The Mars LPN272-1UA-OB/99-014 72" unheated air curtain is designed to meet the hygiene and efficiency needs of commercial kitchens. Unlike traditional plastic strip curtains, this low-profile air curtain effectively blocks flying insects, prevents conditioned air loss, and maintains a 40° sweep without raising room temperature—perfect for food prep areas where cleanliness is critical. Its automatic on/off function (activated by the included 99-014 door limit switch) saves energy by turning off when the door is closed, reducing operational costs while ensuring continuous protection. The obsidian black, corrosion-resistant electrostatic polyurethane coating extends durability, making it a long-lasting solution for high-traffic restaurant environments.
