The Core Difference Between Industrial Oil Mist Collectors and Commercial Kitchen Air Cleaners

Scope of Application

The scope of application is the fundamental difference between the two. The core difference lies in the different scenarios and types of pollution generated by the target to be purified, which directly determines the design direction of the equipment.

1. Industrial Oil Mist Collectors:

Industrial oil mist collectors are highly targeted at industrial CNC machining applications, specifically targeting pollutants generated during the operation of machining centers, cleaning equipment, and CNC machine tools. Its targets are not everyday cooking fumes, but welding fumes and dust generated during cutting, lubrication, and cooling processes, as well as industrial oil mist containing nitrogen compounds and benzene.

In terms of its value, it not only mitigates the health risks of industrial oil mist to frontline workers, but also improves the production workshop environment, preventing smoke-laden air from affecting product processing precision. It also protects the manufacturer's circuit systems, indirectly reducing economic losses.

2. Commercial Kitchen Air Cleaners:

Commercial kitchen air Cleaners are more applicable to daily life and some industrial auxiliary areas, primarily targeting cooking and heating fumes. They cover a wide range of scenarios, including kitchens in hotels, restaurants, schools, and government agencies, as well as food frying and cooking processing workshops. Furthermore, within industrial settings, they are also suitable for oil spray heat treatment workshops, oil mist lubrication workshops, workpiece welding workshops, and oil pan exhaust.

Unlike industrial oil mist collectors, their core goal is to ensure that oil fume emissions meet my country's catering industry oil fume emission standards, addressing the pollution of oil fume to the air environment and its impact on the human body.

Pollutant Characteristics

Differences in pollutant composition, particle size, and morphology determine the different purification objectives of the two types of equipment:

1. Industrial Oil Mist Collectors:

The oil mist they handle consists of pure liquid oil droplets, primarily cutting oil and emulsions. The particle size is finer (0.1-5μm) and free of complex odors. The core requirement is to efficiently capture oil mist particles to prevent them from adhering to machine tool guideways and lenses, affecting precision, or from being inhaled by workers and causing health problems.

2. Commercial Kitchen Air Cleaners:

The oil fumes they handle are a mixture of oil mist particles, volatile organic compounds (VOCs), and odors. Oil mist particles are mostly 1-10μm in size and contain VOCs such as aldehydes and ketones produced by the high-temperature decomposition of cooking oil, as well as pungent odors from cooking. Purification requires the dual objectives of particle and odor removal.

Basic Principles

The operating principle is the core of the equipment's purification function. Due to the different physical characteristics of the purification targets (such as particle size and composition), the two types of equipment employ completely different technical approaches.

1. Industrial Oil Mist Collector:

The core technology of industrial oil mist collectors is separation followed by filtration. To address the potential mixture of oil, water, and dust in industrial oil mist, they utilize negative pressure separation technology.Using negative pressure, the oil and water mist generated by the CNC lathe is forcibly drawn into the device. The density differences between oil, water, and air achieve initial separation. The separated oil and water are then returned to the cutting fluid tank through a dedicated drainage pipe for resource recovery and reuse.

However, given that oil mist may contain large dust particles in industrial applications, the device can also be equipped with a post-installed three-dimensional mesh filter. This filter increases the filtration space and utilizes the interception effect of its mesh structure to completely block harmful large particles from entering the separation system, preventing them from affecting purification efficiency or causing equipment clogging.

2. Commercial Kitchen Air Cleaners:

The technical principle of commercial kitchen air Cleaners is to first capture and then filter. Taking advantage of the small and easily diffused oil mist droplets in restaurant cooking fumes, they utilize the principle of electrostatic adsorption.

When the oil mist airflow enters the equipment, it first passes through a pre-filter, which intercepts larger oil mist droplets and oily particles, achieving initial purification. The purified airflow then enters a high-voltage electrostatic field. The strong electric field ionizes the oil mist, and the tiny oil mist particles become charged. The electric field attracts them to the electrode plates, where they accumulate and flow into the oil collection pan.

In summary, for restaurant operators who need to deal with oil fumes and odors while complying with local restaurant environmental protection requirements, commercial kitchen air Cleaners are recommended. For industrial processing companies that need to deal with pure oil mist particles generated by CNC machine tools to protect equipment precision and worker health, industrial oil mist collectors are recommended. Select the appropriate type based on the oil mist concentration. Choosing the right equipment is the first step to environmental compliance, cost reduction and efficiency improvement. Confusing the two types of equipment will not only lead to purification failure, but may also result in environmental penalties. Accurate matching is required based on your own scenario.
