The AirTAC GFR60025JC1WTK AirTAC 1 in Filter Regulator 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 GFR60025JC1WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around a 1 in NPT port for high-flow mains, a fine 5 um filter element (code W), a differential-pressure drain that bleeds condensate automatically as flow passes through, and an aluminium alloy bowl - the material used across the 600 size. A round external gauge on an MPa scale is fitted so the set pressure is visible at the wall, and a reverse/check valve (code K) holds downstream pressure if the upstream supply is lost. The J code means no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range for this drain type is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and in PT (standard), G and NPT threads, with a choice of drain types, 40 um or 5 um filtration, gauge style and scale, and optional check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Installed on a 1 in drop from the compressor room header to condition the air and set a stable working pressure for a production hall section, with the differential drain and 5 um element keeping the downstream circuit clean and dry.
Feeding the valve manifold and pneumatic cylinders of a carton-forming and sealing conveyor, where the regulator holds one set pressure for consistent stroke speed and the 5 um filtration protects directional valves from particulate.
Conditioning the air feed to spray guns and air-assisted applicators, where water and fine dirt in the supply cause finish defects and the round MPa gauge lets the operator verify the set pressure at a glance.
Step up through the GFR sizes (200, 300, 400, 600) against the flow your line needs - the 600 size with its 1 in port sits at the top of the range for larger mains. Choose the drain to suit maintenance: differential-pressure (this unit, drains with flow), automatic (A), or manual (M). Pick the filter grade: 40 um is standard for general plant air, 5 um (W, as fitted here) for finer protection of valves and instruments. Gauge style is embedded square (standard) or external round, on MPa, psi or bar scales - this unit carries a round MPa gauge. Thread is PT as standard with G and NPT as orderable options (this unit is NPT); brackets are optional (J omits it) and K adds a check valve. 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 the GFR600 series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure, set pressure and expected air demand and we will confirm the flow figures from the datasheet on request before you order.
The W code in GFR60025JC1WTK selects the optional 5 um filter grade; the GFR600 standard element is 40 um. The 5 um grade suits downstream valves, instruments and finishing equipment that need finer filtration. If your application only needs general plant-air conditioning, the 40 um version of the same size is available - tell us which grade you need and we will confirm the correct code.
