The AirTAC GFR60020LF3T AirTAC NPT 3/4 Filter Regulator 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 GFR60020LF3T is an AirTAC GFR series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit has a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain, and the low-pressure regulator type. The embedded square gauge reads in bar, the 600-size bowl is aluminium alloy, and a mounting bracket is included. 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 in to 1 in, and options include a 5 um element (code W), automatic or manual drains, PT, G or NPT threads, and gauge scales in MPa, psi or bar. Flow for this series 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.

| (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. |

| F | Gauge shape: Square. 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.

Point-of-use conditioning ahead of directional valves and pneumatic cylinders on a machine's air preparation line: the 40 um element strips water and particles while the regulator holds the working pressure the circuit was set to.
Feeding filtered, regulated air to packaging machinery actuators and grippers, where a single-body filter regulator saves panel space and the bar-scale square gauge gives operators a direct local pressure readout.
Conditioning shop air for laboratory benches and test rigs that need clean air at a stable setpoint, with the low-pressure regulator type selected for circuits that hold a reduced regulated pressure.
Match the size and port to your air demand: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The L in this code selects the low-pressure regulator type rather than the standard type; its exact adjustment range is not published in our data, so confirm your required setpoint with us. Other real choices: drain type (differential-pressure here, automatic or manual available), filter grade (40 um standard, 5 um with code W), gauge scale (this unit reads bar; MPa and psi scales exist), thread (PT is the standard, G and NPT are order options), and bracket (included on this code).
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 rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure and air demand and we will confirm the flow curve and sizing from the datasheet on request.
The L marks the low-pressure regulator type, a distinct variant from the standard type. Its exact adjustment range is not published in our data, so confirm the setpoint you need with us before ordering. Everything else decodes normally: 3/4 in NPT port, 40 um element, differential-pressure drain, square bar gauge, aluminium bowl and included bracket.
