The AirTAC GFR400C10JF2T AirTAC Filter Regulator, NPT3/8, Square 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 GFR400C10JF2T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded NPT 3/8 in, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl purges automatically as flow passes through - no daily manual draining. The fitted square gauge reads in psi, and 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 polycarbonate bowl suits the 400 size, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, a choice of 40 um or 5 um (code W) filtration, differential-pressure, automatic or manual drains, psi, MPa or bar gauge scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

On a beverage bottling line, clean dry air at a stable setpoint drives the gripper and clamp cylinders that handle bottles between filler and capper. A filter regulator at each drop removes condensate and particulate and holds the working pressure steady so gripper timing does not drift through a shift.
CNC machining centres and lathes use regulated air for tool-change actuators, chuck clamping and chip-clearing blasts. Feeding those circuits through a filter regulator keeps swarf and water out of the machine's directional valves while holding the clamping pressure the tooling was set up for.
On packaging and palletising conveyors, air jets clear dust from film and web while diverter gates and stopper cylinders sequence packs. A filter regulator on the supply leg protects those small valves from moisture carryover and lets the line set the exact jet pressure the product needs.
Size 400 with a 3/8 in port sits in the middle of the GFR range: step up to 600 or down to 300/200 depending on the air demand of the circuit, since port size and body size move together. Drain choice matters in practice: the differential-pressure drain on this code purges with flow, while automatic (code A) drains regardless of flow and manual (code M) requires operator action - pick based on whether the line runs continuously. If finer filtration is needed downstream of sensitive valves, the 5 um element (code W) is the alternative to the standard 40 um. The square gauge here reads psi; MPa and bar scales are also available, and an external round gauge is an option. NPT is specified on this code; PT and G threads are order options, and brackets can be added on codes that carry them.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application's air demand and we will confirm the correct size 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 family as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application's air demand and operating pressure and we will confirm the correct size against the datasheet on request before you order.
This code has no drain letter, which means the differential-pressure drain: condensate collected in the bowl is purged automatically whenever air flows through the unit, with no operator action. If the line runs intermittently and needs positive draining regardless of flow, choose automatic drain (code A); if you prefer a manual valve an operator opens during checks, choose code M. All three are catalogue options on this family.
