Mars Air Doors
Creates an air barrier across a 60 in doorway with 1500 cfm flow and 53 dBA at 10 ft
This low-profile air curtain fits doorways up to five feet wide and mounts at heights up to eight feet. It delivers 1,500 cfm of unheated airflow at 1,800 fpm to create an effective environmental barrier. The galvanised steel housing is finished in silver and measures sixty inches wide by eight inches high. A single permanent split capacitor motor rated at one-sixth horsepower drives the unit on 115 V single-phase power.
At a distance of ten feet the unit produces 53 dBA, a level suitable for retail entrances, offices and similar indoor spaces. The totally enclosed air-over motor enclosure helps contain mechanical noise while protecting internal components. Maximum current draw is 2.6 amps, keeping circuit loading modest for standard 115 V supplies. The closed-base design simplifies installation without sacrificing airflow performance.
The curtain ships ready for hard-wired connection to a 115 V, 60 Hz single-phase circuit; no plug or cord set is included. Mounting hardware is not supplied, so installers must provide appropriate fasteners for the structure. The steel housing and galvanised finish resist corrosion in typical commercial environments. No control panel, remote or thermostat is bundled, allowing integration with existing building management systems.

The unit mounts overhead at up to 8 ft height with a closed base; the step often missed is verifying the 115 V, 1-phase supply and 2.6 A circuit before wiring the permanent-split-capacitor motor.
The totally enclosed air-over motor requires periodic cleaning of the intake and housing to maintain the 1500 cfm flow; bearings are sealed, so lubrication is not required.
At 10 feet the unit measures 53 dBA; in noise-sensitive spaces this acoustic level typically becomes the practical limit before the 1800 fpm velocity or 2.6 A draw reach their thresholds.
