The AirTAC GFR200-08 AirTAC Filter Regulator, G1/4, Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is specified with a G1/4 (BSPP) port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, a low-pressure regulator type, an embedded square gauge scaled in psi, and a built-in reverse (check) valve that holds downstream pressure when the supply is cut. Mounting bracket included.
This is a genuine AirTAC part from the GFR series, which spans 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, thread choices of PT (standard), G and NPT, manual, automatic or differential-pressure drains, and an optional 5 um element (code W). We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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.

| (blank) | Filtering grade 40 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. |

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 and regulates the air to a pick-and-place gripper where the low-pressure regulator type and check valve hold the set pressure at the gripper when the main supply is shut off between cycles.
Conditions and regulates the instrument air feeding positioner and pilot stages on a control valve skid, with the 40 um element keeping particulate out of small pilot orifices.
Supplies filtered, regulated air to the cylinders that raise, lower and divert product on a packaging line, with the differential-pressure drain handling condensate without operator attention.
Size and port set the flow path: this 200-size unit carries a G1/4 (BSPP) port; step up to 300, 400 or 600 when the application needs a larger port and more flow. The 40 um element is the standard grade for general plant air; specify the W suffix for the 5 um grade where finer filtration is needed. Drain choice matters: differential-pressure (as fitted here) needs no attention during operation, automatic drains continuously, and manual requires periodic bleeding. The square gauge is scaled in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G here, with PT as the catalogue standard and NPT available to order; a bracket is included.
Because flow is published as curves rather than 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.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for the GFR200-08 on request before you order.
The K suffix in GFR20008LF2GK means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply drops. The F2 suffix specifies the embedded square gauge scaled in psi; MPa and bar scales, or an external round gauge, are catalogue alternatives.
