Stop sacrificing doorway control for energy efficiency. This industrial air curtain delivers focused airflow and reliable performance for 36-inch openings, maintaining conditioned zones while minimizing infiltration and pest entry. Designed for continuous operation in commercial settings, the unit mounts over doors up to 8 feet high and operates on 208-230 volts, 3-phase power for stable duty cycles.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces and outlet grille daily with a microfiber cloth and mild detergent solution to remove grease and crumbs. Use a soft brush to clear motor inlet screens weekly. Rinse cloths, change solution after heavy soil, and dry metal surfaces to prevent corrosion. Clean high-touch zones such as door frames and switchplates to prevent contamination transfer and support health-code compliance and pest deterrence.#@@#Additional Info#@#Mars Air Systems N236-1UG-OB air curtain fits 36" wide doors and protects 8 Ft. openings with three 1/2 HP motors totaling 1.5 HP, unheated galvanized steel cabinet with obsidian black powder coat, 208/230v 60 Hz 3-Ph power, ETL listed, 60 pounds.#@@#General Info#@#Description #@#
Stop sacrificing doorway control for energy efficiency. This industrial air curtain delivers focused airflow and reliable performance for 36-inch openings, maintaining conditioned zones while minimizing infiltration and pest entry. Designed for continuous operation in commercial settings, the unit mounts over doors up to 8 feet high and operates on 208-230 volts, 3-phase power for stable duty cycles.
#@@# Motor Configuration#@#
Three 1/2 HP motors provide layered airflow to ensure uniform coverage across the full 36-39 inch width. Each motor runs on 208-230 volts at 60 hertz and supports sustained operation in high-traffic environments.
#@@# Unheated Design#@#
The unheated configuration eliminates burner plumbing and heat controls, reducing maintenance points and lowering installation complexity. Facilities that require non-thermal air separation gain a durable solution without added energy for heating.
#@@# Durable Finish#@#
Obsidian black powder coat resists corrosion and conceals wear in demanding locations such as loading docks and kitchen entrances. The galvanized steel cabinet underneath provides structural integrity while the finish simplifies cleaning.
#@@# Coverage Performance#@#
Engineers sized the unit for doors up to 8 feet tall, producing a consistent air stream that minimizes conditioned air loss and prevents contaminants from entering. Installers receive predictable performance metrics for building envelope preservation.
#@@# Safety and Compliance#@#
ETL listing confirms evaluation to recognized safety standards, supporting code inspections and facility compliance workflows. The electrical design aligns with three-phase distribution common in commercial districts.
#@@# Serviceability Features#@#
Technicians access internal components through serviceable panels, and the simple motor layout reduces downtime during routine maintenance. The compact 13-inch depth allows installation in constrained header spaces while preserving service access.
