AirTAC GFR400-10 Filter Regulator (GFR40010LNW)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010LNW) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" 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 GFR400-10 Filter Regulator (GFR40010LNW)
The AirTAC GFR40010LNW is a filter regulator: filtration and pressure regulation combined in one body. Filtration comes first, so the regulated air downstream is already cleaned. This configuration is the size 400 body with a PT3/8 port, the low-pressure type regulator (adjustment up to 0.4 MPa), a fine 5 um filter element, a differential-pressure drain on the bowl, and no gauge fitted. The bowl is polycarbonate on this size, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part from the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8" to 1". Manual or automatic drains, 40 um or 5 um elements, gauges and G (BSPP) or NPT threads are available in the same series. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

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 GFR400-10 Filter Regulator (GFR40010LNW) Is Used
Low-pressure clamping fixtures
Supplies fixture clamp cylinders on a machining cell that hold workpieces at a deliberately low setpoint, with 5 um filtration protecting the clamp valves.
Glue and coating dispense heads
Feeds low-pressure adhesive or coating dispense stations where fine filtration and a gentle, stable regulated supply matter to bead quality.
Process valve actuator skids
Provides cleaned, low-pressure air to pneumatic valve actuators on a small process skid, with the differential drain keeping the bowl clear without operator attention.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010LNW) the Right Unit?
Size 400 with a 3/8" port suits mid-range air supply lines; step up or down in the G series if your flow demand moves beyond this body. The differential-pressure drain bleeds the bowl automatically as the pressure differential across the element builds, so no daily manual draining is needed. The 5 um element is the finer choice for downstream valves and actuators that tolerate less particulate than the standard 40 um grade. As the low-pressure type, this unit regulates up to 0.4 MPa; choose the standard type if your setpoint sits higher. The thread is PT as the standard; G (BSPP) and NPT are catalogue options to specify when ordering. A gauge is not fitted; an external round gauge can be ordered if you want a local reading.
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR400-10 Filter Regulator (GFR40010LNW) FAQ
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type, which adjusts up to 0.4 MPa instead of the standard range. It suits circuits that must run at gentle setpoints; for higher setpoints, choose the standard type in the same series.
