AirTAC GFR400-10 Filter Regulator (GFR40010LF1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010LF1) 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 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 (GFR40010LF1)
The AirTAC GFR40010LF1 is a filter regulator in one body: it removes water and particulate from the compressed-air line and regulates downstream pressure, with a drain bowl to collect condensate. This 400-size configuration has a 3/8in PT port, the standard 40 um filtration element, a mounting bracket included, and the L code makes it the low-pressure regulator type - adjustment is up to 0.4 MPa, for circuits set below the standard range. The F1 code adds a square gauge with MPa scale. Maximum working pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the drain is the standard differential-pressure type. The bowl is PC (polycarbonate) at this size.
This is a genuine AirTAC part from the G series, sold here in the US market. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, with your choice of drain type, filter grade (40 um standard, 5 um W option), gauge type and scale, thread (PT standard; G and NPT orderable) and bracket. Because AirTAC publishes flow for this series as performance curves rather than a single rated figure, we confirm exact flow and full datasheet values 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. 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.

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 GFR400-10 Filter Regulator (GFR40010LF1) Is Used
Air to tailgate and clamp actuators on delivery vehicles
Low-pressure regulated air for liftgate, door and load-securing cylinders on trucks and trailers: the low-pressure regulator type matches these moderate-force jobs, and the square MPa gauge is easy to read on a maintenance stop.
Bench air at a maintenance workshop station
A regulated drop for air tools and test rigs run at reduced pressure: the L-coded regulator protects lower-pressure work, the 40 um element removes water and coarse dirt, and the square MPa gauge shows the setpoint at a glance.
Pneumatic tooling on a sheet-metal fabrication bench
Regulated air for press-brake part clamps and bench shears run at reduced settings: the low-pressure type avoids over-driving light-duty tooling, while the filter keeps condensate and particulate out of the tool circuit.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010LF1) the Right Unit?
Pick this model for reduced-pressure circuits where you want a square-gauge readout: the L-coded low-pressure regulator type adjusts up to 0.4 MPa and the F1 code brings the square MPa gauge. Size 400 with a 3/8in PT port covers mid-to-large branch lines - step to 600 for bigger ports or to 300/200 for smaller ones, and let us verify flow against the published curves for your duty before ordering. Filtration is the standard 40 um element; select the W option for 5 um air. The drain is the differential-pressure type, with automatic and manual variants orderable, and the bracket is included. PT is the standard thread; G and NPT are orderable options.
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 (GFR40010LF1) FAQ
There is no single rated flow figure we can quote: AirTAC publishes flow for the G series as performance curves. Ask us and we will confirm the flow and full datasheet values for this 3/8in low-pressure unit against your application before you order.
F1 adds the square gauge with MPa scale, so the regulated setpoint is readable at the unit. The L code makes this the low-pressure regulator type with adjustment up to 0.4 MPa, filtration is the standard 40 um element, the drain is the standard differential-pressure type, the bracket is included, and the port is PT 3/8in with G and NPT orderable.
