The AirTAC GFR30010JC2W AirTAC Filter Regulator 3/8 in PT, 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 PT3/8" 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 GFR30010JC2W is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 300 unit with a PT3/8 port, a 5 um filter element (the W grade, finer than the 40 um standard), a differential-pressure drain, a round pressure gauge reading in psi, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of PT, G (BSPP) or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and a range of gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Filtering and regulating the shop-air feed to a CNC machining centre's tool-changer and clamping circuit, with the 5 um element protecting fine control valves from particulate.
Conditioning air for the pick-and-place cylinders on a carton or food packaging line, holding a steady regulated pressure so sealing and forming motions stay repeatable.
Serving as the point-of-use filter regulator on an assembly-plant manifold feeding air screwdrivers and press cylinders, with the psi gauge giving operators a local pressure check.
Choose the size and port against the air demand of your circuit: this unit is size 300 with a PT3/8 port, and larger sizes carry larger ports and more flow. The 5 um element (code W) suits applications needing finer filtration than the 40 um standard, and the differential-pressure drain is the catalogue default, with automatic and manual drains available as options. The round gauge fitted here reads in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. PT thread is standard on this model, with G (BSPP) and NPT available to order, and brackets can be specified where panel or wall mounting is needed. Flow for this family 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.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and datasheet figures for this size 300, PT3/8 unit on request.
The W code selects the 5 um filter grade instead of the 40 um standard, giving finer removal of particulate ahead of sensitive valves and cylinders, while the differential-pressure drain bleeds off collected water automatically. Drain type, gauge scale and thread are all catalogue options on the GFR300 if you need a different combination.
