The AirTAC GFR30010LC2WT AirTAC Filter Regulator 3/8 in NPT, 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 GFR30010LC2WT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates the pressure delivered downstream. This unit is built on the GFR300 size with a 3/8 in NPT port, a 5 um filter element (the finer of the two published grades), and a differential-pressure drain, the default drain type for this family. The regulator is the low-pressure type, and a round gauge reading in psi is fitted so the setpoint can be watched directly. The polycarbonate bowl suits the 300 size, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans four sizes (200, 300, 400 and 600) with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, gauge and thread options, and a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature for this family is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Filtering and regulating the air feeding cylinder-driven sealing and filling stations on a packaging line, where the 5 um element helps keep water and debris out of directional valves.
Conditioning supply air for a robotic pick-and-place cell, holding a steady low setpoint to the gripper circuit while the round psi gauge lets technicians verify settings at a glance.
Delivering clean, regulated air to spray guns in a paint booth, where a lubricator is deliberately left out of the circuit and the 5 um element helps protect finish quality.
Size and port step up with flow: the GFR300 carries a 3/8 in port in this NPT-thread version (G and PT threads are order options). Choose the drain to match service: differential-pressure (this unit, the default), automatic (code A) for unattended condensate removal, or manual (code M) where you drain by hand. The element here is 5 um (code W); the standard 40 um grade suits applications that do not need finer filtration. The fitted round gauge reads in psi (scale 2); embedded square gauges and MPa or bar scales are alternatives. The regulator is the low-pressure type - its exact adjustment range is not published, so confirm it against your setpoint before ordering. Bracket is included. Because rated flow is published only as curves, not a single figure, send us your flow requirement and we will confirm sizing from the datasheet.
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 GFR300 as curves rather than a single rated figure, so we do not quote a number here. Send us your flow requirement and we will confirm sizing from the datasheet before you order.
The L in the code marks the low-pressure regulator type, used where the working setpoint sits below what the standard version is set up for. AirTAC does not publish the exact adjustment range for the low-pressure version, so tell us your setpoint and we will confirm suitability from the datasheet.
