The high-efficiency filter buffer box is the auxiliary equipment of the dust collector, which is widely used in the production workshops of the sanitary products industry, the textile industry, the paper industry and so on to make up the air and regulate the temperature in winter. The heat generated by the dust-containing fan of the production line is filtered by the dust collector, and the clean hot air is switched to the high-efficiency filter buffer box through the regulating air valve according to the flow rate of the fan, and then discharged to the production workshop through the second filter of the high-efficiency filter buffer box, forming a circulating body temperature And the degree of cleanliness fully meets the national and industry standards, and the temperature effect of the tens of thousands of air volume generated per hour can significantly increase the temperature of the workshop. The high-efficiency filter buffer box is made of high-quality materials for heat preservation, fire prevention and noise reduction. The workshop is equipped with a high-efficiency filter buffer box, which greatly improves the ventilation and temperature environment in the workshop, and improves the product quality and significant energy-saving effects. In summer, when the workshop does not need hot air, the air valve can be adjusted to switch to the outdoors and directly discharged into the atmosphere.
