Airtac GFR Filter Regulator GFR400C10MN
The AirTAC GFR Filter Regulator GFR400C10MN 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 GFR400C10MN
GFR400C10MN is a genuine AirTAC G-series filter regulator: filtration and pressure regulation built into one body. Incoming compressed air passes a 40 um filter element and collects in the polycarbonate drain bowl (size 400 frame), where water and particulate are released through the manual drain; downstream pressure is then set anywhere in the 0.05-0.9 MPa (7-130 psi) range with the adjustment knob. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the connection is a 3/8 in PT tapered port - PT is the standard thread, with G (BSPP) and NPT available as catalogue options.
This configuration is ordered without a pressure gauge (code position N), and a mounting bracket is included. This is a genuine AirTAC part: the G series spans four frame sizes (200, 300, 400, 600) with ports from 1/8 to 1 in, and drain, filter-grade, gauge, thread and check-valve options can be mixed to match the line. AirTAC publishes flow capacity as curves rather than a single rated figure, so share your application conditions with us and we will confirm sizing and send the full datasheet 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 GFR400C10MN Is Used
CNC tool-clamp circuit
Set a stable, reduced pressure feeding the tool-change and workpiece-clamping cylinders of a CNC lathe or machining centre, with water and particulate stripped out ahead of the directional valves.
Packaging machine air prep
Feed the cylinder and actuator supply on a cartoning or case-sealing conveyor line, holding the set pressure at the machine while the manual-drain bowl is emptied during shift checks.
Robot gripper panel
Regulate supply air to a robotic pick-and-place cell's gripper manifold and control panel, where a combined filter-regulator body saves panel space over separate filter and regulator units.
Is the Airtac GFR Filter Regulator GFR400C10MN the Right Unit?
Size 400 is the second-largest G-series frame; move to 300 or up to 600 when the line's pipe diameter or air demand changes, and match the port (1/8 to 1 in across the series) to the piping. The M in this code fixes a manual drain - the bowl is emptied by hand - which suits attended equipment; choose an A-coded unit for automatic draining. Filtration here is the standard 40 um grade; add W to the code for the optional 5 um element where finer protection is needed. No gauge is fitted, but round or square gauges with MPa, psi or bar scales can be ordered if a local pressure readout is required. Thread is PT as standard, with G (BSPP) and NPT selectable, and the mounting bracket is included. Because 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 GFR400C10MN FAQ
AirTAC publishes G-series capacity as flow curves rather than one rated figure, so we do not quote a number here. Tell us your inlet pressure, port size and required downstream flow, and we will confirm sizing from the datasheet on request.
M is a manual drain, so the bowl is emptied by hand, and N means no pressure gauge is fitted - round or square gauges with MPa, psi or bar scales can be added instead. With a manual drain, the regulated output covers 0.05-0.9 MPa (7-130 psi).
