Blower is powered by a 7.5 hp(5.5kw), 1440 rpm motor. Blower was tested before installation. It delivered 4000 m3/hr(66.7 m3/min) to 7000 m3/hr(116.7 m3/min) of air in its optimum working range of 200 mm to 225 mm water pressure gauge. There are eight pipes arranged in two tiers. The first tier has four pipes placed at 3 m depth, the second also has four pipes and is placed 1 m above the first. Each pipe is 23 m long and 20 cm in nominal diameter. Thickness of pipe wall is 3 mm. Pipes are made of mild steel(보통강관), and placed 1.5 m apart. (첨부파일 5페이지에서 발췌)
