AirTAC GFR400-10 Filter Regulator (GFR40010LC1W)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010LC1W) 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 (GFR40010LC1W)
The AirTAC GFR40010LC1W 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 W-coded 5 um filtration element instead of the standard 40 um, 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. A round external pressure gauge with MPa scale is included (C1). 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, 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.
Model Code: AirTAC GFR400-10 Filter Regulator (GFR40010LC1W)
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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 (GFR40010LC1W) Is Used
Pilot air for precision pneumatic valves
Feeding pilot stages of process valves that need clean, low-pressure air: the 5 um element keeps fine particulate out of small pilot orifices, and the low-pressure regulator type holds a gentle, repeatable setpoint.
Sample-handling actuators on an analytical instrument bench
Low-force cylinders that index samples and trays on laboratory equipment: the low-pressure setting protects delicate samples, the 5 um grade suits the instrument's small-bore valves, and the MPa gauge documents the setpoint.
Instrument air to a control panel on a process skid
A regulated, filtered branch feeding panel-mounted indicators, transducers and small actuators on a skid: the low-pressure regulator type matches instrument supply levels, and the gauge gives operators a direct MPa reading.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010LC1W) the Right Unit?
This is the fine-air version of the low-pressure 400-size unit: the W element filters to 5 um for valves, cylinders and instruments that need cleaner air, while the L-coded low-pressure regulator type holds setpoints up to 0.4 MPa. The included round MPa gauge makes the setting visible at the point of use. Size 400 with a 3/8in PT port serves mid-to-large branch lines; step down to 300/200 or up to 600 depending on your port and flow needs - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The drain is the standard differential-pressure type, with automatic and manual variants orderable; PT is the standard thread with G and NPT to order, and the bracket is included.
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 (GFR40010LC1W) FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated number, so we do not quote a figure here. Tell us your pressure and demand and we will confirm the flow and full datasheet values for this 3/8in, 5 um low-pressure unit before you order.
Only the filter grade changes: W selects the 5 um element in place of the standard 40 um, for air that feeds finer valves and instruments. Everything else is the same - low-pressure regulator type (L) with adjustment up to 0.4 MPa, round MPa gauge (C1), differential-pressure drain, included bracket and PT 3/8in port.
