The AirTAC GFR300C08MF2G AirTAC Filter Regulator G1/4 40 um 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 GFR300C08MF2G is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G1/4 (BSPP) port, a 40 um standard filter element, a manual drain bowl and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit is supplied with a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type (differential-pressure default, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar) and thread (PT standard; G and NPT as order options). Flow is published as curves rather than a single rated figure, so ask us to 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 0.15 - 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.

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.

Filtering and regulating the air feeding tool-clamp and actuator circuits on a CNC machining centre, with the square psi gauge giving the operator a direct setpoint readout at the machine.
Conditioning air for gripper and clamp cylinders on a packaging conveyor line, where the 40 um element keeps debris out of directional valves and the regulator holds a steady working pressure.
Air preparation at the point of use on textile weaving machines, combining water and particle removal with pressure regulation in one body to save panel space in crowded pneumatic cabinets.
Choose the size by the port and flow your circuit needs: size 300 with a 1/4 in port suits compact circuits, while sizes 400 and 600 carry larger ports and more flow. Pick the drain to match maintenance: manual drain (this model) is emptied by hand, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard; specify code W for 5 um when finer filtration matters. Gauge scale is selectable (MPa, psi or bar), thread is PT as standard with G and NPT as order options, and a bracket is included unless code J is specified. Because flow is published as curves rather than 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. 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, 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 and datasheet figures for this exact model on request.
The M in the code sets a manual drain: the bowl is emptied by hand during maintenance instead of draining automatically. Choose manual where the unit is easily accessible and drained on a routine; choose automatic or the differential-pressure default where the unit is hard to reach. The manual-drain version also carries the widest regulation range, 0.05-0.9 MPa (7-130 psi).
