The AirTAC GFR30015LC2WK AirTAC Filter Regulator PT1/2, 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 PT1/2" 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 GFR30015LC2WK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, with a 1/2 inch PT port. The W code specifies the fine 5 um filter element for cleaner downstream air, the L code specifies the low-pressure regulator type, and the C2 code adds an external round gauge with a psi scale. A reverse/check valve is fitted, the bowl drains by differential pressure, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain, filter-grade, gauge, thread and valve options to match. Flow figures are published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 and regulates the air to a pneumatic clamping manifold on a machining centre, with the 5 um element protecting clamp cylinders and the check valve holding clamp pressure if the main supply dips.
Conditions the supply to spray guns and air-assisted applicators, where the fine 5 um grade keeps water and particulate out of the finish and the low-pressure regulator type matches lower working pressures.
Sits at the drop of a packaging or cartoning machine to filter and regulate air for diverters, sealers and small actuators, with the psi gauge giving operators a local setpoint check.
Size 300 with a PT1/2 port sits mid-range in the GFR family: step up to size 400/600 or down to 200 depending on the port and flow your line needs. The 5 um element (code W) suits air that feeds sensitive valves, cylinders or instruments; the standard 40 um element is enough for general circuit protection. The low-pressure regulator type (code L) is chosen where the working circuit sits below the standard adjust band - its exact range is not published, so confirm it with us. The round psi gauge (C2) gives a local reading in imperial units, the fitted check valve holds downstream pressure if upstream supply drops, and PT is the standard thread with G (BSPP) and NPT available as order options. Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The L code makes this a low-pressure regulator type, chosen for circuits that work below the standard adjust band; the exact range is not published, so confirm it with us. The W code fits the 5 um element instead of the standard 40 um grade, for cleaner air feeding sensitive valves, cylinders or instruments.
