The AirTAC GFR300C10JC3T AirTAC Filter Regulator NPT3/8, Bar Gauge 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 GFR300C10JC3T is a size-300 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one compact body. This configuration carries a 3/8 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the bowl is high enough. The regulator is the standard type with a setting range of 0.15-0.9 MPa (20-130 psi), and this unit is fitted with an external round gauge reading in bar. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the polycarbonate bowl suits general indoor plant air. No mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, G/NPT thread variants, manual or automatic drains, a 5 um (code W) filter element, gauge scale choices and bracket options, so you can match the unit to your line. Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet figures for your application before you order.

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 and regulated air for the clamping and pressing cylinders on a small stamping or assembly press, with the bar gauge giving the setter a clear local pressure reading.
Conditioning the air feed to diverters, pushers and stopper cylinders on a carton packaging conveyor, where the 40 um element protects valves from water and debris.
Point-of-use filter regulation ahead of gripper and pick-and-place actuators on an automation cell, keeping supply pressure stable as the cell cycles.
Start with the port step: this unit is 3/8 in NPT in size 300; step up to 400 or 600 if your air demand outgrows it, or down to 200 for lighter lines. Drain choice matters: the differential-pressure drain here needs no attention day to day, but a manual drain (code M) suits low-flow duty and an automatic drain (code A) suits unattended installations. The 40 um element is the standard grade; specify the 5 um W option where finer protection is needed. Gauge scale can be ordered in MPa, psi or bar - this unit reads bar on an external round gauge. Thread is NPT here; G (BSPP) is the other order option, with PT as the catalogue standard. A bracket can be added where the unit needs panel fixing (this configuration ships without one). Flow is published as curves, not a single rating, so send us your air demand 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 this series as curves, not as a single rated figure, so there is no one number we can quote honestly. Send us your air demand and operating pressure and we will confirm the datasheet curve figures for this 3/8 in size-300 unit before you order.
This configuration is fitted with an external round gauge reading in bar. The GFR series normally carries an embedded square gauge, and gauges can be ordered with MPa, psi or bar scales, so you can match the scale to the rest of your plant if you prefer.
