The AirTAC GFR200C08C1TK AirTAC Filter Regulator NPT1/4 Round 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 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 GFR200C08C1TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 200-size unit is threaded NPT1/4 (1/4 in), carries the standard 40 um filter element, and drains condensate by differential pressure, so it needs no drain fitting or manual attention beyond normal service. A check valve (reverse-flow function, code K) is fitted, an external round gauge with an MPa scale is specified, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate (PC) bowl suits this size; only the 600 size uses an aluminium alloy bowl.
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, optional 5 um filtration (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT thread options, and a low-pressure regulator variant. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures 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.

Feeding clean, pressure-controlled air to clamping cylinders and pneumatic presses on a machining cell, where the regulator holds a consistent clamping force and the 40 um element protects directional valves from particulate.
Conditioning supply air at the inlet of form-fill-seal or cartoning equipment, where the filter regulator protects the machine's valve island and actuators from water and debris while holding the working pressure the cycle was set up with.
Dropping a regulated, filtered air take-off at individual conveyor zones or pick-and-place stations, where the check valve holds the set pressure against backflow and the differential drain keeps condensate off the downstream cylinders.
Choose the GFR200 size and its 1/4 in port by matching the flow demand of your line against the published flow curves - not against a single rating - and step up to GFR300/400/600 if your air consumption is higher. This unit uses the standard 40 um element, which suits general plant air; specify the W code for 5 um filtration where finer protection is needed. The differential-pressure drain fitted here is the low-maintenance default; automatic drain (A) or manual drain (M) versions are available if your duty or service access calls for them. The round MPa gauge matches this code; square gauges and psi or bar scales can be ordered instead, and G (BSPP) or NPT threads are catalogue options alongside the PT standard. A bracket is included with this unit. 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your working pressure and air demand and we will confirm the flow from the datasheet curves for your application before you order.
The K code means a reverse (check) valve is fitted, so downstream pressure is held against backflow at the inlet. The C1 code specifies an external round gauge with an MPa scale; the embedded square gauge is the standard fitting, and psi or bar scales can be ordered instead if you prefer.
