Silenciador de codo rectangular
A 90-degree rectangular sound attenuator with radiused acoustic baffles that combines airflow turning and noise reduction where straight duct length is limited.
- 90-Degree Space-Saving Form
- Radiused Acoustic Baffles
- Combined Turning and Attenuation
- Multiple Airstream Liner Options
Introducción del producto
The rectangular elbow silencer integrates curved acoustic baffles into a 90-degree duct bend. The change in direction blocks direct line-of-sight noise propagation and provides strong mid-frequency attenuation within a compact footprint. Internally radiused splitters guide airflow through consistent passages to limit separation and pressure loss. Absorptive, film-lined or packless baffle construction is selected according to the cleanliness and acoustic requirements of the air system.
Características clave
Radiused splitter passages turn the airflow while avoiding abrupt square-corner recirculation zones.
Eliminating direct line of sight improves attenuation through the mid and higher frequency range.
Film-lined and packless versions support hygiene-sensitive or fiber-restricted air streams.
Preocupaciones del producto del cliente
A compact acoustic elbow must maintain uniform passage velocity through the bend; poorly shaped baffles can trade noise reduction for excessive pressure and generated noise.
There is no straight run available for a conventional sound attenuator.The elbow unit performs the required 90-degree turn and acoustic treatment in one component.
A square elbow separates airflow and creates its own low-frequency rumble.Radiused baffles maintain smoother velocity distribution around the bend.
Direct fan noise passes through an ordinary turning-vane elbow.Acoustic baffles interrupt line of sight and absorb sound along each curved passage.
Exposed fibers are unsuitable downstream of final filtration.Film-protected or packless internal construction keeps the airstream free of exposed absorptive fill.
