Built for continuous operation in high-traffic entrances, this industrial air curtain delivers consistent airflow and precise installation dimensions to protect indoor environments while reducing energy loss. The unit mounts across openings up to twelve feet high and spans a nominal 144 inches, providing a focused air stream driven by three robust motors. The cabinet is constructed from galvanized steel with an obsidian black powder coat, ensuring resistance to corrosion and preserving its appearance in demanding settings.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior cabinet and louvers with mild detergent and warm water; rinse and dry to prevent corrosion. Clean intake and discharge grilles weekly with a soft brush or vacuum to remove dust that reduces airflow. Inspect mounting hardware and tighten fasteners monthly. For greasy buildup use a degreaser safe for powder coat; test inconspicuous area first. Regular cleaning prevents contamination transfer at high-touch zones and supports health-code compliance.#@@#Additional Info#@#Mars Air Systems STD2144-3UH-OB air curtain fits 144" openings, delivering airflow with three 1/2 HP motors at 460v/60Hz/3-Ph, drawing 2.4 amps.#@@#General Info#@#Description #@#
Built for continuous operation in high-traffic entrances, this industrial air curtain delivers consistent airflow and precise installation dimensions to protect indoor environments while reducing energy loss. The unit mounts across openings up to twelve feet high and spans a nominal 144 inches, providing a focused air stream driven by three robust motors. The cabinet is constructed from galvanized steel with an obsidian black powder coat, ensuring resistance to corrosion and preserving its appearance in demanding settings.
#@@# Motor Trio#@#
Three 1/2 HP motors drive the air stream, supplying reliable thrust for sustained traffic flow and consistent separation between conditioned and unconditioned zones. Each motor connects to a 460 volts, 60 hertz, 3-Ph supply and draws 2.4 amps, enabling predictable electrical planning and simplified service.
#@@# Unheated Design#@#
This configuration omits heat elements and prioritizes airflow efficiency, lowering electrical demand to 1.65 kW while maintaining effective thermal separation in moderate climates. Facilities that do not require warmed output can reduce operating costs and simplify maintenance through fewer components.
#@@# Compact Depth#@#
A 12.75-inch cabinet depth enables installation in tight headroom conditions while preserving the required volume for motor and fan assembly. Contractors gain flexibility for retrofit projects where shallow mounting envelopes limit equipment choices.
#@@# Installation Fit#@#
Engineers can place the unit across door widths from 144 inches to 155 inches and still achieve uniform coverage, reducing cold drafts and pest ingress. The model accommodates openings up to 12 feet high, ensuring compatibility with most commercial entry configurations.
#@@# Durable Finish#@#
The obsidian black powder coat over galvanized steel provides surface corrosion resistance and a neutral aesthetic that integrates seamlessly with professional interiors.
