The AirTAC GFR40010MJF2T 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR40010MJF2T is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is a size 400 unit with a 3/8 in NPT thread, a manual drain bowl in polycarbonate, a 40 um standard filter element, and an embedded square gauge scaled in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with manual drain, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing). No mounting bracket is included in this version (code J), and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drain, a 5 um optional element (code W), gauge scale options, and G (BSPP) or NPT threads as order variants. Flow figures for this series are published as curves rather than a single rating, so contact us and we will 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 0.05 - 0.9 MPa (7 - 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Installed at the point of use on a bottling or carton-packing line, this filter regulator cleans the shop air of water and scale and holds a steady set pressure to the line's actuators, with the psi gauge giving operators a local reading.
Mounted ahead of the solenoid valves on a conveyor or sorting system, the unit protects directional valves from condensate and particles while regulating supply pressure to the cylinders that index and divert product.
Used on the compressed-air feed to laboratory automation equipment such as plate handlers or analytical instruments, where the 40 um element and regulated pressure keep sensitive pneumatic components supplied with clean, stable air.
Size 400 with a 3/8 in 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 - we will check the published flow curves against your demand before you order. The manual drain on this unit means an operator opens the bowl drain periodically, which suits attended installations; choose automatic or differential-pressure drain codes if the unit will be left unattended. The 40 um element is the standard grade for general plant air; specify the W code for a 5 um element where finer filtration is required. The square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is an option. Thread is NPT on this model; G (BSPP) is the other order option, with PT as the series standard. If you need a mounting bracket, order the version without the J code. Because flow is published as curves and not a single rating, 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 GFR series as curves, not as a single rated figure, so we do not quote a number. Contact us with your required flow and working pressure and we will confirm the datasheet curve and check the size 400, 3/8 in unit against your application before you order.
The M in GFR40010MJF2T is the manual drain code: an operator opens the bowl drain to expel collected condensate, which suits installations that are checked regularly. The GFR family also offers automatic drain (code A) and differential-pressure drain (blank, the default) for unattended operation - ask us for those variants.
