Airtac GFR Filter Regulator GFR400C10MF1W
The AirTAC GFR Filter Regulator GFR400C10MF1W 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 GFR400C10MF1W
The GFR400C10MF1W is an AirTAC G-series filter regulator fitted with the fine 5 um filter element (the W code): water and particulate removal plus downstream pressure regulation in one body. This configuration is the 400 size with a 3/8 in PT port and a manual drain you open by hand to empty the bowl. An embedded square gauge on an MPa scale shows the regulated pressure, the adjustment range is 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series 200/300/400/600 size range, with catalogue options across port sizes, thread types (PT standard, with G and NPT as orderable variants), drain types, the 40 um and 5 um filter grades, and gauges. Series flow is published as performance curves rather than a single rated figure, so we confirm sizing and full datasheet 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 GFR400C10MF1W Is Used
Laboratory instrument air
Feed clean, regulated air to pneumatic actuators and purge lines on laboratory bench equipment, with the 5 um element guarding against fine particulate carryover.
Spray booth gun supply
Supply the spray guns in a small paint or coating booth with filtered, regulated air, using the fine element to support consistent atomisation quality.
Workshop air tool bench
Regulate the air feeding hand-held impact and ratchet tools at a maintenance workshop bench, with the manual drain emptied as part of the daily check.
Is the Airtac GFR Filter Regulator GFR400C10MF1W the Right Unit?
Pick your size and port on the 200/300/400/600 ladder; this 400 unit carries a 3/8 in PT port. The W code is the key choice here: it orders the 5 um element instead of the 40 um standard, for cleaner air where the downstream equipment needs it. Drain is manual (M), with automatic and differential-pressure variants available; manual drain gives the wider 0.05-0.9 MPa (7-130 psi) regulator range. The square gauge reads in MPa; psi and bar scales and an external round gauge are catalogue options. Thread is PT standard, with G (BSPP) and NPT orderable, and J variants omit the bracket. Flow is published as curves, not a single rating - 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 GFR400C10MF1W FAQ
AirTAC publishes G-series capacity as performance curves rather than a single rated-flow figure, so we do not quote a number here. Tell us your application's pressure and demand and we will confirm sizing and the curve data from the datasheet on request.
The W code (5 um) suits air feeds where finer particulate would otherwise reach sensitive equipment such as spray guns, instruments or precision valves. The standard grade is 40 um and flows through the same GFR body, so both grades can be compared on the same datasheet on request.
