The AirTAC GFR300C15JC2W AirTAC Filter Regulator PT1/2 5 um 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 GFR300C15JC2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, with a 1/2 in PT port. It removes water and particulate from compressed air at the fine 5 um grade (code W) and regulates downstream pressure over 0.15-0.9 MPa (20-130 psi). The differential-pressure drain bleeds accumulated condensate automatically whenever the pressure differential across the element is sufficient, so no manual draining routine is needed. An external round gauge with a psi scale is fitted on this configuration, and no mounting bracket is included.
This is a genuine AirTAC part in the 300 size of the G-series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the 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.

Point-of-use conditioning ahead of a CNC machine's pneumatic valves and actuators: the 5 um element protects spool valves from particulate and the regulator holds a steady set pressure for consistent clamping and tool-change cycles.
Feeding the cylinders and grippers on a packaging or palletising conveyor, where the 1/2 in port matches the main drop leg and the regulator keeps actuator speed repeatable as factory air pressure fluctuates.
A wall- or frame-mounted conditioning point at an assembly bench or work cell, giving operators clean, dry air at a locked set pressure for air tools and small pneumatic fixtures, with condensate handled by the differential-pressure drain.
Choose the size and port step against the air demand of the line: this unit is size 300 with a 1/2 in PT port, one step up in flow capacity from the 1/4 in and 3/8 in sizes and below the 3/4 in and 1 in sizes. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard; if coarser, economical filtration is acceptable, the 40 um version of the same body is the alternative. Drain type is a real choice: differential-pressure (this unit) drains on pressure differential, automatic drains on a timer-free float principle, and manual requires periodic draining. Gauge scale (MPa, psi or bar - psi fitted here) and thread (PT standard, G or NPT to order) are also selectable, and a bracket can be ordered if this no-bracket version does not suit the mounting.
Flow for the GFR300 is published as curves, not a single rated number, 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 flow for the GFR300 as curves rather than a single rated figure, so we do not quote a rated number. Tell us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
The blank drain position in the code means the differential-pressure drain: condensate is discharged automatically when the pressure differential across the filter element is sufficient, with no operator action. If your duty cycle leaves long low-flow periods, the same body is available with an automatic (A) or manual (M) drain instead.
