The AirTAC GFR60025AC1WTK 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 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 series combines water and particulate filtration with pressure regulation in a single body. This GFR60025AC1WTK is the size 600 unit with a 1 in NPT port, automatic drain, a 5 um filter element (code W; 40 um is the standard grade), a round pressure gauge with MPa scale, and a reverse/check valve fitted. The bowl on size 600 is aluminium alloy, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series filter regulator range runs from size 200 to 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and thread options, and a low-pressure type. The standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi). Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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, the unit strips water and particles from the header supply, holds a steady regulated pressure to the distribution lines, and the automatic drain clears collected condensate without a daily walk-round.
On a bottling line, the filter-regulator supplies clean, regulated air to the cylinder banks that index, clamp and divert containers, with the check valve holding the set pressure if the upstream supply dips.
Feeding the pneumatic clamps on CNC machining fixtures, the 5 um element protects the clamp valves from particulate and water, while the regulator keeps clamping pressure consistent from part to part.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs; this size 600 unit takes a 1 in port for the largest frame in the range. Choose the drain to match maintenance: automatic (this unit) dumps condensate without attention, manual needs a periodic press, and the differential-pressure default bleeds only while flow runs. Pick 5 um (this unit) where downstream valves and instruments need finer air, or 40 um for general protection. Gauge scale is selectable as MPa, psi or bar, and the thread can be ordered as PT (standard), G (BSPP) or NPT (this unit). A bracket is included; on request the code can specify no bracket. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet curves before you order.
The automatic drain (code A on this model) ejects collected condensate on its own, which suits unattended or high-humidity installations. Manual drain relies on someone pressing the button periodically, and the differential-pressure default bleeds only while air flows. All three are orderable choices on the GFR600; the regulation range for automatic and differential-pressure drains is 0.15-0.9 MPa (20-130 psi).
