The AirTAC GFR600C20LJF2 AirTAC Filter Regulator PT3/4 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 GFR600C20LJF2 is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with 3/4 in PT ports. This configuration is the low-pressure type, fitted with the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge reading in psi. The aluminium alloy bowl is standard at size 600, and this unit is ordered 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 is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, thread form (PT standard, G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

On a spray or coating line, this unit filters water and debris from the shop air and holds a gentle, stable regulated pressure to the guns, protecting finish quality where high supply pressure would overspray.
Feeding cylinders and actuators on a carton or bag packaging conveyor, the combined filter and regulator keeps condensate and particulate out of the valves while holding the lower working pressure the actuators need.
On pneumatic clamps and workholding fixtures at a machining centre, this unit cleans the incoming air and regulates it to the pressure the fixture designer specified, with the psi gauge giving the operator a direct setpoint readout.
Start with the port step: size 600 with 3/4 in PT ports is the largest GFR frame, so match it to lines where higher supply volume is expected and confirm against the flow curve before ordering. The low-pressure type (code L) is the right choice where the regulated setpoint sits well below standard ranges; the exact range for this variant is not published in the summary data, so confirm it with us against your setpoint. Drain is differential-pressure as standard here - choose automatic (A) for unattended drains or manual (M) where you want operator control. Filtration is the 40 um standard element; specify W if the downstream equipment needs 5 um. The square gauge is fitted and reads in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available to order, and this unit comes without a bracket (add one if you mount away from a manifold). Flow is published as curves, not a single rating, so send us your application conditions and we will confirm sizing 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 number, so we do not quote a figure here. Tell us your line pressure, setpoint and expected air demand and we will confirm the sizing against the datasheet curve before you order.
The L in the code marks the low-pressure regulator variant, intended for applications where the regulated pressure is set well below the standard range; the exact range for this variant is not in the published summary, so confirm your setpoint with us. The drain is differential-pressure: condensate collected in the aluminium bowl is expelled automatically by the pressure differential during normal flow, with no manual draining needed.
