The AirTAC GFR400C10JF1T AirTAC Filter Regulator NPT 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 AirTAC GFR400C10JF1T is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one 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 self-drains as flow passes through. Outlet pressure is set with the fitted embedded square gauge, scaled in MPa, and the standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type. 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, no mounting bracket is fitted, and no reverse/check valve is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), optional external round gauges in MPa, psi or bar scales, and G or NPT threads as order options alongside the PT standard. Rated flow for GFR units is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application.

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.

Clean, regulated air feeding tool-change cylinders and clamping fixtures on a machining centre, where the 40 um element keeps swarf-contaminated shop air out of the valves and the square MPa gauge lets setters verify clamp pressure at a glance.
Pressure regulation and water removal for the pneumatic cylinders that drive carton forming, sealing and pusher stations on a packaging conveyor, with the differential-pressure drain clearing condensate through each production shift without operator attention.
A filtered, regulated air drop serving hand tools, grippers and air tables at an assembly cell, where the 3/8 in NPT connection ties straight into standard NPT piping and the regulator holds a steady working pressure for consistent tool performance.
Size 400 with a 3/8 in NPT port sits in the upper-middle of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs, and match the thread to your piping (PT is the catalogue standard, with G and NPT as order options). This unit pairs the standard 40 um element with a differential-pressure drain, which suits general plant air; choose the 5 um W element where downstream equipment needs finer filtration, or an automatic drain for unattended condensate removal. The fitted square MPa gauge covers standard setting work; an external round gauge in psi or bar scale can be ordered if your team reads in those units. No bracket is fitted on this code, so plan your mounting accordingly.
Because AirTAC publishes flow for GFR units as curves rather than a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 GFR filter regulators as curves, not as a single rated figure, so we do not quote a flow number for this unit. Tell us your application and required flow and we will confirm the datasheet curve and check the sizing with you before you order.
This code has no drain letter, so it carries the differential-pressure drain: condensate in the bowl is discharged automatically as air flows through the unit, with no operator action needed. It is one of three catalogue drain choices for GFR units, alongside automatic (code A) and manual (code M), and the drain type also affects the regulator setting range: 0.15-0.9 MPa (20-130 psi) with the differential-pressure or automatic drain fitted.
