The AirTAC AirTAC GFR600C25AF2W Filter Regulator PT1 in, 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 GFR600C25AF2W is a 600-size filter regulator that removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a 1 in PT port, a 5 um filter element (the finer of the two published grades), an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in psi. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports 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 in MPa, psi or bar scales, and PT, G or NPT threads. Published flow data appears as curves rather than a single rating, so ask us to 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.

Installed at the 1 in supply point feeding a paint shop, it strips water and 5 um particulate from the plant air and holds a stable regulated pressure so spray booths receive clean, consistent air at the header.
Mounted ahead of the valve manifold bank on a bottling conveyor, it delivers filtered, regulated air to the clamp and pusher cylinders while the automatic drain keeps condensate out of the circuit during long production runs.
Fitted on the 1 in distribution line serving a CNC machining cell, it conditions the shop air and regulates pressure downstream of the compressor receiver, protecting pneumatic tool circuits and machine clamping from pressure drift.
Start with the port step: this unit is the 600 size with a 1 in PT connection, the largest in the GFR range, so match it to a main air line where the pipe run and expected demand sit at the top of the family's capacity. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. Then set the remaining decodable options: the automatic drain on this model suits unattended installations, while manual and differential-pressure drains are available if you prefer scheduled or load-linked purging; the 5 um element here is the finer option versus the 40 um standard; the square gauge reads psi, with MPa and bar scales and an external round gauge as alternatives; and PT is the standard thread with G and NPT available to order. A mounting bracket is included with this configuration.
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 rather than a single rated figure, so no one number would be honest. Tell us your line pressure, port size and demand and we will confirm the flow and sizing data from the datasheet on request before you order.
The A in the code sets the automatic drain, which expels collected condensate from the aluminium alloy bowl on its own - useful where the unit is mounted in a hard-to-reach spot or runs unattended. The family also offers a manual drain for supervised installations and a differential-pressure drain (the default) that purges in response to the pressure drop across the element.
