The AirTAC GFR300C08MF2T AirTAC Filter Regulator NPT1/4 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR300C08MF2T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 300 unit is threaded NPT1/4, carries a manual drain on its polycarbonate bowl, uses the standard 40 um filter element, and has a standard regulator with a 0.05-0.9 MPa (7-130 psi) setting range. The embedded square gauge reads in psi, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 0.15 - 0.9 MPa (20 - 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.

| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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 a bench-mounted pneumatic press on an assembly line: the 40 um element strips water and swarf from the shop air before it reaches the valve, and the regulator holds a steady set pressure so cylinder force stays repeatable from stroke to stroke.
Supplying air to carton-sealers and diverters on a packaging conveyor: clean, regulated air keeps the small cylinders and air jets on the line behaving consistently through a shift, and the manual drain lets an operator clear condensate at the start of each day.
Conditioning the air feed to a robot gripper circuit: the filter stage protects the gripper valve from moisture and particles, the regulator pins supply pressure for gentle, repeatable part handling, and the psi gauge gives the technician a visible setpoint at the cell.
Size and port set the air capacity: the GFR300 steps up from the compact 200 series and takes NPT1/4 piping here, so match the port step to the line feeding your downstream equipment. This unit is ordered with a manual drain, which you open by hand to release collected water; choose the automatic (A) or differential-pressure (blank) drain variant of the same size if the unit sits where manual draining is impractical. The 40 um element is the standard grade - specify W for 5 um where finer filtration is needed. The square gauge reads in psi, with MPa and bar scales as alternatives and an external round gauge optional. PT is the standard thread; G and NPT are order options, as NPT is here. A bracket is included.
Flow for the GFR series is published as curves, not a single rated figure, so send us your flow requirement and we will confirm sizing against the datasheet before you order.
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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code means the bowl drains by hand: open it periodically to release collected water. If the unit will be mounted where it cannot easily be reached, order the automatic (A) or differential-pressure (blank) drain variant of the same size instead.
