The AirTAC GFR60020LJC1WT AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60020LJC1WT is a size-600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate down to 5 um (the fine W-grade element, versus the 40 um standard) and regulates downstream pressure in a low-pressure type configuration. The 3/4 in NPT port suits larger, higher-demand supply lines. This unit is fitted with a round external pressure gauge scaled in MPa, uses the differential-pressure drain (default) that bleeds condensate automatically as flow passes through, and has an aluminium alloy bowl - the material used at size 600. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600, with choices of port and thread (PT standard, G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, and bracket availability. Flow figures for this series are published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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.

A low-pressure filter regulator ahead of a robot cell's gripper and clamp circuit: the 5 um element protects directional valves and cylinders from water and fine particulate, while the regulator holds the gentle pressure delicate handling needs. The round MPa gauge lets a technician read the set point at a glance.
On a packaging line's 3/4 in main drop feeding case erectors and sealers, this unit filters the shop air to 5 um and regulates it to the low pressure the sealing cylinders run at, with the differential-pressure drain shedding condensate as production flows.
Instrument and pilot-air circuits on a plant floor need clean, steady, moderate-pressure air. This filter regulator conditions the supply line, the fine element guards positioner internals, and the MPa-scaled gauge documents the regulated set point during commissioning checks.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs - this is the 600 size with a 3/4 in NPT thread. Choose the drain: differential-pressure (this unit, automatic in operation), fully automatic, or manual. Choose the element: 40 um standard or 5 um fine grade (this unit, code W) where downstream equipment needs cleaner air. Gauge style and scale are selectable - this configuration carries a round external gauge on the MPa scale; psi and bar scales are also catalogue options. Thread is selectable between PT (standard), G (BSPP) and NPT (this unit), and a bracket can be ordered where this unit omits it. For regulation: this is the low-pressure type; the exact adjustment range for the low-pressure variant is not published in our sheet, so ask us to confirm it against your set pressure. 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet curves on request.
Yes. PT is the standard thread for the GFR series, and G (BSPP) and NPT are catalogue options you select when ordering. The trailing T in GFR60020LJC1WT is what specifies the 3/4 in NPT port on this model; the same size is available in the other threads.
