Airtac GFR Filter Regulator GFR400C15MJNW
The AirTAC GFR Filter Regulator GFR400C15MJNW 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 GFR400C15MJNW
The GFR400C15MJNW is an AirTAC GFR400 filter regulator: a filter and a pressure regulator combined in one body with a single polycarbonate drain bowl. It is sized for 1/2in PT ports, and the M suffix specifies manual drainage, so the bowl is drained by hand as part of routine maintenance. The W suffix fits the 5 um filter element instead of the 40 um standard grade, the N suffix means no gauge is fitted, and the J suffix means no mounting bracket is included. Regulating range with manual drainage is 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi); working temperature is -5 to 70 C.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with ports from 1/8in to 1in, and this 400 frame can also be ordered with automatic or differential-pressure drainage, the 40 um element, a gauge, a mounting bracket, G (BSPP) or NPT threads, and a check valve. Flow for the series is published as performance curves rather than a single rated figure, 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.

Where the Airtac GFR Filter Regulator GFR400C15MJNW Is Used
Pneumatic stamping press supply
Filtered, regulated air for the clamp and press cylinders on a stamping press, with the 5 um element protecting direction valves from particles and the manual drain suiting a press attended every shift.
Multi-gun spray finishing manifold
Point-of-use pressure control on a multi-gun paint spray line, where each 1/2in drop needs its own regulated, filtered air ahead of the spray guns.
Carton sealer air prep
Filtered, regulated air for the cylinder set on a carton sealing machine, taken from the 1/2in main drop ahead of the machine's distribution manifold.
Is the Airtac GFR Filter Regulator GFR400C15MJNW the Right Unit?
Match the frame to the air demand of the line, not just the existing pipe thread: sizes 200, 300, 400 and 600 step up through ports from 1/8in to 1in, and this unit carries the 1/2in PT port. Manual drainage suits points an operator visits on a schedule; automatic and differential-pressure drains are available on the same frame if you would rather not rely on draining by hand. The W suffix gives the 5 um element - choose it where downstream valves and cylinders need finer air than the standard 40 um grade provides. No gauge is fitted; a gauge with an MPa, psi or bar scale can be added when ordering. Threads are PT as standard, with G (BSPP) and NPT as ordering options, and the J suffix omits the mounting bracket. Because rated flow is published as curves and not a single number, send us your flow requirement and we will confirm sizing against the AirTAC datasheet before you order.
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 GFR400C15MJNW FAQ
AirTAC publishes flow for the GFR series as performance curves rather than a single rated figure, so there is no one number we can honestly quote here. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet on request.
The M suffix means the bowl is drained by hand, which suits cells and cabinets an operator visits regularly; automatic and differential-pressure drains are available on the same frame. The W suffix fits the 5 um element instead of the standard 40 um grade, for finer protection of downstream valves and cylinders.
