and a round pressure gauge reading in psi. At size 600 the bowl is aluminium alloy, and a 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 in, and can be ordered with manual or differential-pressure drains, the 40 um standard element, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

On a 3/4 in machine-shop drop, this filter regulator feeds clean, pressure-stabilised air to tool-changer and clamping cylinders, with the 5 um element guarding precision valves from water and swarf-carrying condensate.
Mounted at the head of a bottling conveyor run, the unit filters and regulates the air driving stopper and gate cylinders, while the automatic drain keeps condensate out of the line during long, unattended shifts.
Upstream of carton-closing cylinders on a case-sealing station, this 3/4 in unit removes water and 5 um particulate and holds a steady low-pressure setting, with the round psi gauge giving operators a local readout.
Choose the size by the port and flow step: 200, 300, 400 and 600 map to larger ports (here 3/4 in) and higher air delivery, so step up if your line draws more air than a smaller unit can pass - we will check the flow curve against your demand before you order. Drain type is a real decision: automatic (this unit) clears condensate by itself, manual needs a routine drain, and differential-pressure drains only as the element loads up. Element grade is 40 um standard or 5 um (W) as fitted here for finer protection of downstream equipment. Gauges come as an embedded square gauge or an external round gauge (this unit) with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT as order options - this unit is NPT. Brackets are included unless J is specified. The regulator in this code is the low-pressure type; ask us to confirm its adjustment range from the datasheet, since flow and set ranges are published as curves, not single figures.
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 rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for this exact 3/4 in, 5 um, automatic-drain configuration before you order.
The A in the code fits the automatic drain, which ejects collected condensate by itself instead of relying on a manual drain or a differential-pressure trigger. It suits unattended compressor rooms and lines where a skipped manual drain would let water carry downstream. Manual and differential-pressure drains remain order options in the same size.
