The Silent Pac enclosure is engineered for durability, ease of operations and maintenance. This enclosure is designed with full secondary containment. The noise level of the Silent Pac is less than 70 decibels at 23 feet. The enclosure has doors that allow for easy access to operating controls and for regular maintenance. Air vents are strategically located to provide maximum air-flow to the engine.
