The AirTAC GFR20008MJC3WTK AirTAC Filter Regulator NPT 1/4 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 PT1/4" 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 GFR20008MJC3WTK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration is the size 200 unit with a 1/4 in NPT port, a fine 5 um filter element (code W), a manual drain on the bowl, a round pressure gauge reading in bar, a built-in reverse/check valve, and no mounting bracket. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the manual-drain bowl keeps the unit simple to service - just open the drain valve periodically to release collected condensate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including 40 um or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. 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. 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.

| 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. |

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 conditioning for a spray booth air drop: the 5 um element strips water and grit before the regulator feeds a steady, controlled pressure to the spray gun, protecting finish quality.
Clean, regulated air for analytical instruments and small test-rig actuators, where the 5 um grade and a stable setpoint matter and the bar-scale round gauge gives a clear local readout.
Feeding vacuum and cylinder circuits on a packaging line: the filter regulator holds consistent pressure to the gripper cylinders while the check valve helps hold the circuit if upstream supply dips.
Start with the port and size: this unit steps down to 1/4 in NPT, so match it to the line size your machine actually uses - moving up to a size 300 or 400 body buys more flow capacity if your demand is higher. Because this code carries the manual drain (M), plan on periodic draining by hand; if nobody is available to do that, a differential-pressure or automatic drain variant is the better fit. The 5 um element (W) suits applications that need cleaner air than the 40 um standard element delivers. The gauge on this unit is a round external type reading in bar; square embedded gauges and MPa or psi scales are available if you prefer. PT is the standard thread for the series, with G (BSPP) and NPT as orderable options - this code specifies NPT. A bracket can be added on variants that include one; this code omits it. Flow for the GFR series is published as curves, not a single rating, so send us your air demand and let us confirm the correct size 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your air demand and line conditions and we will confirm the datasheet curves and check the sizing against your application before you order.
The M in the code specifies a manual drain on the filter bowl: condensate collects in the bowl and someone opens the drain valve to release it. If you cannot rely on regular manual draining, choose a differential-pressure or automatic drain variant instead - both are available in the GFR family in this size.
