Shenzhen Snow Peak Clean Technology Co., Ltd. is an integrated high-tech enterprise, specialized in air filtration products research and development, production, sales, import and export trade. We produce and supply a comprehensive suite of solutions including: Pre-filters, pocket filters, HEPA filters, chemical filters, replacement HEPA filters, car cabin air filters, and humidifier filters, alongside pocket filter media and melt-blown composite filter media.
We provide high-quality air purification solutions and products for indoor air pollution control and air conditioning systems across civil and industrial buildings, microelectronics, pharmaceuticals, laboratories, schools, cleanrooms, and hospitals.
Combined with self-developed patented technology, our sterilizing antiviral HEPA filter can effectively filtrate fine particles so that the PM2.5 concentration goes down to 10 micrograms/m³ (which is 5 times better than the national standard). It effectively inhibits the breeding of microorganisms, yielding a sterilization rate up to 99.9% without secondary pollution, and achieves an H1N1 virus removal efficiency as high as 99.99%.
Having 15 years of international air purification technology experience as our background, our company operates a standardized production workshop, dust-free filter workshop, and a first-class technology HEPA filters production line and inspection line. Our independent research and development of fully automatic air filter production lines, equipped with an AMADA CNC punch, CNC bending machine, and other advanced high-end machinery, provides a strong guarantee for the production capacity, precision, and quality of our air filtration and purification products.
In the current global industrial environment, emissions control, gas-phase contaminant management, and airborne molecular contamination (AMC) abatement are highly prioritized. Stricter environmental policies (such as the EU Green Deal, EPA guidelines, and cleanroom air quality ISO regulations) mandate that modern facilities implement multi-stage air purification setups. Among these, the Activated Carbon Vent Filter serves as a critical defense mechanism.
Sterile storage tank venting is vital to prevent ambient microbial and particulate contamination from entering media during liquid transfer. Incorporating CE-certified carbon vent filters prevents volatile organic compounds (VOCs), acidic gases, and airborne biological vectors from breaching bioreactors and holding tanks.
Sub-nanometer silicon fabrication requires the absolute exclusion of organic and chemical trace gases. Ambient molecular compounds can degrade wafers instantly. Our custom multi-stage W-shape filters and impregnated carbon canisters absorb trace cleanroom emissions, neutralizing acidic vapor and solvent compounds.
Wastewater treatment plants, petrochemical storage units, and solvent distribution terminals rely on high-capacity activated carbon vents. By capturing hydrogen sulfide (H₂S), mercaptans, and complex hydrocarbons, our honeycomb carbon arrays control odors and comply with local air quality standards.
An activated carbon vent filter does not simply trap particles mechanically; it relies on molecular adsorption. Through physical van der Waals forces and chemical reactions (chemisorption), gas molecules are drawn into the highly developed micropore network of the carbon substrate.
| Adsorbent Base Media | Typical Iodine Number (mg/g) | Primary Adsorption Profile | Target Industries / Applications |
|---|---|---|---|
| Coal-based Extruded Carbon | 900 - 1050 | Broad-spectrum organic vapors, medium to high molecular weight VOCs. | Chemical storage tanks, bulk solvent vents, wastewater facilities. |
| Premium Coconut Shell Carbon | 1100 - 1250 | Low-concentration microporous capture, trace gas compounds, low-molecular compounds. | Microelectronics cleanrooms, electronics storage cabinets, aerospace. |
| Impregnated Activated Carbon (KOH/NaOH) | 850 - 950 | Acidic gases (SO₂, H₂S, HCl) via chemical neutralization and targeted adsorption. | Chemical manufacturing, acid pickling lines, municipal sewer vent lines. |
| Impregnated Carbon (Phosphoric Acid) | 800 - 900 | Alkaline contaminants, ammonia (NH₃) abatement, organic amines capture. | Fertilizer handling plants, animal husbandry facilities, laboratory exhaust. |
Designing an efficient vent filter assembly requires balancing three primary physical attributes:
As a CE-certified manufacturer, Shenzhen Snow Peak Clean Technology Co., Ltd. ensures that our materials, testing, and production lines satisfy the requirements of international target markets.
Our active carbon and HEPA lines comply with the European Economic Area (EEA) safety, health, and environmental protection standards. By adhering to EN 1822 for high-efficiency filters and ISO 16890 for general ventilation, we guarantee precise air cleaning performance. Our structural housings are constructed using advanced AMADA CNC equipment to withstand high pressurization levels without leaks.
We offer bespoke size customizations, structural flange designs, and optimized carbon blends tailored to local regulations (such as EPA, OSHA, and regional cleanroom codes). Our global distribution network ensures that replacement filters reach our international clients on schedule, minimizing downtime and maintaining uninterrupted industrial operations.
At Shenzhen Snow Peak Clean Technology Co., Ltd., we continuously invest in next-generation filtration media and sustainable production methodologies.
We are researching thermal regeneration processes for spent carbon substrates, allowing customers to reduce their overall footprint and reuse housings, contributing to circular industrial life cycles.
Integrating electrospun polymeric nanofibers with micro-ground carbon crystals to develop high-efficiency particulate and gas-phase filtration in a single, low-resistance layer.
Integrating electronic pressure drop sensors and chemical trace transmitters inside vent assemblies to notify operators when carbon saturation approaches breakthrough threshold levels.
A1: You must calculate the maximum air volume displaced during tank filling (inflow) and the maximum air vacuum during product drawdown (outflow). The vent filter must be sized to handle this flow rate with a minimum pressure drop to prevent the tank from buckling. Contact our technical team to match your specific piping diameter, flow velocity, and chemical composition.
A2: CE certification confirms that the air filtration product complies with relevant European safety and performance standards. It ensures that the structural materials resist chemical degradation, that the filter retains its specified carbon quantity without bypass leakages, and that the filtration medium performs within the claimed parameters.
A3: The lifespan of a carbon filter depends on the gas concentration, ambient temperature, relative humidity, and runtime. The filter must be replaced before it reaches breakthrough point, where the carbon becomes saturated and can no longer capture gases. Regular VOC monitoring at the outlet or using visual color-indicating media helps determine the precise replacement interval.
A4: Standard carbon vent filters cannot be washed, as water blocks the micropore structure and destroys adsorption capacity. Commercial regeneration requires thermal reactivation in specialized industrial kilns at temperatures exceeding 800°C under controlled steam conditions.
A5: We utilize high-hardness extruded or granulated carbon combined with synthetic non-woven polyester containment layers on both the inlet and outlet. This prevents carbon fines from entering clean downstream processes or releasing into the atmosphere.
A6: Yes, we utilize our in-house automated production lines, including AMADA CNC punch and CNC bending machines, to manufacture custom cylindrical and flat-panel housings. We can customize dimensions, connector styles, and materials (such as stainless steel or high-grade polypropylene) to meet your facility requirements.
