Model Overview
L3E (exhaust) and L3S (supply) are high capacity wall mounted belt driven propeller fans rated from 35,000 to 85,000, with static pressure capability up to 1" W.G. Their primary application is the exhaust of large volumes of air at relatively moderate static pressure from commercial, industrial and agricultural buildings such as manufacturing and assembly plants, warehouses, foundries, mills, boiler rooms and equipment rooms.
Wall mounting provides an easy and economical installation. Belt driven fans provide large volumes of air at low fan speed and low noise levels and afford quick, easy performance adjustments. All required accessories are available with Model L.
See Model L - Construction Level 1, or Construction Level 2, for lower static pressures and lighter duty requirements which are more economical.
