Cleanroom air curtain AAC-20257 series

wall-mountedhorizontal

Product application
Pest-control air curtains create an air barrier with high-speed airflow to prevent insect ingress and reduce foreign object contamination in manufacturing processes such as food and pharmaceutical industries. Units can be designed and manufactured to match existing openings. A version with an integrated sheet shutter is available.

Product highlights

• Prevents insect entry at openings using an unbalanced airflow from both sides (patented).
• Custom-designed to fit opening dimensions.
• High-speed sheet-shutter type provides increased pest-control effectiveness; airflow and sheet shutter operate in sync.
