The AirTAC GFR20008LC3WT AirTAC Low-Pressure Filter Regulator NPT1/4 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 PT1/4" 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 GFR20008LC3WT is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 200-size unit is supplied with a 1/4 in NPT port, the 5 um filter element (the finer of the two published grades), a differential-pressure drain on the PC bowl, a round pressure gauge reading in bar, and the low-pressure regulator type. 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 spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm flow figures and the full datasheet 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. 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| 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.

Sits ahead of the clamping cylinders on a CNC fixture line, cleaning the shop air and holding a steady clamp pressure set in the low-pressure range so parts stay gripped consistently through the cycle.
Conditions the supply feeding sensitive pneumatic lab instruments and sample-handling actuators, where the 5 um element keeps particulate and water carryover away from fine orifices and valves.
Placed at the drop feeding small cylinders and diverters on a packaging conveyor, combining filtration and low-pressure regulation in one body to keep the machine's air clean and its setpoint stable.
Size and port: the 200 frame with a 1/4 in NPT port is the entry step of the GFR range; step up through 300, 400 and 600 when the application calls for larger ports and more flow. Match the port to your piping and ask us to confirm the flow curve against your air demand before ordering. Filtration: this code carries the 5 um (W) element; if your downstream equipment tolerates coarser air, the 40 um standard element is available on other GFR codes. Drain: the differential-pressure drain is the default; automatic-drain codes suit unattended duty and manual-drain codes suit scheduled draining. Regulator type: this is the low-pressure (L) type; the exact regulating range for this variant is not published in the material we hold, so ask us to confirm it against your set pressure. Gauge: the fitted round gauge reads in bar; square gauges and MPa or psi scales are orderable. Thread: PT is the catalogue standard with G (BSPP) and NPT as order options - this code is the NPT variant. Mounting bracket included.
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 we do not quote a number here. Tell us your line pressure, set pressure and air demand, and we will confirm the flow curve for the 200 size against your application on request.
L marks the low-pressure regulator type. The exact regulating range for this variant is not published in our current material, so if your set pressure is specific, ask us to confirm suitability before ordering. Everything else decodes normally: 200 size, 1/4 in NPT port, 5 um element, differential-pressure drain, round bar gauge, bracket included.
