LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe air curtain cabinet and grills daily with mild detergent and a soft cloth, then rinse and dry. Remove dust from fan blades and motor housing weekly using compressed air or a soft brush. Sanitize high-touch controls and nearby door frames with EPA-approved surface sanitizer per label. Inspect mounting hardware monthly and tighten as needed. Regular cleaning prevents cross-contamination, shapes customer perception, ensures health-code compliance, deters pests, and preserves finish.#@@#Additional Info#@#Mars Air Systems N236-1UD-OB air curtain fits 36" doors, providing unheated separation with three 1/2 HP motors at 208-230v/60Hz, 1-Ph power; galvanized steel cabinet with black powder coat, ETL listed, supports openings to 8 Ft.#@@#General Info#@#Description #@#
Built to protect entrances and maintain indoor climate control, this industrial air curtain combines robust airflow with commercial-grade construction to minimize infiltration at high-traffic openings. Designed for 36-inch openings, the unit operates on 208-230V single-phase power, delivering consistent performance for retail, hospitality, institutional, and food service environments. Its field-proven motor configuration and ETL sanitation listing ensure reliable operation and compliance with safety codes.
#@@# Motor Configuration#@#
Three 1/2 HP motors provide concentrated airflow across openings ranging from 36 to 39 inches, allowing the unit to maintain a consistent air barrier through frequent door cycles. Installers appreciate the balanced motor layout, which simplifies wiring to a 208-230V single-phase supply, while technicians benefit from accessible service points.
