Airtac GFR Filter Regulator GFR400C10AJNW
The AirTAC GFR Filter Regulator GFR400C10AJNW 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 GFR400C10AJNW
The GFR400C10AJNW is a genuine AirTAC G-series filter regulator fitted with the fine 5 um filter element (the W suffix): water and particulate removal plus downstream pressure regulation in one body. This size 400 configuration carries a 3/8 inch PT port, an automatic drain that purges condensate from the PC (polycarbonate) bowl unattended, and no mounting bracket (J) or pressure gauge (N). Maximum inlet pressure is 1.0 MPa (145 psi); with the automatic drain the regulating range is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing, with compressed air as the only medium.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain options (differential-pressure, automatic, manual), 40 um standard or 5 um fine elements, gauge versions with embedded square or external round indicators, the K check-valve option, and G (BSPP) or NPT threads as catalogue options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures and sizing for your line before ordering.

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.

| C1 | Port size See datasheet. 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)). |

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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 GFR400C10AJNW Is Used
Analytical instrument air supply
Conditioning the supply to pneumatic components of a lab analyzer or sampling system, where the 5 um element screens fine particulate that could upset small orifice components before it reaches them.
Sorting conveyor actuation
Filtered, regulated air for the diverters and stopper cylinders along a parcel-sort conveyor, with the 5 um grade protecting tightly toleranced valve spools from wear debris.
Test bench pressure control
A regulated, finely filtered supply branch on a pneumatic qualification bench, keeping test-piece inlet pressure steady and free of coarse contamination between the shop ring main and the fixture.
Is the Airtac GFR Filter Regulator GFR400C10AJNW the Right Unit?
The W suffix selects the 5 um element instead of the 40 um standard grade - the right call where sensitive valves, cylinders or instruments sit downstream; note that finer filtration clogs faster, so automatic drain (fitted here) and periodic element checks matter. Size 400 with a 3/8 inch PT port suits larger-bore tubing; step to sizes 200-600 as flow demands change. Manual drain (0.05-0.9 MPa regulating floor) and the differential-pressure default are the other drainage choices. Thread is PT as standard, with G (BSPP) and NPT orderable; J omits the bracket, N omits the gauge, and K adds a check valve if you need pressure hold. Flow is published as curves, not one rated figure, so have us 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 GFR400C10AJNW FAQ
AirTAC publishes G-series flow as curves against inlet pressure and pressure drop, not as a single rated figure, and the element grade is one of the variables on those curves, so we do not quote a number here. Send us your flow and pressure conditions and we will confirm sizing from the datasheet before you order.
The blank 40 um grade is the standard, economical choice for general actuation air. The W suffix selects the 5 um element for finer protection of sensitive downstream components, at the cost of faster loading and more frequent element attention. Both grades are catalogue options across the GFR400 size.
