The AirTAC GFR600C20ALF2WG AirTAC Filter Regulator G3/4, 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 GFR600C20ALF2WG is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a G3/4 (BSPP) port, a fine 5 um filter element (code W, versus the 40 um standard), and an automatic drain that bleeds collected condensate from the bowl without manual attention. The regulator is the low-pressure type for circuits that run below standard line pressure, and the fitted square gauge reads 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 port sizes from 1/8 to 1 inch, and can be ordered with manual or differential-pressure drains, a 40 um or 5 um element, different gauge scales, PT, G or NPT threads, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the 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 drop of a 3/4 inch main, it filters the shop air to 5 um and holds a reduced, stable supply to low-pressure actuators on carton-forming and sealing stations, while the automatic drain keeps condensate out of the valves.
Mounted on the bracket ahead of a conveyor section, it cleans and regulates the air driving gate and stopper cylinders, with the psi square gauge giving operators a local reading at the line and the metal bowl standing up to plant duty.
Feeding pilot air to large diaphragm valves, the 5 um element protects the valve pilots from particulate and water, and the low-pressure regulator type matches the modest actuation pressures such skids run at.
Start with the port step: this unit is size 600 with a 3/4 inch G-thread port, the largest in the GFR range - step down to sizes 200/300/400 for smaller lines, but match the port to your piping rather than oversizing on guesswork, since flow is published as curves and we will confirm sizing against your demand on request. Choose the drain: automatic (this unit, code A) suits unattended duty; manual (M) suits intermittent inspection; differential-pressure (blank) is the default. Choose the element: 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um grade. The gauge scale is selectable (MPa, psi or bar); this one is square, psi. Thread is PT as standard with G and NPT as order options - this unit is G. A bracket is included, and the low-pressure regulator type (L) is selected for circuits below standard pressure; its exact adjustment range is not published, so confirm it with us.
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, not as 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 G3/4, 5 um, low-pressure configuration before you order.
This unit (drain code A) discharges collected condensate from the bowl automatically, so it suits installations that run unattended. The alternatives are a manual drain (code M), which you open during inspection, and the differential-pressure drain (blank), which is the catalogue default. All three are order choices on the GFR family.
