The AirTAC GFR20008MLJF1WTK AirTAC Filter Regulator NPT1/4 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 GFR20008MLJF1WTK is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is decoded as a 1/4 in NPT port, a 5 um filter element (the finer of the two published grades), a manual drain on the polycarbonate bowl, a low-pressure regulator type, a reverse/check valve fitted, and an embedded square gauge with MPa scale. The manual drain means an operator opens the bowl drain to expel collected condensate, so it suits installations visited regularly rather than unattended lines. The reverse/check valve holds downstream pressure if the upstream supply is interrupted.
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, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge and scale options, and PT (standard), G or NPT threads to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| 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.

A CNC fixture that clamps workpieces with air cylinders at a held, lower regulated pressure. The GFR unit filters chips-and-water-laden shop air to 5 um before the valve bank, the check valve holds clamp pressure during a supply dip, and the square gauge lets the setter read regulated pressure directly.
A carton-sealing or wrapping machine running small air cylinders and grippers off a shop header. The low-pressure regulator type suits circuits run below standard line pressure, the 5 um element protects the machine's directional valves, and the manual drain is emptied during each shift changeover.
A bench-top coating, dosing or sample-handling rig where sensitive pneumatic components need clean, gently regulated air. The 5 um grade limits particulate carryover, the polycarbonate bowl shows collected condensate at a glance, and the MPa gauge supports repeatable daily setup.
Start with the port and size step: GFR200 with a 1/4 in NPT port is the smallest published size, so match it against the air demand of the machine it feeds - if your consumption sits near or above the top of the size-200 flow curve, step up to GFR300 or larger. This unit carries the 5 um element (code W); choose it where downstream valves and cylinders need finer filtration than the 40 um standard, accepting that the finer element loads faster and the manual drain must be operated routinely. The low-pressure regulator type is intended for circuits regulated below the standard range - we will confirm the exact adjustment range from the datasheet on request. The square gauge is fitted with an MPa scale; psi and bar scales and an external round gauge are options. Thread here is NPT; PT is the standard and G is also an order option. No mounting bracket is included with this code (J), so plan your panel or manifold fixing accordingly.
Because AirTAC publishes flow as curves and not a single rating, send us your line pressure and air demand and we will confirm sizing 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, not as a single rated number, so we do not quote a figure here. Send us your inlet pressure and the air consumption of the equipment you are feeding, and we will confirm the sizing against the datasheet curves before you order.
This code ends its drain position with M, which decodes to a manual drain: an operator opens the bowl drain to release collected water. It is the right choice where the unit is visited regularly, such as a machine serviced each shift. For unattended lines, the automatic (A) or differential-pressure (blank) drain options in the same family remove the routine task - we can quote those variants on request.
