The AirTAC GFR20008MJC3WT AirTAC Filter Regulator NPT1/4, 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 PT1/4" 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 GFR20008MJC3WT is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in one body. This configuration is threaded NPT1/4 (1/4 in), carries the finer 5 um filter element (code W, versus the 40 um standard), drains condensate by hand via its manual drain, and is fitted with an external round gauge scaled in bar. The polycarbonate bowl suits the non-freezing -5 to 70 C range, and maximum inlet pressure is 1.0 MPa (145 psi). With a manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT to order), bracket and reverse valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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. |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds clean, regulated air to the small gripper cylinders on a cartoning or case-packing cell, where the 5 um element helps keep fine debris out of close-tolerance components and the round bar gauge lets operators verify the set pressure at a glance.
Sits upstream of the directional control valve manifold on a CNC or special-purpose machine, removing water and particulate that would otherwise stick spools or foul pilot valves, while holding a steady supply pressure for consistent clamping and actuation.
Prepares the air line feeding paint spray guns in a coating or finishing booth, where clean, moisture-free air at a stable set pressure supports consistent finish quality and the manual drain suits a supervised, shift-based operation.
Your choices on this family are decodable from the code. Size 200 with a 1/4 in port suits lighter-duty circuits; step up to 300, 400 or 600 for larger ports and higher flow demand. Drain: manual (as here - you drain the bowl by hand) versus automatic or differential-pressure for hands-off condensate removal. Filter grade: 40 um standard or 5 um (W) for finer protection of downstream valves and cylinders. Gauge: embedded square or external round, scaled in MPa, psi or bar - this unit carries a round gauge in bar. Thread: PT is the standard; G (BSPP) and NPT are order options. Bracket: included by default, omitted with code J (as here).
Flow is published as curves, not a single rated figure, so send us your pressure and flow requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as characteristic curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your working pressure, set pressure and required flow, and we will confirm sizing from the datasheet curves on request before you order.
The M in the code means condensate is drained by hand: someone opens the bowl drain at intervals rather than relying on an automatic or differential-pressure mechanism. It suits supervised cells and intermittent duty. Note that with a manual drain the regulation range is 0.05-0.9 MPa (7-130 psi). If you want hands-off condensate removal, ask about the automatic (A) or differential-pressure (blank) drain versions of the same unit.
