Airtac GFR Filter Regulator GFR300C15MJC1WK
The AirTAC Airtac GFR Filter Regulator GFR300C15MJC1WK 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 GFR300C15MJC1WK
The GFR300C15MJC1WK is an AirTAC GFR filter regulator: filtration and pressure regulation combined in one body, cleaning compressed air and holding downstream pressure at your set point. This PT1/2 configuration carries a manual drain (the bowl is bled by hand), a fine 5 um filter element for more sensitive downstream equipment, an external round gauge with an MPa scale, and a reverse (check) valve fitted so downstream pressure is held if supply fails. No mounting bracket is included under the J code.
This is a genuine AirTAC part in the 300 size of the G series, which runs from 200 to 600 with 1/8 in to 1 in ports in PT (standard), G or NPT thread. AirTAC publishes filter-regulator flow as curves rather than a single rated figure, so ask us and we will confirm flow and datasheet figures for your application on request. Max inlet pressure is 1.0 MPa (145 psi), the manual-drain regulator adjusts 0.05-0.9 MPa (7-130 psi), the polycarbonate bowl suits sizes 200-400, and operating temperature is -5 to 70 C.

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) | Mounting bracket included. |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 GFR300C15MJC1WK Is Used
CNC machining-center tool clamp
Feeding filtered, regulated air to the tool-clamping actuator on a CNC machining center; the 5 um element and check valve suit clamp circuits that must hold position if supply pressure drops.
Bottling-line gripper circuit
Conditioning the supply branch that feeds pick-and-place grippers on a bottling line, where the PT1/2 port serves a header running several small cylinders.
Conveyor divert-gate cylinders
Regulating air to diverter-gate cylinders on a warehouse conveyor, keeping gate shift pressure steady as demand on the line fluctuates.
Is the Airtac GFR Filter Regulator GFR300C15MJC1WK the Right Unit?
Step through GFR sizes 200, 300, 400 and 600 - each step gives a larger port (this unit is PT1/2) and more flow capacity, so size against your line demand. Drain choice is manual (as coded here), automatic, or the differential-pressure default; the manual-drain version regulates 0.05-0.9 MPa (7-130 psi). Filter grade is 40 um standard or 5 um with the W option, which this unit carries. The gauge here is the external round type with MPa scale; square gauges and psi/bar scales are alternatives. Thread is PT as standard with G and NPT orderable, and a bracket is optional (not included under J). Because flow is published as curves rather than a single rating, 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 GFR300C15MJC1WK FAQ
AirTAC publishes GFR flow as characteristic curves, not as a single rated figure, so we do not quote a number here. Send us your line demand and we will confirm the flow and sizing from the datasheet on request.
The M code fits a manual drain: the bowl is bled by hand on a schedule. Automatic and differential-pressure drains are available in the same series; note the regulator adjust range differs - manual drain 0.05-0.9 MPa, automatic and differential-pressure drain 0.15-0.9 MPa.
