Lifebreath Filters for Energy-Efficient Ventilation Hoods

Page 19

Specifications

Model CAF-U-L2A-48-P16

Core Ventilation system has patented aluminum heat recovery core (standard) or an enthalpic energy recovery core (optional) for energy-efficient ventilation. Enthalpic cores are recommended for

regions where the temperature does not drop below 25˚F (-4˚C).

Filters

Case

Washable air filters in exhaust and supply air streams of ventilation section, 1" pleated in return plenum side.

Prepainted galvanized steel for superior corrosion resistance.
