Airtac GFR Filter Regulator GFR300C10C1
The AirTAC GFR Filter Regulator GFR300C10C1 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 GFR300C10C1
GFR300C10C1 is a genuine AirTAC G-series filter regulator: filtration and pressure regulation in a single body. This 300-size unit has a PT 3/8 in port, the standard 40 um filter element, and the default differential-pressure drain, which vents the PC (polycarbonate) bowl only when the pressure drop warrants it. The C1 gauge option adds an external round gauge with an MPa scale, so the setpoint is visible at the wall. Outlet pressure adjusts from 0.15 to 0.9 MPa (20 to 130 psi) with a maximum inlet of 1.0 MPa (145 psi); a mounting bracket is included and no check valve is fitted. Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part distributed for the US market. The G-series filter regulators span 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, three drain types, 40 um or 5 um (W) elements, and gauge choices including the embedded square type and this round MPa gauge. Flow is published as curves rather than a single rating, so we confirm datasheet figures against 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 GFR300C10C1 Is Used
Compressor room distribution drop
Set and monitor branch pressure at a compressor-room take-off: the round MPa gauge makes the setpoint visible and the differential-pressure drain suits a room that is visited daily.
Textile machine air supply
Condition the supply to loom and winding machine circuits: the 40 um element catches pipe scale and the regulator holds a steady pressure to the machine's jet and cylinder banks.
Panel air for a PLC-controlled sorting machine
Feed a control panel's pneumatic section where an operator reads pressure at the cabinet: the round gauge shows the setting at a glance without opening the enclosure.
Is the Airtac GFR Filter Regulator GFR300C10C1 the Right Unit?
Size the 300 body and its 3/8 in PT port between the compact 200 and the heavier 400/600 units, checking real demand against the flow curve, which we confirm on request. This code pairs the standard 40 um element with the differential-pressure drain - a set-and-forget choice for attended plant air - while automatic and manual drains are the other options. The C1 round gauge reads in MPa; psi (2) and bar (3) scales are catalogue alternatives. Thread is PT as the standard, with G and NPT available to order, and a bracket is included. If your circuit needs cleaner air, the W variant gives 5 um. Have us verify the datasheet curves against your pressure and 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 GFR300C10C1 FAQ
There is no single rated figure to quote: AirTAC publishes G-series performance as flow curves across the pressure range. Give us your operating pressure and required airflow and we will confirm the sizing from the datasheet on request.
The blank drain position is the differential-pressure type, fitted here, which purges the bowl as the element loads. A selects an automatic drain for unattended locations, and M selects a manual drain. Note the regulator range: automatic and differential drains give 0.15-0.9 MPa (20-130 psi), while manual drain widens the floor to 0.05 MPa (7 psi).
