The AirTAC GFR20008MLC2WGK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20008MLC2WGK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and reduces pressure to the working set point in one body. This configuration has a G1/4 (1/4 in) port, a 5 um filter element (code W; 40 um is the standard grade), a manual drain for scheduled bleeding of the bowl, a round external gauge reading in psi, and a reverse (check) valve. The L code selects the low-pressure regulator type, for applications whose set point sits below the standard range. The bowl on this 200 size is polycarbonate (PC), and the mounting bracket is included.
It is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, plus drain, filter-grade, gauge and thread options, and a max inlet pressure of 1.0 MPa (145 psi). Operating temperature for this unit is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm flow and other datasheet figures 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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, reduced-pressure air for label-blow and air-assist nozzles on a bottling line; the 5 um element keeps water and particulate out of the nozzles, and the manual drain lets maintenance bleed the bowl during scheduled changeovers.
Supplies clamping cylinders on a CNC fixture from the shop air header at a reduced, low set pressure; the fitted check valve guards against reverse flow and the round psi gauge gives operators a direct set-point reading.
Runs air-jet blow-off nozzles that clear dust and stray film from cartons on a packaging conveyor at low pressure; the manual-drain PC bowl is bled during line cleaning and the included bracket mounts the unit at the machine frame.
The real choices in this series are decodable from the code: size (200/300/400/600) sets the port and capacity step - here 200 with a G1/4 port; drain type (manual here, automatic or differential-pressure available); filter grade (5 um here, 40 um standard); gauge type and scale (round, psi here; the embedded square gauge is standard); thread (PT is the standard, G and NPT are order options); bracket; and the L low-pressure regulator type.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure and air demand and we will confirm sizing against the datasheet on request.
It selects the low-pressure regulator type, intended where the working set point sits below the standard range. The exact adjustment range for the low-pressure type is not published in the catalogue we transcribe, so ask us and we will confirm it from the datasheet.
