SE Sound Splitters
SE sound splitters are available as combined absorption and resonance splitters or pure absorption splitters. With eight attenuator thicknesses and flexible size options for length and height in 1-mm increments, they offer a wide range of customisation options. Flow-optimised attenuator covers minimise pressure loss and flow noise and increase energy efficiency, while the design ensures high static load capacity.
Technical details
- Low pressure loss due to optimised splitter cover profile for low energy consumption
- Different splitter types as absorbers or broadband for optimal fulfilment of requirements
- Small sizes possible for good sound attenuation in confined spaces
- Different splitter thicknesses for maximum flexibility
- Improved insertion loss
- High-quality workmanship with smooth edges for safe handling
- Straight edges between splitters and duct wall to avoid dirt traps and meet high hygienic requirements
- LABS & silicone-free
- Hygiene certificate in preparation
- Lengths in 1 mm increments

Product details
Sound attenuators/splitters SE are special components for use in splitter attenuators or in air ducts to reduce flow noise in ventilation and air conditioning systems. They are designed to effectively attenuate the sound generated by the flowing medium air. SE sound attenuators/splitters are either designed as combined absorption and resonance sound splitters (broad bands, SE-B) or as pure absorption sound splitters (absorbers, SE-A).
A wide range of splitter thicknesses, as well as the option of manufacturing in millimetre increments in height and length, guarantee an optimal adaptation to the requirements for the required duct size.
Structure of sound attenuators/splitters SE
The splitters are designed with two chambers and are suitable for use in ventilation and air conditioning systems. The outstanding features of their design are their high static load capacity and the aerodynamically shaped splitter covers.
Together, these features result in a durable and energy-efficient product. Their degree of stability is achieved by two frame legs mounted back to back, whereby these are firmly connected to each other by a crimp connection, which gives the linkage a particular stability. The frame legs, in conjunction with aerodynamically shaped linkage lids, form two chambers per linkage and hold the absorption material.
The surfaces of the absorption material used are made of rot-proof, biosoluble mineral wool. These are covered with tear-resistant, abrasion-resistant and moisture-repellent glass silk (glass filament fabric) in the case of an absorption baffle. In the case of a broadband baffle, a galvanized sheet steel alternately replaces the glass silk. The absorption materials are hydrophobic, which makes it difficult for moisture to penetrate them.
Sound attenuation
The broadband sound attenuation of the absorption and resonance sound attenuator baffle is optimised in the critical frequency range of 250 Hz. They reduce a wide range of noises across a broad spectrum of frequencies, with a particular focus on the low and medium frequency range.
The sound attenuation of the pure absorption splitter is optimised in the frequency range of about 1,000 Hz and is characterised by very high attenuation of disturbing noises, with a particular focus on the medium and high frequency range. These sound attenuation levels are guaranteed for each of the shortest possible lengths, so that the SE sound attenuators/splitters can be designed to be as compact as possible.
SE splitters are available in an extensive range of sizes and thicknesses, they are stackable and have a certificate of compliance to prove non-combustibility (ÜZ DIN 4102 A2).
