The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 5 um Manual Drain 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is built on the compact 200 frame with a 1/4 in NPT port, a 5 um filter element (code W), a manual-drain polycarbonate bowl, an adjustable round gauge reading in bar, and a built-in reverse (check) valve; it is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.05-0.9 MPa (7-130 psi), and the working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and options for drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT to order), 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.

Feeds clean, regulated air to 1/4 in solenoid valves on an assembly-line fixture. The 5 um element and water removal protect valve internals, the regulator sets the circuit pressure, and the check valve holds downstream pressure through upstream dips.
Prepares the air supply for a small bench press cylinder: the regulator lets the operator set and hold the working pressure for consistent forming, while the manual drain bowl is emptied as part of the end-of-shift routine.
Conditions the shop-air feed to a lab test bench where a repeatable set pressure matters. The round bar gauge gives a clear reading, the 5 um grade suits sensitive instrumentation, and the check valve prevents backflow into the supply line.
Size and port step up with flow demand; 200 is the compact frame, here with a 1/4 in NPT port. Choose the drain to suit the duty: manual (this unit, which pairs with the 0.05-0.9 MPa / 7-130 psi regulating range), automatic, or the differential-pressure default. The 5 um element (W) suits finer air-quality needs; the standard element is 40 um. Gauges come as the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries a round gauge reading bar. Thread is PT as standard with G (BSPP) and NPT as orderable options, and the J code deletes the mounting bracket. Because flow is published as curves rather than a single rated figure, 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 curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the datasheet flow curve and correct sizing on request before you order.
The M code specifies a manual-drain bowl: collected water is expelled by opening the drain by hand as part of routine checks. On the catalogue this drain type pairs with a 0.05-0.9 MPa (7-130 psi) regulating range. If you prefer unattended drainage, automatic and differential-pressure drain versions are available in the same size.
