Stop compromising doorway control for energy loss. This unheated air curtain delivers focused airflow across wide openings to maintain interior conditions while reducing infiltration and operational strain for staff and HVAC systems. Designed for heavy-use settings, the unit mounts over 84-inch openings and operates on three-phase power to sustain continuous performance in commercial environments.
LongDescription#@#NA#@@#Cleaning Instructions#@#Use a damp microfiber with mild detergent to wipe high-touch zones: menu covers, shakers, chair backs, door handles, and booth crevices. Rinse with clean water and dry immediately. Sanitize weekly with an approved disinfectant to reduce Norovirus and cold-virus transfer. Inspect under shelves and around serving stations for spills; remove debris to deter pests. Regular cleaning preserves furnishings, supports health-code compliance, and maintains guest perception.#@@#Additional Info#@#Mars Air Systems STD284-2UG-OB air curtain fits 84" openings, unheated with a galvanized steel cabinet and obsidian black powder coat finish, (2) 1/2 HP motors, 208-230v/60Hz/3-Ph, 1.02 kW, 3.6/3.2 amps, cETLus certified, 125 pounds weight.#@@#General Info#@#Description #@#
Stop compromising doorway control for energy loss. This unheated air curtain delivers focused airflow across wide openings to maintain interior conditions while reducing infiltration and operational strain for staff and HVAC systems. Designed for heavy-use settings, the unit mounts over 84-inch openings and operates on three-phase power to sustain continuous performance in commercial environments.
#@@# Motor Configuration#@#
Two 1/2 HP motors provide balanced thrust across the full width, producing consistent air velocity that blocks drafts and minimizes heat transfer. Each motor runs on 208-230 volts and draws 3.6/3.2 amps, enabling stable operation on three-phase circuits.
#@@# Wide Coverage#@#
Engineers sized the cabinet to span 84-inch openings with compatibility up to 95 inches, ensuring uniform protection for large doors and service entrances. The broad footprint reduces the need for multiple units and simplifies installation planning.
#@@# Energy Profile#@#
The assembly consumes 1.02 kW under rated conditions, allowing facilities to project electrical demand and integrate the unit into power budgets accurately. Technician teams benefit from clear voltage and ampere specifications for load balancing.
#@@# Durable Cabinet Finish#@#
Fabricators constructed the housing from galvanized steel with an obsidian black powder coat to resist corrosion and surface wear in high-traffic zones. Maintenance crews can clean the exterior quickly while preserving a professional appearance.
#@@# Safety and Compliance#@#
Manufacturers certifying the unit as cETLus confirm compliance with North American electrical and safety standards, supporting adoption in schools, hospitals, and hospitality operations. Facilities staff receive reduced regulatory friction during procurement.
#@@# Installation Parameters#@#
Designers limit maximum opening height to 12 ft.
