Airtac GFR Filter Regulator GFR400C15JNK
The AirTAC GFR Filter Regulator GFR400C15JNK 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 GFR400C15JNK
The AirTAC GFR400C15JNK is a genuine AirTAC filter regulator combining filtration and pressure regulation in one 400-size body, fitted with a built-in check valve (K) that blocks reverse flow through the unit. This configuration carries a 1/2 inch PT port, the standard 40 um filter element and a differential-pressure drain that releases collected condensate as pressure differential builds. No gauge is fitted (N) and no mounting bracket is included (J).
As a genuine AirTAC part, the GFR400 series offers 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 scales, optional check valve, 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 ask us and 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.

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 GFR400C15JNK Is Used
Pneumatic press and clamp circuit
Conditions and regulates the supply to a pneumatic press or fixture-clamping circuit, where the fitted check valve helps hold the regulated pressure at the clamps if the shop-air supply momentarily drops.
Trailer and body-building air circuits
Provides filtered, regulated air for tail-lift, door and body-control actuators built into commercial vehicles and trailers, using the standard 40 um element ahead of control valves.
Maintenance shop service drop
Installed at a maintenance-bay service drop to give technicians one regulated 1/2 inch outlet for impact tools, blow guns and test rigs, with condensate handled by the differential-pressure drain.
Is the Airtac GFR Filter Regulator GFR400C15JNK the Right Unit?
Pick this code when you want the standard 400-size, 1/2 inch PT filter regulator with 40 um filtration plus the check-valve option - useful where the regulated setting should be held if upstream pressure is interrupted. Without the K option the same body is available as the GFR400C15JN. Drain choices are differential-pressure (this model), automatic (A) or manual (M); the regulation range is 0.15-0.9 MPa (20-130 psi) with the differential-pressure or automatic drain, or 0.05-0.9 MPa (7-130 psi) with the manual drain.
Thread is PT as standard, with G (BSPP) and NPT as ordering options. No gauge is fitted; square embedded gauges (MPa, psi or bar) and an external round gauge are available on other variants, and a mounting bracket can be ordered. Because flow is published as curves rather than a single rating, send us your operating conditions and we will confirm sizing against 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 GFR400C15JNK FAQ
We do not quote a single rated flow because AirTAC publishes G-series flow as characteristic curves, not as one number. Provide your inlet pressure, set pressure and air demand, and we will confirm the flow figures from the datasheet for this exact model on request.
On this model the differential-pressure drain gives a regulation range of 0.15-0.9 MPa (20-130 psi). If you order the manual-drain variant (M) of the same 400-size body, the range widens to 0.05-0.9 MPa (7-130 psi); the automatic-drain variant (A) keeps the 0.15-0.9 MPa range. Choose the drain to match how much condensate your line produces and how the unit is attended.
