Airtac GFR Filter Regulator GFR300C15JC1WK
The AirTAC Airtac GFR Filter Regulator GFR300C15JC1WK 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 GFR300C15JC1WK
The GFR300C15JC1WK is an AirTAC G-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubricator. This configuration takes a 1/2 in PT port at size 300, carries the finer 5 um (W) filter element instead of the standard 40 um, drains condensate by differential pressure, and is fitted with a reverse (check) valve so downstream pressure is held if the supply drops. The J code means no mounting bracket, and C1 specifies an external round gauge with an MPa scale. With this drain type the regulation range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the PC bowl is rated for -5 to 70 C (non-freezing) compressed air.
This is a genuine AirTAC part. The G-series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus choices of drain type, 40 um or 5 um filtration, gauge style and scale, PT/G/NPT threads and brackets. Flow for GFR units is published as curves rather than a single rating, so we confirm datasheet figures on request before you order.

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 GFR300C15JC1WK Is Used
Paint line atomizing air
Feeding spray-gun atomizing air on a finishing line, where the 5 um element helps keep water and fine particulate out of the coating and the regulator holds a steady gun pressure.
CNC machine pneumatics
Supplying regulated air to a machining center's tool-clamp and chip-clearing circuits, with the check valve holding downstream pressure if the shop supply dips.
Lab automation skid
Conditioning air to a laboratory automation skid's pilot valves, where finer 5 um filtration and a stable setpoint protect sensitive instrumentation.
Is the Airtac GFR Filter Regulator GFR300C15JC1WK the Right Unit?
Size 300 with a 1/2 in port sits mid-range in the G-series; step up to 400/600 or down to 200 according to the flow your circuit needs, because flow is published as curves rather than a single rated figure - ask us to confirm sizing against your application before ordering. This unit keeps the default differential-pressure drain with its 0.15-0.9 MPa adjustment band; automatic or manual-drain variants exist if you need hands-off drainage or a wider 0.05-0.9 MPa band. The 5 um (W) element suits finer air-quality duties; the standard 40 um protects general actuators and valves. The C1 gauge is an external round type reading MPa; psi or bar scale variants and an embedded square gauge are also available. PT is the standard thread with G (BSPP) and NPT as catalogue options, and no bracket is included (J code).
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 GFR300C15JC1WK FAQ
AirTAC publishes filter-regulator flow as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the datasheet on request.
K fits a reverse (check) valve, so air does not flow back through the unit when upstream pressure falls - useful where a cylinder, clamp or vessel must hold its charge. Without the K the unit allows reverse flow.
