The AirTAC GFR30010MF1WTK AirTAC Filter Regulator NPT3/8 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 GFR30010MF1WTK is an AirTAC GFR300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain for the polycarbonate bowl, an embedded square gauge scaled in MPa, and a built-in reverse (check) valve that holds downstream pressure when the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT / G / NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge or no gauge, and optional reverse valve. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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.

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |

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 and regulates air to a bench-mounted pneumatic press, with the 5 um element protecting the press valve from fine particulate and the check valve holding set pressure if the shop supply dips.
Installed at the air drop feeding a cartoning or wrapping machine, cleaning condensed water from the supply and holding a steady regulated pressure to the machine's cylinders.
Supplies filtered, regulated air to conveyor divertors, stoppers and gate cylinders, with the manual drain emptied during scheduled line checks and the gauge giving a local pressure readout.
Size 300 with a 3/8 in port suits lines running moderate air demand; step up to size 400 or 600 for higher flow, or down to size 200 for compact circuits - match the size and port to the flow your application needs. The 5 um element (code W) is the right choice where finer particulate removal matters, such as downstream of sensitive valves or instruments; the standard grade is 40 um. The manual drain means an operator opens the bowl drain periodically, which suits installations that are checked routinely; choose automatic or differential-pressure drain where the unit is hard to reach. This unit ships as specified with an embedded square MPa gauge and a reverse (check) valve fitted, and includes a mounting bracket. NPT is the thread for this code; PT and G (BSPP) are order options. Flow 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 GFR300 series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: the polycarbonate bowl is emptied by hand at intervals. If the unit will be mounted where regular access is difficult, the same GFR300 size is available with an automatic drain (code A) or a differential-pressure drain (blank) instead - note the regulation range differs by drain type, and this manual-drain version adjusts from 0.05 to 0.9 MPa (7-130 psi).
