Simply remove segments to open the airway; the more segments you remove, the higher the airflow, while retaining significant sound insulation. - VARIABLE SOUND ATTENUATION: Achieve the perfect balance for your setup. With segments in place, this professional silencer provides staggered noise reduction levels: 44 dB, 39 dB, 35 dB, and 30 dB(A) as you adjust the internal configuration. - PRECISION TUNING: At least one segment must be removed to allow airflow. This manual adjustability gives you full control over the static pressure and decibel output of your 4-inch (125mm) duct system, a feature standard "fixed" mufflers lack. - HEAVY-DUTY GALVANIZED STEEL: The rugged housing is built from corrosion-resistant galvanized steel, ensuring the internal acoustic elements are protected in high-humidity environments like grow tents or industrial HVAC systems. - HIGH-PERFORMANCE ACOUSTIC FOAM: Each removable segment is lined with premium, perforated sound-absorbing material.
