The 2LG810-7AH27 is a 7.5kW single-impeller high-pressure ring blower (Side Channel Blower). Utilizing a high-pressure regenerative impeller design, it continuously provides stable, clean, oil-free compressed air, widely used in large SPA whiskers, hydrotherapy pools, hot spring pools, water parks, and commercial swimming pool bubble massage systems.

Blowers (also commonly referred to as aeration blowers​ or blower fans​ in the industry) are among the most energy-intensive and critical pieces of dynamic equipment​ in wastewater treatment plants (WWTPs). The power consumption of aeration system blowers in a typical WWTP can account for 50%~70%​ of the plant's total electricity usage. Therefore, they are not merely "air-blowing devices" but rather the "power heart"​ of the entire facility.

With 25 years of professional blower manufacturing and 17 years of export experience, we supply high-performance regenerative blowers tailor-made for air knife systems. All products come with a 2-year warranty to guarantee stable 24/7 operation on industrial production lines.

With the rapid development of large-scale agricultural planting, saving water and increasing efficiency has become the core demand of irrigation industry. With the advantages of stable wind pressure and moderate energy consumption, high-pressure blowers are widely used in various irrigation systems in modern agriculture, breaking the shortcomings of traditional irrigation water waste and extensive control.

High-pressure blowers are essential core equipment for modern wastewater treatment systems, widely used in municipal sewage treatment and industrial wastewater purification. Serving as the key air supply source for aerobic biochemical treatment, they directly affect system stability, treatment efficiency and effluent quality, helping water treatment facilities optimize processes and reduce long-term operating costs.

High pressure blower is the core equipment for oxygenation and aeration in swimming pools. With the advantages of efficient pressure boosting and stable air supply, it is widely used in public swimming pools, private swimming pools, and pool water treatment systems. It can ensure clean water quality and enhance swimming experience, adapting to the oxygenation needs of various swimming pools.

Submersible pumps play an indispensable role in various fields, including agricultural irrigation, industrial water supply, residential drainage, and wastewater treatment. As the core component of submersible pumps, the motor’s material directly determines the pump’s performance, efficiency, service life, and overall operational cost. Among the common motor winding materials, copper and aluminum are the two most widely used options. While both can drive submersible pumps to complete liquid transportation tasks, their inherent physical, electrical, and mechanical properties lead to significant differences in practical application. This article comprehensively compares copper motors and aluminum motors for submersible pumps from multiple dimensions, helping users make rational choices based on their actual needs.

The core lifeline of aquaculture lies in the dissolved oxygen in water, and the lack of dissolved oxygen will directly lead to fish and shrimp floating head, slow growth, frequent diseases, deterioration of water quality and sharp drop in output. With the core advantages of large air volume, high wind pressure, low noise, constant pressure air supply and 24-hour continuous and stable operation, high-pressure blower (annular high-pressure blower) has now become the standard oxygen supply equipment for industrial aquaculture, high-density fish ponds, shrimp and crab breeding, deep-water aquaculture and other scenes, providing core power support for aquaculture to reduce costs and increase efficiency and green and sustainable development.

Sewage treatment is the key link to protect the ecological environment and ensure the recycling of water resources, and aeration, as the core step of sewage treatment process, directly determines the efficiency and quality of sewage purification. With the advantages of stable wind pressure, controllable energy consumption and reliable operation, high-pressure blower replaces traditional aeration equipment and is widely used in municipal sewage treatment, industrial sewage treatment, rural sewage treatment and other scenes, providing sufficient oxygen for microbial degradation of pollutants, becoming an indispensable "oxygen supply heart" in sewage treatment system, and promoting sewage treatment to upgrade to high efficiency, energy saving and environmental protection. The core function of high-pressure blower (also known as high-pressure blower and vortex air pump) in sewage treatment is aeration and oxygen supply. Its working principle is essentially different from that of fish pond aeration, and it pays more attention to adapting to the complex working conditions of sewage treatment to achieve the dual effects of efficient oxygen transfer and water disturbance.

In aquaculture, dissolved oxygen is the "lifeline" of aquatic organisms such as fish, shrimp and crabs, and it is also the core factor that determines the culture density, survival rate and culture benefit. With the transformation of aquaculture to intensive and high density, the traditional oxygen-increasing equipment has been difficult to meet the needs of oxygen-increasing and uniform oxygen supply in deep water bodies.
