The AirTAC GFR600C25AF2G AirTAC Filter Regulator G1 Auto Drain 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 GFR600C25AF2G is a filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 configuration carries a G1 (1 in) port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and a fitted square gauge reading in psi. The bowl on this size is aluminium alloy, max working pressure is 1.0 MPa (145 psi), and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, automatic, manual or differential-pressure drains, 40 um or 5 um (code W) filtration, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm datasheet 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.

Point-of-use filtered, regulated air for pneumatic nutrunners, clamps and fixtures along a vehicle assembly line, with automatic condensate draining between shifts.
Supplying clean, regulated air to cylinder-driven pushers and diverters on a bottling or carton conveyor, where the 1 in port feeds a high-demand header.
Conditioning shop air ahead of tool-change clamps and air bearings on a machining centre, with the psi gauge giving operators a familiar local pressure readout.
Size and port set the capacity step: this unit is size 600, the largest in the range, with a 1 in G-thread port. Drain type is a real choice within the family: automatic (this unit) suits unattended duty, manual suits lines with routine checks, and differential-pressure is the catalogue default. Filter grade is 40 um standard; specify W for 5 um where finer particulate control matters. Gauge scale (MPa, psi or bar), thread (PT standard; G or NPT as order options) and bracket are also decodable choices. Flow is published as curves, not a single rating, so 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 GFR flow as performance curves rather than a single rated figure, so no one number is quoted here. Tell us your line pressure, downstream demand and allowed pressure drop, and we will confirm the sizing from the datasheet before you order.
The automatic drain expels collected condensate on its own, which suits unattended or hard-to-reach installations. The GFR family also offers manual drains for attended lines and a differential-pressure drain as the catalogue default, so you can match the drain to your maintenance routine.
