AirTAC GFR400-10 Filter Regulator (GFR40010AC1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010AC1) 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 automatic 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 (GFR40010AC1)
The AirTAC GFR series cleans and regulates compressed air in a single body: a filter stage with condensate bowl, followed by a pressure regulator. This GFR40010AC1 is the 400 size with 3/8 in PT ports, the standard 40 um element, an automatic drain that ejects collected condensate without operator attention, and a round external pressure gauge reading in MPa for setting and checking downstream pressure.
It is a genuine AirTAC part for compressed air, rated to 1.0 MPa (145 psi) maximum inlet with a regulator setting range of 0.15-0.9 MPa (20-130 psi) and -5 to 70 C (non-freezing) operation. The 400 size carries a PC (polycarbonate) bowl and a mounting bracket; PT is the standard thread, with G (BSPP) and NPT versions, other sizes and drain types as catalogue options. AirTAC publishes flow for this series as curves, not a single rating - ask us and we will confirm the datasheet figures for your line.

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.
Size Class

- GFR600PT3/4" - PT1"
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 (GFR40010AC1) Is Used
Furniture plant nailing cell
Filtered, regulated air for nailer and stapler stations on an upholstery line; the automatic drain keeps condensate out of the tool feed between shifts.
Sorting-gate actuation panel
A regulated 3/8 in supply for diverter and gate cylinders on an automated sorting line, with the MPa gauge giving setters a visible set point.
Trailer assembly air tools
Point-of-use conditioning for impact wrenches and air ratchets at a trailer assembly bay, holding a steady regulator setting as the tools cycle.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010AC1) the Right Unit?
The 400 body with 3/8 in PT ports is the mid-size step in the G series - if your flow curve outgrows it, the next step is a larger port or the 600 body. Drain choice is the main running decision: the A code here gives an automatic drain that clears the bowl unattended, while the M code gives a manual drain for supervised cells. The standard 40 um element suits general actuation; specify the W code for a 5 um element where downstream valves are finer. The round gauge reads in MPa; psi or bar scales can be specified instead. PT is standard, with G (BSPP) and NPT to order. Flow is published as curves, not a single rating, 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 (GFR40010AC1) FAQ
There is no single rated figure to quote: AirTAC publishes G-series flow as curves against pressure. Tell us the flow and pressure your line needs and we will confirm the sizing from the datasheet before you order.
Yes - drain type and gauge are ordering choices in the G series. The A code on this model is the automatic drain; an M code gives manual draining, and the round gauge can be supplied in MPa (as here), psi or bar scales. We will confirm the exact variant and its datasheet on request.
