The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT 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 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 GFR600-25T is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is specified with a 1 in NPT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a fitted square gauge scaled in psi so the regulated outlet pressure can be read at a glance. The standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and PT, G or NPT threads. The 600 size uses an aluminium alloy bowl suited to larger installations. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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 a 1 in drop from a factory compressed-air ring main, it cleans the supply of water and pipe scale and holds a steady regulated pressure for the whole downstream cell.
Mounted at the inlet of a control panel or valve manifold, it conditions the air feeding directional valves and actuators, with the psi-scaled square gauge letting technicians verify the set pressure during commissioning.
Placed ahead of cylinder-driven clamping or gating stations on a packaging or assembly line, it supplies filtered, pressure-regulated air so stroke force and cycle behaviour stay consistent shift after shift.
Choose the size and port step against the air demand of the line: the GFR series steps through sizes 200, 300, 400 and 600, and this 600 unit carries the largest port in the range at 1 in NPT. Drain type is a real choice: automatic drain (as fitted here) suits unattended duty, while manual and differential-pressure drains are available in the series. Filter grade is 40 um standard or 5 um with the W code if finer filtration is needed. The gauge can be ordered with MPa, psi or bar scale, and an external round gauge is an alternative to the standard embedded square gauge. Thread options are PT (standard), G (BSPP) or NPT, and a bracket can be omitted with the J code.
Because flow for this series is published as curves rather than a single rated figure, send us your application details and we will confirm the sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, port size and air demand and we will confirm the flow from the datasheet for your application before you order.
The A in the code GFR60025AF2T specifies the automatic drain, which discharges collected condensate from the bowl without anyone having to open it - useful on lines that run unattended. The GFR series is also available with a manual drain or the differential-pressure drain; just order the corresponding code.
