Airtac GFR Filter Regulator GFR400C10JNK
The AirTAC GFR Filter Regulator GFR400C10JNK 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 GFR400C10JNK
The AirTAC GFR series filters and regulates compressed air in one body: a 40 um element removes water and particulate, and the regulator holds a steady downstream pressure adjustable between 0.15 and 0.9 MPa (20-130 psi) with the differential-pressure drain this code specifies. The K in GFR400C10JNK adds a reverse (check) valve, so air held downstream cannot flow back through the unit when the upstream supply is vented or the compressor unloads. This size 400 unit has a 3/8 in PT port, no gauge (N) and no mounting bracket (J); the polycarbonate bowl suits non-freezing air from -5 to 70 C at up to 1.0 MPa (145 psi) inlet.
It is a genuine AirTAC part. The G series covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus drain, filter-grade, gauge, bracket and thread options in G (BSPP) or NPT as well as PT. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 GFR400C10JNK Is Used
Pneumatic press hold circuits
On a bench pneumatic press, the built-in check valve keeps the regulated pressure trapped downstream when the compressor unloads or the upstream valve vents, so the workpiece stays clamped between strokes.
Packaging machine supply on a snack-food line
Filtering and regulating the air feeding bagger and cartoner actuators on a snack-food packaging line, with the check valve holding actuator pressure while the plant air header cycles.
Control-valve actuation on a water-treatment skid
Regulating air to diaphragm-actuated control valves on a water-treatment skid; the reverse valve stops backflow through the unit when the air header is isolated for service.
Is the Airtac GFR Filter Regulator GFR400C10JNK the Right Unit?
Pick this JNK build over the plain GFR400C10JN whenever downstream pressure must be trapped - clamps, presses or cylinders that must not relax when the supply side drops. Filtration and regulation are unchanged: 40 um standard element, 0.15-0.9 MPa regulation with the differential-pressure drain (0.05-0.9 MPa if you choose the manual-drain code instead), and a 3/8 in PT port that steps to 1/2 in on the 15 code. Gauge (N means none here), bracket, 5 um element and G or NPT thread variants can all be ordered.
AirTAC publishes flow as curves, not one rated number, so share your pressure and demand points and we will confirm sizing from the datasheet 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 GFR400C10JNK FAQ
We do not quote a single rated flow because AirTAC publishes G-series performance as curves, not one number. Tell us your supply pressure, set pressure and air demand, and we will confirm the sizing data from the datasheet on request.
K fits a reverse (check) valve, so downstream air cannot flow back through the unit - useful for holding regulated pressure on cylinders and tools while the supply side is vented or the compressor unloads. Everything else decodes the same as the plain GFR400C10JN: 3/8 in PT port, 40 um element, differential drain, no gauge and no bracket.
