The AirTAC GFR20008MLF2WGK 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 GFR20008MLF2WGK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This 200-size unit is configured with a G1/4 (BSPP) port, a 5 um filter element (the finer of the two published grades), a manual drain on the polycarbonate bowl, and a low-pressure regulator type for circuits that run below standard set pressures. It ships as coded with an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is orderable with manual, automatic or differential-pressure drains, 40 um or 5 um elements, optional external round gauges, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for 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.

|---|---|
| 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). |
| F | Gauge shape: Square. 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.

On a carton-sealing line, the clamp and hold-down cylinders often run at reduced set pressures. This low-pressure filter regulator cleans the supply, holds the reduced setting on the psi gauge, and the check valve holds the circuit if upstream pressure dips.
Analytical enclosures, sample pumps and purge panels need clean, dry, finely filtered air at a stable low setting. The 5 um element protects sensitive components, the manual drain allows a scheduled condensate check, and the psi gauge gives a clear local reading.
Roller loading cylinders and web-tension actuators on converting machinery benefit from one compact unit doing both jobs: the bowl strips water and fines from mill air, the low-pressure regulator sets the gentle force these applications need, and the bracket simplifies panel mounting.
Start with the port step: this unit is 200 size with a 1/4 in port; step up to 300, 400 or 600 if your line needs more flow capacity, and match the thread to your piping (PT is the standard, G and NPT are order options). This code carries the 5 um element rather than the 40 um standard - choose 5 um where downstream equipment is sensitive to fine particulate. The manual drain means an operator opens the bowl drain during checks; pick automatic or differential-pressure drain codes if you want condensate handling without that routine. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is an option. A bracket is included, and the reverse/check valve is already fitted.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm this configuration against the datasheet before you order.
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 rather than a single rated number, so we do not quote a figure here. Tell us your working pressure and required flow and we will confirm against the datasheet whether this 200-size, G1/4 configuration suits your application before you order.
The M in the code specifies a manual drain: an operator opens the bowl drain to remove accumulated condensate during routine checks. If you would rather not rely on that routine, the same family is orderable with an automatic drain (code A) or a differential-pressure drain (the default). This unit also carries the 5 um element instead of the 40 um standard, a square psi gauge, a reverse/check valve and a bracket, all fixed by the code.
