Airtac GFR Filter Regulator GFR300C10JN
The AirTAC GFR Filter Regulator GFR300C10JN 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 GFR300C10JN
GFR300C10JN is an AirTAC G-series filter regulator: one body that removes water and particulate from compressed air and holds a steady downstream pressure. This 300-size build has PT3/8in ports (PT is the standard thread), the standard 40um element, a differential-pressure drain, no gauge (N) and no mounting bracket (J). Max working pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C. The polycarbonate bowl collects condensate, and with the differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The G series runs from size 200 to 600 with ports from 1/8in to 1in, and this family can be ordered with 5um filtration, automatic or manual drains, embedded square or external round gauges, a reverse valve and G or NPT threads. Flow is published as curves rather than a single rating, so tell us your air demand and we will confirm sizing and 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 GFR300C10JN Is Used
CNC machine-shop air supply
Installed ahead of the solenoid valves on a machining centre, it strips water from the shop compressor ring and holds the pressure the tool-changer and clamping circuits expect.
Packaging line actuators
Mounted on a cartoning or shrink-wrap machine, it feeds film-seal cylinders and vacuum generators with clean, regulated air so seal pressure stays repeatable through the shift.
Lab automation skid
On a pilot-scale process skid it conditions the air feeding pneumatic dosing pumps and sample valves, protecting close-tolerance components from water and debris.
Is the Airtac GFR Filter Regulator GFR300C10JN the Right Unit?
Size 300 with a 3/8in PT port sits mid-range in the G series; step down to 200 or up to 400/600 according to the flow your line needs, and we will confirm sizing from the curves. The standard 40um element suits general plant air; choose the W variant for a 5um element where downstream components are finer. Drain here is differential-pressure; automatic (A) or manual (M) builds exist if you prefer. The JN code omits the bracket and the gauge - add a bracket if you panel-mount, and pick a square embedded or external round gauge scaled in MPa, psi or bar if you want a local readout. PT is the standard thread; G (BSPP) and NPT are orderable options.
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 GFR300C10JN FAQ
AirTAC publishes G-series performance as flow curves rather than a single rated figure, so we do not quote a number on the page. Send us your application and required flow and we will confirm the correct size and datasheet figures on request.
The N and J positions in the code mean the gauge and mounting bracket are omitted from this variant. Gauges (embedded square or external round, scaled in MPa, psi or bar) and brackets are available on other GFR300 builds if you want them.
