The AirTAC GFR30010MC2WK AirTAC Filter Regulator PT3/8 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 PT3/8" 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 GFR30010MC2WK is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is a PT3/8 (3/8 in) unit with a manual drain on the bowl, a fine 5 um filter element (the W grade, tighter than the 40 um standard), a round external gauge reading in psi, and a reverse/check valve fitted to hold downstream pressure. The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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. |
| 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. |

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 clean, regulated air to the cylinders and grippers on a carton-forming packaging line, where the 5 um element protects tight valve clearances and the check valve holds set pressure if the supply dips.
Regulating supply pressure to pneumatic conveyor gate and diverter actuators, with the manual drain serviced during shift checks at an accessible mounting point using the included bracket.
Supplying stable, finely filtered air to bench-top test rigs and analytical instruments, where the psi round gauge lets technicians read and verify setpoints directly.
Work through the decodable choices in order. Size 300 with PT3/8 ports is the middle step of the range (200/300/400/600), so step up or down according to the flow your line needs - we can check the published flow curves against your demand. The 5 um element (code W) suits applications needing finer particulate removal than the 40 um standard; both grades are available across the family. Manual drain means someone opens the drain periodically, which suits accessible installations; automatic or differential-pressure drains suit unattended ones. The round psi gauge is one option alongside the embedded square gauge and MPa/bar scales. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is included here, and the J code omits it.
Because flow is published as curves and not a single rating, 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 we do not quote a number. Tell us your line's air demand and we will confirm from the datasheet curves whether this 300-size PT3/8 unit is correctly sized before you order.
The manual drain (code M) means condensate is released by opening the drain by hand, which suits installations that are easily reached on a maintenance round; automatic and differential-pressure drains are available on the family for unattended points. The 5 um element (code W) is a finer grade than the 40 um standard, removing smaller particulate from the air stream.
