Airtac GFR Filter Regulator GFR400C15JN
The AirTAC GFR Filter Regulator GFR400C15JN 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 GFR400C15JN
The AirTAC GFR400C15JN is a genuine AirTAC filter regulator: filtration and pressure regulation in one 400-size body. This configuration has a 1/2 inch PT port, the standard 40 um filter element and a differential-pressure drain that discharges collected condensate automatically as differential pressure builds. The N code means no gauge is fitted, keeping the unit compact where a separate gauge or no indication is preferred, and J means no mounting bracket is included.
As a genuine AirTAC part, the GFR400 family spans sizes 200, 300, 400 and 600 with 40 um standard or 5 um (W) elements, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar, an optional check valve (K), and PT, G or NPT threads. Maximum working pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we will confirm datasheet figures 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. 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.

| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 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) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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 GFR400C15JN Is Used
Conveyor diverter and stopper gates
Conditions the air feeding diverters, stoppers and lift gates along a conveyor line from one 1/2 inch branch, giving the whole gate group one filtered, regulated supply.
Bottling line rinse and fill headers
Feeds the clamp, lift and valve-actuation cylinders of a bottling line, with the differential-pressure drain taking care of condensate carried in from the ring main without daily operator attention.
Panel-mounted pneumatic control section
Sits as the conditioning block in a control panel where the machine already has its own pressure indication, so the N (no gauge) variant keeps the footprint and panel layout clean.
Is the Airtac GFR Filter Regulator GFR400C15JN the Right Unit?
This is the streamlined 400-size variant: 1/2 inch PT port, standard 40 um filtration for general cylinder, valve and actuator protection, and the default differential-pressure drain. Choose the A (automatic) drain if condensate loads are heavy and the line runs unattended, or M (manual) for a controlled, low-flow dump; regulation range then follows the drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, or 0.05-0.9 MPa (7-130 psi) with manual drain.
No gauge is fitted on this model; add a variant with the embedded square gauge (MPa, psi or bar scale) or the external round gauge if a local setpoint readout is wanted. Thread is PT as standard with G and NPT as ordering options, and a bracket is available if panel fixing is required. Flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet 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 GFR400C15JN FAQ
AirTAC does not publish a single rated flow figure for the G-series; flow is given as characteristic curves against pressure. Send us your line pressure, set pressure and consumption, and we will confirm the curve values from the datasheet for this model on request so you can size it correctly.
The N in the code means no pressure gauge is fitted, which suits installations that already display line pressure elsewhere. If you want local indication, the same GFR400 body is available with the embedded square gauge in MPa, psi or bar scale, or with an external round gauge - just order the matching variant code.
