Stop losing conditioned air and increasing energy costs at busy entrances. This unheated industrial air curtain supplies a continuous, high-velocity airflow across a 144-inch opening to maintain indoor environmental control while accommodating heavy pedestrian and trolley traffic. Facility managers can rely on the performance of a galvanized steel cabinet finished in obsidian black powder coat, designed for demanding commercial applications.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces and high-touch zones (door handles, chair backs, menu covers, shakers) with a mild detergent, rinse, then sanitize using an EPA-registered sanitizer per label. Clean under shelves and booth crevices to remove crumbs and spills. Inspect and tighten fasteners on the 144" air curtain housing monthly. Dry all surfaces to prevent corrosion. Regular cleaning prevents germ transfer, shapes customer perception, deters pests, and preserves furnishings.#@@#Additional Info#@#Mars Air Systems N2144-3UD-OB air curtain fits 144" openings and delivers airflow with three 1/2 HP motors at 208-230v/60Hz/1-Ph, unheated galvanized cabinet, ETL sanitation listed, supports 8 Ft. opening height for commercial use.#@@#General Info#@#Description #@#
Stop losing conditioned air and increasing energy costs at busy entrances.

#@@# Motor Configuration#@#
Three 1/2 HP motors deliver concentrated airflow across wide openings, enabling consistent air separation that reduces infiltration and assists climate control systems. Each motor uses proven components for predictable service intervals and straightforward replacement when maintenance teams schedule downtime.
#@@# Electrical Compatibility#@#
Built for 208-230v, 60 Hz, single-phase power, the unit integrates with typical commercial electrical feeds without requiring bespoke wiring. Installers benefit from matching common voltage standards to simplify field commissioning and reduce labor time.
#@@# Coverage Width#@#
Engineered for openings from 144 inches to 155 inches, the curtain spans large doorways and loading bays without the need for multiple smaller units. Operations that face frequent door cycles maintain separation across the full width while personnel and carts pass through.
#@@# Mounting Depth#@#
A 13-inch cabinet depth provides a low profile that installs cleanly above door frames and beneath existing canopies, maximizing clearance and maintaining visual continuity. Technicians gain flexibility when coordinating the unit with overhead utilities and door operators.
#@@# Maximum Opening Height#@#
Designed to perform for openings up to 8 ft., the curtain maintains an effective air barrier for most commercial entryways and service doors. Building managers preserve indoor conditions in warehouses, kitchens, and retail entries where traffic causes frequent exchanges with exterior air.
