The AirTAC GFR200-06 NPT1/8 AirTAC Filter Regulator, 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 PT1/8" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 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 configuration is the 200 size with a 1/8 in NPT port, the low-pressure regulator type, a manual drain on the polycarbonate bowl, a 40 um standard filter element, an embedded square gauge with psi scale, and a reverse (check) valve fitted. The manual drain means the bowl is emptied by opening its drain valve by hand as part of routine maintenance, and the check valve holds the downstream circuit if upstream supply is interrupted.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (manual, automatic or differential-pressure), a 5 um element option, gauge scale options and G/NPT thread variants. Flow is published as curves rather than a single rating, so we confirm the exact flow and datasheet figures 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. 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.

|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

A low-pressure filter regulator feeding clamp cylinders on a fixture line: filtered air, a stable reduced pressure set by the psi gauge, and a check valve that holds the clamp circuit if the upstream supply drops.
A 1/8 in NPT take-off branch feeding sensors, small actuators or a control panel on a packaging machine, where the low-pressure type regulator keeps the branch below main-line pressure and the manual drain is emptied during scheduled changeover.
Instrument air for laboratory rigs and pilot-scale test benches: the 40 um element protects sensitive downstream devices, the square psi gauge gives a clear local reading, and the compact 200 frame mounts on the included bracket at the bench.
Start with size and port: 200 is the smallest GFR frame, and the 06 port is 1/8 in NPT - step up to 300/400/600 and larger ports when the circuit carries more air. This unit is the low-pressure (L) type, so use it where the working pressure sits below what a standard regulator targets; its exact adjustment range is not published in the standard tables, so ask us to confirm it against your setpoint before ordering. Choose the drain to suit access: manual (this unit) suits attended installations, automatic suits unattended duty, and differential-pressure is the default. The 40 um element is standard; specify the W code for 5 um where finer filtration is needed. Gauge scale is psi here (MPa and bar scales exist), and the reverse/check valve is already fitted. Thread is NPT as ordered; PT is the catalogue standard and G (BSPP) is also available. A mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, so send us your air demand and line conditions and we will confirm sizing from 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 GFR flow as curves across the pressure range rather than a single rated number, so we do not quote one figure. Send us your air demand and upstream pressure and we will confirm the sizing from the datasheet on request before you order.
The M in this code means the polycarbonate bowl is drained by hand: open the drain valve periodically to expel collected water. If the unit will sit in an unattended location, the automatic drain (code A) or the differential-pressure drain (the default, blank code) removes that routine task - both are orderable variants of the same GFR200 unit.
