Description

The LSP soundproof grille is a high-performance, space-saving silencer designed for installation in air intake or exhaust ducts in HVAC and industrial systems. Made with innovative Slim Hurdle™ technology , it features ultra-thin 20 mm sound-absorbing baffles with variable orientation (horizontal or vertical), ensuring high acoustic efficiency with low pressure drops, often less than 5 Pa.

The optimised design allows for net free surfaces of up to 75%, with double the efficiency of similar products on average, making LSP grilles ideal for applications on heat exchange batteries, radiators, chillers, air conditioners and heat pumps.

Thanks to their compatibility with Quiet Leaf™ panels , they can be perfectly integrated into soundproof booths, acoustic barriers and sound-absorbing shells, even in very small spaces.
