General information and application
At LUVE, we have developed the Whisperer Plus® silencer to provide an advanced solution that significantly reduces both energy consumption and noise emissions. Our design process combines rigorous numerical simulations with extensive experimental testing.
Through these analyses, we have optimized a range of geometrical shapes and material combinations to maximize both aerodynamic performance and acoustic attenuation. The result is a conical, diverging duct design that allows for effective pressure recovery and reduces airflow velocity while maintaining a constant flow rate. In addition, the use of high-performance soundproofing materials delivers superior noise control without compromising fan performance.
The Whisperer Plus® silencer is especially effective when applied to large fan units, where noise and energy consumption are often critical factors. Its advantages are even greater at higher fan speeds, creating a quieter environment and reducing operating costs.
This solution reflects our commitment to sustainable innovation and meets the growing demand for products that balance efficiency with environmental responsibility. The Whisperer Plus® is available in a range of diameters, making it suitable for installation on multiple units. It can be supplied pre-installed or easily fitted as a retrofit onto existing systems, offering flexible integration to meet various operational requirements.
