The AirTAC GFR20008MLNWT AirTAC Filter Regulator 1/4 in NPT 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 GFR20008MLNWT is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1/4 in NPT port, a 5 um filter element (one step finer than the 40 um standard), a manual-drain polycarbonate bowl and the low-pressure regulator type. No pressure gauge is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options for drain type, filter grade, gauge and scale, thread (PT standard, G and NPT to order) and bracket. AirTAC publishes flow for this family as curves rather than a single rated figure, so ask us to confirm flow and 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.
| 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. |
| (blank) | Mounting bracket included. |
| 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 carton-forming station, the unit filters and regulates the air feeding short-stroke sealing cylinders; the 5 um element helps protect directional-valve seals, and the manual drain is emptied during changeover.
Feeding paint spray guns, the unit strips water and fine particulate ahead of the gun and holds a steady low set pressure; the manual drain is opened at the end of each shift.
On a laboratory test bench, the low-pressure regulator type suits fixtures that must not see full line pressure; with no gauge fitted on this code, the bench's own calibrated gauge reads the set point.
Size and port: the 200 frame with a 1/4 in NPT port is the entry step of the GFR range; step up through the 300, 400 and 600 frames and larger ports when the application's flow demand outgrows the curve for this size. Filter grade: this unit carries the 5 um element (code W); the 40 um standard element is the usual choice where only coarse protection is needed. Drain: the manual drain (code M) suits attended installations; automatic and differential-pressure drain variants are available in the family. Gauge: none is fitted on this code; gauge-equipped variants with square or round dials in MPa, psi or bar scales can be ordered instead. Thread: NPT on this model, with PT as the standard and G (BSPP) also available to order. A mounting bracket is included. Because AirTAC publishes flow only as curves, ask us to confirm sizing against the application before ordering.
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 G-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your upstream pressure and air consumption and we will confirm the flow from the datasheet for this exact unit before you order.
The M in the code is a manual drain: moisture collected in the polycarbonate bowl is discharged by opening the drain fitting at the bottom by hand. It suits installations checked on a regular schedule; for unattended duty, the GFR family also offers automatic and differential-pressure drain variants.
