The AirTAC GFR600-25 AirTAC Filter Regulator 1 in NPT, 5 um 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 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is fitted with a 1 in NPT port, the 5 um filter element (code W) for finer filtration than the standard 40 um, a differential-pressure drain that bleeds accumulated condensate automatically as flow passes through, and an embedded square gauge scaled in MPa. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi). Because it is the 600 size, the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket and without a reverse/check valve.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options including manual or automatic drains, 40 um or 5 um filtration, alternative gauge scales in psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet flow data 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.

Installed at the drop feeding a CNC machining centre's pneumatic clamps and tool-change cylinders, the 1 in NPT connection carries the whole cell's air while the 5 um element and regulated pressure protect the machine's valves from water and particulate carryover.
Mounted on the main air drop of a carton-forming and sealing conveyor line, this filter regulator conditions the supply feeding diverters, pushers and sealing cylinders, with the MPa gauge giving operators a visible setpoint for consistent actuator speed and force.
Used on a process skid where quarter-turn pneumatic actuators cycle large ball and butterfly valves, the unit filters the actuator air supply to 5 um and holds a stable regulated pressure so the actuators stroke consistently shift after shift.
Choose the GFR600 size when your line needs the largest port and highest flow capacity in the G-series range: this unit steps up to a 1 in connection, so match it against the flow demand of your downstream actuators and ask us to check the published flow curves before you commit. The 5 um element (code W) suits applications where finer particulate removal protects downstream valves and cylinders; the standard 40 um grade is the economy choice for general shop air. The differential-pressure drain on this unit handles condensate automatically during flow; a manual-drain version (widening the regulation range to 0.05-0.9 MPa) or an automatic drain can be ordered instead. The fitted square gauge reads in MPa; psi or bar scales and an external round gauge are options. This unit carries the NPT thread as ordered - PT is the catalogue standard and G (BSPP) is also available - and it comes without a bracket, so plan your mounting panel or bracket purchase accordingly.
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 we do not quote one number. Tell us your application's flow demand and we will confirm the datasheet flow data for this 1 in unit on request before you order.
The W in the code GFR60025JF1WT selects the optional 5 um element, which removes finer particulate than the 40 um standard grade - useful when protecting sensitive downstream valves or instruments. If your application only needs general protection, the 40 um grade is available as the default on this same size 600 filter regulator.
