The AirTAC GFR600C20LJC1T 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 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 GFR600C20LJC1T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure 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 accumulated condensate automatically whenever the pressure differential across the element is high enough. It is a low-pressure type regulator, fitted with an external round gauge scaled in MPa, and no mounting bracket is included. The metal bowl on this 600 size is aluminium alloy. 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 port sizes from 1/8 in to 1 in, and options including manual or automatic drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow for this model is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures 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. 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.

On a CNC machining cell where pneumatic clamps and swing cylinders are designed to run at reduced line pressure, this filter regulator cleans the shop air, holds the reduced setpoint steady, and shows the setting on the MPa gauge at the 3/4 in main drop.
At the 3/4 in supply header of a cartoning or wrapping machine, the unit strips water and pipe scale from the plant air supply, protects downstream valves and actuators from contamination, and lets the set-up technician read and adjust the working pressure in MPa.
On a skid where diaphragm-actuated process valves are piped for a reduced supply pressure, the low-pressure type regulator gives finer control in the reduced band, the 40 um element keeps the positioner air clean, and the differential-pressure drain keeps condensate out of the loop.
Size 600 with a 3/4 in port is the step to choose when the line's required flow and pipe size call for the largest of the four GFR frames; the smaller 200/300/400 sizes use the same body concept with smaller ports. This unit is the low-pressure type, so if your circuit must hold a setpoint in the upper part of the standard range, confirm suitability with us first - the exact adjustment range for the low-pressure version is not published and we will confirm it on request. The 40 um element is the standard grade; specify the W suffix if the application needs 5 um filtration. Drain here is differential-pressure (self-bleeding); automatic (A) and manual (M) drains are order options. The round MPa gauge is fitted on this code; square gauges and psi or bar scales are alternatives. Thread is NPT on this unit, with G (BSPP) and PT available to order, and no mounting bracket is included (bracket optional).
Because catalogue flow is given as curves and not a single rated figure, we do not quote a flow number here. Send us your application's 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, not as a single rated figure, so we do not quote a flow number on the page. Tell us your line's flow and pressure requirements and we will confirm the sizing against the datasheet on request before you order.
The L in the code marks this as the low-pressure regulator type rather than the standard one, intended for reduced working pressures. The exact adjustment range for the low-pressure version is not published in the material we hold, so please confirm the range for your setpoint with us on request. The fitted round gauge is scaled in MPa; psi and bar scales are available as order options.
