The AirTAC GFR600-25T AirTAC Filter Regulator NPT1, 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 GFR600-25T is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This 600-size unit is fitted with a 1 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. The 600-size bowl is aluminium alloy, and the built-in regulator adjusts from 0.15 to 0.9 MPa (20 to 130 psi). A round gauge with a bar scale is fitted so the set pressure is visible at a glance, and a reverse (check) valve is included to hold downstream pressure if the supply drops.
This is a genuine AirTAC part. The GFR family is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge style and scale options, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Installed at the 1 in drop feeding a packaging hall's distribution header, it filters water and particulate from the compressor supply and holds a steady regulated pressure to every downstream station, with the automatic drain handling condensate on a main that runs all shift.
Mounted at the air inlet of a CNC machining cell, it cleans the supply feeding spindle purge, tool-change actuators and pneumatic clamps, the 5 um element protecting fine valve spools, while the bar-scale gauge lets the setter verify set pressure during changeover.
Fitted on the supply header serving a bottling line's conveyor stops, lift gates and gripper cylinders, it regulates header pressure to a fixed setpoint and removes line moisture, with the check valve holding downstream pressure through brief supply dips.
Start with the port and size step: 600 is the largest G-series frame, and this unit carries a 1 in NPT port, so match it to your main air drop or machine inlet and to the flow your line needs. Choose the drain to suit access: automatic (as here) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the catalogue default. Pick the filter grade for the task: 40 um is standard for general protection, while the 5 um element fitted here suits finer downstream equipment. Set the gauge scale (MPa, psi or bar) to match your plant convention, and order PT, G or NPT thread to suit your piping standard. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the sizing from the datasheet flow curves before you order.
This unit's code specifies an automatic drain, which expels collected condensate on its own so the aluminium bowl does not need regular attention. The alternatives are a manual drain, emptied by hand, and the catalogue-default differential-pressure drain; all three share the same 0.15-0.9 MPa (20-130 psi) regulation range on this standard-type unit.
