The AirTAC GFR60020LC1WT AirTAC Filter Regulator NPT3/4 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 GFR60020LC1WT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is built for 3/4 in NPT ports, carries the finer 5 um filter element (code W) instead of the standard 40 um, and drains collected condensate by differential pressure. It is the low-pressure regulator type, fitted with an external round gauge reading in MPa, and its aluminium alloy bowl suits the larger 600-size installations. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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 for manual or automatic drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, G or NPT threads, and a reverse/check valve. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet figures 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.

| (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. |

| C | Gauge shape: Round. C is round, F is square. |

| 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.

Conditions and regulates air feeding the low-pressure actuator circuits on a carton-forming and sealing section, with the 5 um element protecting downstream valves from water and fine particulate.
Provides clean, regulated low-pressure air to instruments and pneumatic test rigs on a lab bench, where the round MPa gauge gives a clear direct pressure readout at the point of use.
Feeds the gate and stopper cylinders along a bottling conveyor, combining water and particle removal with steady low-pressure regulation in a single 3/4 in body.
Size and port set the capacity: this unit is the largest GFR600 step with a 3/4 in NPT port, and you can step down through sizes 200, 300 and 400 to match smaller lines. Choose the drain: differential-pressure (standard, as fitted here), automatic (code A) or manual (code M). Choose the element: 40 um standard or 5 um (code W, as fitted here). Gauges are an embedded square type or an external round gauge, in MPa, psi or bar scales; this unit carries a round MPa gauge. Thread is PT as standard with G and NPT as order options, and a mounting bracket is included. Because flow is published as curves rather than 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 the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet and check the sizing of this unit against your required flow before you order.
The L marks the low-pressure regulator type, intended for circuits regulated below the standard range; the exact range for this variant is not published, so ask us to confirm it. The rest decodes as: size 600, 3/4 in NPT thread, C1 = external round gauge with MPa scale, W = 5 um filter element, differential-pressure drain, and a mounting bracket included.
