The AirTAC GFR20006MLC2WK AirTAC Filter Regulator PT1/8, 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 PT1/8" 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 AirTAC GFR20006MLC2WK is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is built for low-pressure duty, with a 5 um filtering element for finer air cleaning than the standard 40 um grade, a manual drain you open by hand to empty collected condensate, a built-in reverse (check) valve that holds downstream pressure when the supply is lost, and a round pressure gauge reading in psi. The PT1/8 (PT 1/8 in) port suits compact air-prep points on smaller lines and machines.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, drain types, filter grades, gauge styles and scales. 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 we confirm the datasheet and flow figures for your application 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.

| 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. |

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.

On a cartoning or wrapping line where actuators run at reduced pressure, this filter regulator cleans the supply to 5 um and holds a stable low-pressure setting, with the check valve keeping the circuit pressurised during brief supply dips.
Feeding pneumatic sensors, transmitters or small lab apparatus that need clean, finely filtered air at a gentle regulated pressure, with the psi gauge giving a clear local reading and the manual drain emptied during scheduled checks.
Ahead of paint or coating guns, the 5 um element strips water and fine particulate that would spoil finishes, while the low-pressure regulator dials in the gentle atomising pressure the gun specification calls for.
Size and port set the capacity envelope: GFR200 with its PT1/8 port is the compact step of the range, so step up to 300/400/600 where the application demands larger ports and flow. Because flow is published as curves, not a single rated number, ask us to confirm sizing against your required flow before ordering. Note the drain choice: manual drain (as on this model) means an operator opens the bowl drain periodically, while automatic and differential-pressure drains discharge condensate without attention - choose manual only where someone can service the unit routinely. The 5 um (W) element on this model suits finer air-cleaning duty; the standard grade is 40 um. The gauge here is the external round type with a psi scale (MPa and bar scales are also available). Thread is PT as standard; G (BSPP) and NPT are catalogue options to order, and a mounting bracket is included.
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 G-series flow as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your required flow and working pressure and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain: condensate collected in the PC bowl is emptied by opening the drain by hand, which suits stations visited during routine maintenance. If unattended condensate removal is needed, automatic or differential-pressure drain versions are available in the GFR series. The K in the code means a reverse (check) valve is fitted, holding downstream pressure if the upstream supply is interrupted.
