The AirTAC GFR60020LC2WG AirTAC Filter Regulator G3/4 Low-Pressure 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 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 GFR60020LC2WG is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built in the largest G-series size with a G3/4 (BSPP) port, carries the 5 um filter element (code W) for finer filtration than the 40 um standard element, and is the low-pressure regulator type for circuits that run at reduced supply pressure. The differential-pressure drain bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and the fitted round gauge reads downstream pressure in psi. 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 to 1 inch, and options include manual or automatic drains, the 40 um standard or 5 um fine element, square (embedded) or round gauges with MPa, psi or bar scales, a reverse/check valve, 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.

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". |
| (blank) | Drain: Differential-pressure 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. |
| G | G (BSPP) 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.

Feeding clean, regulated low-pressure air to the clamp and pusher cylinders on a carton-forming and sealing line, with the 5 um element protecting directional valves from water and fine contamination.
Conditioning shop compressed air for a test bench or lab rig that runs at reduced pressure, where the fine 5 um grade and a psi-reading gauge keep the circuit visible and the air clean.
Supplying regulated air to blow-off nozzles and cleaning jets along a conveyor line, with the differential-pressure drain handling condensate and the aluminium 600-size bowl standing up to continuous duty.
Size and port: GFR600 is the largest step in the family, with a G3/4 port suited to higher air demand; step down to GFR200/300/400 if your line flow is modest. Filtration: this unit carries the 5 um element (code W) - choose it when downstream valves or instruments need finer air than the 40 um standard element provides. Drain: the differential-pressure drain is fitted here; a manual drain (code M) or automatic drain (code A) can be ordered instead. Gauge: the round external gauge with psi scale is fitted; embedded square gauges with MPa, psi or bar scales are the alternative. Thread: this unit is G (BSPP); PT is the catalogue standard and NPT is available to order. A mounting bracket is included.
Sizing honesty: AirTAC publishes flow for this family as curves, not as a single rated number, and the exact regulation range of the low-pressure type is not stated on the sheet we work from. Ask us to confirm flow and regulation figures against your application 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 GFR family as performance curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow curve and correct sizing from the datasheet on request.
The L in GFR60020LC2WG marks the low-pressure regulator type, intended for circuits that run at reduced supply pressure rather than full line pressure. The exact adjustment range for this type is not published on the sheet we work from, so ask us to confirm it from the datasheet before ordering.
