With the revival of the catering industry, small restaurants face the crucial task of choosing the right electrostatic precipitator. First and foremost, ensuring compliance with environmental inspections is non - negotiable. For small eateries, typically equipped with one or two stoves, a low - altitude electrostatic precipitator with an air volume of 8000 - 12000 is recommended, as it offers efficient purification for low - altitude emissions, minimizing complaints from neighbors and keeping the kitchen clean. In areas with stricter requirements, a higher air volume may be needed. After installation, thorough checks on purification effect, noise, and grounding are essential. By making these smart choices, small restaurants can meet environmental standards while ensuring safe and smooth operations.
