Oltaven paint mist filters are finished, dry-type filtration units designed to capture overspray paint particles in spray booths. They combine a flame-retardant kraft paper honeycomb structure with a high-capacity design to trap 95%+ of paint mist, making them ideal for automotive refinish, furniture coating, and general industrial painting. Oltaven manufactures these filters in Zhongshan, Guangdong, China, and supplies them as complete, ready-to-install solutions.
A paint mist filter is more than just filter media; its performance is determined by how the media is pleated, framed, and sealed. Oltaven selects flame-retardant kraft paper as the base material because it offers a balance of strength, fire safety, and paint-holding capacity. The paper is formed into a labyrinth-like honeycomb structure that creates a tortuous path for the air, forcing paint particles to collide and adhere to the surfaces. This forming process—pleating and shaping—maximises the available surface area and ensures that the filter can hold a large volume of paint without a rapid increase in resistance.
The finished filter also includes a sturdy frame that maintains the structure under airflow, preventing channeling or bypass. Sealing is critical to prevent paint-laden air from escaping around the filter edges. Oltaven’s manufacturing process integrates these elements to deliver a product that consistently achieves high efficiency, low resistance, and long service life.
Three key factors determine the performance of a finished paint mist filter: media choice, forming, and sealing. The media must have the right porosity and surface characteristics to capture paint particles while allowing air to pass. Oltaven uses flame-retardant kraft paper that is specifically treated to resist paint penetration and maintain structural integrity. The forming process—how the media is pleated and assembled—affects the filter’s efficiency and capacity. Oltaven’s labyrinth honeycomb design increases the path length for air and particles, enhancing capture efficiency to over 95%. The sealing and framing ensure that all air passes through the filter media, preventing bypass and maintaining consistent performance.
Additionally, the filter’s resistance to airflow is carefully managed. Oltaven’s design allows resistance to rise slowly as paint accumulates, ensuring stable exhaust volume and reducing the load on the booth’s fan system. This is in contrast to traditional filters that may clog quickly and cause a sharp drop in airflow.
Oltaven paint mist filters are suitable for a wide range of spray painting operations. They are particularly effective in automotive body shops and refinishing lines, furniture painting facilities, and mechanical equipment coating workshops. The filters excel in dry filtration setups, especially when dealing with high-viscosity paints such as waterborne paints and clear coats. They can be used as a primary pre-filter in VOCs abatement systems, often combined with medium-efficiency filter mats and activated carbon units to achieve comprehensive emission control. The modular design allows for easy integration into existing booth exhaust systems.

To discuss your paint mist filtration requirements, please contact Oltaven with details of your device or vehicle model, required size or drawing, airflow or water flow rates, operating conditions, and estimated quantity. Our team will respond with a tailored solution. Contact us to get started.
Resistance depends on the filter media, pleat design, and how paint accumulates. Oltaven’s labyrinth honeycomb structure allows a slow, steady rise in resistance, maintaining stable airflow, while conventional filters may clog quickly and cause a sharp pressure drop.
It begins with your specifications: booth dimensions, paint type, airflow, and any constraints. Oltaven’s engineers then propose a filter configuration, provide samples for validation, and upon approval, move to production. The entire process is collaborative and tailored to your needs.
Oltaven paint mist filters achieve an interception rate of 95% or higher, ensuring effective capture of overspray particles. This high efficiency is maintained throughout the filter’s life due to the labyrinth structure that traps particles within the media.
Yes, Oltaven provides samples for testing on your actual spray line. Simply share your requirements, and we will supply standard or custom samples to help you verify performance and fit.
For standard sizes, MOQ is typically 50–100 pieces; custom sizes start at 100–200 pieces. Lead time for standard products is 7–15 days, while custom orders usually take 25–35 days, depending on complexity.
Replacement is recommended when the pressure drop reaches 2–2.5 times the initial resistance, or when visible paint saturation occurs. Under normal conditions, filters last 1–3 months, depending on paint volume and type.
Yes, Oltaven supports full OEM/ODM customisation, including dimensions, frame materials, media grades, and packaging. Our modular designs can be adapted to fit your specific booth exhaust structure.
Oltaven is certified to ISO 9001, ISO 14001, ISO 45001, and IATF 16949. Products comply with REACH and RoHS, and our CNAS-accredited lab provides test reports for efficiency, capacity, and resistance.
