The AirTAC GFR400C10JC2G AirTAC Filter Regulator G3/8 (3/8 in) 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 GFR400C10JC2G is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 400 unit is configured with a G3/8 (3/8 in) port and G (BSPP) thread, a 40 um standard filter element, a differential-pressure drain, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this size 400 unit is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the family include a 5 um element (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, PT or NPT threads, and bracket choices. Flow figures are published as curves rather than a single rating, 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.

Point-of-use conditioning on a machining centre drop that feeds pneumatic clamps and tool-change actuators: the 40 um element strips water and swarf-laden condensate before it reaches the spools, while the regulator holds a steady setting for repeatable clamping.
Supply conditioning for carton sealers and case packers, where sealing jaws, cylinders and vacuum generators need clean air at a fixed pressure. The round psi gauge lets line staff verify the setting at a glance during changeover.
Feeding spray guns and air-assisted applicators in a finishing booth, where moisture in the air line causes fisheyes and pressure drift ruins fan pattern. This unit filters and regulates the booth air supply at the wall drop.
Match the size and port to the air demand of the circuit: this unit is size 400 with a G3/8 port, and larger sizes in the family carry larger ports and more flow capacity, though flow is published as curves rather than a single rating. Drain type is a real choice: differential-pressure (this unit) is the default, with automatic (code A) and manual (code M) available. The 40 um element is standard; specify the W code for 5 um filtration. Gauge options are an embedded square gauge or an external round gauge with MPa, psi or bar scales; this configuration carries a round psi gauge. Thread here is G (BSPP), with PT as the standard and NPT orderable; brackets are optional and this unit is configured without one. Ask us to confirm sizing against your application before ordering.
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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your air demand and working pressure and we will confirm the flow and datasheet figures for this exact configuration on request.
The differential-pressure drain is the default drain option on this unit and handles condensate without operator action under normal running conditions. The GFR family also offers an automatic drain (code A) and a manual drain (code M) if your maintenance routine suits those better. For this configuration the regulation range is 0.15-0.9 MPa (20-130 psi).
