The AirTAC GFR30010LC2WTK AirTAC Filter Regulator NPT 3/8 in, 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 PT3/8" 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 GFR30010LC2WTK is an AirTAC GFR filter regulator: a 5 um filter and a pressure regulator combined in one body, so a single unit removes water and particulate from the air line and holds a set downstream pressure. This configuration is the 300 size with a 3/8 in NPT port, the 5 um element (code W), a differential-pressure drain, the low-pressure regulator type, an external round gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The bowl is polycarbonate (PC); maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and in standard or low-pressure regulator types, with a choice of drain (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge type and scale, thread (PT standard; G and NPT to order) 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.

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.

| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Filtered, regulated air to gripper circuits on assembly robots: the 5 um element protects the small directional valves from particulate and moisture, and the low-pressure regulator holds a steady set pressure for gentle part handling.
Air preparation for quarter-turn actuator panels on process lines: the filter keeps pipe scale and condensate out of the positioner, the regulator sets the actuator pressure, and the fitted check valve holds the setting if upstream pressure dips.
Supply for diverter and pusher cylinders on a packaging conveyor: one body does the filtering and the regulation, the round psi gauge lets the line technician read the setting at a glance, and the included bracket simplifies panel mounting.
The real choices within the GFR300 series are the port size against the flow your line needs (this unit steps to 3/8 in NPT; move to the 400 or 600 size for larger ports), the drain type (differential-pressure as fitted here, or automatic or manual), the filter grade (40 um standard, 5 um where finer protection matters, as on this unit), the gauge (embedded square or external round, scaled in MPa, psi or bar - this unit carries a round psi gauge), the thread (PT is the standard; G and NPT are order options, NPT on this unit), and the bracket. The low-pressure type (code L) is the regulator variant for circuits that sit below the standard adjust range; its exact range is not published, so confirm it with us. Flow is published as curves, not a single rating - send us your flow and pressure requirements 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 one number. Tell us your flow and pressure requirements and we will confirm the sizing from the datasheet on request before you order.
The W code selects the 5 um element instead of the 40 um standard, for finer protection of downstream components. The drain is the differential-pressure type (the default), which discharges collected condensate as the pressure differential across the element rises; automatic and manual drains are available in the same family if your duty needs them.
