The AirTAC GFR20008F2WGK 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 AirTAC GFR200 series combines water and particulate filtration with pressure regulation in a single body, so one G1/4 (1/4 in) unit cleans the air and holds your set pressure downstream. This configuration, GFR20008F2WGK, carries a 5 um filter element (the finer W grade instead of the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure if the supply is interrupted. The polycarbonate bowl suits this 200 size, a mounting bracket is included, and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is published in four sizes (200, 300, 400 and 600) with port sizes from 1/8 in to 1 in, filter grades of 40 um standard or 5 um optional, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and G, NPT or PT threads. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow 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.

Feeding tool-clamp and chip-clearing cylinders on a CNC machining centre: the 5 um element protects fine valve spools from particulate carryover, the regulator holds a steady clamp pressure, and the check valve keeps clamps from releasing during a supply dip.
Supplying the valve island on a carton-forming packaging line: cleaned and regulated air at a set psi keeps pick-and-place cylinders repeatable, the differential-pressure drain handles condensate on continuous shifts, and the psi gauge lets operators verify setpoint at a glance.
Regulating air to actuated valves and sample-handling actuators on a laboratory automation bench: the 5 um grade suits sensitive pilot circuits, the bracket gives tidy panel mounting, and the check valve holds position if the bench supply is switched off.
Start with the port and size step: this unit is a 200-size body on a G1/4 port, and the larger steps (300, 400, 600) exist for lines that need more flow at the same or larger connection - match the step to the air demand of the circuit rather than upsizing blindly. Choose the drain next: the differential-pressure drain fitted here suits a steadily used line, while an automatic drain (code A) suits intermittent duty and a manual drain (code M) suits dry, supervised installations. This unit already carries the finer 5 um element (W); the 40 um standard grade is the choice where only bulk water and coarse particles matter. The square gauge here reads psi; MPa and bar scales and an external round gauge are the other decodable options. Thread is G (BSPP) on this code - PT is the catalogue standard and NPT is an order option - and the 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 GFR200 series as curves, not as a single rated figure, so there is no one flow number we can honestly quote for this 200-size, G1/4 unit. Tell us your application and required flow, and we will confirm the figures from the datasheet on request before you order.
The W in the code GFR20008F2WGK selects the optional 5 um filter element instead of the 40 um standard grade - the right choice where finer particles must be kept out of downstream valves and actuators. The K selects a built-in reverse/check valve, which holds downstream pressure if the upstream supply is lost. Both are decodable options; the differential-pressure drain, square psi gauge, G thread and included bracket are the other choices locked into this code.
