The AirTAC GFR300C10MJC2 AirTAC Filter Regulator 3/8 in PT 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 GFR300C10MJC2 is a 300-size filter regulator that cleans compressed air and sets downstream pressure in a single body. Water and particulate are removed by the 40 um filter element into the polycarbonate bowl, which is emptied by hand via the manual drain, while the standard regulator holds your set pressure between 0.05 and 0.9 MPa (7-130 psi). The fitted external round gauge reads in psi, so operators can check and adjust the setting at a glance. Porting is 3/8 in PT thread, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part from the G-series filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G (BSPP) or NPT threads. Drain, filter grade, gauge style and scale, bracket and reverse-valve options let you match the unit to the installation. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing 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 pneumatic press or clamping station, the unit strips water and chips from the shop air and holds a steady regulated pressure so stroke force stays repeatable from cycle to cycle.
On a packaging or case-sealing line, the filter regulator conditions the air feeding cylinders and diverters, with the round psi gauge letting technicians verify the set point during changeover.
Mounted at the supply point for air-operated control valves or actuators, it removes moisture that would foul internals and regulates supply pressure to the value the actuator positioner expects.
Start with the port step: this unit is 3/8 in PT on the 300-size body, so check it against your line size and the flow curve before ordering - if your demand sits near the top of the curve, stepping up to the 400 size may be the better choice. Drain type is a real decision: the manual drain here suits installations where an operator can bleed the bowl on a routine, while automatic or differential-pressure drains suit unattended positions. The 40 um element is the standard grade; specify code W for 5 um where finer filtration is needed. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket choice are also selectable.
Because AirTAC publishes flow as curves and not a single rated figure, ask us to confirm sizing against your application 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 this series as curves rather than a single rated figure, so no single number would be honest. Send us your application details and we will confirm the flow curve and datasheet figures for the GFR300 at 3/8 in before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is emptied by hand. Choose manual where the unit is accessible and checked on a routine; choose an automatic or differential-pressure drain version where the installation is unattended. Note that with a manual drain the regulation range is 0.05-0.9 MPa (7-130 psi).
