Explore our selection of heavy-duty pre-filters, high-efficiency HEPA solutions, and specialized customized antibacterial media designed to support international air purification architectures.
Shenzhen Snow Peak Clean Technology Co., Ltd. stands as an integrated, high-tech engineering enterprise specializing in high-performance cleanroom equipment, air filtration media research and development, smart manufacturing, and comprehensive export services. For over 15 years, our technical directors have focused on structural engineering of non-woven materials, synthetic micro-fiber lamination, and biological decontamination systems to develop elite pre-filtration solutions.
Our research lab has engineered pioneering sterilizing antiviral HEPA filtration media, capable of optimizing indoor environmental safety by maintaining PM2.5 levels below 10 micrograms per cubic meter—exceeding key national hygiene baselines by up to 5 times. Our patented sanitization matrix yields an active bacterial control rate of 99.9% and an H1N1 viral containment efficiency of up to 99.99%, removing secondary pollution pathways in commercial HVAC networks.
"Through meticulous polymer engineering and progressive density thermal bonding, our G4 filter materials ensure minimal resistance, maximized dust-holding capacity (DHC), and reduced operational energy costs."
An in-depth look at coarse dust pre-filtration performance metrics under global testing methodologies such as ISO 16890 and EN 779:2012.
Our G4 filter materials utilize premium thermobonded synthetic fibers designed with a progressive density matrix. This dynamic composition allows particles to penetrate deep into the material rather than immediately clogging the outer layer, boosting Dust Holding Capacity (DHC) to values exceeding 450g/m² under standard test conditions.
Under the European standard EN 779:2012, our G4 material retains an average arrestance of synthetic dust (Am) greater than 90%. When cross-evaluated under the newer ISO 16890 classification system, this material aligns with the ISO Coarse 60% to 90% classifications, depending on media weight and configuration (e.g., 200g/m² up to 400g/m²).
By optimizing fiber diameters and structuring the needle-punched layers, we reduce initial pressure drop to as low as 25 Pa at standard face velocities (1.5 m/s). This direct pressure minimization lowers HVAC energy consumption, helping operators meet sustainability standards and reduce overall energy costs.
Analyzing the shift in high-volume pre-filtration sourcing within the context of automated manufacturing, sustainability directives, and smart buildings.
Modern HVAC procurement managers are moving away from commodity-based, single-source pre-filters toward engineered G4 media roll goods and pocket filters that feature customized dimensions, flame retardancy (UL 900 Class 1 or Class 2), and integrated synthetic wire-mesh support. The global focus on indoor air quality (IAQ) and ESG metrics requires pre-filtration materials to maximize lifetime efficiency to safeguard expensive downstream HEPA stages.
Additionally, localized supply chains demand high performance under varied humidity levels and industrial chemical exposures. As a result, sourcing agents prioritize ODM exporters who provide robust material tracing, CE-certified configurations, and custom dimensions that reduce shipping waste.
Our manufacturing floor integrates advanced machinery to achieve precise thickness, clean cuts, and consistent media weight across all G4 rolls, panels, and synthetic media bags.
Custom ODM solutions designed to handle high dust loads in commercial building ventilation systems, automotive spray painting booths, and heavy industrial facilities.
By using synthetic wire-mesh laminated rolls and pleated pre-filter frames, building managers can optimize IAQ while maintaining low system resistance. Our G4 filters serve as a primary line of defense, intercepting airborne particulates such as pollen, lint, and micro-debris before they reach secondary or tertiary bag and HEPA filtration stages.
Automotive spray painting operations require particulate-free airflow to avoid coating defects. We supply 600g ceiling filter cotton (G4/M5 efficiency class) and specialized fiberglass paint stop floor air filter rolls. These materials intercept fine paint overspray while sustaining balanced air distribution across the baking and curing enclosures.
Cleanroom environments rely on primary filters to extend the service life of ultra-high-efficiency HEPA and ULPA filters. Our washable aluminum metallic mesh filters and high-performance synthetic G4 pocket filters provide cost-effective pre-filtration, capturing heavy atmospheric dust and reducing cleanroom downtime.
By leveraging 15 years of air purification expertise, we support every phase of production with advanced manufacturing technology. Our frame fabrication relies on high-speed AMADA CNC punch systems to ensure clean folds and consistent sizing for large commercial ventilation orders.
Quality control is central to our operations. Every batch of G4 filter media, whether provided in rolls or fabricated as pleated filters with cardboard, aluminum, or galvanized steel frames, undergoes standardized quality checks. These tests verify structural integrity under high air volumes, consistency in weight, and compliance with the EN 779 and ISO 16890 testing standards.
How we are engineering the next generation of eco-friendly G4 materials to support global net-zero carbon goals.
Our research and development team is testing biodegradable polymers derived from renewable resources. These bio-based synthetic G4 fibers deliver comparable tensile strength and temperature stability to traditional petroleum-based media, reducing environmental impact at the end of the filter's service life.
Unlike standard mechanical separation media, our upcoming electrostatically charged coarse filtration layers attract and hold sub-micron dust particles without increasing flow resistance. This dynamic allows the material to function effectively as a G4 pre-filter while capturing fine PM2.5 particulates at lower resistance levels.
Through our advanced manufacturing systems, we can produce pre-cut panels customized to client specifications, minimizing media scraps during on-site installation. This service reduces material waste, lowers shipping weight, and simplifies installation for maintenance technicians in commercial and industrial settings.
Exporting industrial filtration components requires strict compliance with international customs, environmental regulations, and local safety standards. As an experienced ODM exporter, Shenzhen Snow Peak Clean Technology Co., Ltd. ensures that our G4 materials, pocket filters, and HEPA units meet all key global benchmarks.
Our dedicated logistics department coordinates door-to-door delivery, customs clearance, and container optimization to ensure efficient shipping and minimize freight costs. We provide standard testing documents, Certificates of Origin (CO), and detailed technical datasheets with every shipment to streamline the import process for global buyers.
