The AirTAC GFR600C20LJC2T AirTAC Filter Regulator 3/4 in NPT 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 See datasheet 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 GFR600C20LJC2T is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates the pressure delivered downstream. This size 600 unit has a 3/4 in NPT port, a 40 um standard filter element and a differential-pressure drain, which vents collected condensate from the aluminium alloy bowl automatically as the pressure drop across it rises. It is the low-pressure (L) regulator type, fitted with an external round gauge reading in psi, and is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR series covers sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um element (code W), an embedded square gauge as standard or an external round gauge in MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the sizing and regulation figures from the datasheet 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Point-of-use preparation at automotive and machine-assembly stations: the filter stage strips water and pipe scale before it reaches impact wrenches and nutrunners, while the regulator holds a steady, gentle supply pressure for low-pressure tool circuits on a 3/4 in drop.
Feeding spray guns and coating applicators that call for modest, closely held pressures: the 40 um element keeps oil- and water-carryover particulates out of the finish, and the low-pressure regulator type is matched to circuits that never run near full line pressure.
A compact filter-regulator stage ahead of directional control valves and small actuators on process and packaging skids, keeping condensate out of valve seats and holding a stable setpoint so cylinder and valve timing stays repeatable.
The real choices in this family are the size and port step (200/300/400/600, 1/8 in to 1 in) matched to the air demand of your line; the drain type (differential-pressure as here, automatic, or manual); the filter element (40 um standard, 5 um with code W); the gauge (embedded square as standard, external round optional, in MPa, psi or bar); the thread (PT standard, G or NPT to order); and whether a bracket is needed - this unit is supplied without one. As the low-pressure type, its regulation range differs from the standard version and is not published as a single figure, so confirm it with us. Flow is published as curves, not one rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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, required downstream pressure and air demand, and we will confirm the sizing from the datasheet on request before you order.
The L marks the low-pressure regulator type: its adjustment range differs from the standard version and is not published as a single figure, so we confirm the exact range from the datasheet on request. The other letters decode as: 600 size, 20 = 3/4 in port, T = NPT thread, J = no bracket, C2 = round gauge with psi scale; with no drain letter, the differential-pressure drain is fitted as the default.
