The AirTAC GFR200-08 AirTAC Filter Regulator, PT1/4, 5 um, psi Gauge 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 GFR200-08 is an AirTAC filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is the 200 size with a PT1/4 port, the finer 5 um filter element (code W), a differential-pressure drain, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is shut off. The polycarbonate bowl suits the 200 frame, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 inch and options including automatic or manual drains, 5 um or 40 um elements, square or round gauges with MPa, psi or bar scales, and G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the standard regulation range is 0.15-0.9 MPa (20-130 psi). Rated flow is published as curves rather than a single figure, so ask us to confirm datasheet numbers 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.

Feeding clean, regulated air to the valve stack on a six-axis robot cell, where the 5 um element protects directional valves and the check valve holds the circuit while the supply is isolated.
Regulating pressure to pick-and-place cylinders and vacuum generators on a packaging conveyor, with the square psi gauge letting operators set and verify line pressure at a glance.
Supplying stable, filtered air to bench-top test rigs and pneumatic instrumentation, where fine 5 um filtration and a held downstream pressure keep readings repeatable.
Choose the size by port and required flow: 200 is the compact frame with a 1/4-inch port here, stepping up through 300, 400 and 600 as demand grows. This unit carries the 5 um element (code W) instead of the standard 40 um grade - pick 5 um where downstream equipment needs finer filtration. The differential-pressure drain is the default and needs no day-to-day adjustment; automatic and manual drains are available elsewhere in the family. The embedded square gauge reads in psi, with round gauges and MPa or bar scales as options. Thread is PT as standard, with G (BSPP) and NPT as order choices, and a mounting bracket is included. Because flow is published as curves rather than a single rating, 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 series as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the datasheet figures for this 1/4-inch unit before you order.
The W code fits the 5 um element in place of the standard 40 um grade. Choose it when downstream valves, cylinders or instruments need finer particulate protection; the standard 40 um element remains available elsewhere in the GFR200 series.
