Stop compromising doorway protection for style or power. This unheated industrial air curtain delivers targeted airflow across large openings, maintaining interior climate control while limiting the infiltration of dust, insects, and exhaust. Specialists designed the unit for 120-inch openings and heavy-duty environments, offering reliable performance in restaurants, hospitals, universities, and retail settings.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe air curtain exterior daily with a microfiber cloth and mild detergent; rinse and dry to remove grease and salts. Sanitize high-touch mounts, switches, and nearby chair backs and door handles with an EPA-approved surface disinfectant per label dwell time. Inspect motor housings and intake grills weekly; vacuum debris and clear crevices to deter pests. Regular cleaning prevents cross-contamination, supports health-code compliance, and preserves finish and service life.#@@#Additional Info#@#Mars Air Systems STD2120-3UD-OB air curtain fits 120" openings and protects 12 ft. high doors.#@@#General Info#@#Description #@#
Stop compromising doorway protection for style or power. This unheated industrial air curtain delivers targeted airflow across large openings, maintaining interior climate control while limiting the infiltration of dust, insects, and exhaust. Specialists designed the unit for 120-inch openings and heavy-duty environments, offering reliable performance in restaurants, hospitals, universities, and retail settings.
#@@# 3 Motor Design#@#
Three 1/2 HP motors create high-velocity airflow to span wide openings without reheating air, enabling effective separation between conditioned and outside air. Engineers selected the motors to deliver consistent performance at 208/230 volts and 60 hertz on a single-phase supply.
#@@# Wide Coverage#@#
Built to cover door widths from 120 inches to 131 inches, the assembly fits standard 10 to 12-foot openings and reduces drafts at peak traffic points. Installers find alignment straightforward thanks to a 12.13-inch cabinet height and a shallow 12.75-inch depth that preserves overhead clearance.
#@@# Durable Finish#@#
Fabricators applied an obsidian black powder coat to a galvanized steel cabinet to resist corrosion and abrasion in busy service areas. Facility managers receive a hardwearing exterior that maintains its appearance under frequent cleaning and handling.
#@@# Electrical Efficiency#@#
The unit operates at 1.57 kW, drawing 7.5 amps at nominal voltage, which balances airflow power and electrical load for commercial electrical infrastructure. Service teams appreciate the consistent single-phase operation that simplifies wiring and reduces installation complexity.
#@@# Safety Certification#@#
cETLus certification verifies compliance with North American safety standards, giving procurement officers documented assurance of electrical and construction safety. Inspectors and risk managers gain confidence from third-party testing and recognized certification markings.
