The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, 5 um, Auto Drain 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 PT1" 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 GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit carries a 1 in PT port, a 5 um filter element (the fine grade, in place of the standard 40 um), an automatic drain that ejects collected condensate without manual attention, and an aluminium alloy bowl. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the code includes a round external gauge reading in psi plus a reverse (check) valve. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain, filter-grade, gauge, thread (PT, G, NPT) and bracket options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.

Dropping a 1 in filter regulator into the main drop feeding a packaging hall: it strips water and fine dirt from the header air and holds a steady regulated pressure to the machines below, with the automatic drain handling condensate on its own.
Feeding the air cylinders and grippers on a bottling conveyor: the 5 um element keeps fine particulate out of the valve stack, the regulator holds consistent cylinder speed, and the check valve protects the setting if upstream supply dips.
Mounted on the bracket inside a control cabinet or pneumatic panel of an OEM machine: one 1 in connection prepares and regulates the whole panel supply, with the round psi gauge giving the operator a direct pressure readout at the door.
Step up or down through the GFR sizes (200/300/400/600) against the port and flow your line needs; this is the 600 size with a 1 in PT port, the largest in the range. Choose the drain to suit access: automatic (fitted here) for unattended condensate removal, manual where you prefer operator-controlled blows, or the differential-pressure default. Pick 40 um for general protection or 5 um (this unit) where downstream valves and instruments need finer air. Gauge choices are the embedded square type or an external round gauge in MPa, psi or bar scales (this code: round, psi). Thread is PT as standard with G (BSPP) and NPT as order options, and a reverse/check valve can be fitted as here. Flow is published as curves, not a single rating, so have us confirm sizing against your application before ordering.
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, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The automatic drain (code A) ejects collected condensate by itself, so the aluminium bowl does not need periodic manual blowing - useful for units mounted high or in unattended areas. The W code fits the 5 um element instead of the standard 40 um, giving finer filtration for downstream valves and instruments; both grades are available across the GFR range.
