The AirTAC GFR600C20LJF2WT AirTAC Filter Regulator NPT3/4 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 GFR600C20LJF2WT is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built for 3/4 in NPT ports, carries the fine 5 um filter element (code W) instead of the standard 40 um, drains condensate by differential pressure, and houses the element in an aluminium alloy bowl, which is the material used across the 600 size. The regulator is the low-pressure type, and the fitted embedded square gauge reads in psi. 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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Conditioning the 3/4 in main air feed to a stamping or forming press, where the fine 5 um element protects press cylinders and control valves from water and particulate carryover and the low-pressure regulator holds a modest, stable working set point.
Filtering and regulating the plant-air drop feeding the actuator bank on a cartoning or case-packing line, with the psi square gauge giving operators a direct local reading and the differential-pressure drain keeping condensate off the machine grid.
Supplying cleaned, regulated low-pressure air to bench-top test rigs, pneumatic fixtures or pilot circuits in a lab or QC cell, where the 5 um grade and psi-scaled gauge support repeatable, closely watched set points at the 3/4 in supply.
Step through the decodable choices in order. Size 600 with 3/4 in ports sits at the top of the GFR range, so match it to the largest air demand in your line; smaller sizes 200-400 step down through 1/8 to 1/2 in ports. This code takes the 5 um element - choose it when downstream valves, cylinders or instruments need finer filtration than the standard 40 um; the differential-pressure drain then bleeds collected condensate automatically as flow passes through, with no manual draining routine. The low-pressure regulator type suits circuits with modest set pressures; its exact adjustment range is not published, so confirm it with us before ordering. The square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread here is NPT, with PT standard and G (BSPP) as order options. Brackets are optional on this code - none is fitted.
One honest note before you order: AirTAC publishes filter-regulator flow as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet.
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 GFR600 as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your working flow and pressure and we will confirm the sizing against the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits with modest set pressures; its exact adjustment range is not published, so confirm it with us. The W marks the 5 um filter element instead of the standard 40 um, giving finer particulate removal. Both are fixed in this code - if you need the standard grade or the standard regulator type, order a different GFR600 variant.
