Stop compromising airflow control for energy waste. This industrial air curtain provides focused high-velocity airstreams across wide openings while operating on a 208-230v, 60 Hz, 3-Ph electrical supply, enabling consistent separation between interior climates and exterior conditions. Mars Air Systems designed this unheated unit with durable coatings and serviceable components to support continuous commercial use.
#@@# High Velocity#@#
Delivering concentrated airflow from three motors, the unit pushes air across openings up to 131 inches and maintains thermal separation for entries up to 8 ft. Wide coverage reduces infiltration and preserves conditioned air in dining rooms, kitchens, and hospital entries.
#@@# Three Motors#@#
Each motored section uses a 1 HP drive, supplying redundancy and even performance across the curtain length. Service technicians can address a single motor without removing the entire assembly, minimizing downtime.
#@@# Robust Construction#@#
Constructed from galvanized steel and finished in titanium silver powder coat, the housing resists corrosion in humid or high-traffic environments. Facility teams receive a resilient exterior that simplifies routine cleaning and sustains appearance over time.
#@@# Electrical Compatibility#@#
Designed for 208-230 volts at 60 hertz with three-phase input, the unit integrates with typical commercial electrical infrastructure. Engineers benefit from predictable power requirements and straightforward connection to three-phase distributions.
#@@# Wide Door Integration#@#
Sized for door openings from 120 inches to 131 inches, the curtain adapts to large storefronts, service entrances, and loading bays. Installers gain a single continuous unit option that eliminates gaps and uneven airflow common with multiple smaller devices.
#@@# Safety and Compliance#@#
ETL sanitation listing confirms adherence to applicable safety and sanitation standards for commercial facilities.
