The AirTAC GFR200C08NTK AirTAC Filter Regulator NPT1/4 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 GFR200C08NTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This unit is the size 200 frame with a 1/4 in NPT port, standard 40 um filtration, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The built-in check (reverse) valve holds downstream settings if upstream supply is interrupted. Outlet pressure is adjustable over 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures of -5 to 70 C (non-freezing). No gauge is fitted in this configuration, so add a gauge separately if a visual pressure readout is required.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration grades, gauge and bracket options, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow data for your exact operating conditions 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.

Point-of-use conditioning for a machining centre's pneumatic actuators and tool-change clamps: the filter stage strips water and chips-laden particulate from the shop-air drop, while the regulator holds a steady clamp pressure and the check valve keeps the setting if the main supply dips.
Feeding air cylinders on a carton packaging conveyor, where clean, dry-ish air at a stable pressure keeps diverters and sealing jaws cycling consistently. The differential-pressure drain sheds accumulated condensate without a manual walk-round, and the 40 um element protects directional valves.
A workbench drop on a factory assembly line running air tools and small actuators: the GFR200C08NTK filters the incoming supply, regulates it to the station's working pressure, and the built-in check valve prevents backfeed between adjacent stations sharing a header.
Start with the port and size step: this unit is size 200 with a 1/4 in NPT port, and the GFR range steps up through 300, 400 and 600 as flow demand grows - match the step to your line's air consumption rather than port size alone. Choose the drain to suit access: this configuration uses the differential-pressure drain (the default), while automatic (A) and manual (M) drains are available if your duty or maintenance routine calls for them. Filtration is the standard 40 um grade; specify the W variant for 5 um if downstream equipment needs finer protection. Note that no gauge is fitted (code N) and a check valve is included (code K); gauge, scale and bracket options can be selected on other configurations. Thread is NPT here, with PT as the catalogue standard and G (BSPP) also available to order. Flow is published as curves, not a single rating, so 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. 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 performance curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your inlet pressure, set pressure and required air consumption, and we will confirm the flow data from the datasheet for this exact model before you order.
The N in GFR200C08NTK means no pressure gauge is fitted; gauge options (round or square, with MPa, psi or bar scales) are available on other GFR configurations if you want a visual readout. The K means a reverse (check) valve is fitted, which holds the downstream pressure setting if the upstream supply is interrupted.
