Negative pressure fan motor product features: 1. Negative pressure fans for the following various operating conditions: High-temperature or odor-causing workshops: such as heat treatment plants, casting factories, plastics factories, aluminum profile plants, shoe factories, leather goods factories, electroplating factories, printing and dyeing factories, and various chemical plants. Applicable to labor-intensive enterprises: such as garment factories, various assembly workshops, Internet cafes. The horticultural greenhouses are ventilated and cooled, and the livestock farms are cooled. It is especially suitable for places that need to cool down and require a certain humidity. Such as cotton spinning mills, wool spinning mills, hemp spinning mills, weaving mills, chemical fiber mills, warp knitting factories, bombing factories, knitting factories, silk weaving factories, socks factories and other textile factories. 2. The motor adopts Class F insulation, high heat resistance temperature, strong impact resistance and long service life of insulation. 3. The motor casing is made of die-cast aluminum alloy, which has stable structure, various shapes, good heat dissipation, convenient installation and use, stable performance, safety and reliability.
