Stop sacrificing doorway control for appearance or cost. This industrial-grade air curtain delivers focused airflow and proven performance across high-traffic openings, protecting interior environments while minimizing energy transfer through unheated operation. Shipments include a robust galvanized cabinet with an obsidian black powder coat finish and multiple motorized sections engineered for wide commercial doors.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe high-touch zones like menu covers, shakers, chair backs, and door handles with a detergent solution, then disinfect with an EPA-registered sanitizer following label contact time. Use microfiber cloths and replace when soiled. Vacuum and remove crumbs around booths and under shelves daily to deter pests. Inspect surfaces weekly for damage and polish wood or vinyl to extend service life. Regular cleaning prevents contamination, shapes customer perception, and supports health-code compliance.#@@#Additional Info#@#Mars Air Systems STD2144-3UD-OB air curtain fits 144" openings and delivers a 1.65 kW airstream using three 1/2 HP motors at 208-230v, 60 Hz, 1-Ph; galvanized steel cabinet, cETLus certified, 200 pounds, unheated design.#@@#General Info#@#Description #@#
Stop sacrificing doorway control for appearance or cost. This industrial-grade air curtain delivers focused airflow and proven performance across high-traffic openings, protecting interior environments while minimizing energy transfer through unheated operation. Shipments include a robust galvanized cabinet with an obsidian black powder coat finish and multiple motorized sections engineered for wide commercial doors.
#@@# Three Motors#@#
Three independent 1/2 HP motors provide concentrated air projection for the full 144-inch width, enabling consistent coverage across large openings. Operators will reduce infiltration and maintain interior conditions because each motor runs on 208-230 volts and 60 hertz with a 1-Ph power configuration.
#@@# Wide Coverage#@#
Designed for openings between 144 inches and 155 inches, the unit secures doorways up to 12 ft high with a continuous airstream across the entire span. Facility managers will find that the extended width prevents pressure imbalances that cause drafts and temperature fluctuations.
#@@# Unheated Operation#@#
The unheated configuration eliminates heating element maintenance and reduces electrical draw while still delivering effective air separation. Building teams will lower energy consumption when climate control remains intact without heat output.
#@@# Durable Cabinet#@#
Constructed from galvanized steel and finished with an obsidian black powder coat, the cabinet resists corrosion and holds up under daily use in commercial spaces. Maintenance personnel will appreciate the rugged surface that withstands cleaning and reduces long-term repair cycles.
#@@# Electrical Specification#@#
The unit operates at 208-230 volts, draws 7.5 amps, and consumes 1.65 kW under rated conditions, matching common commercial electrical panels. Electricians will plan installations quickly since the single-phase wiring and amp rating simplify circuit sizing and breaker selection.

Tighten mounting hardware and check electrical connections for wear; replace damaged wiring per CSA guidelines. Clean fan blades with a soft brush and low-pressure air; avoid solvents that degrade the powder coat. Verify motor amperage with a clamp meter and compare to 7.5-amp rating. Lubricate bearings quarterly if specified by Mars Air Systems.
