The AirTAC GFR20008C3TK AirTAC Filter Regulator, NPT1/4, Bar Gauge 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 GFR20008C3TK is an AirTAC GFR200 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is the size 200 unit with a 1/4 in NPT port, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The built-in regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a round external gauge scaled in bar is fitted, and a reverse/check valve is installed so downstream pressure is held if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl gives a clear view of condensate level, and a mounting bracket is included.
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, manual, automatic or differential-pressure drains, a 5 um (code W) element option, gauge and thread variants, and low-pressure regulator types. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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.

Feeding clean, pressure-controlled air to a bench-mounted pneumatic press on an assembly line: the 40 um element keeps swarf and moisture out of the valve train, the regulator holds a repeatable setting for consistent forming, and the check valve holds the circuit if plant air drops.
Supplying the carton-forming and sealing stations of a bottling hall packaging line, where a 1/4 in NPT drop feeds actuators that need steady, filtered air. The differential-pressure drain keeps condensate moving out of the polycarbonate bowl without operator attention, and the bar gauge lets line staff verify the set pressure at a glance.
Conditioning the shop-air feed inside a CNC machine tool's electrical-pneumatic cabinet: filtered and regulated air to the tool-changer and pallet-clamp circuits, with the reverse/check valve preventing pressure loss during supply dips and the included bracket mounting the unit neatly inside the cabinet.
Work through the real, decodable choices before ordering. Size 200 with a 1/4 in port suits lighter duty lines; step up to 300, 400 or 600 for larger ports and more flow. Drain: this unit uses the differential-pressure drain (the default); choose automatic (code A) for hands-off condensate removal or manual (code M) where you want positive control. Filter grade: the fitted 40 um element is the standard choice; specify 5 um (code W) if the downstream equipment needs finer filtration. Gauge: this version carries a round external gauge scaled in bar; embedded square gauges and MPa or psi scales are alternatives. Thread: this unit is NPT; PT is the standard thread and G (BSPP) is a catalogue option to order. A reverse/check valve (code K) is fitted on this unit, and the mounting 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 rather than a single rated figure, so we do not state one number. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet flow figures for this exact unit on request before you order.
K means a reverse/check valve is fitted. If upstream supply pressure falls away, the valve holds the regulated downstream pressure instead of venting it back through the unit - useful on circuits where a momentary plant-air dip must not dump a set pressure. Units without the K code do not have this valve.
