Isolate Interior from Exterior: UL & CE certified. The air curtain creates a high-speed airflow at the entrance to isolate the inside and outside air environment and avoid 90% of hot or cold air, smoke, and exhaust gas. NOTE: Air curtain is not a wall mount air conditioner. It can not bring cold or hot air.
2 Speeds At Lo/Off/Hi Switch: High speed: 668 CFM (power: 378W); Low speed: 577 CFM (power: 337W). You can switch between two speeds as you wish. Pure copper motors consume less power than other commercial air curtains.
2 Limit Switches Included: Roller plunger micro switch and adjustable roller lever arm limit switch for easy door mounting. The indoor air curtain automatically opens when the door is opened and closes when the door is closed.
Easy Installation: This air curtain is suitable for 118" (3 m) high doors. Referring to the user manual, attach the mounting plate securely, hang the air curtain, install the optional door switch, and connect to the dedicated two wires.
Low Noise & High Applicability: The newly designed air curtain achieves quiet operation (?50dB) and is ideal for installation at the entrance of shopping malls, restaurants, supermarkets, and lobbies.
