The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 in PT, 5 um, psi 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 GFR600-20 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit is specified with a 3/4 in PT port, a 5 um filter element (the finer of the two available grades), a differential-pressure drain that bleeds accumulated condensate automatically as pressure drops across the element, and a fitted reverse/check valve that holds downstream pressure when the upstream supply is lost. The embedded square gauge reads in psi, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, psi/MPa/bar gauge scales, G or NPT thread options and an optional mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers 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.

Filtering and regulating the shop-air feed to a CNC machining centre's pneumatic tool-changer and clamping circuits, with the 5 um element and check valve protecting spool valves from particles and pressure dips.
Conditioning the 3/4 in main air drop that feeds a packaging line's bagger and case-erector cylinders, holding a steady regulated pressure so sealing and forming strokes stay repeatable.
Supplying clean, regulated air to the diverter gates and stop cylinders on a warehouse conveyor sorting system, where the check valve keeps gates in position during brief compressor unload events.
Step up or down the GFR size ladder (200/300/400/600) to match the port and flow band your line needs; this 600 unit takes a 3/4 in PT port, and G or NPT threads are order options if your pipework calls for them. The 5 um element (code W) suits air that feeds sensitive valves, cylinders or instruments; the standard 40 um grade is fine for general shop-air protection. The differential-pressure drain on this unit needs no timer or operator attention, but if your compressor cycles lightly or you want positive purging, ask about the automatic or manual drain variants. The fitted reverse/check valve keeps the regulated side pressurised through brief supply interruptions. If you prefer an external round gauge or a different scale (MPa or bar), those are configurable. Flow for this series is published as curves, not a single rating, so send us your flow and pressure requirements 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. The reflux valve permits reverse flow 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 one number. Tell us your inlet pressure, set pressure and required flow, and we will confirm the sizing against the datasheet on request before you order.
The code JF2WK decodes a 5 um filter element (the finer W grade, versus the standard 40 um), a square gauge scaled in psi, and a fitted reverse/check valve (K). The 5 um element gives cleaner air for sensitive downstream components, and the check valve holds downstream pressure if the upstream supply drops. This configuration has no lubricator; for lubrication you would add a GL unit or step up to a GFC or GC combination.
