The AirTAC GFR200-08T AirTAC Filter Regulator, NPT1/4, Low-Pressure 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 AirTAC GFR200-08T is a filter regulator: water and particulate filtration plus pressure regulation combined in a single 200-size body. This configuration is threaded NPT1/4 (1/4 in), carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl empties itself as the pressure differential builds during normal operation. It is the low-pressure (L) regulator type, and this code specifies an external round gauge with a bar scale. The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and maximum inlet pressure is 1.0 MPa (145 psi). 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, and is ordered with a choice of drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, G and NPT as options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 low-pressure pneumatic cylinder or air table on a machine-tool drop, where the unit filters condensed water and pipe scale out of the shop supply and holds the reduced working pressure the actuator was sized for.
Conditioning the compressed air feeding lab analysers, sample-handling actuators or pneumatic stirrers, where the 40 um element keeps particulates out of sensitive components and the low-pressure regulator type matches the modest supply pressure these instruments run at.
Supplying the stopper, pusher and gating cylinders on a packaging or bottling conveyor, filtering water carried over from the compressor and regulating a stable, reduced pressure so product handling stays gentle and repeatable.
Start with the size and port: 200 is the smallest GFR frame, and the step up to 300, 400 or 600 buys larger ports and more flow, so match the frame to the air demand of the circuit rather than to the pipe alone. Choose the drain to suit access: differential-pressure (this model) drains itself in service, automatic suits unattended installations, and manual suits points an operator visits anyway. Filter grade is 40 um standard; specify the W option for 5 um where downstream equipment needs finer filtration. Gauge style and scale are decodable: this unit carries a round gauge on a bar scale, while an embedded square gauge with MPa, psi or bar scales is the standard alternative. Thread is PT as standard with G (BSPP) and NPT as order options; this model is NPT. A bracket is included on this code. Because flow is published as curves and not a single rating, 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 G-series flow as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your application details and we will confirm the flow figures from the datasheet so you can check the 200 size and the NPT1/4 port against your air demand before ordering.
L marks the low-pressure regulator type, intended where the reduced working pressure is well below the standard range; the exact adjustment range for the low-pressure type is not published, so ask us to confirm it on request. The drain on this model is differential-pressure: there is no drain code, and the bowl discharges condensate automatically as the pressure differential builds, with no manual draining needed.
