Inquiry (采购产品): Penn State Univ Swift Building generator Specs for this project call for a Harco Slim Type hockey puck style critical muffler for the generator. Minimum sound attenuation 25dB @ 500Hz, sound level measured at a distance of 10 ft from exhaust discharge shall be 85dBA or less. I am quoting a Generac SG070 natural gas generator.
