GENERAL
Marley air curtains produce a wall of continuously flowing air that acts as a thermal barrier against outside air and flying insects.
These air curtains maintain interior conditioned temperature and prevent heated or cooled air from escaping through open door-
ways. They reduce humidity and loss of cold air when used over freezer and cooler doors. High traffic area doors can be left open,
eliminating wear and nuisance of opening and closing automatic and manual doors used over service entrances, access doors, etc.
Air curtains provide protection against insects, dust, odor, fumes and other contaminants.
