The AirTAC GFR20008LC2WG 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 GFR20008LC2WG is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one compact body. This unit is built in the 200 size with a G1/4 (BSPP) port, the finer 5 um filter element (the W grade, against the 40 um standard), a differential-pressure drain, and the low-pressure regulator type. A round pressure gauge scaled in psi is fitted, the mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the polycarbonate bowl suits the 200 size.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

| (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. |

| 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.

Filtered, low-pressure regulated air to pick-and-place cylinders and sealing jaws on a cartoning or wrapping line, with the 5 um element protecting small valve internals downstream.
Stable low-pressure air for sample-handling cylinders and grippers on analytical or dispensing equipment, where the fitted round psi gauge gives a direct local reading at the machine.
A finishing-booth gun circuit where moisture and particulate must be stripped before atomizing air is held at a set low pressure; the 5 um element and integral regulation suit the feed.
The real choices on this family: step the size (200/300/400/600) and port (1/8 to 1 in) to match the air your line needs; pick the drain (differential-pressure as here, automatic, or manual); choose 40 um standard or the 5 um W grade fitted on this unit; select gauge style and scale (embedded square or external round, in MPa, psi or bar - this unit carries a round psi gauge); and order the thread you need, since PT is the catalogue standard with G and NPT as options. Regulation here is the low-pressure type; its exact adjustment range is not published, so confirm it with us. Flow is published as curves, not a single rated figure - send us your application 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. 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The W in the code selects the finer 5 um element; the catalogue standard is 40 um, and both grades are available across the GFR sizes, so order the plain code without W for 40 um. This unit also carries the low-pressure regulator type, a round psi gauge, a differential-pressure drain and a G1/4 thread - all decodable from the model code.
