The AirTAC GFR200-08LF1WTK AirTAC Filter Regulator NPT1/4 5um 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR200-08LF1WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 200-size configuration has a 1/4 in NPT port, a 5 um filter element (code W), a differential-pressure drain, a built-in check valve, and the low-pressure regulator type fitted with an embedded square gauge scaled in MPa. The bowl on this size is polycarbonate (PC), and the mounting bracket is included.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as catalogue options, with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge variants. Flow is published as curves rather than a single rating, 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| 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.

Feeds spray guns and air-assisted applicators from a shop air line, delivering cleaned, dried air with the pressure held gently at the low settings such finishing work calls for.
Sits ahead of clamping cylinders on assembly and welding fixtures, straining out water and swarf and holding a steady, low regulated pressure so parts are held consistently cycle after cycle.
Conditions the air feeding small cylinders and actuators on cartoning and wrapping lines, with the check valve holding the downstream circuit stable if the supply side dips.
Size the unit by port and flow demand: 200 is the compact step of the range and carries a 1/4 in port in this code, while 300, 400 and 600 step up in port and capacity. This code fixes a 5 um element (choose the version without the W suffix for the 40 um standard grade), a differential-pressure drain, a check valve, the low-pressure regulator type and a square MPa gauge; an external round gauge and MPa, psi or bar scales are the catalogue alternatives. Thread is NPT here, PT is the standard and G is an order option, and the mounting bracket is included. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet curve for this 200-size, 1/4 in NPT unit before you order.
L marks the low-pressure regulator type, selected where the circuit runs at gentler pressures than a standard regulator setting. The exact adjustment range for this variant is not published in the catalogue, so we confirm it on request; standard-type GFR units carry the published 0.15-0.9 MPa range with differential-pressure drain.
