The AirTAC GFR60020LJF2WT AirTAC Filter Regulator, NPT3/4, 5 um 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 GFR60020LJF2WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, and a low-pressure regulator type for circuits set below the standard range. An embedded square gauge reading in psi is fitted so the setpoint is visible at the unit, and the aluminium alloy bowl suits this largest size in the series. No mounting bracket is included with this code.
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 is orderable with 40 um or 5 um filtration, manual, automatic or differential-pressure draining, PT, G or NPT threads, MPa, psi or bar gauge scales, and a reverse/check valve option. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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. 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.

Clamping cylinders on a press line often hold at pressures below the main header setting. This low-pressure filter regulator lets the clamp circuit be set independently, with the 5 um element protecting the clamp valve from water and fine debris carried in the shop air.
Stopper and gate cylinders on a bottling conveyor cycle constantly and are sensitive to condensate carry-over. A 3/4 in filtered supply with automatic differential-pressure draining keeps water out of the cylinders and the valve manifold without an operator draining bowls each shift.
Looms and auxiliary air jets on a weaving floor run from a large-diameter main that benefits from the size-600 port. Filtering to 5 um ahead of the jets and regulating the jet header at a low setpoint helps keep nozzle circuits stable, with the psi gauge giving operators a visible setpoint.
Start with the port step: this unit is the 3/4 in NPT version of the size-600 body, the largest in the GFR range, so match it to the main air line feeding your circuit. Choose the 5 um element (this code) when downstream valves, cylinders or instruments need finer protection than the 40 um standard; note the finer element loads faster, which is where the differential-pressure drain on this unit earns its keep by clearing condensate as the element restricts. The low-pressure regulator type on this code is intended for setpoints below the standard range - confirm the exact range with us before ordering. The fitted square gauge reads psi; MPa and bar scales are orderable alternatives, and an external round gauge is optional. PT is the standard thread and G or NPT are order options, so order the thread your pipework actually uses. Because flow is published as curves rather than a single rating, send us your flow requirement 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 rather than a single rated figure, so we do not quote a number here. Tell us your required flow and line conditions and we will confirm the datasheet curve for this 3/4 in size-600 unit against your application before you order.
The code decodes W (5 um filtration, the finer of the two published grades - 40 um is standard) and a blank drain position (differential-pressure, which discharges condensate automatically as the element loads). Together they suit circuits with sensitive downstream components where you want finer filtration without manual draining; a manual-drain version is available if you prefer a controlled drain point.
