The compound eyewash device can open the eyewash part and the shower part separately, or open the eyewash and shower at the same time. The eyewash part and the shower are on the same side. The Bohua eyewash assembly is a one-time casting molding with smooth surface, strong pressure resistance and long service life. There is no burst phenomenon in winter or high water pressure. Inferior quality always becomes welded parts. The workmanship is relatively rough and mostly welded, which not only affects the appearance but also shortens the service life. In cold areas or when the water pressure is high, it is easy to cause the expansion of the tube to burst.
