The AirTAC GFR200-06 AirTAC Filter Regulator, NPT 1/8 in, 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 then regulates downstream pressure. This 200-size unit is fitted with 1/8 in NPT ports, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, and a round pressure gauge reading in MPa. A reverse/check valve is fitted, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, drain types, filter grades and gauge options, so a matching unit exists for larger lines and different site standards. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing against 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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Mounted ahead of a machine's directional-valve manifold, it strips water and fine particles from the shop-air line and holds a steady regulated pressure so solenoid valves shift consistently shift to shift.
Fitted at the air inlet of a small CNC or spindle-drivend tool station, it conditions the supply feeding tool-change cylinders and air bearings, with the 5 um element guarding against fine contamination.
Installed on the supply line to benchtop test rigs and analytical instruments, it regulates input pressure to the instrument's specification and the round MPa gauge gives a clear local pressure reading.
Size and port step up with required flow: 200 is the smallest GFR frame, and this unit carries it on 1/8 in NPT threads. The 5 um element (code W) suits air that feeds sensitive components; the standard 40 um grade is fine for general lines. Drain is differential-pressure here - automatic (A) and manual (M) versions exist if your site prefers them. The round gauge reads MPa; psi and bar scales are catalogue alternatives, as is the embedded square gauge. Threads come as PT (standard), G or NPT, and the bracket is included.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 as performance curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line pressure and the flow your application needs, and we will confirm from the datasheet curves that the 200 size at 1/8 in NPT is correctly sized before you order.
The 5 um grade (code W) is the finer of the two catalogue filter options - it captures smaller particles than the standard 40 um element, which matters when feeding valves, cylinders or instruments sensitive to fine contamination. The fitted reverse/check valve (code K) holds downstream pressure if the upstream supply is interrupted. Both are factory build options, so order the exact code you need.
