The secondary trap from Moro USA is designed to help eliminate excessive pump wear and damage in the event any material escapes past the primary trap. The secondary trap is placed between the vacuum pump and the primary trap, offering an additional layer of protection for the vacuum pump. It fits all Moro air-, fan- and liquid-cooled vacuum pumps up to 600 cfm, and is available in 3- or 4-inch applications. It is made of cast iron and has integrated mounting brackets to make mounting easy and quick while allowing it to be disassembled for inspection and maintenance. 800/383-6304; www.morousa.com.
