The AirTAC GFR60020LJC3T AirTAC Filter Regulator 3/4 NPT 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 GFR60020LJC3T 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, and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential across the element rises. Because the bowl is aluminium alloy (the material used at size 600), the unit suits installations where a polycarbonate bowl would not be preferred. It is the low-pressure type (code L), fitted with a round pressure gauge scaled in bar, and supplied without a mounting bracket. 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 can be ordered with automatic or manual drain, a 5 um element (code W), square or round gauges scaled in MPa, psi or bar, PT, G or NPT threads, and with or without a bracket. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application on request.

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.

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.

On a stamping or forming press fed from a plant air ring main, this 3/4 in filter regulator cleans the supply of water and scale and holds a steady low-pressure setting to the cylinder valves, so stroke force stays repeatable through the shift.
In a paint or coating booth where atomizing and conveying air must run well below standard line pressure, the low-pressure type regulator gives fine control at reduced settings while the 40 um element keeps oil-free, dry air reaching the gun.
On a bottling or packaging line driving grippers, diverters and pusher cylinders, the unit filters condensate out of the 3/4 in trunk feed and regulates it to the pressure the actuators were designed for, with the differential drain clearing water without operator attention.
Start with the port and size: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range - match it against the pipe size and air demand of the circuit, and step down to 200/300/400 if the flow curves allow a smaller body. Drain choice matters: this configuration uses the differential-pressure drain (the default); automatic (code A) or manual (code M) drains can be ordered instead. Filtration grade is the standard 40 um; specify 5 um (code W) if downstream equipment needs finer air. The gauge here is the external round type scaled in bar; embedded square gauges and MPa or psi scales are alternatives. Threads are PT as standard, with G and NPT as order options - this unit carries NPT. A bracket can be added if the code J (no bracket) does not suit your mounting. Note that this is the low-pressure type (L); its exact adjustment range is not published in the material we hold, so confirm it with us. 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 l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow curve and correct sizing from the datasheet on request.
L marks the low-pressure type of regulator. It is intended for circuits that run at reduced pressure settings rather than the standard range. The exact adjustment range for the low-pressure type is not published in our current material, so please confirm it with us before ordering. Everything else in this code decodes as: 3/4 in NPT port, 40 um element, differential-pressure drain, round gauge scaled in bar, no bracket.
