High Efficiency Air Filter (HEPA) | Sodium-Flame Tested | Cleanroom Grade

Sub-Micron Purity, Proven Per Unit: High Efficiency Air Filters (HEPA)

The High Efficiency Air Filter (HEPA) is primarily used to capture particulate dust below 0.5 µm and various suspended particles — the fine contaminants that threaten cleanroom air quality. Manufactured with ultrafine fiberglass paper as the filter media and offset paper, aluminum foil, or similar materials as separators, the filter is bonded together with a wooden frame and aluminum alloy to form a rigid, leak-resistant structure. Every unit is tested by the sodium-flame method, delivering high filtration efficiency, low resistance, and high dust-holding capacity — widely applied in various local purification equipment and cleanroom plants for ambient air purification under normal temperature, humidity, and pressure conditions.

Sub-0.5µm Particle Capture
Primarily captures particulate dust below 0.5 µm and various suspended particles — the fine contaminants that threaten cleanroom air quality.
Ultrafine Fiberglass Paper Media
The filter media is manufactured from ultrafine fiberglass paper — providing high-efficiency capture of sub-micron particles with excellent structural stability.
Separator Construction for Uniform Pleating
Offset paper, aluminum foil, or similar materials serve as separators between the pleats — maintaining uniform pleat spacing for consistent airflow and filtration performance.
Wooden Frame + Aluminum Alloy Bonded Construction
The media pack is bonded with a wooden frame and aluminum alloy — forming a rigid, leak-resistant structure that maintains integrity in service.
Per-Unit Sodium-Flame Testing
Every filter unit is tested by the sodium-flame method — verifying filtration efficiency and integrity before delivery.
High Efficiency, Low Resistance & High Dust-Holding
The optimized construction delivers high filtration efficiency, low airflow resistance, and high dust-holding capacity — balancing performance, energy, and service life.
Wide Application in Normal Conditions
Widely applied in various local purification equipment and cleanroom plants for ambient air purification under normal temperature, humidity, and pressure conditions.

Applications:

Sinopek is a high-tech provider of comprehensive cleanroom engineering solutions, originating in China and serving a global clientele. For over two decades, we have focused on delivering one-stop, turnkey engineering services that span the entire project lifecycle—from conceptual design to lifelong maintenance. We are not merely builders of physical spaces; we are strategic partners deeply committed to ensuring process reliability, operational efficiency, and regulatory compliance for our clients.

Our Core Strengths: Integrated Delivery and Full-Lifecycle Support

We recognize that a successful cleanroom project is far more than an assembly of equipment and construction materials; it is a systematic engineering endeavor that spans the facility's entire lifecycle. Sinopek creates unparalleled value for clients through four core pillars:

Precise, Forward-Looking Consultative Design
Our design team—comprising process experts, HVAC engineers, and registered architects—adheres strictly to the principle that "process requirements drive design." We are not only well-versed in the highest international and domestic standards (such as ISO, GMP, and FDA) but also possess deep expertise in the specific requirements of sectors like semiconductors, lithium batteries, biopharmaceuticals, and medical devices. From the initial planning stage, we comprehensively address energy efficiency, cost control, and flexibility for future expansion. By proactively mitigating potential risks, we lay the foundation for optimal total-cost-of-ownership for our clients.

Reliable, Efficient Modular Manufacturing and Global Delivery
We take pride in seamlessly blending the modular concepts of "German precision engineering" with the supply chain efficiency of "Smart Manufacturing in China." All core components are precision-prefabricated and pre-assembled on automated lines within Sinopek’s own modern, clean-standard factories, undergoing "zero-defect" factory inspections that exceed ISO 9001 requirements. Supported by a global digital logistics network, we ensure that every shipment reaches project sites worldwide safely, on time, and under controlled conditions. This enables "install-upon-arrival" capabilities, significantly shortening construction timelines.

Professional On-Site Installation Across Borders
Sinopek possesses mature global project delivery capabilities. We have assembled an international project management force that combines a technical core of senior Chinese engineers with local professional teams to ensure successful implementation. Leveraging our proprietary "Cloud-based Project Management Platform" and a deep understanding of local regulations and culture, we efficiently coordinate resources and overcome the challenges of overseas construction. We ensure the precise, "right-first-time" execution of every project and guarantee successful passage of the strictest local third-party verifications.

Smart, Responsive Full-Lifecycle Services
Our service commitment begins after project delivery. Utilizing IoT technology and the "Sinopek Cloud Service" platform, we provide clients with 24/7 remote monitoring, preventive maintenance, and big-data-driven energy efficiency analysis. Whenever and wherever issues arise, our engineers respond immediately with comprehensive solutions—ranging from online diagnostics and rapid spare-parts delivery to on-site support—to ensure the continuous stability and regulatory compliance of the client's production environment, ultimately securing long-term asset value and worry-free operations.
