The AirTAC GFR300C10JF1WT 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 GFR300C10JF1WT is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is threaded NPT3/8, carries the 5 um filter element (code W) in place of the 40 um standard, drains condensate automatically by differential pressure, and is fitted with the embedded square gauge scaled in MPa. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range, maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), the 300-size bowl is PC (polycarbonate), and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the full datasheet 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.

Clean, dry, pressure-stable air for the tool-changer and clamping circuits of a CNC machining cell, with the 5 um element protecting fine pilot valves from particulate carryover.
A single point of filtration and regulation feeding the stopper, pusher and lift cylinders on a food or carton packaging conveyor, keeping setpoint steady as stations cycle.
Conditioning the air supply to a paint-booth spray-gun circuit, where the 5 um grade helps keep the atomizing air free of water and debris that would mar the finish.
Size and port set the capacity: this 300-size unit takes a 3/8 in NPT connection; step up to size 400 or 600 when demand outgrows it, or down to 200 for compact circuits. The 5 um element (code W) suits finer air preparation; the 40 um standard element remains available if coarse protection is enough. Drain choice is differential-pressure (as here), automatic or manual. The embedded square gauge is scaled in MPa here, with psi or bar scales and an external round gauge as alternatives. PT is the standard thread; G and NPT are catalogue options to order. A bracket can be added where this no-bracket code omits it. 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.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a flow number here. Send us your line pressure, set pressure and air demand, and we will confirm sizing from the datasheet on request before you order.
Code W fits a 5 um element for finer particulate removal, which suits instruments, spray applications and sensitive pilot circuits. The 40 um standard element is adequate for general cylinder and valve supply. Both grades are available across the GFR range in the same bodies.
