Airtac GFR Filter Regulator GFR400C15JF1
The AirTAC GFR Filter Regulator GFR400C15JF1 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 GFR400C15JF1
The GFR400C15JF1 is an AirTAC G-series filter regulator: water and particulate are removed from compressed air and the downstream pressure is regulated in a single body. This 400-size configuration uses the standard 40 um element, a differential-pressure drain, and the embedded square pressure gauge scaled in MPa, on a 1/2 in PT port. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator family spans 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 can be differential-pressure, automatic or manual and elements 40 um standard or 5 um (W). Flow for the series is published as curves rather than one 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 GFR400C15JF1 Is Used
Assembly plant air drops
Point-of-use conditioning on compressed-air drop lines feeding assembly benches, giving operators filtered air at a fixed regulator setting for air tools and fixtures.
PLC-controlled palletizer circuits
Conditioning the supply to the solenoid valve manifold of a palletizer's grip-and-place cylinders, protecting valves from water and dirt while holding a stable pressure.
Automotive paint shop air prep
First-stage water and particle removal ahead of process equipment in an automotive body shop, where the differential-pressure drain copes with condensate in the main.
Is the Airtac GFR Filter Regulator GFR400C15JF1 the Right Unit?
For a 1/2 in air main, size 400 matches the common port step; move to 600 for larger mains or 300 where the demand is lighter. This code keeps the standard 40 um element and the differential-pressure drain, which discharges condensate as the pressure across the bowl changes; automatic (A) and manual (M) drains are orderable on the same body. The embedded square gauge here reads in MPa (scale 1); psi (2) or bar (3) scales are orderable. PT is the standard thread, with G (BSPP) and NPT as catalogue options, and the J code means a bracket must be ordered 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 GFR400C15JF1 FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not state one number here. Tell us your inlet pressure, downstream demand and allowable pressure drop and we will confirm sizing from the GFR400C15 datasheet on request.
This code uses the differential-pressure drain, the default, which discharges condensate as the pressure difference across the bowl changes. Automatic (A) drains eject condensate on their own, and manual (M) drains are emptied by hand. With the differential or automatic drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi); the manual-drain variant widens it downward to 0.05 MPa (7 psi).
