Our company's independently developed EF series high-efficiency air purification dedicated fan case integrates more than ten years of technological accumulation and precipitation, and has multiple technological advantages. The overall performance of the fan is industry-leading.
1. Efficient air purification cabinet centrifugal fan
The box structure not only strengthens the strength of the unit itself, but also solves the problems of air leakage, strength, and consistency; It has the characteristics of compact structure, beautiful appearance, easy installation and maintenance, strong rigidity of the whole machine, and low air leakage rate. The application of interlocking technology inside the box makes assembly simple and convenient; The special concave convex groove design makes it easy to achieve scientific combination between the wall panels: the use of reinforcement technology inside the panels makes the surface of the unit continuous and smooth, with a clear and smooth appearance and higher mechanical strength.
2. Technical characteristics of high-efficiency air purification dedicated fan
① Adopting the self-developed sixth generation (Owlwing) impeller, it achieves drag reduction and noise reduction technology, which is in line with the optimal tooth profile combination for this type of fan. The number of teeth, tooth height, tooth width, and the gradual combination of teeth are key factors affecting the efficiency and noise of the fan. The acoustic comparison test results reveal that biomimetic serrations are beneficial in preventing the formation of shedding vortices on the blade surface due to turbulent boundary layer, and have a certain effect on noise reduction and sound quality improvement of the fan. Effectively reduces high-frequency eddy current noise, achieves high-precision balance of the impeller, and can meet the international standard G2.5. The overall vibration value of the machine can be controlled between G1.0-G2.0.
② Maintenance door: The fan is equipped with a large-sized maintenance door that can be freely removed as a whole. The maintenance door must be fastened on the inside of the box, and the insulation material must be used to seal between the maintenance door and the box frame. The maintenance door must be equipped with a high-strength fire-resistant handle, and the fixing method of the maintenance door is lock locking (cannot be fixed with bolts or self tapping screws). The lock locking foot must be matched on the aluminum alloy profile frame and locked with bolts. Each maintenance door must be equipped with more than 4 sets of locks, and the outer packaging material of the lock on the maintenance door must be fire-resistant engineering plastic.
③ Wind outlet flange: Both the inlet and outlet are equipped with connecting flanges, which are made of aluminum alloy or galvanized sheet material to facilitate soft connection with the air duct and ensure a long service life in humid environments.
④ Dense pleated sub high efficiency filter, filter material is glass fiber filter paper or ultrafine polypropylene filter paper, filter efficiency can be selected from H9~H13, filter area is large, resistance is small, initial resistance is less than 400Pa; The outer frame is made of high-strength environmentally friendly plastic and sealed with a new type of polyurethane sealant; The overall environmental protection is incineratable, non-toxic and odorless, easy to dispose of, and meets the environmental requirements of clean operating room construction standards.
