The AirTAC GFR600C25AJF3WTK AirTAC 1 in NPT Filter Regulator 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 GFR600 series combines water-and-particulate filtration with pressure regulation in a single body, and this configuration, the GFR600C25AJF3WTK, is built for a 1 in NPT connection on compressed-air lines. It filters to 5 um (the finer of the two catalogue grades), drains condensate automatically, and regulates downstream pressure within the 0.15-0.9 MPa (20-130 psi) range appropriate to the automatic-drain version. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 600-size bowl is aluminium alloy, an embedded square gauge graduated in bar is fitted, a reverse/check valve is included, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 40 um standard element, alternative gauge scales (MPa, psi or bar) and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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.

At the drop feeding spray booths and air-assisted applicators, this unit removes water and fine particulate down to 5 um and holds a steady regulated pressure, with the automatic drain clearing collected condensate between shifts.
On the main air drop serving the case erectors, sealers and stop-gate cylinders along a packaging conveyor, the 1 in NPT connection conditions the whole line feed while the regulator holds a consistent setting for repeatable actuator stroke.
Mounted at the machine's air-inlet panel, this filter regulator conditions the supply feeding tool-change clamps and chip-clearing jets, with the reverse/check valve holding the downstream circuit if the shop supply is interrupted.
Start with the port and size step: the GFR600 in this configuration carries a 1 in NPT connection, the largest in the range, so step down to a 300 or 400 size if your line and expected flow are smaller. Choose the drain to match maintenance access: automatic drain (as here) suits unattended or hard-to-reach installations, manual drain suits attended plants, and differential-pressure drain is the catalogue default. Choose the filter grade: 40 um is standard for general protection, while the 5 um element fitted here is the finer option for downstream equipment that needs cleaner air. Gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options) are decodable choices, and a mounting bracket can be ordered where this no-bracket version does not suit the mounting. 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 flow for the GFR600 series as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
The W in the code specifies the finer 5 um filter grade, and the A specifies the automatic drain. The 5 um element suits downstream equipment that needs cleaner air than the 40 um standard provides, and the automatic drain expels collected condensate without manual attention - useful where the unit is mounted in a spot that is awkward to reach. A 40 um element and manual or differential-pressure drain are available as alternative configurations.
