Airtac GFR Filter Regulator GFR300C15JC1
The AirTAC Airtac GFR Filter Regulator GFR300C15JC1 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 GFR300C15JC1
The GFR300C15JC1 is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body, with no lubricator. This configuration is a size 300 unit with PT-threaded 1/2 in ports (PT is the standard thread; G and NPT are catalogue options), the standard 40 um filter element, the standard differential-pressure drain, a round pressure gauge reading in MPa, and no mounting bracket (J). The polycarbonate bowl collects water and particulate ahead of the regulated outlet.
This is a genuine AirTAC part. G-series filter regulators are offered in sizes 200, 300, 400 and 600 with a choice of ports, drains, 40 um or 5 um elements, gauges, brackets and check valves. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details for your application.

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 GFR300C15JC1 Is Used
Assembly hall ring-main drops
Installed at 1/2 in take-off points from a plant air ring main to give each assembly workstation clean, regulated air at a fixed line pressure.
Panel-mounted pneumatic control section
Mounted inside an electrical cabinet's pneumatic section, feeding solenoid valve manifolds and air-assisted components without needing its own bracket.
Bottling line conveyor air blast
Conditions the supply to air nozzles that dry containers on a bottling conveyor, keeping nozzle pressure steady as line demand fluctuates.
Is the Airtac GFR Filter Regulator GFR300C15JC1 the Right Unit?
Size 300 with 1/2 in PT ports suits air branches serving multiple actuators or larger valves; step to 400/600 for more capacity or 200/300 for smaller drops. Element choice is 40 um standard (this unit) or 5 um (W) for finer filtration. The regulator adjusts 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain fitted here; manual-drain variants adjust 0.05-0.9 MPa (7-130 psi). Choose the J no-bracket build only where your manifold or panel already secures the unit, and select gauge style and MPa/psi/bar scale, automatic or manual drain, check valve (K), and G or NPT thread as needed. Flow is published as curves, not a single rating, so let us 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 GFR300C15JC1 FAQ
Flow for G-series filter regulators is published as characteristic curves rather than a single rated figure, so no one number is stated here. Give us your line pressure and demand and we will confirm sizing from the datasheet on request.
J specifies the no-bracket build, so plan on securing the unit via its ports or your own manifold; versions without J include a bracket. The drain is the standard differential-pressure type, with automatic (A) and manual (M) drains available as variants on the same size.
