Addressing industry pain points such as wastewater generated from traditional water curtain cabinets and the clogging of conventional paint mist cotton, Cleantop has specially launched the Maze-Type Honeycomb Cardboard Paint Mist Filter Box (Dry Paint Mist Collection Box). Utilizing a unique “maze-type inertial collision + interception adsorption” working principle, it forces airflow to change direction multiple times, securing over 95% of paint debris while achieving an extremely high paint capacity. This thoroughly resolves paint exhaust clogging issues, reducing the costs of hazardous waste treatment.
Get the Dry Spray Dust Removal Solution and QuotationUnlike traditional paint mist cotton that is easily clogged by paint debris, the maze-type structure ensures even distribution of paint mist on the deep corrugated cardboard walls. The single box can hold up to 12–18kg of paint (more than 5 times that of traditional filter cotton). After reaching saturation, the increase in air resistance is slow, ensuring balanced airflow in the spray booth without affecting production pace.
Entirely dry physical interception without a water circulation system like that of water curtain cabinets. This fundamentally eliminates the generation of paint debris wastewater, saving on expensive sewage treatment costs. The saturated boxes prevent paint debris from scattering and can be directly packed for hazardous waste compliant disposal, making environmental compliance easier.
Using special flame-retardant treated cardboard, it can withstand high-temperature conditions of spray booths, significantly reducing fire risks. With a paint mist interception rate as high as 95%, it perfectly protects backend fan impellers and activated carbon boxes from being clogged, reducing electricity costs and maintenance costs for enterprises.
| Performance Comparison Items | Cleantop Maze-Type Honeycomb Filter Box | Traditional Paint Mist Cotton (Fiberglass/Non-Woven) | Traditional Water Curtain Cabinet (Wet-Type) |
|---|---|---|---|
| Filtration Efficiency | High (95%+, efficiency increases as passages narrow) | Average (initially high, easily penetrated over time) | Moderate ( prone to water mist and secondary pollution) |
| Paint Capacity and Lifespan | Very High (12-18kg/box, longer replacement cycle) | Very Low (prone to surface skin blockage) | Frequent shutdown needed to collect paint debris wastewater |
| Air Resistance and Airflow Impact | Air resistance rises slowly, does not affect exhaust volume | Air resistance rises rapidly, exhaust volume drops sharply | Significantly affected by scale and paint debris, unstable resistance |
| Environmental Protection and Hazardous Waste Treatment | Zero wastewater, cardboard packaged for compliant disposal | Risk of fiber shedding pollution | Wastewater likely to exceed standards, bad odor promotes bacterial growth |
| Overall Operating Cost | Very Low (no water/sewage fees, easy replacement) | Relatively High (very frequent material replacement) | Extremely High (expensive water fees + hazardous waste disposal fees) |
| Applicable Core Scenarios | Automotive body spray booths, furniture spray booths, machinery coating workshops, etc. Especially suitable for dry treatment of water-based paints, varnishes, and other high-viscosity paint mists. |
|---|---|
| Best System Match | Often used as "primary pre-filtering" for VOC waste gas treatment, combined with medium-efficiency filter cotton + activated carbon box for dual compliance of “paint mist + odor” emissions. |
| Product Customization Capability | Backed by a 50,000㎡ factory and a CNAS laboratory, certified by ISO/IATF16949. Supports modular-sized OEM/ODM customization according to the structure of the spray booth's exhaust section. |
Are you still worried about the high wastewater treatment fees and frequent clogging of filter cotton in water curtain cabinets? With over 20 years of industrial air filtration experience, Cleantop provides you with an easy-to-install, environmentally compliant dry paint mist capture solution.
Contact a Senior Engineer / Get Samples and Solutions for FreeCleantop offers a complete paint mist filtering solution, which mainly includes: Fiberglass Paint Stop, Paper Venturi Paint Arrestor, ground cotton (bottom cotton), and ceiling filter. These products are widely used in spray lines for complete vehicles and components, furniture spraying, construction machinery, hardware coating, and general industrial spray booths, effectively capturing overspray paint mist particles, protecting downstream equipment, and improving workshop environments. Specific models can be recommended based on your spraying process (water-based paint/oil-based paint/high solid content paint).
The paint mist capture efficiency of Cleantop paint mist filters can reach 98%-99% (tested according to ASHRAE 52.1 or EN 779 standards), with paint capacity usually reaching 8-15 kg/m²; specific figures can vary based on product type and testing conditions. All performance data is certified by our nationally recognized CNAS testing center, ensuring accuracy and traceability, providing customers with reliable selection basis.
Yes. Cleantop has over 20 years of experience in customized production and supports full customization of dimensions, thickness, weight, fold count, frame materials (paper frame/metal frame/frame-less), and packaging (neutral packaging, customer branded packaging, colored boxes, etc.). We have a professional R&D team that can develop tailored solutions based on the customer's spray booth structure, wind speed, and process requirements, and provide sampling and validation services.
Cleantop has obtained ISO 9001, ISO 14001, and ISO 45001 management system certifications, and in 2024, we will acquire IATF 16949 automotive industry quality management system certification and GMP certification for medical supplies, fully meeting compliance requirements for automotive OEM and Tier 1/Tier 2 suppliers. Additionally, our products have obtained various international certifications such as Europe's BSC1, the US EPA, NSF, etc., and are exported to markets including Europe, the United States, Japan, and South Korea.
Cleantop is located in Zhongshan, Guangdong, with a 50,000㎡ factory and 20,000㎡ (6) clean workshops, capable of large-volume stable delivery. In terms of quality control, we have established a comprehensive quality control system that covers everything from raw material inspection, production process inspection to finished product delivery. We also rely on the national CNAS recognized testing center for full testing of key indicators such as filtration efficiency, resistance, paint holding capacity, and combustion grade, ensuring consistent product performance and reliable quality in every batch.
The MOQ for standard specification products is generally 50-100 pieces, while the MOQ for customized specifications depends on structural complexity, usually starting from 100-200 pieces. We can negotiate flexibly for new customers and sample orders. Standard products typically have a delivery time of 7-15 days, while bulk orders for customized products usually take 25-35 days. The company has multiple automated production lines and sufficient raw material supplies to support urgent orders and long-term stable supply needs.
Yes. Cleantop welcomes customers to conduct sample tests prior to mass procurement. We can provide standard samples for customers to test in actual spray lines, and our CNAS laboratory can also assist in providing third-party testing data and technical support to help customers quickly complete their selection and validation process.
It is usually recommended to judge the replacement timing based on pressure difference (when the final resistance reaches 2-2.5 times the initial resistance) or visual inspection (when the filtering medium is obviously saturated or paint mist penetration occurs), with a general lifespan of 1-3 months depending on the spraying volume. Cleantop has accumulated thousands of filter solutions over 20 years in the industry, and our professional engineering team can provide customers with selection consultation, installation guidance, lifespan assessment, and overall optimization suggestions for spray booth filtration systems to ensure that customers achieve the best usage effects and lowest overall costs.
