The AirTAC GFR300C15MJF2T AirTAC Filter Regulator NPT1/2 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 GFR300C15MJF2T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 1/2 in NPT ports, a manual drain under the polycarbonate bowl, the standard 40 um filter element, an embedded square gauge reading in psi, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). No reverse/check valve is fitted and no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 port sizes from 1/8 to 1 in, and with choices of drain type, 40 or 5 um filtration, gauge scale, thread (PT standard, G and NPT as order options), bracket and check valve. Flow for the GFR300 is published as curves rather than a single rating; ask us and we will 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.

Installed ahead of a CNC machine tool's air inlet, this unit strips water and swarf-laden particulate from the shop supply and holds a set pressure for tool-change cylinders and clamping actuators, with the psi gauge giving the operator a visible setpoint.
Mounted at the air inlet of a carton-forming or case-sealing packaging machine, it cleans the supply and regulates pressure to the machine's diverters and pusher cylinders, while the manual drain lets maintenance purge accumulated condensate during scheduled rounds.
Fitted on individual air drops around a plant, it gives each workstation its own filtered, regulated supply for air cylinders, air guns and pneumatic fixtures, so one department's pressure setting does not depend on the main line regulator.
Size 300 with 1/2 in NPT ports sits in the middle of the G-series flow ladder (200/300/400/600); step up or down a size when the application's air demand changes. The M in this code specifies a manual drain, so the bowl is purged by hand at intervals; automatic (A) and differential-pressure (blank) drain versions of the same size can be ordered if the unit will not be checked regularly. The 40 um element is the standard grade - add W to the code for the 5 um element where finer particulate protection is needed. The square gauge on this unit reads in psi; MPa and bar scales are alternative codes and an external round gauge is optional. Thread here is NPT, with PT as the standard and G as the other order option, and J means no mounting bracket is supplied. 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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number on the page. Send us your required flow and working pressure and we will confirm the datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: the bowl is emptied by operating the drain valve at intervals. If the installation will not be checked regularly, the same GFR300 size can be ordered with an automatic drain (code A) or a differential-pressure drain (blank) instead.
