The AirTAC GFR600C20ALF1WT AirTAC Filter Regulator NPT3/4 5 um 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 GFR600C20ALF1WT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 configuration carries a 3/4 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that discharges collected condensate without manual attention, and a low-pressure regulator fitted with an embedded square gauge scaled in MPa. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm flow 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 packaging hall, the unit strips water and fine particles from the supply and holds a steady reduced pressure to the hall's actuators, while the automatic drain keeps condensate off the floor without daily attention.
Mounted ahead of the valve manifold on a conveyor line, the filter regulator cleans the shop air feeding blow-off nozzles and product-stop cylinders, and the low-pressure regulator holds the gentle, stable setting those devices need.
On a laboratory test rig or autoclave air supply, the 5 um element protects sensitive instruments from fine particulate and water carryover, and the MPa gauge gives a direct local reading of the regulated pressure.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range; work up through sizes 200, 300, 400 and 600 as your required flow grows, since port size and flow capacity rise together. This unit is already specified with the finer 5 um element (choose 40 um where only coarse protection is needed), an automatic drain (choose manual for supervised installations or differential-pressure drain as the default), and a square MPa gauge (psi or bar scales and an external round gauge are alternatives). The low-pressure regulator type suits circuits that hold reduced pressure below the standard regulator's range; PT is the standard thread, with G and NPT as catalogue options to order, and a mounting bracket is included. Because flow is published as curves rather than a single rating, 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and the flow your application needs, and we will confirm from the datasheet curves that this 3/4 in, size 600 unit is correctly sized before you order.
The code decodes them: A is the automatic drain, which discharges collected condensate by itself instead of waiting for a manual or differential-pressure drain cycle, and W is the 5 um filter element, one grade finer than the 40 um standard. Both are catalogue options on the GFR family, so you can order the same unit with a different drain or grade if your installation prefers.
