Custom Kit. Fantech’s Kitchen Ventilation System contains all the components needed to build a custom range hood: a stainless steel hood liner, a remote inline fan, and an optional inline silencer. The liner comes in 30-, 36-, 42-, and 48-inch sizes and includes filters, lights, and controls; the fans come in 400- to 1,200-cfm models. The silencer reduces fan noise by 50 percent, says the maker. Prices start at $900. Fantech, 800/747-1762. fantech.net
