The AirTAC GFR20008MC2WTK AirTAC Filter Regulator NPT1/4 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 AirTAC GFR20008MC2WTK is a size 200 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a 1/4 in NPT port, a fine 5 um filter element, a manual drain for emptying the polycarbonate bowl, a round pressure gauge reading in psi, and a built-in reverse (check) valve that holds the downstream setting if upstream supply is interrupted. Max inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the unit operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um standard or 5 um fine filtration, gauge style and scale options, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm the 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. 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.

|---|---|
| 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. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Clean, regulated air to a small pneumatic press or clamping fixture, with the 5 um element protecting the directional valve and the check valve holding clamp pressure during supply dips.
A dedicated 1/4 in supply drop on a packaging or labelling line, where the manual drain is emptied at shift start and the psi gauge gives the operator a visible setpoint.
Regulated air to robotic pick-and-place grippers and small actuators, where fine filtration keeps pilot valves seating cleanly and the check valve guards against pressure loss mid-cycle.
Size 200 with a 1/4 in NPT port suits compact branch lines and individual machine drops; step up to 300/400/600 when the circuit demands more flow capacity. The 5 um element (code W) is the right pick when downstream valves, cylinders or instruments need finer protection than the 40 um standard element. Manual drain means an operator opens the bowl drain during checks - choose automatic or differential-pressure drain where the unit is hard to reach. The round psi gauge suits US practice; square gauges and MPa or bar scales are also available. The fitted check valve (K) preserves the regulated output if supply pressure drops. PT is the standard thread; G and NPT are catalogue options ordered by code. 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, not as a single rated figure, so no one number is quoted here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: the polycarbonate bowl is emptied by hand, which suits accessible mounting points on a regular maintenance route. If the unit will sit in a hard-to-reach spot, order the automatic (A) or differential-pressure (blank) drain variant of the same GFR200-08 size instead.
