The AirTAC GFR300C10LF2WT 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 AirTAC GFR300C10LF2WT is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with NPT3/8 ports, the low-pressure regulator type, 5 um filtration (the finer of the two catalogue grades), a differential-pressure drain on the metal bowl, and an embedded square gauge scaled in psi. A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is offered with manual or automatic drains, 40 um or 5 um filtration, and gauge scale choices in MPa, psi or bar. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

On a CNC fixture circuit that clamps and unclamps workholding cylinders, this unit filters the shop air to 5 um and holds a steady reduced pressure so clamping force stays consistent from cycle to cycle.
On a bottling or packaging line, the 5 um element protects filler and capper valve pilots from water and particulate carryover, while the low-pressure regulator sets a gentle, stable supply to the machine's air actuators.
Feeding diverter gates and pusher cylinders on a warehouse sortation conveyor, this unit keeps moisture and debris out of the directional valves and lets the crew read supply pressure at a glance on the psi gauge.
Start with the port step: this unit is NPT3/8 in the size-300 body, so check that your line's fittings and expected air demand sit comfortably within a 3/8 inch circuit - step up to size 400 or 600 if your flow needs are larger. The 5 um element (code W) suits circuits with sensitive valves or instruments; choose the standard 40 um grade where only coarser protection is needed. The differential-pressure drain bleeds the bowl automatically as pressure drops across the element, with no daily manual draining. The square gauge reads in psi; MPa or bar scales are available. PT is the standard thread, with G (BSPP) and NPT as order options, and a bracket is included with this unit. Because GFR flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet 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 GFR flow as performance curves rather than a single rated number, so we do not quote a figure here. Send us your line pressure, downstream demand and port size, and we will confirm the flow and full datasheet figures for this exact model on request.
The W in the code selects the 5 um filtration grade - the finer option versus the standard 40 um element - which suits circuits with sensitive valves or instruments. The drain is differential-pressure type: it discharges collected condensate automatically as flow conditions change, so the bowl does not need routine manual draining.
