The AirTAC GFR30010JC2 AirTAC Filter Regulator PT3/8, 40 um 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 PT3/8" 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 GFR30010JC2 is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This size-300 unit is supplied with PT3/8 ports, a 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as air passes through, and a round pressure gauge reading in psi. The polycarbonate bowl gives a clear view of the condensate level, the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, an optional 5 um element (code W), automatic or manual drain variants, G (BSPP) or NPT thread options, and a choice of gauge scale. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 feeds the sealing cylinders and glue heads on a carton-sealing line, keeping water and debris out of the directional valves while the 0.15-0.9 MPa adjustment range holds a steady working pressure.
This filter regulator conditions the air supplying gate and stopper cylinders on a bottling conveyor, with the round psi gauge giving operators a visible setpoint at the machine.
Clean, regulated air to the tool-changer and clamping circuits of a CNC machine tool, with 40 um filtration protecting the valves from particulate and the differential drain keeping the bowl clear without daily attention.
Choosing within GFR comes down to a few decodable options. Match the size and port to your circuit: size 300 with PT3/8 suits mid-size air lines, and stepping up a size increases both the port and the flow path. Pick the drain: differential-pressure (this unit) needs no daily attention, automatic drains continuously, and manual puts you in control of emptying. Choose 40 um standard filtration or the finer 5 um W grade, and select the gauge scale in MPa, psi or bar. PT is the standard thread; G (BSPP) and NPT are order options, and a bracket can be added where mounting is needed. 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your air demand and line pressure and we will confirm the sizing from the datasheet on request.
This unit uses a differential-pressure drain, which bleeds condensate from the bowl automatically as the pressure differential across the filter builds - no daily manual draining. If you prefer, GFR variants are available with automatic or manual drains; the drain type is set by the code, and a manual-drain unit also widens the regulator adjustment range down to 0.05 MPa.
