The AirTAC AirTAC GFR20008LF2WGK Filter Regulator 1/4 in Low-Pressure 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 AirTAC GFR200 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body, with no lubricator. This configuration is the 200 size with a 1/4 in G-thread port, the low-pressure regulator type, a 5 um filter element (code W), a differential-pressure drain and an embedded square gauge scaled in psi. A reverse/check valve is fitted and a mounting bracket is included. The bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GFR series runs from 200 through 600 sizes with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale options and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

|---|---|
| 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. |
| 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.

Feeds clean, regulated air at low set pressures to pneumatic clamps on a bench fixture, with the 5 um element keeping particulate out of the clamp cylinders and the check valve holding the circuit if supply dips.
Conditions the air feeding a carton-sealer or wrapper section that runs at reduced pressure, combining water and particle removal with regulation in one 1/4 in port body on the machine's air drop.
Prepares air for lab actuators and small process manifolds where the 5 um grade protects sensitive components, the psi-scaled gauge gives a readable setpoint, and the bracket mounts the unit to the rig frame.
Pick the size by the port and air demand of your line: this 200 unit carries a 1/4 in port, while 300, 400 and 600 step up in port and capacity. The L in the code marks the low-pressure regulator variant, intended for lower set pressures than the standard type; the exact range for this variant is not published, so confirm your set pressure with us before ordering. Drain here is differential-pressure (the default); automatic (A) and manual (M) versions exist. Filtration is the finer 5 um element (W); 40 um is the standard choice when fine filtration is not needed. The embedded square gauge is scaled in psi, with MPa and bar scales and an external round gauge available as options. Thread is G here; PT is the standard and NPT is an orderable option. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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.
Flow for the GFR200 is published as curves in the AirTAC datasheet rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure regulator variant, intended for lower set pressures than the standard type; the exact range for this variant is not published, so confirm your set pressure with us before ordering. W marks the 5 um filter element, one grade finer than the 40 um standard. Inlet pressure is rated to 1.0 MPa (145 psi) and the unit works from -5 to 70 C, non-freezing.
