The exterior housing of the 5-hp Salvajor 500 food waste disposer is molded from a heat-treated, corrosion-resistant aluminum alloy. The motor is totally enclosed and is fan- and water-cooled for efficiency and longer life. A rubber adaptor above the grind chamber and rubber drain outlet isolates sound and eliminates vibration. Like all Salvajor disposers, it offers dual-direction grinding. Purchasers may add operator sensor technology to this machine as an option.
