The AirTAC GFR200-06 AirTAC Filter Regulator G1/8, 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 PT1/8" 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 GFR200-06 is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size-200 unit carries a G1/8 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an embedded square gauge reading in psi is fitted so the set pressure is visible at a glance. A reverse/check valve is fitted, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of thread (PT standard, G and NPT as catalogue options), drain type, filter grade, gauge scale and reverse valve. Published flow data appears as curves rather than a single rated figure, so we confirm flow and other datasheet values for your application on request.

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.

On a machine-tool clamping circuit, the GFR200-06 cleans the supply to 5 um, holds a repeatable clamping pressure via the psi gauge, and the check valve holds the set pressure if the upstream supply dips.
Feeding a packaging machine's valve island, the 5 um element protects solenoid valves from particulate and condensed water while the regulator keeps actuation pressure stable across the shift.
On a lab test bench or instrument air take-off, the fine 5 um grade and steady regulated output give clean, predictable air to sensitive gauges and pilot devices, with the psi gauge making the set point visible.
Size and port set the capacity: this is the smallest GFR size (200) with a G1/8 port, so step up to 300/400/600 if your line needs more flow - we will check the catalogue flow curves against your demand before you order. The 5 um element (code W) is the right choice where finer dirt and water carryover matter, such as downstream of sensitive valves or instruments; the standard grade is 40 um. The differential-pressure drain needs no manual attention but relies on a sufficient pressure differential to purge, so if your duty is low-flow or intermittent, ask us about automatic or manual drain variants. The fitted square gauge reads in psi; MPa and bar scales are also available. G thread is the order option here - PT is the standard thread and NPT is also a catalogue choice. The bracket is included with this code.
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 GFR flow performance as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your application's flow and pressure demand and we will confirm sizing against the datasheet curves before you order.
The standard GFR element is 40 um, which suits general plant air. The W code on this model fits a 5 um element for finer filtration where downstream valves, cylinders or instruments need cleaner air. If your line runs intermittent or very low flow, also ask us about automatic or manual drain variants instead of the differential-pressure drain fitted here.
