The Cristal HC is fro the serious cook who need more ventilating power, but wants an understated rangehood. The 500 cfm blower is housed inside the cabinet, leaving only the slim slide-out visible. When the unit is closed, the front trim is flush with the cabinet. Sliding open the front of the rangehood reveals a hidden three-speed control panel and activates a microswitch which turns on the blower and the light. When the hood is closed, the blower and light automatically shut off. For a totally integrated look, replace the front strip with the material to match the cabinets. For recirculating installations, a charcoal filter kit is required. For vented installations, 6" round ducting required (can be transitioned to 3 1/4" x 10"). Features Top or Direct Rear Venting.
