The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 in NPT 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 PT1/4" 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and sets a stable downstream pressure in one compact body. This 200-size unit is threaded 1/4 in NPT, carries the standard 40 um filter element, and uses a manual drain, so the bowl should be drained by hand as part of routine checks. It is supplied without a pressure gauge and without a mounting bracket, and a reverse (check) valve is fitted to prevent backflow through the unit.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge options and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Point-of-use filtered and regulated air for a CNC machine's pneumatic clamps and tool-changer cylinder. The manual-drain bowl suits a drop that is bled during daily shift checks, and the check valve keeps the setting from being disturbed by backflow.
Supplies clean, regulated air to the sealing-head and flap-folding cylinders of a carton sealing machine. The 40 um element catches pipe scale and moisture that would otherwise score the sealer's valve spools.
A regulated air outlet on a maintenance bench for testing air cylinders, actuators and small pneumatic tools at a set pressure. The 1/4 in NPT port matches standard bench fittings, and the check valve holds the downstream circuit if upstream supply is interrupted.
GFR200-08 is the 200-size, 1/4 in NPT entry in the GFR range; step up to 300, 400 or 600 when your line needs a larger port and more flow. The 40 um element is the standard grade for general plant air; choose the W variant (5 um) where finer protection matters. Drain choice matters in practice: manual drain (this code) means an operator drains the bowl, while automatic and differential-pressure drains discharge condensate without hands-on attention. This unit has no gauge fitted (code N) and no bracket (code J); gauge and bracket options exist elsewhere in the series, and PT is the standard thread with G and NPT as orderable variants - here NPT is specified. Flow for this series is published as curves, not a single rating, so 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 flow for the GFR series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your application and we will confirm the flow data from the datasheet so you can size the unit correctly before ordering.
No. The N in GFR20008MJNTK means no gauge is fitted. Gauge options are available in the GFR series, including embedded square gauges and external round gauges with MPa, psi or bar scales, so a different code can be ordered if you want a gauge included.
