Airtac GFR Filter Regulator GFR300C10MC1K
The AirTAC GFR Filter Regulator GFR300C10MC1K 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 GFR300C10MC1K
The GFR300C10MC1K is an AirTAC G-series filter regulator with a check (reverse) valve fitted: water and particulate filtration plus downstream pressure regulation in one body, with a drain bowl but no lubricator. This 300-size configuration carries 3/8 in PT ports, a manual drain, the standard 40 um filter element and a round external pressure gauge on an MPa scale. The K option adds a check valve so downstream air does not flow back through the unit. Maximum working pressure is 1.0 MPa (145 psi) and the regulating range with manual drain is 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C (non-freezing); the 300-size bowl is polycarbonate (PC).
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, with 40 um standard or 5 um (W) elements, differential-pressure, automatic or manual drains, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT thread options, and bracket or no-bracket mounting. AirTAC publishes flow data as curves rather than a single rating, so we confirm the 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.

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 GFR300C10MC1K Is Used
Pneumatic press with retained setpoint
Feeding a pneumatic press valve bank, the filter-regulator section cleans the shop air and sets cylinder pressure, while the check valve holds the regulated circuit against backflow from the downstream side.
Machine-tool air drop isolation
Installed on an individual machine's air drop, it conditions the supply to the tool's pneumatic circuits and, with the fitted check valve, stops air from neighbouring branches pushing back through the set when the main is cycled.
Clamp and fixture circuits on jigs
On welded jigs and fixtures using pneumatic swing clamps, it filters and regulates the 3/8 in feed; the check valve helps keep the clamped circuit from losing its set through the supply side during upstream work.
Is the Airtac GFR Filter Regulator GFR300C10MC1K the Right Unit?
Size 300 with 3/8 in PT ports suits lines plumbed and consuming air at that level; step down to 200 or up to 400/600 to change port and flow capacity. The manual drain means condensate is bled by hand; automatic or differential-pressure drains are orderable alternatives. The 40 um element is standard and a 5 um (W) option exists. The K code fits a check valve - useful where a backflow path through the unit must be prevented - and gauge codes set round or square faces with MPa, psi or bar scales. Trailing G or T change the thread from PT to G (BSPP) or NPT, and J omits the bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR300C10MC1K FAQ
The K code fits a reverse (check) valve in the unit, so air cannot flow backwards through it from the downstream side. Without the K, the same filter regulator has no check valve. Flow capacity itself is published by AirTAC as curves, not a single rating - we confirm the datasheet figures on request.
No. The M code is a manual drain: an operator periodically bleeds condensate from the polycarbonate bowl. If unattended drainage is preferred, the identical unit can be ordered with an automatic (A) or differential-pressure drain code instead.
