LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces with a microfiber cloth and neutral detergent; rinse and dry. Sanitize high-touch zones like control panels and door frames with an EPA-approved disinfectant following label dwell time. Vacuum intake grilles monthly and inspect motors for debris; remove buildup to prevent pest attraction. Tighten hardware quarterly. Regular cleaning prevents cross-contamination of hands and items, maintains inspection compliance, and preserves finish and function.#@@#Additional Info#@#Mars Air Systems STD2120-3UA-OB air curtain fits 120" doors, covering up to 12 ft. height.

#@@# Three Motor Array#@#
Three motors drive the airstream to maintain uniform coverage across wide openings. Each motor provides 1/2 HP output, enabling the unit to sustain flow velocity for doors up to 120 inches wide without overloading a single drive component.
#@@# High Voltage Compatibility#@#
The product operates on 115 volts at 60 hertz and a single-phase supply, allowing seamless integration with standard electrical service commonly found in commercial kitchens, retail entries, and industrial loading bays. Installers will note the 15.3 amp draw for circuit planning and breakers.
#@@# Wide Door Coverage#@#
Designed for openings from 120 inches to 131 inches, the curtain creates a continuous air barrier across expansive thresholds. Facility planners can rely on the specified widths to protect interior climate control and reduce contaminant entry.
#@@# Slim Profile Cabinet#@#
A 12.75-inch cabinet depth allows placement within shallow door headers while preserving full airflow performance. Technicians will find the galvanized steel core with an obsidian black powder coat finish resists corrosion and aligns with professional finishes.
#@@# Unheated Standard Operation#@#
The unheated configuration reduces electrical complexity and eliminates heating elements, lowering maintenance points while providing effective air separation for temperate climates.
