The AirTAC GFR600C20ALF2W AirTAC Filter Regulator PT3/4, 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 AirTAC GFR600C20ALF2W is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in PT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type fitted with an embedded square gauge scaled 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 is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um standard or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application against the datasheet.

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 a 3/4 in main drop feeding the cylinder and valve groups on a bottling or filling line: the 5 um element strips water and fines ahead of the valves, the low-pressure regulator holds the circuit at the pressure the machine builder specified, and the automatic drain keeps condensate off the shop floor.
Mounted on the bracket at the supply point of a packaging conveyor section, where stopper and pusher cylinders need clean, regulated air. The square psi gauge gives operators a direct read of the set pressure, and the automatic drain suits a header position that is not checked every shift.
Used on the air supply of a test rig or laboratory automation skid where instruments and small actuators call for finer-than-standard air and a lower regulated pressure. The 5 um grade protects the hardware, and the psi-scaled gauge lets technicians set and verify the working point at a glance.
Step up or down through the GFR sizes (200/300/400/600) and their port sizes (1/8 in to 1 in) to match the air demand of the line - the 600 size with its 3/4 in PT port is the larger end of the range. Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm sizing from the datasheet before you order. On this unit the drain is automatic, which suits points where condensate collects but nobody walks past; manual and differential-pressure drains are the other catalogue choices on other variants. Filtration here is the 5 um (W) element - choose it where downstream valves, cylinders or instruments want finer air than the 40 um standard grade delivers. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. PT thread is the standard on this code, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
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 GFR600 flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator variant of the GFR600, intended for circuits regulated below the standard type's range. The exact setting range for this variant is not published in our data sheet, so please confirm it with us on request. The unit's maximum working (inlet) pressure is 1.0 MPa (145 psi), the fitted square gauge reads in psi, and the automatic drain handles condensate without manual intervention.
