Airtac GFR Filter Regulator GFR300C15C1W
The AirTAC GFR Filter Regulator GFR300C15C1W 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 GFR300C15C1W
GFR300C15C1W is a genuine AirTAC G-series filter regulator fitted with the fine 5 um filter element (code W): one body that removes water and finer particulate from compressed air and regulates downstream pressure. This 300-size unit has standard PT1/2 ports, a differential-pressure drain in the polycarbonate bowl, and an external round gauge on an MPa scale (code C1). Max inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the unit runs on compressed air only at -5 to 70 C.
This is a genuine AirTAC part from the G-series 200/300/400/600 range, with port options from 1/8 to 1 inch, G (BSPP) or NPT thread options, drain and filtration choices, and gauge configurations to suit the panel. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet for your application before ordering.

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.
Size Class

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 GFR300C15C1W Is Used
Analytical instrument air feed
Filtered, regulated air supplies sample-handling actuators on laboratory analysers, where the 5 um element keeps fine contamination away from sensitive pneumatic components.
Optical assembly measurement fixtures
Air to clamping and positioning fixtures on an optical assembly cell is filtered to 5 um and held at a set, dial-checked pressure for repeatable part seating.
Furniture spray finishing line
Conditioned air ahead of the spray guns on a furniture finishing line helps keep water and grit out of the finish, with pressure set at the gun drop.
Is the Airtac GFR Filter Regulator GFR300C15C1W the Right Unit?
Size 300 with PT1/2 ports is the mid-range step of the G-series; step up or down by port size to match the flow your circuit needs, which we can confirm against the published curves on request. The W in this code selects the 5 um element over the 40 um standard - choose it where valves, cylinders or processes are sensitive to finer contamination. Drain choices are differential-pressure (default, as here), automatic (A) and manual (M, which widens the regulator range to 0.05-0.9 MPa / 7-130 psi). Gauge options are the embedded square gauge or this external round gauge in MPa, psi or bar scale. PT is the standard thread; order G (BSPP) or NPT as options. A bracket is included unless J is specified.
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 GFR300C15C1W FAQ
AirTAC publishes G-series flow as curves, not a single rated figure, so we do not quote a number here. Send us your flow and pressure conditions and we will confirm sizing from the datasheet before you order.
Choose W (5 um) where downstream valves, instruments or processes are sensitive to finer particles, and the standard 40 um for general plant air conditioning. It is a simple code option on the same GFR300 body.
