The AirTAC GFR30015AC2WT AirTAC Filter Regulator NPT1/2 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 PT1/2" 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 GFR30015AC2WT is a size-300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 1/2 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, and an external round gauge reading in psi. The regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), with a maximum working (inlet) pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, and square or round gauges with MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing figures 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.

Feeds filtered, regulated air to the pneumatic tool circuits and clamping actuators on a CNC machining centre, with 5 um filtration guarding precision valves and the automatic drain handling condensate from continuous running.
Conditions the air feeding cylinder-driven carton forming, sealing and labelling stations on a packaging line, holding a stable regulated pressure so seal and clamp strokes stay consistent through each shift.
Supplies clean, regulated air to the gripper and pick-and-place circuits of a robotic assembly cell, where the 5 um element protects fine control valves and the psi gauge lets technicians verify setpoints at the panel.
Start with the size and port: 200, 300, 400 and 600 step up in port size and flow capacity, so match the size step against the air demand of the circuit rather than the pipe alone. Choose the drain to suit access: automatic (as on this unit) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drains automatically only when the pressure drop warrants it. Select the filter grade for the downstream equipment: 40 um is the standard element, 5 um (W) protects finer components such as precision valves and instruments. Pick the gauge scale (MPa, psi or bar) and square or round style to match the panel, and specify PT (standard), G or NPT thread when ordering. A mounting bracket is included on this unit.
Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 rather than a single rated figure, so no rated flow number is quoted here. We will confirm the datasheet flow curve and check the sizing against your application on request before you order.
The A code in GFR30015AC2WT specifies an automatic drain, which expels collected condensate from the PC bowl without anyone opening it. That suits units mounted in out-of-the-way positions or on equipment running unattended; manual and differential-pressure drain versions are available in the same series if you prefer.
