Monsoon Dcbl Is Unique In The Marketplace. We Started With A 715-Cfm Dc Motor And Added Stainless Steel Baffle Filters With A Removable Grease Tray For Easy Cleaning. Then We Introduced Vertical And Horizontal Ducting Along With A Wireless Remote Control, And Finally, We Added The Proprietary Dcbl Suppression System?? That Makes Monsoon Dcbl The Most Quiet And Energy Efficient One-Piece Liner Available Today.
