Stop losing energy control at exterior openings. This heavy-duty air curtain delivers continuous, directional airflow for 108-inch openings, reducing infiltration, maintaining interior climate, and supporting sanitation protocols while operating on 208/230 volts single-phase power. Facility managers benefit from consistent performance thanks to a three-motor assembly housed in an obsidian black powder-coated cabinet designed for demanding commercial environments.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe the air curtain cabinet and visible fasteners with a mild detergent and soft cloth, then rinse and dry. Disinfect high-touch zones like door handles, chair backs, and menu covers using EPA-approved sanitizer; follow contact time on label. Clean under shelves and booth crevices to remove crumbs and spills. Inspect for corrosion and tighten mounting hardware. Regular cleaning prevents contamination, deters pests, preserves finish and supports health-code compliance.#@@#Additional Info#@#Mars Air Systems STD2108-3UD-OB air curtain fits 108" doors and covers openings to 12 ft, using three 1/2 HP motors at 208/230 volts, 60 Hz, 1-Ph, drawing 1.5 amps; galvanized cabinet with black powder coat, cETLus certified, 175 pounds.#@@#General Info#@#Description #@#
Stop losing energy control at exterior openings. This heavy-duty air curtain delivers continuous, directional airflow for 108-inch openings, reducing infiltration, maintaining interior climate, and supporting sanitation protocols while operating on 208/230 volts single-phase power. Facility managers benefit from consistent performance thanks to a three-motor assembly housed in an obsidian black powder-coated cabinet designed for demanding commercial environments.
#@@# Motors And Drive#@#
Three 1/2 HP motors provide concentrated airflow and redundancy for high duty cycles. Each motor operates on 208/230 volts at 60 hertz and draws a combined 1.5 amps, enabling sustained operation while keeping electrical demand predictable for building systems.
#@@# Wide Coverage#@#
Engineered for doors between 108 and 119 inches, the curtain produces a continuous air stream across a full 12-foot opening to limit air exchange and pest ingress. Installers receive clear mounting dimensions and a profile depth of 12.75 inches to plan clearances and mounting brackets effectively.
#@@# Unheated Design#@#
The unheated configuration eliminates heating elements to reduce electrical load and simplify service procedures. Operators relying on mechanical ventilation can maintain conditioned air without additional heat inputs, reducing energy complexity in multi-zone facilities.
#@@# Durable Finish#@#
The obsidian black powder coat protects the galvanized steel cabinet from surface wear and corrosion in high-traffic areas. Maintenance teams will appreciate a finish that withstands frequent cleaning and resists chipping during routine handling.
#@@# Certifications And Safety#@#
cETLus certification verifies compliance with North American safety and performance standards for electrical equipment. Facility compliance officers can document regulatory conformance during inspections and risk assessments.
#@@#Delivery Details#@#
• Please ensure to handle the product with utmost care.
• Check if the product you have received has all the essential parts and accessories.
• Make sure to examine the product for damage before signing the delivery receipt.
• Contact customer service for delivery concerns.
• Delivery times may vary based on location.#@@#deliverynotes#@#NA#@@#Maintenance Guide#@#Inspect the air curtain monthly and clear debris from inlet and outlet grilles to maintain specified airflow. Tighten mounting hardware and verify alignment with the 108" opening to prevent air bypass. Lubricate motor bearings per manufacturer schedule and replace worn belts; follow CSA-compliant procedures. Measure voltage at 208-230 volts and confirm 7.5 amp draw under normal load. Test operation after maintenance and log actions for facility records.
