The AirTAC GFR60020ALC2WK AirTAC Filter Regulator 3/4 in PT 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 GFR60020ALC2WK 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 the low-pressure type, fitted with a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, and an external round gauge reading in psi. A reverse/check valve is fitted, and the mounting bracket is included. The 3/4 in PT port suits larger supply lines, and because this is the 600 size the bowl is aluminium alloy.
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 differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure against 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.

|---|---|
| 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. |

| C | Gauge shape: Round. 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.

Feeding filtered, regulated air at reduced pressure to carton-sealing and wrapping heads on a packaging line, where the low-pressure type matches circuits run below standard operating pressure and the automatic drain keeps condensate off the actuators.
Mounted ahead of a bank of directional valves and cylinders on a machine frame, cleaning the air to 5 um and holding a steady low set pressure so valve spools and cylinder seals are not fouled by water or fine particulate.
Supplying blow-off nozzles and cleaning jets along a conveyor line, where the 3/4 in port supports multiple drop points and the reverse/check valve plus automatic drain keep the downstream circuit stable between shifts.
Choose the size by the port and flow your line needs: this unit is size 600 with a 3/4 in PT port, the larger end of the range. Drain type is a real decision - automatic (as here) empties the bowl without operator input, manual requires periodic draining, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard or 5 um (code W, as fitted here) when finer particulate protection matters. Gauges are offered as the embedded square type or an external round gauge, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated figure, so we cannot quote a number here. Send us your application details and we will confirm the flow and any datasheet figure 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 family as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your line pressure, port size and downstream demand, and we will confirm the flow from the datasheet for this exact model before you order.
The L code marks the low-pressure regulator variant, intended for circuits run at reduced pressure; the exact adjustment range for this type is not published on our sheet, so ask us to confirm it. The A code means the bowl drains automatically, expelling collected condensate on its own instead of waiting for a manual drain - useful on lines that run unattended. This unit also carries the 5 um (W) element, a round psi gauge and a reverse/check valve.
