Airtac GFR Filter Regulator GFR300C15MF1W
The AirTAC Airtac GFR Filter Regulator GFR300C15MF1W 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 GFR300C15MF1W
GFR300C15MF1W is an AirTAC GFR300 filter regulator: filtering and pressure regulation combined in one body, sized 300 with a 1/2 in PT port. The W code fits the finer 5 um filter element instead of the standard 40 um grade, and this configuration also carries a manual drain and a square pressure gauge on an MPa scale. It runs on compressed air only, from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi) and a regulator setting range of 0.05-0.9 MPa (7-130 psi) on this manual-drain version. The 300-size bowl is polycarbonate; only the 600 size carries an aluminium bowl.
This is a genuine AirTAC part sold by a distributor. The G series covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and drain types, filter grades, gauge styles and G (BSPP) or NPT threads are catalogue options. Flow is published as curves rather than a single rating, so we confirm the datasheet and full flow curve for your application 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 GFR300C15MF1W Is Used
Clean dry air to laboratory analytical instruments
The 5 um element removes finer particles ahead of sensitive instrument pneumatics, with pressure set and read on the square gauge.
Film sealing bars on a tray-wrapper packaging machine
Regulated, finely filtered air drives the sealing and clamping cylinders, with the bowl drained at each sanitation stop.
Air circuit for a test rig in an R&D workshop
A stable regulated supply at the 1/2 in port supports repeatable test conditions, and the 5 um grade protects prototype tooling and valves.
Is the Airtac GFR Filter Regulator GFR300C15MF1W the Right Unit?
Size 300 with a 1/2 in PT port is the mid-range choice in the G series; move up to 400 or 600 for larger ports and demand, or down to 200 for compact circuits. The W code selects the 5 um element - the right call when downstream equipment is sensitive to fine particles; the standard grade is 40 um. Manual drain keeps things simple but requires periodic opening of the bowl drain, so specify the automatic-drain code for unattended installations. The square MPa gauge is fitted, and PT is the standard thread with G (BSPP) and NPT available as ordered options. A bracket is included; J-coded versions omit it. Flow is published as curves, not one number - ask us to confirm sizing against your demand 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 GFR300C15MF1W FAQ
AirTAC publishes flow for the GFR300 series as curves rather than a single rated figure, so we do not state one number. Share your working pressure and required flow and we will confirm the datasheet and full flow curve for this 1/2 in port model on request before you order.
No. W only selects the 5 um element in place of the standard 40 um grade. Function, drain type, gauge, port and thread stay as specified here: filter regulator, manual drain, square MPa gauge, 1/2 in PT port. There is no lubricator in any GFR model - add a separate lubricator if oil mist is needed.
