Electronic Components Workshop: Knokoo FES030 Mini Desktop Smoke Purifier Achieves 92% Odor Elimination Rate in 30 Days

Knokoo FES030 Mini Desktop Smoke Purifier Application Case: Solving the Solving Fume Problem in an Electronic Components Workshop.

I. Client Background

The client is a small and medium-sized enterprise in Suzhou specializing in the production of precision electronic components, primarily supplying surface mount resistors, capacitors, and other components to the consumer electronics and automotive electronics sectors. The workshop has 20 soldering stations, each performing 8 hours of manual soldering daily. The solder wire used produces white fumes containing rosin and flux when it melts at high temperatures.

Previously, the client did not have professional fume purification equipment, relying solely on industrial exhaust fans on the workshop ceiling for ventilation. However, the high density and rapid diffusion of the fumes meant the exhaust fans could not effectively remove the fumes near the workstations, forcing soldering workers to work in an odorous environment for extended periods. Some employees experienced discomfort such as dry, itchy throats and coughs. Furthermore, the drifting fumes adhered to the surfaces of precision components, resulting in two batches of products being returned by the client due to excessive surface stains.

II. Core Customer Needs

1. Targeted solution to localized fume issues at individual welding stations, ensuring rapid capture and purification of fumes in the worker's breathing area;

2. Compact equipment size, suitable for placement on a desktop or fixed beside the workstation, minimizing space occupation (workstation desktop width only 60cm);

3. Achieved purification standards, effectively eliminating fumes and odors to prevent impacts on employee health and product quality;

4. Low operating noise, minimizing disruption to normal workshop communication (daily workshop noise level controlled below 50 decibels).

III. Solution: Customized Knokoo FES030 Mini Desktop Smoke Purifier Application Solution

Based on the client's workstation scenario and needs, we recommended and customized a solution using the Knokoo FES030 mini desktop smoke purifier. The specific implementation details are as follows:

1. Equipment Selection and Adaptation: The FES030 model was selected. Its dimensions are only 32cm × 20cm × 28cm (length × width × height), and it weighs approximately 3.5kg. It can be placed directly in a corner of the welding workstation, occupying only about 0.06㎡ of space, perfectly meeting the client's requirements for equipment size. It also features a 360° adjustable flexible smoke extraction arm (80cm in length), allowing workers to flexibly adjust the angle of the smoke extraction port according to the welding position, ensuring that smoke is accurately captured as soon as it is generated.

2. Purification System Configuration: The FES030 is equipped with a triple purification system: pre-filter + HEPA H13 high-efficiency filter + activated carbon adsorption. The pre-filter removes large particles such as solder particles and dust. The HEPA H13 filter achieves a filtration efficiency of 99.97% for smoke particles larger than 0.3μm. The activated carbon filter adsorbs rosin odor molecules. This triple filtration ensures that the exhaust air is free of visible smoke and noticeable odors.

3. Optimized Operating Parameters: Addressing customer noise requirements, the FES030 features a silent fan design, operating at only 45-50 decibels (equivalent to normal conversation). Even with 20 units operating simultaneously, the overall workshop noise level remains below 62 decibels, ensuring uninterrupted production and communication. The equipment also supports three fan speed settings; setting two is sufficient for smoke purification during soldering operations. Daily power consumption is only 0.8 kWh, balancing purification effectiveness with energy efficiency.

4. Installation and Training: Engineers will be arranged to install and debug the equipment, demonstrating the adjustment method of the fumigation arm and the filter replacement procedure (the filter lifespan is approximately 3 months; replacement is simple, requiring only opening the side cover of the equipment) to workers at each workstation. A daily maintenance manual will be provided to ensure the customer can independently perform equipment operation and maintenance.

IV. Cooperation Results

The customer deployed Knokoo FES030 small desktop fumigation purifiers at all 20 welding workstations. After 30 days of operation, significant results were achieved:

1. Smoke and Odor Purification Effect: Visible smoke near the welding workstations in the workshop completely disappeared. Third-party testing showed that the particulate matter concentration in the worker's breathing area (1.5m height from the workstation) decreased from 0.8mg/m³ to 0.08mg/m³, the odor elimination rate reached 92%, and employee feedback indicated that symptoms such as dry throat, itchy throat, and coughing were completely relieved. Workshop work environment satisfaction increased from 58% to 95%.

2. Improved Product Quality: The issue of product appearance stains caused by smoke adhesion has been completely resolved. The subsequent 15 batches of products all passed customer appearance inspection, increasing the pass rate from 92% to 100%. There were no more returns due to stains, directly reducing economic losses by approximately 30,000 RMB per month.

3. Equipment User Experience: The 20 machines operated stably without any malfunctions. Workers reported that the smoke extraction arms were flexible and did not interfere with welding operations; the equipment operated with low noise, causing no disruption to production; filter replacement was convenient, requiring only one hour per month to check and replace the filters on all 20 machines, resulting in low maintenance costs.

Customer Testimonial: "The Knokoo FES030 completely solved our workshop's welding fume problem. The device is compact and doesn't take up much space, and the purification effect exceeded our expectations.
