The AirTAC GFR300C15MF2WG AirTAC Filter Regulator G1/2 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 GFR300C15MF2WG is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is built for 1/2 in ports with G (BSPP) thread, carries a 5 um filter element (W grade), a manual-drain polycarbonate bowl, and a standard regulator covering 0.05-0.9 MPa (7-130 psi). An embedded square gauge with a psi scale is fitted, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, manual, automatic or differential-pressure drains, and 40 um or 5 um filter grades. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.15 - 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.

Mounted at the drop feeding a bottling line, it filters water and particles from the plant air and holds a steady regulated pressure to the gripper and pusher cylinders.
Installed ahead of a CNC fixture clamping circuit, it cleans the shop air to 5 um and lets the setter dial in the clamping pressure on the built-in psi gauge.
Fitted at a workshop hose-reel outlet, it lets the technician drain collected water by hand at shift end and supplies regulated air to impact wrenches and tyre chucks.
When choosing within GFR, the size sets the port step and the flow capacity: this unit is size 300 with a 1/2 in G-thread port, while the family steps ports from 1/8 in to 1 in across sizes 200 to 600. The real choices are the drain (manual here, with automatic and differential-pressure available), the filter grade (5 um fitted; 40 um is the standard grade), the gauge (embedded square with psi scale fitted; an external round gauge is optional, with MPa, psi or bar scales), the thread (PT standard, G or NPT to order) and the bracket (included here). Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 one number. Send us your flow and pressure conditions and we will confirm the datasheet figures for this unit on request.
The M in the code sets a manual drain: collected water is released by operating the drain by hand, unlike the automatic or differential-pressure drain options. Manual-drain units carry the wider 0.05-0.9 MPa (7-130 psi) regulation range.
