Airtac GFR Filter Regulator GFR400C10MC1W
The AirTAC GFR Filter Regulator GFR400C10MC1W 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 GFR400C10MC1W
GFR400C10MC1W is a genuine AirTAC G-series filter regulator: a 5 um filter and a pressure regulator combined in one body, with a 3/8 in PT port. The W code selects the finer 5 um element instead of the standard 40 um, for cleaner air downstream. This configuration has a manual drain bowl (polycarbonate on size 400), the standard embedded square pressure gauge plus an external round MPa gauge (code C1), and a regulator adjustment range of 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part from the G series, which runs from size 200 to 600 with ports from 1/8 to 1 in, and offers drain, filter-grade, gauge, thread (PT standard, G and NPT options) and bracket choices. AirTAC publishes flow as curves rather than a single rating, so we confirm flow and 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 GFR400C10MC1W Is Used
Pneumatic measuring fixtures
Fine 5 um filtered, regulated air to gauging and probing fixtures on a machining line, where sensitive pneumatic components sit downstream of the unit.
Analytical sample handling
Clean regulated air for pneumatic valves and actuators on a laboratory or process sample-handling panel, with the 5 um element protecting fine instrumentation.
Electronics assembly benches
Conditioned air to pick-and-place and screw-driving stations on an electronics assembly line, combining fine filtration with a stable set pressure at each bench.
Is the Airtac GFR Filter Regulator GFR400C10MC1W the Right Unit?
Size 400 with a 3/8 in PT port sits mid-range in the G series (sizes 200/300/400/600, ports 1/8 to 1 in); step the size to match your pipework, since larger sizes carry more flow. This unit has a manual drain, so condensate is discharged by hand and the adjustment range is 0.05-0.9 MPa (7-130 psi). The W code selects 5 um filtration rather than the 40 um standard - choose it when valves, cylinders or tools need finer particle removal. The C1 code adds an external round MPa gauge on top of the standard embedded square gauge. Thread is PT as standard; G (BSPP) and NPT are catalogue options, and a bracket is included.
AirTAC publishes flow as curves rather than 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 GFR400C10MC1W FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so no rated flow number is quoted here. Note also that a finer element influences the pressure-drop curve. Send us your operating pressure and air demand and we will confirm the flow from the datasheet before you order.
The standard element is 40 um, which suits general plant air. The W code selects a 5 um element for downstream equipment that needs finer particle removal, such as precision valves, instrumentation or air tools with tight clearances. If you need both grades in one line, fit two units in series - we can help you spec that on request.
