• Draft chamber

The "ELB type" is an elbow silencer (muffler) that can be selected according to duct dimensions and required attenuation. Compared to conventional silencing elbows, it provides greater attenuation and has less airflow deflection in the curved section, allowing effective noise reduction with just one silencer immediately after the machine room. If the inlet and outlet dimensions are different, please consult us for design. 【Features】 ■ Silencers can be selected according to duct dimensions and required attenuation ■ Suitable silencers can be chosen from many special specifications ■ Greater attenuation than conventional silencing elbows ■ Low pressure loss and generated noise ■ Standard module dimensions available in increments of 50mm from 250 to 600mm *For more details, please refer to the PDF materials or feel free to contact us.

The "Shizuka S Type" is a soundproofing device for the discharge of outdoor units that is compatible with various manufacturers' products. It features a baked paint finish in the same color as the outdoor unit. Weighing approximately 38 kg, it can be installed directly on top of the equipment. There is also a lineup of the "Shizuka SII Type," which has a low pressure loss of about 5 Pa or less. Additionally, this product only targets discharge side noise. If measures against intake side noise are necessary, using it in combination with the "Shizuka F Type (soundproof hood)" or "Shizuka L Type (soundproof louver)" is more effective. 【Features】 - Weight that can be installed directly on top of the equipment (S Type approximately 38 kg) - Baked paint finish in the same color as the outdoor unit - Low pressure loss (S Type approximately 16 Pa, SII Type approximately 5 Pa or less) - Soundproofing performance can be produced at standard type approximately 10 dB, high-performance type approximately 15 dB and 20 dB - Compatible with various manufacturers' products both domestically and internationally *For more details, please refer to the PDF materials or feel free to contact us.
