Ürün tanıtımı

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.

Ana Özellikler

The 90-degree geometry fits acoustic treatment into plant rooms that lack a long straight duct section.

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.

Müşteri Ürün Sorunları

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.
