Airtac GFR Filter Regulator GFR400C15MNW
The AirTAC GFR Filter Regulator GFR400C15MNW 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 GFR400C15MNW
The GFR400C15MNW is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This configuration is the 400 size with a 1/2 in PT port, a manual drain, the 5 um (W) filtering element and no gauge fitted. It removes water and particulate from compressed air and holds a set downstream pressure; with the manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi) and the maximum inlet pressure is 1.0 MPa (145 psi). The bowl on the 400 size is polycarbonate (PC), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series runs from size 200 to 600, with 5 um (W) or standard 40 um elements, manual, automatic or differential-pressure drains, embedded square or optional external round gauges, and G (BSPP) or NPT thread options; a mounting bracket is included on this code. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the full datasheet 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 GFR400C15MNW Is Used
Pneumatic press air preparation
Feeding the clamping and pressing cylinders on a stamping or forming press: the element strips water and pipe scale from the shop-air main while the regulator holds a steady working pressure at the control valves.
Packaging machine valve supply
Supplying the directional valves and small cylinders on a carton-forming or bagging line, where clean, regulated air keeps jaw, seal and eject motions repeatable through the shift.
Conveyor diverters and stoppers
Regulating the air to divert gates, stoppers and lifters along a conveyor line, so product-handling cylinders see the same pressure at every station on the line.
Is the Airtac GFR Filter Regulator GFR400C15MNW the Right Unit?
Step through the G-series sizes (200/300/400/600) to match the port and flow your line needs; the 400 size with its 1/2 in PT port suits larger machine supply circuits. The M code gives a manual drain, the right choice when an operator can bleed the bowl as part of routine checks; the manual-drain version also regulates down to 0.05 MPa (7 psi), lower than the 0.15 MPa floor of the differential-pressure drain variants. The W code selects the 5 um element over the standard 40 um - choose 5 um where downstream valves or instruments need cleaner air. No gauge is fitted on this code; the series offers an embedded square gauge or an external round gauge with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GFR400C15MNW FAQ
AirTAC publishes flow for the GFR series as performance curves rather than a single rated figure, so we do not quote one number here. Send us your operating pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The M code means the bowl is emptied by hand as part of routine checks, which suits attended machines. With the manual drain the regulation range is 0.05-0.9 MPa (7-130 psi), reaching lower set pressures than the 0.15-0.9 MPa (20-130 psi) of the differential-pressure drain versions; an automatic drain is also available in the series.
