The AirTAC GFR200C08F3WTK AirTAC Filter Regulator NPT1/4, 5 um 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 See datasheet 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 GFR200C08F3WTK is a size-200 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 1/4 in NPT port, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge scaled in bar, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjustment range is 0.15-0.9 MPa (20-130 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread form (PT standard, G and NPT as order options) and check valve. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

On a CNC machining centre, the unit filters the shop air feeding the clamping circuit and holds a set clamping pressure, while the check valve keeps fixtures clamped if the main supply drops.
On a carton packaging line, the regulator sets stable pressure for pick-and-place cylinders and vacuum generators, and the 5 um element protects the small valves that control them.
For benchtop lab equipment and analytical instruments, the unit conditions the instrument air supply, with the bar-scaled gauge giving a clear local pressure reading at the point of use.
Start with the port step: GFR200 in 1/4 in suits lighter duty circuits; step up to GFR300/400/600 for larger ports and higher flow demand. This unit already carries the finer 5 um element (W); the standard grade is 40 um if your application does not need the finer filtration. Drain choice matters: differential-pressure (fitted here) drains with flow, automatic (A) drains on a cycle regardless of flow, and manual (M) drains only when opened. Gauge options are the embedded square gauge (scales MPa, psi or bar - this unit is bar) or an external round gauge; N omits the gauge. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and J removes the bracket. Because flow is published as curves rather than a single rating, 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. 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, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing for you before you order.
The W in the code selects the 5 um filter element instead of the 40 um standard grade, for finer protection of downstream components. The K adds a reverse/check valve, which holds the set downstream pressure if the upstream supply is interrupted. Both are standard catalogue options on the GFR family.
