The AirTAC GFR20008F2W AirTAC Filter Regulator 1/4 in PT, 5 um 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 GFR20008F2W is a filter regulator: it removes water and particulate from compressed air and sets a stable downstream working pressure in one compact body. This 200-size unit is threaded PT1/4 (1/4 in), carries the fine 5 um filter element (code W, versus the standard 40 um), and drains condensate automatically by differential pressure, so no manual draining routine is needed. The fitted square gauge reads in psi, and the standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, automatic or manual drains, 40 um or 5 um elements, and gauge or no-gauge variants. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing on request.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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.

Filtering and regulating the shop-air feed to a machining centre's pneumatic tool-changer and clamping circuits, with the 5 um element protecting precision valves from fine particulate.
Conditioning the air feeding carton-sealing and taping heads on a packaging line, holding a steady regulated pressure so cylinders cycle consistently through each shift.
Mounted at the inlet of a robot-cell pneumatic panel, cleaning the supply and setting gripper pressure locally, with the psi gauge giving operators a clear setpoint readout.
Start with the port step: this unit is 1/4 in PT, so match it to your line size and check that the 200 frame suits the air demand at your working pressure - we will confirm flow against the published curves before you order. This configuration already fixes the fine 5 um element and the differential-pressure drain; if your air is cleaner, the 40 um standard element costs less to run, and a manual drain suits intermittent-duty installations where an auto drain is unnecessary. The square psi gauge is fitted here; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available to order, and a mounting bracket is included.
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 flow for the GFR series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your working pressure and air demand and we will confirm the flow and sizing from the datasheet on request before you order.
The W in the code GFR20008F2W selects the fine 5 um element instead of the 40 um standard, which suits air feeding sensitive valves or instruments. The blank drain position is the differential-pressure drain, which bleeds condensate automatically as flow passes through, so no manual drain routine is required.
