As a renter of inflatable jumping castles, you should not only buy high-quality inflatables, but also pay attention to the quality of the blowers. In order to save costs, some manufacturers will provide poor quality fans. As far as I know, the HUA WEI brand blower is one of the best blower brands in China, and the price is very high. Generally speaking, it has a power of 1100W and 1500W, but since the price difference is not big, it is recommended to choose a high-power blower of 1500W. HUA WEI blowers are CE safety certified and can be used with confidence. There are safety baffles at the entrance of the blower. Once the power is turned off, the baffles will automatically close to prevent foreign objects from entering. The normal lifespan is about 5 years. The size of the HUA WEI fan is 50cmx50cmx50cm, and the weight is only 16kg.
