LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces with a mild detergent and soft cloth; use a non-abrasive sanitizer on high-touch zones such as control panels and housing edges. Rinse with clean water and dry immediately to prevent corrosion. Inspect mounting and electrical conduit monthly; tighten fasteners and remove debris under and above the unit. Regular cleaning prevents contamination transfer, supports health-code compliance, deters pests, and preserves finish and function.#@@#Additional Info#@#Mars Air Systems N284-2UH-OB air curtain fits 84" openings and covers 8 ft. using two 1/2 HP motors at 460v/60/3-Ph; unheated galvanized steel cabinet with black powder coat, ETL listed, 125 pounds, designed for commercial airflow control.#@@#General Info#@#Description #@#
Stop sacrificing control for convenience. This unheated industrial air curtain delivers targeted airflow for wide doorways, maintains internal environments, and reduces infiltration without relying on heat, offering reliable performance in high-use settings. Designed for commercial installations that demand consistent operation, this unit combines robust construction with serviceable components to minimize downtime and simplify maintenance.
#@@# Motor Configuration#@#
Two 1/2 HP motors power the unit, providing sustained air velocity for openings ranging from 84 inches to 95 inches. Each motor delivers focused thrust to span door heights up to 8 feet, enabling effective separation between interior and exterior conditions.
#@@# Electrical Rating#@#
The assembly connects to 460 volts at 60 hertz and operates on 3-phase power, matching common industrial distribution systems. The specified voltage and phase support stable motor operation and reduce electrical stress under continuous loads.
#@@# Cabinet Finish#@#
A galvanized steel cabinet with an obsidian black powder coat resists corrosion and withstands frequent cleaning cycles. The finish provides a professional appearance while protecting internal components in demanding environments.
#@@# Airflow Coverage#@#
Engineered for an 84-inch door width, the unit generates a concentrated airstream that minimizes drafts and particulate entry. The design suits high-traffic entrances in restaurants, hospitals, campuses, and hospitality venues where control of air exchange is essential.
#@@# Compliance Listing#@#
ETL listing verifies the unit meets relevant safety standards for electrical and mechanical construction. Facility managers can document adherence to codes and streamline approvals during installation.
#@@# Serviceability Design#@#
Modular access to motors and internal components simplifies routine inspection and replacement, reducing labor time during maintenance.
