The AirTAC GFR600C20MLF2W AirTAC Filter Regulator PT3/4, 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 GFR600C20MLF2W is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a PT3/4 port with PT (BSPT-type) thread, a fine 5 um filter element (code W), a manual drain for periodic bowl purging, and the low-pressure regulator type for circuits that run below standard line pressure. An embedded square gauge with a psi scale is fitted, the metal bowl is aluminium alloy at size 600, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge scale options, and G or NPT thread variants to order. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures for your application 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.

Filtering and regulating supply air to a pneumatic press or forming actuator that is specified to run below standard shop-air pressure, with the 5 um element keeping debris out of the cylinder seals.
Conditioning air for clamp and hold-down cylinders on a packaging conveyor, where clean, regulated low-pressure air holds product without crushing and the manual drain is emptied during shift checks.
Supplying filtered, regulated pilot air to automated process valves on a plant skid, with the square psi gauge giving operators a local reading of the set pressure.
Start with the port step: size 600 with a 3/4 inch PT port suits lines plumbed at 3/4 inch, and the right size depends on the flow your circuit needs - because flow is published as curves rather than one rated figure, ask us to confirm sizing against your application before ordering. Choose the drain to match access: manual drain (this unit) needs someone to open it periodically, while automatic and differential-pressure drains purge themselves. The 5 um element (code W) is the finer choice over the 40 um standard when downstream equipment is sensitive to particulate. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are catalogue options. PT thread is standard on this model, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
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 this series as curves rather than a single rated figure, so no single flow number can be quoted honestly. Tell us your application and required flow, and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects a manual drain: someone opens it periodically to purge collected water from the aluminium alloy bowl. If you cannot guarantee that routine, the same size 600 GFR is available with an automatic drain (code A) or the default differential-pressure drain - just ask for the alternative model code.
