The AirTAC GFR30010MF2W AirTAC Filter Regulator PT3/8 5 um Manual Drain 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 GFR30010MF2W is a size 300 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries PT3/8 ports, a manual drain on the polycarbonate bowl, 5 um filtration element, an embedded square gauge with psi scale, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard 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 GFR300 series is one size within the GFR line, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge styles and scales, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so 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.

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.

Installed ahead of solenoid valves and air bearings on a CNC cell, this filter regulator strips water and fine particles from the shop air and holds a steady set pressure so tool-change cylinders and clamps act consistently through the shift.
On a carton packaging line, the unit feeds pneumatic diverters, pushers and heat-seal cylinders with filtered air at a regulated pressure, and the manual drain lets an operator clear accumulated condensate during scheduled changeovers.
At a bench-mounted assembly station with air screwdrivers and pneumatic presses, the 5 um element protects sensitive tooling from particulate while the psi-scaled square gauge gives the technician a direct readout when setting working pressure.
Size 300 with PT3/8 ports suits lines running moderate air consumption; step up to size 400 or 600, or down to size 200, when the port or flow path needs to change - we can check the flow curves against your demand before you order. The manual drain on this unit means an operator opens the drain periodically to discharge collected condensate; choose the automatic drain variant if the unit is mounted where regular access is impractical, or the differential-pressure drain as the default. The 5 um element (code W) is finer than the 40 um standard and suits downstream components that need cleaner air. The embedded square gauge reads in psi; MPa and bar scales and an external round gauge are available. PT thread is the standard here, with G and NPT offered as order options, and the bracket is included.
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 curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow figures from the datasheet so you can size the unit correctly before ordering.
The M in the code specifies a manual drain: an operator opens it periodically to discharge water collected in the polycarbonate bowl. It suits units mounted where regular access is easy. If the unit will sit in a hard-to-reach position, ask about the automatic or differential-pressure drain variants instead.
