Engineered to control airflow and maintain interior conditions in high-traffic openings, this unheated industrial air curtain delivers targeted performance for 48-inch doorways while minimizing energy input and maintenance demands. Designed for continuous operation, the unit uses a single 1/2 HP motor and a 460-volt 3-Ph electrical supply to produce a stable air stream that reduces the infiltration of dust, insects, and conditioned air loss. Certified to cETLus standards, the assembly mounts within the available 12.75-inch cabinet depth and fits door widths between 48 inches and 59 inches, supporting openings up to 12 feet in height.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior housing and inlet grille daily with a mild detergent and soft cloth; rinse and dry. Sanitize high-touch controls and mounting brackets with an EPA-approved disinfectant per label. Inspect for debris under shelves and above doorways weekly; remove buildup to deter pests. Tighten fasteners monthly and record actions for CSA compliance. Regular cleaning prevents cross-contamination and supports positive customer perception.#@@#Additional Info#@#Mars Air Systems STD248-1UH-OB unheated air curtain fits 48" openings, creating a high-velocity airstream; 460v, 3-Ph power with (1) 1/2 HP motor delivers 550 watts at 0.8 amps, galvanized cabinet with black powder coat, cETLus certified, 70 lbs.#@@#General Info#@#Description #@#
Engineered to control airflow and maintain interior conditions in high-traffic openings, this unheated industrial air curtain delivers targeted performance for 48-inch doorways while minimizing energy input and maintenance demands. Designed for continuous operation, the unit uses a single 1/2 HP motor and a 460-volt 3-Ph electrical supply to produce a stable air stream that reduces the infiltration of dust, insects, and conditioned air loss. Certified to cETLus standards, the assembly mounts within the available 12.75-inch cabinet depth and fits door widths between 48 inches and 59 inches, supporting openings up to 12 feet in height.
#@@# Motor Efficiency#@#
The unit employs one 1/2 HP motor driven at 460 volts and 60 hertz, yielding reliable airflow while drawing only 0.8 amps at 550 watts. Facility managers gain consistent performance with modest electrical demand, lowering operating costs compared with larger multi-motor systems.
#@@# Durable Finish#@#
Manufactured with a galvanized steel cabinet finished in black powder coat, the housing resists corrosion and surface wear in commercial environments. Maintenance crews benefit from a robust exterior that simplifies cleaning and preserves appearance under frequent use.
#@@# Compact Footprint#@#
The shallow 12.75-inch depth allows installation in tight canopy spaces and above doorframes without obstructing clearance. Engineers can integrate the unit into existing storefronts or service entries without major structural modifications.
#@@# Performance Range#@#
Designed for door widths from 48 inches up to 59 inches and maximum opening heights of 12 feet, the curtain produces a focused air seal across common commercial thresholds. Operators obtain measurable reductions in air exchange and particulate ingress for kitchens, retail, or service areas.
#@@# Safety Certification#@#
Tested and certified to cETLus standards, the assembly meets recognized electrical and safety requirements for North American installations.
