• Compact and aesthetic structure. The cabinet features a frame and panel assembly design. The frame is formed in one stretch using domestically advanced metal cold-bending machines, while the panels adopt a composite structure with a sound-absorbing material inner layer to further reduce noise.

• Available in various air inlet and outlet directions to meet diverse installation requirements. Featuring mold-based production, it offers high dimensional accuracy and can be reassembled after disassembly.

• The fan's main component, the impeller, is manufactured from high-quality galvanized sheets using mechanized production. This is based on digestion and absorption of products from the US LAU Industrial Company.

• The HTFC series dual-purpose low-noise cabinet centrifugal fans for fire protection and ventilation are available in Type A and Type B. For Type A, the motor is installed outside the cabinet for fire smoke exhaust; for Type B, the motor is installed inside the cabinet for ventilation.

• For the Type A fire-fighting low-noise cabinet centrifugal fan, the motor is installed outside the cabinet, isolated from the high-temperature smoke exhaust system. This ensures continuous operation for over 60 minutes at a high temperature of 300°C. Having passed inspection by the National Fire Fighting Equipment Quality Supervision and Inspection Center, its performance reaches a leading domestic level. It is recognized by fire departments in more than thirty provinces and cities nationwide and has been granted a certificate of approval.

• If a user requires a fan with a large air volume, the company can manufacture a parallel-connected dual-purpose low-noise centrifugal fan for fire protection and ventilation.
