The AirTAC GFR60020ALF2W AirTAC Filter Regulator PT3/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a automatic 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 GFR60020ALF2W is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit is ported PT3/4 (PT thread standard; G and NPT are order options), carries a 5 um filter element (code W, against the 40 um standard), drains condensate automatically, and is the low-pressure regulator type. The fitted embedded square gauge reads in psi; an external round gauge in MPa, psi or bar scale is available as an option. The bowl is aluminium alloy, standard at size 600, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge style and scale, a reverse/check valve, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 finishing line, the 5 um element strips water and fine particulate before air reaches the spray guns, while the low-pressure regulator holds a gentle, steady supply pressure at the booth manifold.
Feeding the cylinders and air bells on a cartoning conveyor, this unit cleans the shop air and keeps the supply pressure steady so stoppers, pushers and flap-folders repeat their stroke consistently.
On a bench rig running pneumatic trials, the 5 um grade protects sensitive instrumentation from condensate and grit, and the low-pressure regulation lets technicians hold a mild, controlled test pressure.
Size and port step up together: 200, 300, 400 and 600, with ports from 1/8 inch to 1 inch - pick the step that matches the flow your line needs, then set the thread: PT is standard, while G (BSPP) and NPT are order options. This unit is the low-pressure type (code L); its exact regulation range is not published in the material we hold, so confirm it with us against your set pressure. Drain choice matters: automatic (this unit, code A) discharges condensate without attention, manual needs a periodic twist, and differential-pressure drains only as the element loads up. Filtration here is 5 um; the 40 um standard element suits general lines where finer filtration is not required. The embedded square gauge fitted reads psi, or specify an external round gauge in MPa, psi or bar. Flow is published as curves, not 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 this series as curves, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure regulator type, as opposed to the standard type. Its exact regulation range is not published in the material we hold, so share your set pressure with us and we will confirm suitability from the datasheet.
