L-OL-4 ACOUSTIC LOUVER

The L-OL-4 is an acoustical louver engineered for air intake and exhaust applications where noise attenuation is required. It features internal acoustic insulation using ATAC — a semi-rigid board composed of biosoluble glass mineral wool bonded with a thermosetting resin. This material provides acoustic absorption and long-term dimensional stability.
