The AirTAC GFR60020LC3T AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR60020LC3T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in one body. This 600-size unit comes with 3/4 in NPT ports, a 40 um standard filter element, differential-pressure drainage, the low-pressure regulator type, and an external round gauge scaled in bar. The bowl on this size is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scale options, and G (BSPP) or NPT thread variants alongside the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

| 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeds filtered, pressure-controlled air to the gripper and pusher cylinders on a bottling line, with the low-pressure type holding gentle setpoints for delicate handling at the filler head.
Conditions the air feeding a machining-centre clamping manifold: water and chips are drained out of the bowl and the regulator holds a steady clamp pressure so workholding does not drift during a cycle.
Supplies clean, regulated air to the flap-fold and taping cylinders of a packaging conveyor, with the 3/4 in ports carrying the volume a multi-station sealer draws.
Size the unit by the flow your circuit needs: 600 is the largest GFR frame and carries 3/4 in ports, so step down to 300 or 400 if demand is smaller. Keep the 40 um standard element for general protection or order the 5 um W option for finer filtration. Drainage here is differential-pressure (the bowl bleeds down as system pressure drops); automatic (A) and manual (M) versions exist if you prefer. The L in this code marks the low-pressure regulator type, which sets lower downstream pressures than the standard version - its exact range is not published, so confirm it with us. The gauge is the external round type scaled in bar; MPa and psi scales are available. Thread is NPT on this unit; PT is the AirTAC standard and G (BSPP) can be ordered. Because flow is published as curves rather than a single rating, ask us to check 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 this family as curves, not as a single rated figure, so we do not quote a number here. The 600 size is the largest GFR frame with 3/4 in ports, and we will confirm the exact flow figures from the datasheet against your application on request before you order.
L marks the low-pressure regulator type, which sets lower downstream pressures than the standard version; its exact adjustment range is not published, so confirm it with us. Drainage is differential-pressure: the bowl bleeds accumulated water as system pressure drops at shutdown, with automatic (A) and manual (M) drain versions available in the family.
