When you require greater width and depth and larger blower capacity for professional-style cooking equipment, the THPSLE model is available. They provide great ventilation for professional ranges and barbecues. These liners are made to be mounted inside a decorative hood that you create out of wood, plaster, metal or tile. The THPSLE island hood liner gives you all the power of a Vent-A-Hood island hood. The only place where the liner and the outside cover must meet is at the bottom edge of the metal liner in both width and depth. These hood liners feature Vent-A-Hood's Magic Lung filter-less design, which allows you to get more out of the 1200 CFM blower, extending its power to around 1800 CFM. The Magic Lung blower performs better because it uses centrifugal filtration instead of mesh or baffle filtration. Operation is the quietest in the industry, so turning on your hood won't put an end to conversation. The dual level halogen lighting illuminates the cooktop. The SensaSource automatically adjusts the blower speed as heat increases. There are many other reasons to buy a hood liner: they are pre-wired, pre-assembled, and far less expensive than custom made liners.
