Product Name: Multi-Function Surge Oxygen Aerator (YYL-0.75) Model NO.: YYL-O. 75 Finished processing machinery: Shellfish and seaweed Processing Machinery Condition: New Certification: CE, ISO9001:2008 Fishing Auxiliary Machinery Type: Fishing Tackle Auxiliary Machinery Aquatic Products Processing Machinery: Finished processing machinery Power Source: Electric Working Method: Friction Type Type: Farming Machinery Transport Package: Export Standard Carton Specification: CE Origin: Zhejiang China HS Code: 8414809090 Product Description surge aeratorsurge capcacity: in spite of 40mm diameter itself, the multifunctional surge type aerator has the strong capacity of making wave and can spread the aerated water in an area up to 60mm diameter, this product could greatly increase the contact area between water and air. thereby it could increase oxygen content in water, improve water quality and reduce sewage dischage by means of aeration, air contact, algae photosynthesis and ultraviolet radationpumping capacity: the multifunctional surge type aerator has strong capacity to pump water from deep to suface.it could effectively reduce the content f toxic substances and ases in water, such as ammonia nitrogen, nitrite, hydrogen sulfide and E. coli. Thus, it could improve the quality of pond sediments and prevent water pollution.Aeration capacity: this type aerator is the replacement of paddle wheel aerator and therefre more efficient than in predecessor.* the design isartistic and reasonable, the material of components used are environmentally friendly, robust and durable with paint on surface.* most of the accessories are standard, wgicg are easy ti maintain.* adcance technology is applied in the design and manufacture of the motor and gear deceleration system to reduce noise and improve efficiency and insulation level. Therefore, multifunctional surge aerator is safe, economic, energy-saving and environment friendly
