The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This size 200 unit has a 1/4 in NPT port, a 5 um filter element (the finer of the two grades), and a differential-pressure drain, the catalogue default. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), an embedded square gauge with a psi scale is fitted, and a reverse/check valve is built in to hold downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing. The bowl on this size is polycarbonate, and this configuration (code J) comes without a mounting bracket.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G and NPT as orderable options, 40 um standard or 5 um filtration, manual, automatic or differential-pressure drains, and MPa, psi or bar gauge scales. Flow for these units is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air to pneumatic clamps and tool-changer cylinders on a machining centre, with the 5 um element suiting fine-seal actuators and the check valve holding the circuit if the supply dips.
Point-of-use supply for sorting and diverter cylinders on a packaging conveyor, where one body handles both filtering and regulation ahead of the directional valves.
Regulated air for pick-and-place and sample-handling actuators in laboratory automation, with the local psi gauge giving operators a clear setpoint readout at the station.
Size and port: 200 is the compact step in the GFR range; step up to 300, 400 or 600 for larger ports and more flow, and match the port to your piping. This unit is 1/4 in NPT; PT and G threads are orderable options. Drain: differential-pressure is fitted here; automatic (A) and manual (M) drains are available in the range. Filtration: this unit carries the 5 um element (W); the 40 um standard grade suits general shop air. Gauge: an embedded square gauge with a psi scale is included, with MPa or bar scales and an external round gauge as options. A reverse/check valve is fitted (K) and no mounting bracket is included (J). Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR range as curves rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
This unit carries the W-code 5 um element; the GFR range default is 40 um for general shop air. Choose 5 um where downstream valves and actuators need finer filtration, or order the version without the W code for 40 um. Both share the same body, port and regulation range.
