Airtac GFR Filter Regulator GFR300C15F1
The AirTAC GFR Filter Regulator GFR300C15F1 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 GFR300C15F1
GFR300C15F1 is an AirTAC GFR300-series filter regulator: water and particulate removal plus downstream pressure regulation in one body with a single polycarbonate bowl. This is the standard configuration for the 1/2 in PT size: 40 um filter element, differential-pressure drain, and the embedded square pressure gauge on an MPa scale. It handles compressed air only.
This is a genuine AirTAC part, rated for up to 1.0 MPa (145 psi) inlet, -5 to 70 C non-freezing, with a standard regulation range of 0.15-0.9 MPa (20-130 psi). The GFR family spans 200, 300, 400 and 600 sizes in 1/8 to 1 in ports, with 40 um or 5 um elements, differential, automatic or manual drains, an optional round external gauge, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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 GFR300C15F1 Is Used
Machine tool pneumatic control panel
Sets a stable working pressure for valves and actuators on the air preparation panel of a CNC machining centre or similar machine tool.
General plant drop-line preparation
Conditions air at the point of use on factory drop lines feeding assorted pneumatic tooling and workholding fixtures.
Workshop air bench for tools
Supplies a maintenance bench where operators adjust regulated pressure by the knob for impact wrenches, air ratchets and other shop tools.
Is the Airtac GFR Filter Regulator GFR300C15F1 the Right Unit?
Size 300 with a 1/2 in PT port is the mid-to-large step of the range; move to 400/600 for bigger ports and higher demand or to 200 for compact circuits. The blank filter position gives the 40 um standard element; specify W for the finer 5 um grade if downstream equipment needs it. The differential-pressure drain here discharges condensate automatically only when a sufficient pressure difference builds; automatic (A) gives continuous unattended drainage and manual (M) suits light, dry air with the wider 0.05-0.9 MPa regulation range. The F1 suffix sets the embedded square gauge on MPa scale; psi or bar scales are available. Choose G (BSPP) or NPT thread as an order option; the bracket is included by default. 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 GFR300C15F1 FAQ
There is no single rated flow figure for this unit; AirTAC publishes flow as performance curves against pressure. We do not quote numbers outside the datasheet, so send us your application's inlet pressure and flow requirement and we will confirm sizing and the datasheet on request.
A blank drain position is the differential-pressure drain: condensate is discharged automatically only when the pressure difference across the bowl reaches a set threshold. Specifying A selects fully automatic drainage and M selects a manual drain, which also widens the regulator range to 0.05-0.9 MPa (7-130 psi).
