Mars is introducing the LoPro, a quiet, architecturally designed low-profile air curtain only 8 inches tall. The LoPro protects against flying insects (ETL sanitation certified) while significantly reducing building heating and cooling costs, says the company. LoPro is available in a sleek Obsidian Black metal housing in lengths from 30–144 inches to match door widths. This lightweight design weighs only 34 lbs. for the standard 36-inch model and is easy to install and maintain.
