The AirTAC GFR60025ALC1WTK AirTAC Filter Regulator 1 in NPT 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 GFR60025ALC1WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is built around a 1 in NPT port and carries the fine-filtration option (W code, 5 um element) instead of the standard 40 um grade. The A code gives an automatic drain, so collected condensate is expelled without manual attention, and the L code specifies the low-pressure regulator type, suited to circuits that run below the standard setting band. The C1 code adds an external round gauge scaled in MPa, the K code fits a reverse (check) valve, and the aluminium alloy bowl reflects the 600 size. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeding a big stamping or forming press that runs its clamping and counterbalance cylinders at a reduced line pressure: the GFR body filters scale and condensate from the main drop and holds the reduced setting, while the automatic drain keeps water out of the valve stack below.
Conditioning the air feeding a multi-station cartoning or case-packing manifold: the 5 um element protects directional valves and actuators from fine particulate, the check valve holds the downstream circuit against backflow, and the MPa gauge gives operators a clear setpoint reference.
Serving a process or conveying circuit that operates below the standard regulator band: the low-pressure (L) type lets the line run at a gentle reduced setting, the automatic drain handles condensate at an unattended drop, and the 1 in NPT port matches the main header.
Start with the port step: size 600 with a 1 in port is the largest GFR frame, so match it to the line volume your circuit actually carries rather than upsizing on guesswork. Choose the drain to suit access: automatic (this unit) for points that are hard to reach or run unattended, manual where an operator checks the bowl routinely, or the differential-pressure default. Choose the 5 um element (W) when downstream equipment needs finer filtration than the standard 40 um grade. Pick the gauge scale you want to read - MPa, psi or bar - and the thread to match your piping: PT is the standard, with G (BSPP) and NPT as orderable options. A bracket is included on this configuration; the J code omits it on other variants.
One honest routing note: AirTAC publishes flow for this family as curves, not as a single rated number, and the exact regulation band of the low-pressure (L) type is not stated on the summary sheet. Send us your line pressure, required downstream setting and flow demand and we will confirm the sizing against the datasheet before you order.
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 GFR family as curves, not as a single rated figure, so we do not quote a rated number for this unit. Tell us your line pressure, the downstream setting you need and the flow demand of the circuit, and we will confirm the sizing against the datasheet before you order.
Both are decoded from the model code. The A position selects the automatic drain, which expels collected condensate on its own instead of waiting for a manual bleed - useful at drops that are not checked daily. The W position selects the 5 um filter element in place of the standard 40 um grade, for circuits where downstream valves and cylinders need finer protection.
