The F-Series is Ice Qube's filter fan bank cooling system designed to cool your equipment by forcing and draining the internal heat load from your application. Ice Qube engineers have created the F-Series product lines of FP, FPP and FP-H after extensive testing and final development. FP is Ice Qube's steel filter fan pack, FPP is our plastic filter fan pack, and FP-H is our internal flush hood filter fan pack. Ambient air inlets and exhaust flush hoods protect against direct water, splashing liquids and harsh outdoor applications.
