The AirTAC GFR20008JF2WGK AirTAC Filter Regulator G1/4, 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 GFR20008JF2WGK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration carries a G1/4 (1/4 in) port, the finer 5 um filter element (code W, versus the 40 um standard), a differential-pressure drain, an embedded square gauge scaled in psi, and a built-in reverse/check valve. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl is polycarbonate (PC), and no mounting bracket is fitted (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and is offered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, MPa/psi/bar gauge scales, and PT, G or NPT threads. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application 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.

Conditioning the 1/4 in branch line that feeds solenoid valves and pneumatic actuators on a machining centre: the 5 um element strips water and fine particles, the regulator holds a steady set pressure, and the check valve prevents backflow when the main supply drops.
Feeding filtered, regulated air to the cylinders and grippers on a carton erecting and sealing line. The square psi gauge lets line staff verify the set pressure at a glance, and the differential-pressure drain deals with collected condensate as part of normal operation.
A point-of-use filter regulator ahead of analytical instruments or test rigs fed from a shop-air drop: the 5 um grade cleans the air, the regulator sets the instrument's working pressure, and the psi gauge gives a local reading for calibration checks.
Sizing starts with the port step: GFR200 carries G1/4 here, while GFR300, GFR400 and GFR600 step up to larger ports and higher flow, so match the size to the air demand of the circuit. This unit already fixes several choices: 5 um filtration (the 40 um standard grade is available where finer filtration is not needed), a differential-pressure drain (automatic and manual drains are order options), a square gauge scaled in psi (MPa and bar scales, and an external round gauge, are also available), a G thread (PT is the standard; NPT can be ordered), and a reverse/check valve (omit it by ordering without the K code). No bracket is fitted; brackets are optional.
Because rated flow is published only as curves, not as a single number, send us your application details 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the datasheet flow figures for this 1/4 in unit on request.
The standard GFR element is 40 um; the W code on this model specifies the finer 5 um element, which removes smaller particles before conditioned air reaches downstream valves, cylinders and instruments. If your line does not need fine filtration, the 40 um standard grade is available to order.
