2LG810-7AH27 7.5kW High-Pressure Blower
SPA Whirlpool Application Solution
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.
This model features high airflow, high pressure, low noise, and maintenance-free operation. It continuously supplies air to multiple bubble nozzles, creating a uniform and comfortable massage effect. Typical parameters for this model include: maximum airflow approximately 530 m³/h, maximum pressure 430 mbar, maximum vacuum -320 mbar, and a total weight of approximately 66 kg.
Working Principle
The blower uses a high-speed rotating impeller to accelerate and pressurize the air multiple times within the side channel.
After compression, the air enters the bubble channel at the bottom of the whisker, where it is then evenly released into a large number of microbubbles through the bubble nozzles. A large amount of air enters the water, creating:
bubble massage, water circulation, water turbulence, and oxygen-enriching effect.
The entire process requires no lubricant, therefore it does not pollute the water.
