Airtac GFR Filter Regulator GFR300C10MF3
The AirTAC GFR Filter Regulator GFR300C10MF3 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 GFR300C10MF3
The GFR300C10MF3 is an AirTAC GFR series filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This 300-size unit is ported PT3/8 with PT thread as standard. The M in the code selects a manual drain, so the bowl is emptied by hand as part of your maintenance routine. The element is the standard 40 um grade, and the F3 finish selects the embedded square pressure gauge with a bar scale.
This is a genuine AirTAC part. G-series filter regulators come in 200, 300, 400 and 600 sizes covering 1/8 in to 1 in ports, with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) elements, square or round gauges, optional mounting brackets and G (BSPP) or NPT thread options. AirTAC publishes flow as curves rather than a single rating, so we confirm datasheet and flow figures 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.

| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| C1 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |

| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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 GFR300C10MF3 Is Used
Pneumatic press clamp circuit
Filtered, regulated supply for the clamp cylinders on a stamping or forming press, holding the operator-set clamp pressure through each cycle.
Packaging machine valve islands
Point-of-use prep feeding the valve islands on carton form-fill-seal and case-packing machines, keeping water and debris in shop air away from the solenoid valves.
Air-assisted spray line
Bench or drop-point prep at a spray booth or air-assisted coating line, letting the operator set line pressure at the gun and drain the bowl during clean-down.
Is the Airtac GFR Filter Regulator GFR300C10MF3 the Right Unit?
Pick the 300 size when your air demand outgrows the 200 body and the 3/8 in port fits the supply line - match size and port to actual flow, not habit. This manual-drain (M) version has a regulator setting range of 0.05-0.9 MPa (7-130 psi), wider at the low end than the 0.15-0.9 MPa (20-130 psi) of automatic and differential-pressure drain versions. The 40 um element suits general shop air; if downstream valves need finer protection, order the W variant with the 5 um element. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and the bracket is included on this configuration.
Honest routing on sizing: AirTAC publishes flow as curves, not a single rating, so ask us to confirm the GFR300 against your line pressure and air consumption before you order.
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 GFR300C10MF3 FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your inlet pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet on request before you order.
The M code means the bowl is emptied by hand, which suits accessible mounting points and planned-maintenance routines. If you want the bowl to discharge on its own, order the A (automatic) version, or use the standard differential-pressure drain. Note that with a manual drain the regulator setting range is 0.05-0.9 MPa (7-130 psi), while automatic and differential-pressure versions start at 0.15 MPa (20 psi).
