The AirTAC GFR300C10MJC2WTK AirTAC Filter Regulator NPT3/8 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 GFR300C10MJC2WTK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is size 300 with a 3/8 in NPT port, carries the 5 um filter element (the finer of the two grades), uses a manual drain on the bowl, and includes a round pressure gauge reading in psi. A reverse (check) valve is fitted, and the regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowl on the 300 size is polycarbonate (PC), and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with the W code), gauge style and scale, G (BSPP) and NPT thread variants, bracket choice and a reverse valve. Flow for these units is published as curves rather than a single rated figure, so ask us to 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.

Filtered, regulated air for machine-tool clamps, tool-changer cylinders and part-blow nozzles at the cell, with the 5 um element catching fine particulate before it reaches the machine valves.
Regulated supply for stopper cylinders, pushers and grippers along a bottling or packaging conveyor, with the manual drain bled as part of the shift checklist.
Clean, regulated air for sample-handling valves and small actuators on an automated lab bench, where the round psi gauge gives operators a local setpoint readout.
Match the size and port to the air demand of the circuit: this unit is size 300 with a 3/8 in NPT port, and larger sizes carry larger ports and more flow. Drain type is a real choice - differential-pressure (the default), automatic, or manual as on this code; manual drain suits points that are bled during routine checks. Filter grade is 40 um standard or 5 um with the W code, as fitted here. Gauges are the embedded square type or an optional external round gauge, scaled in MPa, psi or bar - this code carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and brackets are optional (not included on this code).
Flow for G-series units 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 here. Tell us your required flow and working pressure and we will confirm the datasheet figures and check the sizing against your application on request.
This code uses a manual drain: the bowl is bled by hand at intervals. It suits point-of-use installations that are attended during routine checks. If the unit sits where it cannot be visited regularly, the differential-pressure drain (the default) or the automatic drain option is the better decode - ask us and we will confirm the right variant for your setup.
