The AirTAC GFR300C15JC2WGK AirTAC Filter Regulator G1/2, 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 AirTAC GFR300C15JC2WGK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around a G1/2 (BSPP) port on the 300 size, with a 5 um filter element for finer contamination control than the standard 40 um grade and a differential-pressure drain, the default drain type for this family. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit is fitted with a round external gauge reading in psi plus a reverse/check valve. It comes without a mounting bracket, and the size-300 polycarbonate bowl gives a clear view of condensate level.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and can be ordered with manual or automatic drains, a 40 um or 5 um element, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

On a machining line, each CNC cell needs air that is both clean and held at a set pressure for tool clamping and actuated doors. A GFR300 filter regulator at the cell drop conditions the supply in one body, and the 5 um element suits the sensitive valves on these machines.
Carton sealers, case packers and wrap stations on a packaging line run cylinders that need steady pressure to seal and fold consistently. This G1/2 filter regulator mounted at the line take-off cleans the air and holds the set point, with the round psi gauge giving operators a local reading.
Pneumatic diverters and pusher gates on a distribution conveyor fire hundreds of times a shift and are sensitive to dirty air and pressure drift. A GFR300 filter regulator feeding the gate manifold keeps contaminant and pressure variation out of the control valves, and the check valve holds the set circuit against backflow.
Start with size and port: the 300 size with its G1/2 port serves larger air drops than the 200 size, while the 400 and 600 sizes step up for higher demand - match the size step to your flow requirement and we will check it against the published curves. Element choice is 5 um here versus the standard 40 um grade: choose 5 um when downstream valves and cylinders need finer protection. The differential-pressure drain is the default; automatic (A) and manual (M) drains are orderable alternatives. The round psi gauge can be specified instead as an embedded square gauge, and MPa or bar scales are available. G thread can be ordered as PT or NPT, and a mounting bracket can be added where this no-bracket configuration needs one. Because flow is published as curves rather than a single rating, send us your application conditions and we will confirm sizing before you order.
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 in the catalogue, not as a single rated figure, so we do not quote a number here. Send us your application flow and working pressure and we will confirm from the datasheet whether the 300 size with its G1/2 port is the right step for your line.
The W selects the 5 um filter element instead of the standard 40 um grade. Choose 5 um where finer particulate and water carryover control protects sensitive valves and actuators; the standard 40 um grade is available on other GFR300 variants if your application does not need the finer filtration.
