The AirTAC GFR300C10LC2W AirTAC Filter Regulator 3/8 in, 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 GFR300C10LC2W is a size-300 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, a low-pressure regulator type, and a round pressure gauge reading in psi. The port is PT3/8 (3/8 in) with PT thread as the standard, a mounting bracket is included, and maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauge styles and scales, and G or NPT thread as order options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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.

Feeds clean, regulated air to the clamp cylinders on a CNC machining cell, where the 5 um element protects seal surfaces and the low-pressure regulator holds a gentle, consistent clamp force.
Conditions the air feeding diverters, pushers and bag-forming actuators on a packaging conveyor, with the differential-pressure drain clearing condensate through continuous shifts without daily manual blowing down.
Prepares the air feeding grippers and small actuators on laboratory automation equipment, where the 5 um grade and a psi-reading gauge suit instruments specified in imperial units.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the flow your line needs; this unit is the size-300 step at PT3/8. Choose the drain to suit access: differential-pressure (this unit, automatic in service), fully automatic (code A), or manual (code M). Filter grade is 40 um standard or 5 um with code W, which is what this unit carries. Gauge choices are round or square with MPa, psi or bar scales; this configuration is a round gauge reading psi. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included.
Because flow is published as curves and not a single rating, 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 there is no one rated flow number we can honestly quote. Tell us your line conditions and we will confirm the flow figures from the datasheet for this exact model on request before you order.
The W in the code GFR300C10LC2W selects the 5 um filter grade instead of the 40 um standard. The finer element suits actuators, valves and instruments that are sensitive to finer particulate. If you prefer the standard grade, the same size-300 body is available without the W suffix.
