High-efficiency primary, secondary, and molecular filters for global cleanroom systems
As an integrated high-tech enterprise, Shenzhen Snow Peak Clean Technology Co., Ltd. specializes in air filtration research, development, production, and global trade. We supply advanced solutions including Pre-filters, Pocket filters, HEPA filters, Chemical molecular filters, and customizable Replacement HEPA/Cabin/Humidifier systems.
Leveraging self-developed patented technology, our sterilizing and antiviral HEPA filters maintain PM2.5 concentrations below 10 micrograms per cubic meter—5 times superior to national standards. Engineered to inhibit microbial growth, they deliver a sterilization rate of 99.9% and an H1N1 virus removal efficiency exceeding 99.99%, without inducing secondary pollution.
Volatile Organic Compounds (VOCs) encompass a wide array of gaseous chemical elements, including aliphatic hydrocarbons, aromatic rings (benzene, toluene, xylene), aldehydes, and chlorinated solvents. Standard particulate filters (HEPA) are incapable of intercepting these molecular gases due to their sub-nanometer dimensions. Molecular adsorption filtration relies on the micro-porous structure of activated carbon.
"The physical adsorption of VOCs onto activated carbon is governed by Van der Waals forces, while reactive gases are captured via chemisorption—wherein an impregnating chemical agent transforms harmful molecules into stable, solid compounds."
Shenzhen Snow Peak utilizes high-grade virgin coal-based or coconut-shell carbon. The activation process yields an internal surface area ranging from 900 to 1,500 m²/g. The pore-size distribution is strictly controlled to ensure high macro-pore volume for gas distribution, alongside micro-pores under 2 nanometers for target VOC entrapment.
Carbon substrates are treated with catalysts (such as KOH, KI, or KMnO4) to chemically neutralize acidic gases, formaldehyde, and volatile amines through chemical conversion.
Our engineered carbon beds are modeled to optimize residence time, maximizing the gas contact interval and extending service life before VOC saturation occurs.
To address rising energy costs and stringent environmental policies, the next generation of molecular air filtration is transitioning toward dynamic, low-pressure-drop composite systems. Traditional granular carbon systems, while highly efficient, often cause significant resistance in HVAC units, driving up energy consumption.
Shenzhen Snow Peak is actively developing ultra-thin carbon-sandwiched non-woven media. These configurations achieve lower initial resistance while ensuring high dust and odor removal efficiency, presenting a sustainable roadmap for green building air management.
Looking to the future, Snow Peak is shifting its active raw materials toward bio-based waste components, such as agricultural sub-products, supporting a lower carbon footprint across all ODM production stages.
Industrial purification needs vary across sectors. A single filter media cannot satisfy every industrial criteria. Shenzhen Snow Peak builds application-specific products engineered to operate in challenging environments.
In microchip lithography, Airborne Molecular Contamination (AMC) can degrade silicon wafers. Our specialized chemical filters target acid vapors, bases, and condensables down to parts-per-trillion (ppt) levels.
Where bio-safety is critical, we supply gel-seal HEPA and Bag-In-Bag-Out (BIBO) safe-change housings to capture toxic particulate agents and neutralize hazardous fumes during operation.
Coating lines generate concentrated solvent emissions and overspray. Combining G4 fiberglass paint-stop rolls with deep-pleated gas-phase filters prevents paint escape and manages exhaust odors.
Providing custom HVAC filtration retrofits, and high-efficiency Honeywell and Coway aftermarket replacement cartridges to combat allergens, pathogens, and VOCs.
Operating out of Shenzhen, the epicenter of advanced cleanroom logistics, Snow Peak leverages a 15,000 m² factory environment. Automated production guarantees product consistency, rapid turnaround, and competitive cost structures.
Equipped with AMADA CNC punch presses and CNC bending machinery, our manufacturing line forms steel and aluminum frames with precise dimensions down to ±0.2 mm. Our fully automated HEPA filter manufacturing line seals pleated media to frames under cleanroom conditions, preventing bypass leakage.
By integrating the production of raw pocket media, melt-blown polymers, and laminated wire meshes in-house, we reduce dependency on external suppliers. This vertical integration ensures a reliable supply chain during global logistic shifts.
Every high-efficiency filter undergoes oil-aerosol scan testing (DEHS/PAO method) in compliance with EN 1822 and ISO 29463 guidelines. We track pressure drop, fractional penetration, and structural integrity, shipping certified products with detailed test reports.
International procurement departments evaluate air filtration suppliers on criteria beyond unit costs. Critical factors include total cost of ownership (TCO), supply chain reliability, compliance documentation, and ODM customization capabilities.
Snow Peak's engineering team coordinates directly with international clients to map out custom specifications. From customized gel-seal terminal HEPA systems for pharmaceutical suites to replacement carbon units for retail air purifiers, we provide comprehensive technical support throughout the product development process.
Undergoing rigorous quality control across every production stage
To supply cleanrooms and critical facilities globally, our products comply with international standards. Shenzhen Snow Peak holds approvals from several global regulatory and certification bodies:
"We maintain absolute compliance with EN 1822:2019 (HEPA standards), ISO 16890:2016 (standardized testing of general ventilation filters), and CE certification protocols, ensuring import viability into all major global markets."
Our active molecular products undergo rigorous gas-phase testing in accordance with ASHRAE 52.2 and ISO 10121, tracking efficiency across various gas challenge concentrations. We offer fire-retardant structural elements rated under UL 900 and guarantee compliance with RoHS and REACH standards for chemical safety.
