TRD 25 flexible insulated silencers deliver exceptional acoustic and thermal performance for ventilation and air conditioning systems. Their micro-perforated design ensures optimal sound attenuation while maintaining energy efficiency.

Manufactured with 25 mm anti-allergic pink glass wool insulation and a metallized polyester outer jacket, these ducts provide a thermal resistance of 0.65 K.m²/W. Their B-s1, d0 fire resistance class ensures maximum safety.

Designed for installations requiring effective noise reduction, these silencers withstand temperatures from -30°C to +140°C and operating pressure up to 1500 Pa, making them ideal for professional HVAC applications.

The SAR circular sound attenuator provides effective noise reduction in ventilation and air conditioning systems. Perfect for both supply and extract air applications.

Manufactured from galvanized steel with a perforated inner surface and 50 mm glass wool insulation. The space between the perforated sheet and insulation is covered with a non-woven antibacterial fabric for optimal acoustic performance.

Easily installed between two circular ducts, ensuring seamless integration into your HVAC network while maintaining efficient airflow.

Rectangular sound attenuators BTH-B2 are designed to effectively reduce noise generated by fans and air conditioning equipment, with maximum sound attenuation in the 250Hz octave band.

Featuring built-in B2 attenuation splitters, these silencers deliver superior performance compared to classical absorption attenuators at frequencies from 63 to 500 Hz. Available in 100mm thickness for smaller airflow rates and 200mm for larger airflow requirements.

Manufactured from galvanized steel sheet compliant with air tightness class C (ATC3), with high-efficiency absorption material and cellulose foil protection, they are incombustible class A1 according to Euroclass DIN EN 13501-1.
