Jiangyin Machinery Equipment Co., Ltd. is the United States, according to market demand, developed a four suspension chain aeration tube, air leaks can be very good solution, and are not easily damaged, the following small series offers several advantages of the device.

Four suspension chain aeration tube in the double-barreled basically developed new suspension chain aerator. Has a high rate of oxygen use, post-protect brief, effort, low energy consumption and other advantages. It's oxygenation and dynamic power than the power to make progress in general microporous aeration equipment, and can not affect the normal operation (continuous water supply is not suspended), the repair, replace damaged aerator, practical .

A float tube welding comprehensive selection of UV resistant material, completely solve the leakage phenomenon, and long service life.

2 Anti-bump to strong, difficult to damage.

3 built-in check valve, completely solve the defection phenomenon.

4 full selection of corrosion-resistant materials.

5 hanging chain moving aeration tube use of special diaphragm, the diaphragm life long, can reach 5-8 years, completely solve the rubber diaphragm is easy to tear, short life shortcomings.
