The AirTAC GFR400-10JF2T AirTAC Filter Regulator NPT3/8 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 GFR400-10JF2T is a filter regulator: water and particulate removal plus downstream pressure regulation combined in a single body. This size 400 unit carries a 3/8 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The square pressure gauge is fitted and reads in psi, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and no check valve is fitted. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this 400 size is PC (polycarbonate), and the J code means no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and thread options PT, G (BSPP) and NPT. Across the series you can order automatic or manual drains, a 5 um (W) filter element, different gauge scales, and a bracket where needed. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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 and regulated air feeding a pneumatic stamping or clinching press, where the 3/8 in port suits the main drop and the square psi gauge lets operators set and verify working pressure at the cell.
Air preparation for carton-sealing and case-packing machines, where the 40 um element protects directional valves and cylinders from water and debris and the regulator holds a stable setting through shift-long cycling.
Supply point for air-operated quarter-turn valves on a process skid, where the combined filter regulator in one body saves panel space and the differential-pressure drain keeps condensate out of the actuator supply.
Start with the port step: size 400 with a 3/8 in NPT port sits in the middle of the GFR range, so step up to 600 or down to 300/200 depending on the pipe size and the air demand of the circuit. Choose the drain next: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) drains are order options. The 40 um element fitted here is the standard grade; specify W for the 5 um element if finer filtration is needed. The square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread is NPT here because the code ends in T; PT is the standard and G (BSPP) is also orderable. J means no bracket, so add a bracket variant if the unit will be panel or wall mounted. Because flow for this series is published as curves and not as a single rated figure, send us your application details 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 the GFR series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure, set pressure and required air consumption, and we will confirm the flow data from the datasheet for this exact model on request.
This GFR400-10JF2T uses the differential-pressure drain, the default option: condensate is discharged automatically when the pressure differential across the filter element rises high enough. If you prefer a drain that empties on a timer-free automatic basis or one you operate by hand during maintenance, the A (automatic) and M (manual) drain variants of the same size are available to order.
