The AirTAC GFR60020AF2W AirTAC Filter Regulator PT3/4, 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 automatic 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 GFR600-20AF2W is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 3/4 in PT port, a 5 um filter element (one step finer than the 40 um standard), an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge reading in psi. The pressure adjustment range is 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). Because this is the 600 size, the bowl is aluminium alloy, and the unit operates from -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, and can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, MPa, psi or bar gauge scales, PT, G or NPT threads, and with or without a bracket. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow figures 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.

Installed at the take-off from a plant air header, it filters water and particles from the 3/4 in branch line and holds a steady regulated pressure to the packaging machines below.
Mounted ahead of the valve manifold feeding conveyor cylinder banks, it cleans the supply with the 5 um element and keeps actuator pressure within the set range, with the automatic drain handling condensate.
Fitted on the air drop supplying panel-mounted pneumatic controls on a process skid, it delivers filtered, regulated air at the set pressure, with the psi gauge giving a local reading at the panel.
Start with the port and size step: 600 is the largest GFR frame, and here it carries a 3/4 in PT port, so size it against the air demand of the line it feeds. Choose the drain to match access: automatic (this unit) suits installations that are not checked daily; manual drain suits attended points; the differential-pressure default drains on a pressure differential. Pick 5 um (this unit) where downstream equipment is sensitive to finer particles, or the 40 um standard for general protection. The square gauge is fitted here in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G and NPT as order options, and the mounting bracket is included. Because flow is published as curves rather than a single rating, 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 GFR600 series as curves, not as a single rated figure, so we do not quote one here. Tell us your line pressure, set pressure and air demand and we will confirm the flow figures from the datasheet for your operating point before you order.
The automatic drain on this unit ejects collected condensate without anyone opening it, which suits installations that are not visited daily. The alternatives are a manual drain, where an operator drains the bowl, and the differential-pressure default, which drains on a pressure differential; all three are orderable choices on the GFR600.
