QDPYW High-volume Backward Curved Centrifugal Blower

The high-volume centrifugal blower utilizes backward-curved fan blades driven by a high-powered motor to generate high airflow with high pressure and low noise. This equipment is especially suitable for exhausting smoke from kitchens and other applications to high altitudes.

Features The pressure generated by the high-volume backward curved centrifugal blower is one to two times higher than that of traditional fume hoods and various kinds of centrifugal fans while providing the same amount of air flow. Therefore, this design can meet the requirements of commercial kitchen smoke exhaust systems. The smoke exhaust effect of this centrifugal blower is two to three times better than traditional fume hoods and other centrifugal fan designs, proving itself as a superior alternative. It has excellent smoke exhausting effects and can completely discharge the smoke and cooking oil fumes created by teppanyaki and other types of cooking that can create unclean air. The centrifugal blower is equipped with conjoined oil bath bearings and a motor manufactured by trusted brands. It is durable and can provide a long service life up to 15 years. This centrifugal blower is designed with a detachable structure making it convenient to transport, maintain, and clean. Oil stains are normal and do not require additional cleaning. Specifications
