Airtac GFR Filter Regulator GFR400C15MJN
The AirTAC GFR Filter Regulator GFR400C15MJN 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.

About the Airtac GFR Filter Regulator GFR400C15MJN
The AirTAC GFR400C15MJN is a filter regulator: filtration and pressure regulation combined in one body, with a drain bowl and no lubricator. This 400-size unit has a PT1/2 port, a manual drain, the standard 40 um filter element, and the N code means no gauge is fitted. With a manual drain, the regulated outlet is adjusted across 0.05-0.9 MPa (7-130 psi), and maximum working pressure is 1.0 MPa (145 psi). Medium is compressed air only, with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series, which covers 200, 300, 400 and 600 sizes and offers drain type, filter grade, gauge and thread options. Because flow is published as curves rather than a single rating, we confirm datasheet and flow figures 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.

Where the Airtac GFR Filter Regulator GFR400C15MJN Is Used
Machine build OEM air drop
Built into new machine frames as the set-pressure point for actuator circuits, where the builder's own HMI or panel gauge displays pressure, so no local gauge is needed on the unit.
Pneumatic press hold-down circuit
Sets hold-down pressure on a small pneumatic press or clinching station, with the manual drain emptied during scheduled maintenance rounds.
Control cabinet air feed
Mounted inside a control cabinet to feed pilot-air circuits of directional valves, with pressure read on the cabinet's existing instrumentation.
Is the Airtac GFR Filter Regulator GFR400C15MJN the Right Unit?
Choose the N (no gauge) variant when a panel-mounted or remote gauge already shows the downstream pressure, keeping the unit compact and the cost down; gauge-equipped variants (square embedded, or external round in MPa, psi or bar scales) are available in the same series. This 400 size has a 1/2 in PT port, with G (BSPP) and NPT threads orderable instead. Manual drain suits periodically attended installations, while automatic and differential-pressure drains serve unattended duty. The 40 um element is standard; the W code gives 5 um. J means no bracket is supplied.
Flow for the G-series is published as curves, not a single rating, so ask us to confirm sizing before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR Filter Regulator GFR400C15MJN FAQ
We do not quote a rated flow figure because AirTAC publishes G-series flow as performance curves rather than a single rating. Send us your inlet pressure and required flow and we will confirm the datasheet and whether the 400 size is right for your application on request.
The N code means no gauge is fitted to this unit. If you need local pressure indication, order a GFR400 variant with the gauge code: a square embedded gauge (scales MPa, psi or bar) or an external round gauge, all as catalogue options in the same series.
