The AirTAC GFR200-08T AirTAC Filter Regulator NPT 1/4, 5 um is a genuine G-series filter regulator: water separation, 5 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 AirTAC GFR200-08T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 200 with 1/4 in NPT ports, fitted with a 5 um filter element (the W grade; 40 um is the standard element), a differential-pressure drain (the catalogue default) and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), the polycarbonate bowl suits the 200 size, the operating temperature range is -5 to 70 C (non-freezing), and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the range include automatic or manual drains, a 40 um or 5 um element, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, G, NPT or PT threads, and an optional bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the 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 a small bench-mounted pneumatic press: the 5 um element strips water and fine particles from the shop-air line before they reach the valve and cylinder, while the regulator holds the set working pressure for repeatable forming.
Point-of-use preparation for carton-sealing and case-packing cylinders on a packaging conveyor: one body filters the line and regulates it, so each station sees clean air at its set pressure.
Conditioning compressed air for laboratory apparatus and analytical instruments that need finer-than-standard filtration: the 5 um grade and a stable regulated supply protect sensitive pneumatic controls.
Choose the size by port and required flow: size 200 carries 1/4 in ports, and stepping up to 300, 400 or 600 gives larger ports and more flow. Drain type is a real choice - this unit uses the differential-pressure drain (the default); automatic (A) or manual (M) drains can be ordered instead. Filter grade is likewise a choice: 40 um is standard for general shop air, while the 5 um grade on this unit (code W) suits finer duty. Gauges come as an embedded square gauge or an external round gauge, in MPa, psi or bar scales - this unit carries a round psi gauge. Threads: PT is the standard; G (BSPP) and NPT are catalogue options to order, and this unit is specified NPT. Brackets are optional, and this unit is ordered without one.
Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 number here. Send us your application - port size, working pressure and air demand - and we will confirm the sizing from the datasheet on request.
40 um is the standard grade for general shop air. The 5 um W grade fitted to this unit suits applications that are more sensitive to fine contamination, such as painting, instrumentation and precision pneumatic components. Both grades are available across the GFR range, and drain, gauge, thread and bracket options can be combined freely when ordering.
