The AirTAC GFR30015JC2WT AirTAC Filter Regulator NPT1/2, 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 PT1/2" 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 GFR30015JC2WT is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/2 in NPT port, a 5 um filter element (the W grade, finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and an external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits operating temperatures of -5 to 70 C (non-freezing). No mounting bracket is fitted (code J).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT as order options), bracket and reverse/check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, regulated air to the tool-change and clamping circuits of a CNC machining centre, with the 5 um element guarding against particulate carryover into precision valves.
Conditions the air feeding carton-forming and case-sealing cylinders on a packaging line, holding a stable set pressure while the differential-pressure drain handles condensate through shift-long runs.
Supplies clean, regulated air to grippers and pneumatic press fits in a robotic assembly cell, with the round psi gauge giving operators a clear local reading at the cell drop.
Size the GFR by port and expected flow: this unit is size 300 with a 1/2 in NPT port; step up to size 400 or 600 for higher flow, or down to 200 for compact lines. Choose the drain to match the installation: differential-pressure (this unit, no operator input), automatic (A) for continuous unattended drainage, or manual (M) where an operator drains on a schedule. Pick the filter grade: 40 um is the standard element, 5 um (W, fitted here) protects finer downstream components. Gauge options are the embedded square gauge or an external round gauge (fitted here), with MPa, psi or bar scales - this unit reads psi. Thread is PT as the catalogue standard, with G (BSPP) and NPT (fitted here) as order options; a bracket is optional (not fitted here). Flow is published as curves, not a single rated figure, so 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 G-series flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow data from the datasheet and check the sizing for you on request.
The W code in GFR30015JC2WT selects the optional 5 um filter grade, finer than the 40 um standard element. It suits downstream equipment that is sensitive to finer particulate. If your line only needs general water and particle removal, the 40 um standard grade (no W code) is the usual choice.
