The AirTAC GFR300C10JC2WT AirTAC Filter Regulator NPT3/8 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 GFR300C10JC2WT is an AirTAC GFR300 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration is built with a 3/8 in NPT port, a 5 um filter element for finer air cleaning than the standard 40 um grade, and a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element rises. Output pressure is set with the standard regulator over 0.15-0.9 MPa (20-130 psi), and the fitted external round gauge reads in psi so the setting can be checked at a glance. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600, with a choice of port and thread (PT standard; G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, low-pressure regulator type, reverse/check valve, and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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 for a machining centre's pneumatic circuits: the 5 um element protects solenoid valves and air bearings from fine particles while the regulator holds a steady set pressure for clamping and tool-change actuators.
Clean, regulated air for a lab automation or analytical instrument skid, where the finer 5 um grade and a visible psi gauge keep sample-handling cylinders and pick-and-place actuators supplied with consistent, filtered air.
Filtering and regulating the air feeding diverters, pushers and sealing jaws on a packaging conveyor, with the differential-pressure drain limiting condensate carry-over into the valves along the line.
Size 300 with a 3/8 in NPT port sits in the middle of the GFR range; step up to 400/600 or down to 200 depending on the pipe size and flow your line needs. The 5 um element (code W) is the right choice when downstream valves, cylinders or instruments are sensitive to finer particles than the standard 40 um grade removes. The differential-pressure drain needs no daily attention, but if the unit cannot be mounted vertically or the air is very wet, consider the automatic or manual drain variants instead. The round psi gauge matches US practice; square embedded gauges and MPa or bar scales are also available. NPT is an order option on this family - PT is the catalogue standard thread - and the no-bracket (J) build suits direct panel or manifold mounting where a bracket is not wanted.
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 series as curves, not as a single rated figure, so we do not state a flow number. Tell us your application and required flow and we will confirm the datasheet and check the sizing for you on request.
The W code in the model number selects the optional 5 um filter grade, which removes finer particles than the 40 um standard element. Choose it when downstream valves, instruments or processes need cleaner air; the standard 40 um grade is available on other GFR300 variants.
