Built to control airflow for busy entrances, this industrial air curtain delivers powerful, reliable performance while minimizing energy transfer between indoor and outdoor spaces. Designed for 48-inch openings, the unit mounts above doors and generates a continuous high-velocity airstream that reduces infiltration and helps maintain conditioned room temperatures. Engineers specified rugged galvanized steel construction with an obsidian black powder coat to withstand commercial use and simplify cleaning.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe chair backs, menu covers, shakers, door handles, booths, and rails with a neutral detergent and soft cloth; rinse and dry. Disinfect high-touch zones using EPA-registered sanitizer per label dilution and contact time. Clean under shelves and booth crevices weekly to remove crumbs and grease. Inspect surfaces daily and repair damaged finishes to prevent material degradation and pest attraction. Regular cleaning protects customers, staff, and compliance.#@@#Additional Info#@#Mars Air Systems STD248-1UA-OB air curtain offers 48" coverage for unheated openings. It has a 1/2 HP motor, 115v/60/1-ph supply, 5.1 amps, and 550 watts.#@@#General Info#@#Description #@#
Built to control airflow for busy entrances, this industrial air curtain delivers powerful, reliable performance while minimizing energy transfer between indoor and outdoor spaces.

#@@# Airflow Control#@#
This unit produces a focused air barrier sized for 48-inch openings to reduce drafts and contamination transfer across thresholds. Field-adjustable mounting supports openings from 48 inches to 59 inches and accommodates door heights up to 12 feet, enabling site-specific alignment for consistent performance.
#@@# Motor Capacity#@#
A single 1/2 HP motor provides the torque required for sustained operation in high-traffic environments. Rated at 550 watts and drawing 5.1 amps on 115v 60 Hz 1-Ph power, the motor balances airflow output with manageable electrical demand for most service panels.
#@@# Durable Cabinetry#@#
Fabricators used galvanized steel with a black powder coat finish to resist corrosion and surface wear in busy facilities. Cleanability simplifies routine maintenance and extends service life under frequent cycling and indoor environmental exposure.
#@@# Safety Certification#@#
The assembly carries cETLus certification, validating electrical safety and compliance with North American standards. Inspectors and facility managers benefit from documented third-party testing that supports code compliance and insurance requirements.
#@@# Installation Flexibility#@#
Engineers sized the unit for simple overhead mounting and integration with standard door headers, minimizing retrofit complexity. Compact depth at 12.75 inches reduces projection into entryways while maintaining sufficient fan and motor clearance for airflow efficiency.
