The AirTAC GFR60020LJC1T 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 AirTAC GFR60020LJC1T is a size 600 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration carries a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a fitted external round gauge scaled in MPa for direct downstream pressure setting. It is the low-pressure (L) type, intended for circuits that must be regulated below the standard range, and it is supplied without a mounting bracket. The size 600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um (W) filtration, gauge style and scale, thread (PT standard; G and NPT as order options), bracket and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow figures 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.

Feeds filtered, regulated air to carton-sealing and wrapping heads on a packaging line that runs at reduced downstream pressure, with the MPa gauge letting operators set and verify the setting at the machine.
Sits ahead of a fixture-clamping circuit on a CNC or manual machining cell, removing water and pipe scale from the shop air while holding the lower clamping pressure the low-pressure type is built for.
Installed at the take-off of a 3/4 in plant air header to condition and regulate air for a downstream valve manifold or actuator bank, with the differential-pressure drain handling condensate in continuous flow.
Size and port are the first choice: 600 is the largest GFR frame, and this unit takes a 3/4 in port, so size the frame against the air demand of the circuit - larger frames carry larger ports and higher flow capacity, which we can confirm from the curves before you order. This unit is the low-pressure (L) type; its exact regulation range is not published in the material we hold, so confirm the required downstream pressure with us before ordering. The drain here is differential-pressure (the default); automatic (A) and manual (M) drains are available on other codes. Filtration is the standard 40 um element; specify a W code if the circuit needs 5 um. The gauge fitted is the external round type scaled in MPa; embedded square gauges and psi or bar scales are alternatives. Thread is NPT on this code (PT is the standard; G is also an order option), and no mounting bracket is included - a J code - so plan your own mounting. Flow is published as curves, not a single rating, so 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 rated flow number for this unit. Tell us your inlet pressure and the air demand of the circuit and we will confirm the sizing against the datasheet curves on request before you order.
The L in the code makes this the low-pressure regulator type, intended for circuits that must be regulated below the standard range; the exact range for the low-pressure type is not published in our material, so confirm your required downstream pressure with us. Everything else decodes normally: 3/4 in NPT port, 40 um filtration, differential-pressure drain, aluminium alloy bowl on this size 600 frame, round MPa gauge fitted, and no mounting bracket.
