Product Description:

A soundproofing cover for fans is an effective noise reduction measure for high-noise equipment, enclosing the devices with high noise levels to effectively block the transmission of noise from these high-noise equipment, reducing the impact of noise on the environment. It may sometimes cause inconvenience for equipment maintenance, monitoring, and pipeline layout, and is not conducive to the heat dissipation of the covered devices, with most requiring ventilation facilities to cool the air inside the cover.
Aerodynamic noise cover features: The noise insulation covers produced by Jin Gong Machinery are composed of soundproof components and supporting structures. Depending on different requirements, the cover walls are made of 1.5-2mm galvanized steel plates, aluminum plates, and other metal materials. The noise cover is designed in a modular manner for easy transportation, on-site installation, and convenient maintenance. Transparent doors/windows, lighting equipment, and ventilation heat exchange systems can be installed according to different usage requirements. Custom sizes and various exterior colors can be painted as per request.
Application of Fan Noise Dampening Enclosure: Suitable for reducing noise from various equipment such as blowers, exhaust fans, generators, air compressors, transformers, crushers, ball mills, motors, pumps, woodworking machinery, printing machines, etc. It can be used in the control room of a high-noise workshop to minimize the harm of noise to humans. Equipped with ventilation and cooling, heat dissipation devices, as well as intake and exhaust mufflers, it ensures the normal operation of the equipment. Our company can independently complete the design, manufacturing, and installation of soundproof enclosures; we have successful project cases including stamping machine enclosures, Roots blowers, and centrifugal fan enclosures.
Acoustic Duct Effectiveness: Generally, an acoustic duct cover can achieve 10-30 dB of sound insulation based on the design of the cover.

Wind Turbine Noise Control Measures: In addition to considering the noise at the air outlet, the noise and vibration transmission of the wind turbine body should also be given attention based on the on-site conditions. Since wind turbines generate a significant amount of noise during operation, and the noise level of the wind turbine increases with the increase of air volume and wind pressure. Common methods to address wind turbine noise issues include:
(1) Noise from the housing and motor can be mitigated by installing soundproof enclosures. Place the fan in an independent soundproof room, and apply sound-absorbing and soundproofing treatments within the room.
(2) Install a silencer outside the fan exhaust outlet, featuring built-in noise-reduction inserts to continuously reduce noise through its special construction. Silencers are an effective measure for reducing the noise radiation or transmission along the pipeline of air-moving equipment's intake and exhaust ports.
(3) Opt for sound-absorbing louvers for the exterior window of the ground floor as much as possible.
(4) Vibration dampers with damping spring hangers are used for fan suspension.
(5) Overall vibration isolation treatment for the fan foundation.
