Energy-efficient fan

Mingbo high-efficiency energy-saving fan is a new generation of centrifugal/axial flow fan that adopts optimized pneumatic blade type, precision flow channel design, and high-efficiency impeller. Compared with traditional old models such as 4-72 and 9-19, the fan efficiency is greatly improved, motor energy consumption is reduced, and it is suitable for industrial systems that operate continuously for a long time. It is the mainstream product for energy-saving transformation in environmental protection, kiln, dust removal, and HVAC projects.

Model classification

Efficient centrifugal fan (most commonly used in industrial projects) with wing shaped rear curved impeller, optimized aerodynamic model, and low internal losses of the fan. Replace traditional 4-72 Y4-73， Used for dust removal, desulfurization, kiln induced draft, and material transportation.

Efficient axial flow fan with adjustable wing blades, high flow rate and low pressure, suitable for factory ventilation, cooling towers, and air coolers.

Double suction high-efficiency centrifugal fan for high flow conditions, induced draft fan for sintering and large boilers, and main exhaust fan for large production lines.

Energy saving logic: The combination of improving the internal efficiency of the fan and matching the operating conditions with the frequency conversion system yields the best energy-saving effect; Relying solely on frequency conversion results in low efficiency of the fan body and limited energy-saving space.

Whole machine structure

Steel plate welding optimization snail shell+efficient wing shaped rear curved impeller+air inlet collector+bearing box+common base

Impeller: wing shaped hollow blades with low aerodynamic drag; Wear resistant conditions can be welded with tungsten carbide, while corrosive conditions can be treated with stainless steel material

Current collector: streamlined air inlet to reduce intake vortex loss

Shell: Smooth flow channel, reducing backflow and eddy current losses. Accessories: soft connection, spring shock absorber, imported air damper, variable frequency control cabinet, online monitoring (vibration/temperature)

Core Features

The efficiency of the fan body is high: the overall efficiency of the high-efficiency centrifugal fan can reach 82%~89%, while that of the old-fashioned ordinary fan is mostly around 70%. The electricity cost for long-term operation has significantly decreased

Wide operating range, maintaining high efficiency even under variable load conditions, suitable for load fluctuations in kilns and dust removal systems

Lower aerodynamic noise and minimal airflow disturbance

It can balance wear resistance, high temperature resistance, and corrosion resistance, and is suitable for various working conditions such as dust removal, desulfurization, and high-temperature kilns

Supporting variable frequency speed regulation, matching air volume and pressure as needed, further reducing energy consumption; Meet energy-saving acceptance, carbon accounting, and energy efficiency evaluation requirements

Applicable scenarios

Bag dust removal, desulfurization and denitrification, kiln induced draft, drying production line, steel plant dust removal, factory ventilation, sewage treatment aeration, and energy-saving renovation project for old fans.
