The AirTAC GFR Filter Regulator GFR300C15ANW 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 AirTAC GFR series is a filter regulator: one body that removes water and particulate in a drain bowl and then regulates downstream pressure. This GFR300C15ANW is the 300 size with PT1/2 (1/2") ports, an automatic drain that clears condensate unaided, and the optional fine 5 um filter element (W) in place of the 40 um standard. No gauge is fitted (N); a mounting bracket is included.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600, with PT standard threading plus G and NPT options and a choice of drain types and filter grades, and we confirm flow and datasheet 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.

Conditioning the air feeding lab pneumatic actuators and sample-handling devices, where the 5 um element keeps fine debris out of sensitive components and the regulator holds a stable set pressure.
At workbenches where air tools and small cylinders are used, it dries and cleans the supply with the fine element and lets technicians dial in the pressure each task needs.
Supplying the vacuum generators and air cylinders of a pick-and-place module, it protects the fine components from moisture and particles and maintains the steady pressure the placement cycle expects.
Use this code when your 1/2" line needs both regulation and finer-than-standard filtration: the 5 um element (W) is the choice for circuits feeding pneumatic valves, precision cylinders or instruments that the 40 um standard element leaves exposed. The automatic drain keeps the bowl clear without operator attention, and the adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi) at up to 1.0 MPa (145 psi) inlet, working from -5 to 70 C. Order the non-W version if 40 um is sufficient, and a gauge variant if you need local pressure readout. Flow is published as curves, not a single rating, 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.
There is no single rated flow to design around: AirTAC publishes G-series flow as curves. Send us your line size and air demand and we will confirm from the datasheet on request that the 300 size with PT1/2 ports covers your application.
The standard 40 um element suits general plant air for cylinders and actuators. Choose the 5 um (W) version, like this GFR300C15ANW, when the downstream equipment - precision valves, instruments, air bearings or fine nozzles - needs finer protection from particles. Everything else in the decode stays the same: PT1/2 ports, automatic drain, no gauge, PT thread.
