The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010JN) 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 GFR40010JN is a G-series filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 configuration has a PT 3/8 in port, the standard 40 um filter element, a differential-pressure drain in the polycarbonate bowl, and no pressure gauge (code N). The J code means it ships without a mounting bracket, keeping the footprint minimal where an existing panel already carries the instrumentation.
It is a genuine AirTAC part from the G series, offered in sizes 200, 300, 400 and 600 with 1/8 in to 1 in ports and PT, G (BSPP) or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator covers 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain, and the temperature range is -5 to 70 C. Flow figures are published as curves rather than a single rating; ask us and we will confirm the flow and datasheet values 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Filters and regulates the air feeding conveyor stop-gates, pushers and carton-forming cylinders on a packaging line, where general-grade 40 um filtration is sufficient.
Installed at the air drop point of an assembly workstation to give operators a set, stable working pressure for air tools and clamping fixtures.
Used where a pre-assembled control panel already has its own gauges, so the filter regulator is specified without one to avoid duplicate instrumentation.
Choose size 400 with its 3/8 in port when your air demand exceeds what a size 300 unit serves comfortably, or drop to size 200/300 for lighter circuits. The standard 40 um element suits general plant air; specify the W suffix for a 5 um element where cleaner air is required. This version carries no gauge, so add an external round gauge in MPa, psi or bar scale from the catalogue options if local pressure indication is needed. PT is the standard thread, with G and NPT variants available to order, and a bracket can be added if you need panel mounting.
AirTAC does not publish a single rated flow figure for this family, only curves. Contact us with your application details and we will confirm sizing from 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 GFR400 series as curves rather than a single rated number, so we do not state one here. Give us your supply pressure and required air demand and we will confirm the flow and datasheet figures for this model on request.
Yes. The N in this code simply means no gauge is fitted; catalogue options include an external round gauge with MPa, psi or bar scale. For finer air, the W suffix selects a 5 um element instead of the standard 40 um grade fitted here.
