XQZ type fire-fighting pneumatic automatic water supply equipment is a new type of fire-fighting water supply equipment, which is developed on the basis of "Fire Protection Code for Construction Design", "Fire Protection Code for Design of High-rise Civil buildings" and "GA30-92" issued by the Ministry of Public Security, which comprehensively absorbs the characteristics of modern pneumatic water supply equipment and fire water working conditions, and is developed on the basis of reforming traditional air pressure water supply equipment. The equipment can supply water directly under pressure, which not only improves the water supply condition, reduces the power of the pump group, but also significantly reduces the construction cost of the whole machine. This series of products can be widely used in fire protection projects of urban and rural residential areas, mining enterprises and institutions, tall buildings, hotels, military facilities and high-rise buildings.
