The AirTAC GFR600C20MLJF2WGK AirTAC 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 GFR600C20MLJF2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in one body. This configuration is built for larger 3/4 in (G3/4) lines and carries the 5 um filter element (code W) for finer air than the standard 40 um grade, a manual drain for controlled bowl evacuation, an embedded square gauge reading in psi, and a fitted reverse/check valve. It is the low-pressure type, and the bowl on size-600 units is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -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 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, gauge and scale options, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding filtered, low-pressure regulated air to spray stations on a paint line: the 5 um element helps keep water and particles out of the finish, the psi gauge lets operators verify set pressure at a glance, and the manual drain suits a booth serviced each shift.
Supplying regulated air to cylinder-driven gates and stops along a bottling or packaging conveyor, where the check valve blocks backflow through the unit and the 3/4 in G-thread port matches the main drop leg feeding the section.
Providing clean, low-pressure regulated air to a laboratory or QC test bench running pneumatic fixtures, with the aluminium-alloy bowl and manual drain giving straightforward visual checks and controlled evacuation between test sessions.
Size 600 with a G3/4 port is the right step when your line is plumbed in 3/4 in and your flow demand sits at the upper end of the G-series range; step down to 300 or 400 for smaller ports and lighter duty. This unit already carries the finer 5 um element - choose 40 um where only coarse water and particle removal is needed. The manual drain suits attended installations where an operator can bleed the bowl on a routine; pick automatic or differential-pressure drain for unattended duty. The square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread here is G (BSPP) at G3/4 - PT is the catalogue standard, with G and NPT as order options - and this code omits the mounting bracket. Regulation is the low-pressure type; its exact adjustment range is not published in the data we hold. Because flow is published as curves rather than a single rated figure, 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 curves rather than a single rated figure, so we do not quote a flow number. Tell us your line pressure and demand and we will confirm the sizing from the datasheet curves on request before you order.
Manual drain means an operator opens the bowl drain to expel collected water, which suits attended installations on a regular service routine; automatic and differential-pressure drains are available on other codes. This unit is the 5 um grade (finer than the standard 40 um), has a G3/4 port with G (BSPP) thread - PT is the catalogue standard and G/NPT are order options - and includes a square gauge reading in psi.
