The AirTAC GFR20006MLC3WTK AirTAC Filter Regulator NPT 1/8 in 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 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 GFR series is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is a size 200 GFR with a 1/8 in NPT port, a manual drain, a 5 um filter element (the W grade; 40 um is the family standard) and the low-pressure regulator type. It is fitted with an external round gauge reading in bar, a reverse/check valve and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G (BSPP) or NPT threads, with automatic, manual or differential-pressure drains, 40 um or 5 um elements, and a choice of gauge scales. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding a low-pressure glue or coating manifold on a packaging line: the 5 um element keeps nozzle tips clear of water and particulate while the low-pressure regulator type holds a steady set pressure downstream.
Supplying a laboratory test bench or pilot rig: the round bar gauge gives a direct local pressure readout at the bench, and the manual drain suits intermittent, attended use where an operator drains the bowl at shutdown.
Air preparation for pneumatic clamps on a machining fixture: filtered, regulated air to the clamp cylinders, with the reverse/check valve already fitted in the supply path and the bracket allowing panel or frame mounting.
The real choices within GFR are: size and port (200 through 600, 1/8 in to 1 in) stepped against the flow your line needs; drain type (manual, automatic or differential-pressure); filter grade (40 um standard, or 5 um with the W code); gauge scale (MPa, psi or bar) and round versus embedded square gauge; thread (PT is the standard, G or NPT to order); and whether a bracket is included. This code fixes those choices at 1/8 in NPT, manual drain, 5 um, low-pressure type, round bar gauge and bracket included. The L code marks the low-pressure regulator type; its exact adjustment range is not published in our data, so confirm it with us if your set pressure is critical. Because catalogue flow is given as curves, not a single rating, ask us to check the curve against your application 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 G-series flow as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM here. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
M is the manual-drain code: the bowl is drained by hand, which suits intermittent or attended installations. The GFR family also offers automatic and differential-pressure drains. On this unit the manual drain is paired with the 5 um W-grade element and the low-pressure regulator type.
