China Factory Suppliers Ventilating Exhaust Rotor Blower Cabinet - Operating from -20 to +40℃ with High Temp Resistance
Product Overview
1. The DBF type cabinet-type centrifugal fan is a high-efficiency, low-noise unit. It consists of a low-noise forward-tilted multi-blade centrifugal fan, motor, bearings, transmission components, and a sound-absorbing cabinet. Depending on the installation location, 12 different angle inlet air positions can be provided.
2. To meet the requirements of explosion-proof environments, the fan can be made into an explosion-proof fan (Grade: EXdⅡBT4), suitable for places with flammable and explosive gases.
3. To meet specific noise requirements, the fan can be equipped with different lengths of mufflers or thickened muffler-type cabinets to significantly reduce operational noise.
4. The fan can be equipped with primary, secondary or high-efficiency filters to improve air cleanliness. Actual pressure loss and cabinet length adjustments are considered during configuration.
Product Application
Fans can be widely applied in various places such as hotels, restaurants, auditoriums, cinemas, basements, long-term mining enterprises, and office buildings. They are particularly suitable for environments that require low noise and large air volume.
