The AirTAC AirTAC GFR20006LF2WK Filter Regulator PT1/8 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 PT1/8" 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 GFR20006LF2WK is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is the 200 size with a PT1/8 port, the low-pressure regulator type, a 5 um filter element (code W), and a differential-pressure drain that bleeds collected condensate automatically as flow passes through. The polycarbonate bowl lets you see the condensate level, the embedded square gauge reads in psi, a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and options including manual or automatic drains, the 40 um standard element, alternative gauge scales, G or NPT threads, and check-valve or no-bracket variants. 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.

| 06 | Port size PT1/8". 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. |

| 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. |

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 on a finishing line where air must be both finely filtered (5 um) and regulated at low set pressures, with the psi gauge giving the operator a direct readout at the booth.
Supplies clean, low-pressure air to pilot solenoid valves and small actuators on benchtop lab automation, where the 1/8 inch port, compact 200 body and included bracket suit tight panel mounting.
Regulates filtered air to low-pressure clamping and hold-down cylinders on a packaging conveyor line, with the fitted check valve protecting the set pressure in the downstream circuit.
Start with the port step: the 200 size carries the 1/8 inch port in this code, and the larger 300, 400 and 600 sizes step up in port and flow capacity - match the size to the air demand of the circuit rather than oversizing on price alone. This unit is the low-pressure regulator type, so choose it where the set pressure sits below the standard type's range; the exact range for the low-pressure type is not published, so confirm it with us. You have already selected the 5 um element over the 40 um standard (right for delicate downstream components), the square psi gauge, the differential-pressure drain, the check valve, and the included bracket. Thread is PT as standard; G (BSPP) and NPT are orderable options. Because flow is published as curves and not a single rated figure, 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.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a l/min, SCFM or Cv number here. Tell us your application and we will confirm the flow and datasheet figures for the GFR200 at 1/8 inch on request before you order.
L is the low-pressure regulator type; F2 is the embedded square gauge with a psi scale; W is the 5 um filter element (40 um is the standard alternative); and K means a reverse/check valve is fitted. The blank drain position is the differential-pressure drain, and the missing J means the mounting bracket is included.
