neverest® ESD 3" Adjustable Inline Duct Silencer – Modular Sound Absorbing

neverest® ESD 3" Adjustable Inline Duct Silencer – Modular Sound Absorbing

• MODULAR AIRFLOW & NOISE CONTROL: Features a unique 5-segment design that allows you to customize your ventilation. 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 33-inch (80mm) 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. It effectively traps air turbulence and mechanical fan noise before it exits your ventilation pipe.
