The AirTAC GFR20008LJC2WG AirTAC Filter Regulator G1/4, 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 PT1/4" 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 GFR20008LJC2WG is a size-200 filter regulator: it removes water and particulate from compressed air and controls downstream pressure in a single body. This configuration has a G1/4 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element rises, and a round pressure gauge reading in psi. It is the low-pressure (L) type, intended where controlled pressure stays below the standard regulator's range, and it ships without a mounting bracket.
This is a genuine AirTAC part from the GFR200 series, one of four sizes (200/300/400/600) with ports from 1/8 in to 1 in and options including manual or automatic drains, 40 um or 5 um elements, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure against 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.

| 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. |
| G | G (BSPP) 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.

Feeding clean, low-pressure air to lab analysers and sample-handling pneumatics, where the 5 um element protects sensitive components and the psi gauge gives a direct local reading.
Conditioning and regulating air at the drop to paint guns on a finishing line, combining water and particulate removal with the gentle pressure control a low-pressure type provides.
Supplying filtered, regulated air to pilot-operated process valves and positioners on a small skid, with the differential-pressure drain keeping condensate off the pilot circuit.
Start with the port: this unit is G1/4 (1/4 in) in the size-200 body, so match it to the line size and the flow your circuit needs - larger sizes (300/400/600) carry more flow at the cost of space. The 5 um element (code W) suits instruments, paint and sensing circuits that tolerate less particulate than the 40 um standard; the differential-pressure drain is the fit-and-forget choice where a manual or fully automatic drain is not wanted. The round psi gauge is fitted as specified; embedded square gauges and MPa or bar scales are alternatives in the series. Thread is G (BSPP) here, with PT standard and NPT available to order, and a bracket can be added if this J-coded (no-bracket) unit needs panel fixing. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 flow for the GFR series as performance curves, not as a single rated number, so we do not quote a figure here. Send us your line size and air demand and we will confirm the flow curve and correct sizing from the datasheet on request.
The L in the code marks the low-pressure regulator variant, intended for circuits controlled below the standard type's range. The exact adjustment window for the low-pressure GFR is not published in the material we hold, so confirm your set pressure with us and we will verify suitability from the datasheet before you order.
