The AirTAC GFR200C08MC3WTK AirTAC Filter Regulator NPT1/4 5um 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 GFR200C08MC3WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single size-200 body with a 1/4 in NPT port. This configuration carries the fine 5 um filter element (code W), a manual drain for the polycarbonate bowl, a reverse/check valve (code K), and a round pressure gauge with a bar scale. The standard regulator covers 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). A mounting bracket is included.
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 (40 um standard or 5 um), gauge style and scale, thread (PT standard, G or NPT), bracket and check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Cleaning and regulating the shop-air feed to a machining centre's tool-change cylinders and pneumatic clamps, with the 5 um element protecting fine pilot valves and the bar gauge giving the operator a direct setting reference.
Conditioning the air feeding sealing jaws and carton-forming cylinders on a packaging line, where the 5 um grade keeps moisture and fine particles out of sensitive valves and the check valve holds the downstream setting if supply dips.
Supplying clean, regulated air to bench-top test rigs and analytical equipment, where the fine 5 um filtration, bar-scaled gauge and manual drain suit a supervised, intermittently attended setup.
Size 200 with a 1/4 in port is the entry step of the GFR range; step up to 300, 400 or 600 when your line needs more flow or a larger connection. Because flow is published only as curves, not a single rated figure, send us your air demand and we will confirm the right size before you order. The 5 um element (code W) suits instruments and precision actuators; the 40 um standard element is the usual choice for general plant air. The manual drain needs periodic operator attention, which suits intermittently attended installations; automatic or differential-pressure drains are available on other codes. This code includes a round gauge with a bar scale (MPa, psi and bar scales exist), a reverse/check valve, and a mounting bracket. NPT thread is specified here; PT is the catalogue standard and G (BSPP) is also orderable.
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 number, so we do not quote a figure here. Tell us your application's air demand and we will confirm the sizing and the datasheet flow curve for this exact code on request before you order.
Code M in the drain position specifies a manual drain: the accumulated condensate in the polycarbonate bowl is released by hand, which suits installations that are checked regularly; automatic and differential-pressure drains are available on other GFR codes. Code W sets the 5 um filter element, finer than the 40 um standard element, for air feeding precision valves and instruments.
