The AirTAC GFR600C20LJF3WT AirTAC Filter Regulator NPT3/4 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 GFR600C20LJF3WT is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built around a 3/4 in NPT port and a 5 um filter element, the finer of the two published grades. The drain is the differential-pressure type, which discharges collected condensate as the pressure differential across the element rises, and the regulator is the low-pressure (L) type, intended for circuits that run well below the 1.0 MPa (145 psi) maximum inlet; its exact adjustment range is not published, so confirm it with us. An embedded square gauge with a bar scale is fitted, the 600-size bowl is aluminium alloy rather than polycarbonate, no mounting bracket is included, and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and each unit can be ordered with a 40 um standard or 5 um (W) element, a differential-pressure, automatic or manual drain, an embedded square gauge or an optional external round gauge with MPa, psi or bar scales, and PT, G or NPT threads. Flow for these units is published as curves rather than a single rated figure, so send us your application and we will confirm sizing and the full datasheet 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. 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.

Air prep ahead of quarter-turn actuators and solenoid valves on a low-pressure control circuit: the 5 um element keeps seat and seal contamination down while the regulator holds the actuator supply steady.
Feeding forming, sealing and clamp cylinders on a packaging line that runs at reduced pressure; the aluminium alloy bowl and differential-pressure drain handle condensate through continuous shifts.
Supplying test benches and pilot rigs where the air must be both clean (5 um) and held at low regulated pressure, with a bar-scale square gauge for direct local reading.
The real choices on this family: step up or down a size (200/300/400/600) to match the port and the flow your line needs; pick the drain - differential-pressure (as here, self-acting), automatic, or manual; choose the 40 um standard element or the finer 5 um W grade fitted on this unit; and set the gauge scale to MPa, psi or bar. Thread is PT as standard, with G and NPT as order options - this unit carries NPT. The low-pressure (L) regulator type suits circuits that run well below the 1.0 MPa (145 psi) inlet maximum, and its exact adjustment range is not published, so confirm it with us. Flow is published as curves, not a single rating, so 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and port size and we will confirm the sizing from the datasheet on request.
The W code fits the 5 um element instead of the 40 um standard, for finer water and particulate removal. The L code makes the regulator the low-pressure type for circuits running well below the 1.0 MPa (145 psi) inlet maximum; its exact adjustment range is not published, so confirm it with us. Thread is NPT on this unit; PT is standard and G is also an order option.
