The AirTAC GFR60020ALC3WT AirTAC Filter Regulator, NPT3/4, 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 GFR60020ALC3WT is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in one body. This configuration is a 3/4 in NPT-threaded unit with a 5 um filter element (40 um is the family standard), an automatic drain that expels collected condensate on its own, a low-pressure regulator type, and a round pressure gauge with a bar scale. The 600-size 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 in up to 1 in, and options for G (BSPP) or NPT threads, manual or differential-pressure drains, a 40 um or 5 um element, gauge style and scale, 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 sizing figures from the datasheet 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. 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 CNC fixture line fed at reduced supply pressure, this filter regulator conditions the air and holds the clamp circuit's setpoint. The 5 um element keeps directional valve spools and clamp-cylinder orifices clear of particulate and water, and the low-pressure regulator type suits a header that does not run at full line pressure.
Ahead of the directional valves and pusher cylinders on a cartoning or case-packing conveyor, this unit filters and regulates the 3/4 in supply drop. The automatic drain expels collected condensate without operator rounds, and the round bar gauge gives a local setpoint check at the machine.
On a 3/4 in ring-main drop feeding impact wrenches, vehicle lifts and blow guns, this filter regulator cleans the air and sets a stable working pressure. The aluminium alloy bowl is standard at size 600, the mounting bracket fixes the unit to the wall frame, and the bar-scale gauge lets technicians verify the setting.
Size and port step up together: 200, 300, 400 and 600 map to ports from 1/8 in up to 1 in, and this unit sits at the top of the range on 3/4 in NPT threads (PT is the standard thread; G and NPT are order options). Where a bowl is fitted you choose the drain - automatic (this unit), manual, or differential-pressure - and the filter grade: 40 um standard or 5 um (W) for finer protection. Units with a regulator take a gauge, embedded square as standard with an external round optional, in MPa, psi or bar scales, and GF/GR/GL/GFR bodies can be ordered with or without a bracket. Because AirTAC publishes flow only as curves, not a single rated figure, send us your application details and we will confirm sizing from the datasheet before you order.
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 GFR600 as curves, not as a single rated figure, so we do not quote a number here. Send us your application details - port size, downstream demand and line pressure - and we will confirm the flow curve and sizing from the datasheet on request.
The A in the code means an automatic drain, which expels collected condensate from the bowl without manual intervention. The GFR family also offers a manual drain (M) and a differential-pressure drain (blank, the family default). This unit's bowl is aluminium alloy, as is standard at size 600, and its maximum inlet pressure is 1.0 MPa (145 psi) with a -5 to 70 C working range.
