Airtac GFR Filter Regulator GFR400C15JC1K
The AirTAC GFR Filter Regulator GFR400C15JC1K 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 GFR400C15JC1K
The AirTAC GFR series is a filter regulator: compressed air is cleaned of water and particulate, then held at a set downstream pressure in one body. GFR400C15JC1K is the 400 size with 1/2 in PT ports, the standard 40 um filter element, a differential-pressure drain on the polycarbonate bowl and an external round gauge scaled in MPa. The trailing K means a reverse (check) valve is fitted, blocking reverse flow back through the unit; the J means the mounting bracket is omitted, available as an option. Maximum inlet pressure is 1.0 MPa (145 psi); with the differential-pressure drain the regulated output spans 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, which spans sizes 200 to 600 with 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet details 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.

|---|---|
| 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 GFR400C15JC1K Is Used
Bench pneumatic press
Running a light pneumatic press or bench crimper where the fitted check valve blocks reverse flow back toward the supply if the upstream line is momentarily lost.
Component test rigs
Providing a stable, regulated air supply to pneumatic component test benches in an engineering lab, with the check valve preventing backflow from the rig into the unit.
Palletising cells
Feeding the gripper and clamp circuits of a layer-palletising cell, where filtration ahead of the regulator helps protect the gripper solenoid valves.
Is the Airtac GFR Filter Regulator GFR400C15JC1K the Right Unit?
Size up by demand: 200, 300, 400 and 600 step up in port size and flow capacity, with the 400 frame carrying 1/2 in ports here. Selectable positions: drain (differential-pressure here, automatic or manual to order), filter grade (40 um standard, 5 um optional), gauge type and scale (round MPa here; square or round, MPa, psi or bar), thread (PT standard, G or NPT to order), bracket (omitted on this J-code) and the K check valve (fitted here; order without K if backflow prevention is handled elsewhere). Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR400C15JC1K FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so no single number can be given honestly. Send us your application details - supply pressure, demand and allowable pressure drop - and we will confirm the flow data and full datasheet on request.
K specifies that a reverse (check) valve is fitted, so air cannot flow backwards through the unit toward the supply side. If your circuit handles backflow prevention elsewhere, order the same unit without the K and we will confirm the correct code.
