Airtac GFR Filter Regulator GFR400C15JF1K
The AirTAC GFR Filter Regulator GFR400C15JF1K 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 GFR400C15JF1K
The GFR400C15JF1K is an AirTAC G-series filter regulator that cleans compressed air and regulates downstream pressure in one body. This 400-size configuration carries the standard 40 um element, a differential-pressure drain, the embedded square pressure gauge scaled in MPa, and a reverse (check) valve on the 1/2 in PT port. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family is made in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and thread options PT (standard), G (BSPP) or NPT; drains are differential-pressure, automatic or manual and elements 40 um standard or 5 um (W). Flow is published as curves rather than a single rating, so we confirm datasheet figures 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 GFR400C15JF1K Is Used
Trailer brake-test rig air prep
Filtering and regulating the shop-air supply to a commercial-trailer brake test station, where the check valve holds the set pressure while the rig's cylinders cycle.
Press-shop clamp circuits
Conditioning air to the clamping and ejection cylinders of a mechanical press line, keeping dirt and water out of the valves and holding a constant clamp pressure.
Maintenance-shop service stations
A filtered, regulated outlet at a plant maintenance shop where technicians plug in impact tools and blow guns, with the check valve keeping the station setting stable.
Is the Airtac GFR Filter Regulator GFR400C15JF1K the Right Unit?
The built-in check valve (K) is the differentiator on this code: it suits installations where a backfeed from the downstream manifold could upset the regulator setting. Otherwise the choices are the same as the rest of the 400-size family: keep the 40 um standard element or order the 5 um W grade, choose differential-pressure (this code), automatic or manual drain, and pick the square embedded gauge in MPa (1), psi (2) or bar (3) scale. PT is the standard thread with G and NPT as orderable options, and the J code means order the bracket separately.
Flow is published as curves, not a single rating, so ask us to 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 GFR400C15JF1K FAQ
We do not quote a single rated flow because AirTAC publishes G-series performance as curves, not as one figure. Share your inlet pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the GFR400C15 datasheet on request.
Only by the reverse (check) valve: the K code has one fitted, so downstream air cannot flow back through the unit and the regulated setting is held. Filtration (40 um standard element), the differential-pressure drain, the square MPa gauge, the 1/2 in PT port and the 0.15-0.9 MPa (20-130 psi) adjustment range are otherwise the same.
