Stop losing conditioned indoor air to open doorways. This industrial air curtain delivers a concentrated airstream across a 108-inch opening to reduce infiltration, maintain indoor climate control, and lower HVAC load while operating on 208/230 volts with three 1/2 HP motors for sustained performance.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior cabinet and inlet grille daily with mild detergent and soft cloth; rinse and dry. Remove grille monthly, vacuum fan housing and motor vents; use compressed air at low pressure to clear dust. Sanitize high-touch surfaces (door handles, chair backs, menu covers) with EPA-approved disinfectant per label. Inspect seals and mounting bolts quarterly; tighten as needed. Regular cleaning prevents cross-contamination, pest attraction, and maintains appearance and compliance.#@@#Additional Info#@#Mars Air Systems STD2108-3UG-OB air curtain fits 108" door openings, unheated galvanized cabinet with obsidian black powder coat, three 1/2 HP motors, 208-230v/60Hz/3-Ph, 1.5 kW input, 5.4/4.8 amps, cETLus certified, 12.75" depth, 175 pounds weight.#@@#General Info#@#Description #@#
Stop losing conditioned indoor air to open doorways. This industrial air curtain delivers a concentrated airstream across a 108-inch opening to reduce infiltration, maintain indoor climate control, and lower HVAC load while operating on 208/230 volts with three 1/2 HP motors for sustained performance.
#@@# Three Motor Design#@#
Three motors produce balanced airflow across wide openings, ensuring consistent air separation for doors up to 108 inches and openings up to 12 ft high. Engineers specified three 1/2 HP motors to deliver stable volume without overtaxing electrical supply at 5.4/4.8 amps.
#@@# High Voltage Operation#@#
This unit runs on 208-230v at 60 hertz and 3-Ph power, matching common commercial electrical systems for straightforward integration. Installers will appreciate the unit’s 1.5 kW input rating and predictable electrical load during planning.
#@@# Unheated Configuration#@#
The unheated configuration removes heating elements to prioritize airflow and energy savings where thermal lift is unnecessary. Facility managers can apply this model in climates or zones where temperature differential does not require supplementary heat.
#@@# Rugged Cabinet Finish#@#
Obsidian black powder coat protects the galvanized steel cabinet against corrosion and daily wear in high traffic zones. Maintenance crews will find the finish easy to clean and resistant to scuffs from routine handling.
#@@# Certified Safety#@#
cETLus certification confirms compliance with applicable North American safety standards and simplifies approval for commercial installations. Procurement teams gain confidence from documented third-party testing.
#@@# Compact Depth Profile#@#
Measured at 12.75 inches in depth with a height near 12.13 inches, the unit fits tight header spaces above industrial and institutional doors. Contractors can mount the unit with minimal intrusion into door header assemblies, preserving clearance.
