The unit is ETL, ASME, and CRN certified.\u003c\/p\u003e\n\u003cp\u003eThis is a Silent Air model. EMAX's patented noise suppression system runs \u003cstrong\u003eup to 50% quieter\u003c\/strong\u003e, with noise levels at or below conversational volume — each 10 dBA drop reads as half as loud to the human ear. Unlike enclosed cabinet systems, which cost more and restrict service access, the silencer design keeps the pump fully accessible for maintenance. The intake system attacks the loudest source of compressor sound with noise-reducing baffle plates, high-capacity filter media, and up to 1000% more filtration than standard setups.\u003c\/p\u003e\n\u003cstyle\u003e.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }\u003c\/style\u003e\n\u003cdiv class=\"embed-container\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/atakh7WsbDY\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cp\u003eThe compressor is built for sustained workloads: a \u003cstrong\u003e60% duty cycle\u003c\/strong\u003e with \u003cstrong\u003econtinuous-run capability\u003c\/strong\u003e.
