The AirTAC GFR20008MLJNWT AirTAC Filter Regulator NPT1/4, 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 AirTAC GFR20008MLJNWT is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single compact body. This configuration is the 200 size with 1/4 in NPT ports, a fine 5 um filter element (code W), a manual drain for scheduled bowl draining, and the low-pressure regulator type for circuits that run below standard line pressures. It is supplied without a gauge and without a mounting bracket, and no reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, optional gauges, and PT, G or NPT threads. Flow figures for this family 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 fixture-clamping manifold that runs below standard shop-air pressure, this low-pressure-type filter regulator cleans the air to 5 um and holds the reduced setting, with the manual drain emptied during shift checks.
Feeding the small pick-and-place cylinders on a carton-sealing line, the 1/4 in NPT connection drops straight into the machine's air preparation point, the 5 um element protects the directional valves, and the manual drain is cleared at end-of-shift housekeeping.
On a laboratory or pilot-line air sub-panel where instruments need fine-filtered, reduced-pressure air, this unit combines filtration and regulation in one body, and the manual drain suits the supervised environment.
Start with the port step: this unit is the 200 size with 1/4 in NPT ports; larger GFR sizes (300/400/600) carry bigger ports and suit higher air demand, so match the size to the line rather than upsizing blindly. Choose the drain to match maintenance habits: manual drain (this unit) needs an operator to open the bowl drain at intervals, while automatic and differential-pressure drains discharge condensate without a hands-on step. Filtration is 5 um here (code W) instead of the standard 40 um - pick 5 um where downstream valves and instruments are sensitive to fine particles. Gauges, bracket, thread (PT standard, G or NPT to order) and reverse valve are all selectable across the range.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated figure, so we cannot quote a flow number here. Send us your application details and we will confirm the correct size against the datasheet curves 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 family as characteristic curves rather than a single rated figure, so we do not quote a flow number. Tell us your application - line pressure, downstream demand and acceptable pressure drop - and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects the manual drain: condensate collected in the polycarbonate bowl is released by opening the drain fitting at the bottom, on a schedule you set. If nobody is available to drain the bowl regularly, the same GFR size is available with an automatic or differential-pressure drain instead - just ask for the alternative code.
