Box Fans

Non-Insulated Box Fan - BFS Square

image002
BFS is a duct fan with square connections. BFS has high capacity and very good efficiency. BFS is very compact, with only slightly larger dimensions than the duct.
BFS is available with AC or EC motor. Air flows up to 19,080 m³/h (5.3 m³/s).

The IRB, equipped with 50 mm of thermal and acoustic insulation makes it ideal for handling cold air. Designed for high pressure and long, complicated duct runs.
IRB is available with AC or EC motor. Airflows up to 10.800 mᵌ/h (3.00 mᵌ/s).
