Engineered Airflow

The M-1811 (Ultra) Air Cooler Blade – 18 Inch is a 4-leaf blade at 18″/460mm, set to a 125mm pitch. That geometry moves a high volume of air at low rotational noise — the difference between a cooler that throws air across a room and one that only stirs it.

Material and Load

Moulded in High Grade PP Glass-Filled for high impact resistance and dimensional stability at summer cabinet temperatures. The balanced hub minimises motor load, so the winding runs cooler and the bearing lasts longer.

Fitment and Supply

Fits 32MM shafts on H Frame motors. Supplied in systematic packaging at 12 pieces per box for clean warehouse handling and low transit damage.
