The AirTAC GFR60020ALC1WTK 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 AirTAC GFR60020ALC1WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 5 um filter element (code W), an automatic drain that discharges collected condensate without manual attention, the low-pressure regulator type, an external round pressure gauge scaled in MPa, and a reverse/check valve. The 3/4 in ports are NPT thread. At size 600 the bowl is aluminium alloy, and a mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| 1 | Gauge scale: MPa. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeds filtered, regulated air to the tool-change cylinders and pneumatic clamps on a CNC machining centre, with the 5 um element protecting spool valves from fine particulate and the automatic drain clearing condensate between shifts.
Serves as the conditioning point ahead of the pick-and-place and carton-sealing actuators on a packaging line, holding a steady low-pressure setting for gentle gripper action while the round MPa gauge gives operators a clear setpoint reference.
Conditions the air feeding valve actuators at a bottling plant fill station, where the reverse/check valve holds the downstream setting if supply dips and the automatic drain copes with the moisture load of a humid washdown environment.
Size and port set the capacity envelope: GFR600 steps up to 3/4 in ports for lines that outgrow the 200/300/400 frames, but the right check is the flow curve against your demand, not a single number. Choose the drain to suit access: automatic (this unit) suits enclosed or infrequently attended installations; manual suits attended stations; differential-pressure is the default. Choose 5 um (this unit) where downstream valves and instruments need finer filtration than the 40 um standard element. The gauge here is the external round type scaled in MPa; square embedded gauges and psi or bar scales are alternatives. Thread: PT is the standard, with G (BSPP) and NPT (this unit) as catalogue options to order. A bracket is included; a J-code variant omits it.
Flow for this family is published as curves, not a single rated figure, so we do not quote one. Send us your line demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 sizing from the datasheet on request before you order.
The A in the code sets the automatic drain, which discharges condensate from the bowl without manual attention - useful where the unit is mounted in an enclosed panel or an infrequently visited part of the plant. The W sets the 5 um filter element, one grade finer than the 40 um standard, for downstream equipment that needs cleaner air. Both are order-time choices across the GFR range.
