The AirTAC GFR600C25MC1WTK AirTAC Filter Regulator 1 in NPT 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 GFR600C25MC1WTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration is the large size 600 unit with a 1 in NPT port, the fine 5 um filter element (code W), a manual drain for the bowl, a round pressure gauge reading in MPa, and a built-in check valve (code K) that holds downstream pressure when the upstream supply is dropped. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT as standard with G (BSPP) and NPT as order options, and with a choice of drain type, filter grade, gauge style and scale, and check valve. Flow is published as curves rather than a single rated figure, so ask us and we will 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 supply drop feeding a paint booth's air-operated guns and agitators, the unit strips water and fine particulate and holds the line at the pressure the booth was set up for, while the check valve keeps the setting stable if upstream supply is interrupted.
On a palletizer or case erector, the large 1 in port feeds the main air header for clamp and pusher cylinders; the regulator keeps actuator pressure repeatable shift after shift and the 5 um element protects the directional valves downstream.
In a machining cell, hydraulic/pneumatic workholding clamps need steady pressure to hold parts safely; this filter regulator conditions the supply to the clamp circuit, and the round MPa gauge gives the operator a clear reading at the setpoint.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when the line serves several large consumers at once; if your demand is modest, a 200/300/400 unit on a smaller port is usually the more economical choice. This unit carries the 5 um element (W) instead of the 40 um standard - choose 5 um where downstream valves and instruments want finer filtration, and note that a finer element loads faster, which matters when picking the drain. The manual drain here means an operator opens the drain periodically; if the unit sits where nobody walks by, consider the automatic or differential-pressure drain versions instead. The round gauge reads in MPa; psi and bar scales are available, as is the embedded square gauge style. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) can be ordered. A bracket is included for panel or wall mounting. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated number, so we do not quote a rated flow figure. Tell us your application - port size, downstream demand and working pressure - and we will confirm the datasheet and flow-curve figures for the GFR600C25MC1WTK on request before you order.
W is the fine filtration option: a 5 um element instead of the 40 um standard grade. Choose 5 um when the air feeds sensitive valves, instruments or process equipment; the 40 um grade is the usual choice for general plant air. This unit also has a manual drain, so with the finer element it is worth checking the bowl on a regular maintenance schedule.
