Airtac GFR Filter Regulator GFR400C10AJN
The AirTAC GFR Filter Regulator GFR400C10AJN 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 GFR400C10AJN
The GFR400C10AJN is a genuine AirTAC G-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 400 configuration carries a 3/8 inch PT port, an automatic drain that ejects collected condensate from the PC (polycarbonate) bowl without operator attention, and a 40 um standard filter element. The J suffix means no mounting bracket is supplied and the N suffix means no pressure gauge is fitted. 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 or 5 um elements, gauge versions with embedded square or external round indicators, 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) | Pressure gauge fitted (blank). |
| (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 GFR400C10AJN Is Used
Packaging line air preparation
Point-of-use conditioning ahead of the cylinders and directional valves on a carton-forming and sealing machine: water and debris are drained out of the supply while the regulator holds a steady setting for consistent case clamping.
Paint booth atomizing supply
Feeding spray guns on a finishing line with clean, oil-free, pressure-stable air. A filter regulator (with no lubricator in the circuit) is the correct choice where atomizing air must stay dry and free of added oil mist.
Pneumatic press control circuit
Regulated supply to the pilot and main directional control valves of a bench pneumatic press, keeping actuation pressure within a fixed band regardless of header pressure swings in the shop air ring main.
Is the Airtac GFR Filter Regulator GFR400C10AJN the Right Unit?
Size 400 with a 3/8 inch PT port is the natural step for lines on larger-bore tubing; the same family steps from 200 up to 600 as port and flow demands grow - we confirm the flow curves against your application on request. For drainage, automatic (this code) suits unattended duty, manual gives the widest regulating floor (0.05-0.9 MPa), and differential-pressure is the family default. The element is 40 um standard; specify W for the 5 um grade where finer protection matters. Thread is PT as standard, with G (BSPP) and NPT as orderable options. J omits the mounting bracket, N omits the gauge (gauge-equipped versions exist in the family). Because published flow data is a set of curves rather than one rated figure, send us your operating conditions and we will confirm sizing before you order.
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 GFR400C10AJN FAQ
AirTAC publishes G-series flow as performance curves (against inlet pressure and pressure drop), not as a single rated figure, so we do not quote a number here. Send us your flow and pressure conditions and we will confirm the correct size from the datasheet before you order.
The trailing letters decode it: J = supplied without a mounting bracket and N = supplied without a pressure gauge. Both are catalogue choices - gauge-equipped GFR400 versions and bracketed configurations are available in the same family if your panel needs them.
