The AirTAC AirTAC GFR600C20ALJF2WGK Filter Regulator G3/4 5 um 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 AirTAC GFR600C20ALJF2WGK is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 (BSPP) port, a 5 um filter element (the fine grade; 40 um is the standard option), an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator type for circuits that run well below standard line pressure. The embedded square gauge reads in psi, a reverse/check valve is fitted to hold downstream pressure, and the unit ships without a mounting bracket. At size 600 the 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 spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or external round gauges in MPa, psi or bar scales, PT, G or NPT threads, and bracket or no-bracket mounting. Flow for this series is published as curves rather than a single rated figure, 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 packaging line where sealing bars, clamp cylinders and hold-downs run at reduced pressure, this filter regulator cleans the shop air to 5 um, holds the reduced setpoint, and its automatic drain keeps condensate out of the valves between shifts. The check valve holds the downstream circuit if supply dips.
Test benches and analytical instruments with air-fed sensors and actuators need clean, steady, low-pressure air. The 5 um element protects sensitive components from particulate and water, the low-pressure regulator type suits reduced setpoints, and the psi gauge lets technicians verify the setting at a glance.
Feeding diverters, stoppers and hold-down clamps along a conveyor line, this unit combines filtration and regulation at one G3/4 take-off point. The automatic drain handles condensate from long runs of main line, and the reverse/check valve keeps the actuators pressurised during upstream interruptions.
Step up or down through the GFR sizes (200/300/400/600) and their port sizes (1/8 to 1 inch) according to the air demand of your circuit; this unit is the largest step, with a G3/4 port. Choose the drain to suit attendance: automatic (as here) for unattended duty, manual where an operator drains routinely, or the differential-pressure default. Choose 40 um for general protection or 5 um, as specified here, where downstream valves and instruments need finer air. Gauges are embedded square as standard with optional external round gauges in MPa, psi or bar; this unit reads psi. PT is the standard thread, with G (BSPP) and NPT available as order options - this code is the G version. Brackets are optional; this configuration omits one. Note this is the low-pressure regulator type, intended for circuits running well below standard regulated pressure; its exact adjustment range is not published in the material we hold, so confirm it with us against your setpoint. Flow is published as curves, not 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 characteristic curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The L code in this model marks the low-pressure regulator type, intended for circuits that run well below standard regulated pressure, unlike the standard GFR type. Its exact adjustment range is not published in the material we hold, so confirm your setpoint with us and we will verify suitability from the datasheet on request.
