2LG810-7AH27 High-Pressure Blower Vegetable Washing Application Solution
2LG810-7AH27 High-Pressure Blower Vegetable Washing Application Solution
The 2LG810-7AH27 is a 7.5kW single-impeller high-pressure ring blower (Side Channel Blower). Adopting a high-pressure regenerative impeller design, it delivers continuous, stable, clean and oil-free compressed air. It is perfectly matched for industrial vegetable cleaning systems, widely applied in commercial vegetable bubble washing machines, central kitchen cleaning lines, fresh vegetable processing plants, fruit and vegetable pre-treatment equipment, and agricultural product cleaning and purification systems.
This blower model integrates high airflow, strong pressure, low noise and maintenance-free performance. It can stably supply air for multi-nozzle bubble cleaning systems, generate uniform and dense micro-bubbles in water, and achieve efficient and damage-free cleaning of various vegetables. The core parameters of the model support large-scale and long-duration vegetable cleaning operations, with a maximum airflow of 530 m³/h, maximum pressure of 430 mbar, maximum vacuum of -320 mbar, and a total weight of approximately 66 kg.
Working Principle
The high-pressure blower relies on a high-speed rotating impeller to accelerate and pressurize air multiple times through the side channel, outputting continuous high-pressure and high-flow clean air.
The compressed air is delivered to the bottom bubble aeration pipeline of the vegetable cleaning tank, and evenly released into the cleaning water through multi-group air distribution nozzles to form a large number of fine and dense micro-bubbles. During the rising and continuous tumbling process, the bubbles produce micro-turbulence and gentle impact force, which effectively peels off surface soil, dust, residual pesticides, insect eggs and fine impurities on vegetables. Meanwhile, the bubble-driven water circulation realizes overall turnover of vegetable materials, avoiding material stacking and cleaning dead angles.
The whole air supply process adopts oil-free compression design with no lubricant participation, ensuring zero oil pollution and secondary pollution to vegetable cleaning water, which fully meets food-grade cleaning hygiene standards. In addition, the continuous aeration effect improves water oxygen content, inhibits bacterial growth in cleaning water, and further guarantees the cleanliness and safety of vegetable cleaning.

Product Core Features
① High Airflow & Uniform Aeration
With a maximum airflow of 530 m³/h, it can support simultaneous air supply for multiple groups of bubble nozzles in large cleaning tanks. It forms uniform and covering bubble tumbling in the water, solves the problem of uneven cleaning of traditional equipment, and realizes all-round cleaning of bulk vegetables.
② High Pressure & Strong Dirt Removal Capacity
The 430 mbar maximum high pressure effectively overcomes water resistance and pipeline transmission resistance. It can generate strong micro-bubble impact force in deep water areas, thoroughly peel off stubborn sediment, pesticide residues and fine impurities on vegetable surface and gaps, with superior cleaning ability.
③ 100% Oil-Free Clean Air, Food-Grade Hygiene
Adopting oil-free compression technology, no lubricant is involved in the air supply process. The output air is clean and pollution-free, which avoids secondary oil pollution to vegetables and cleaning water, fully complies with food processing hygiene standards, and is safe and reliable for long-term use in vegetable cleaning industries.
④ 24-Hour Industrial Continuous Operation
Equipped with industrial-grade high-precision bearings and efficient heat dissipation structure, the blower supports S1 full-load continuous operation. It adapts to the all-weather continuous production demand of large vegetable processing factories and central kitchens, without shutdown and heat failure, ensuring stable and efficient production line operation.
⑤ Low Noise & Environmentally Friendly Operation
The dynamically balanced impeller ensures stable operation with low vibration, and the operating noise is only about 70 dB(A). It can be equipped with a matched silencer to further reduce noise, improving the workshop working environment and meeting industrial environmental protection noise standards.
⑥ Flexible & Space-Saving Installation
The compact aluminum alloy die-casting structure occupies a small area, supporting horizontal and vertical dual installation methods. It is convenient to match various types of vegetable cleaning equipment with flexible layout and strong equipment compatibility.
⑦ Maintenance-Free & Low Operating Cost
Brushless, beltless, gearless and lubricant-free structural design eliminates daily maintenance of wearing parts. The daily operation only needs regular filter cleaning, which greatly reduces later maintenance time and operating cost of vegetable cleaning production lines.
⑧ High Humidity Corrosion Resistance & Long Service Life
The whole machine adopts aluminum alloy die-cast shell and corrosion-resistant coating, with precision dynamically balanced impeller and high-quality wear-resistant bearings. It can operate stably for a long time in high-humidity and water-vapor-rich vegetable cleaning workshops, with strong environmental adaptability and long service life.
