Fine Fiberglass, Precision Filtration: Pocket-Type Medium Air Filters

The Pocket-Type Medium Air Filter delivers reliable medium-stage filtration for air conditioning systems using filter media manufactured from extremely fine fiberglass — a material chosen for its high filtration efficiency, low resistance, and excellent structural stability. The filter media can be selected according to the specific requirements of each application, and filters can be customized in different specifications and models per user requirements — ensuring every system receives a medium filter precisely matched to its airflow, space, and performance needs.

Extremely Fine Fiberglass Media
The filter media is manufactured from extremely fine fiberglass — providing high filtration efficiency for medium particles, low airflow resistance, and excellent structural stability.
Pocket (Bag) Design — Large Filtration Area
The multi-pocket construction provides a large filtration area within a compact footprint — maximizing dust-holding capacity and extending service intervals.
Selectable Filter Media per Requirements
The filter media can be selected according to the specific requirements of each application — efficiency class, dust-holding capacity, and media characteristics matched to the system.
Customizable Sizes & Models
Filters can be customized in different specifications and models per user requirements — ensuring a precise fit for every air handling unit and cleanroom system.
Medium-Stage Filtration for AC Systems
Designed for the medium stage of air conditioning systems — capturing medium particles that pass the primary stage and protecting downstream HEPA filters.
Durable Construction
The filter is constructed with galvanized steel or aluminum frames and robust fine fiberglass media — providing structural stability and reliable long-term performance.
Wide Application
Suited to cleanroom air systems, air handling units (AHU), HVAC equipment, pharmaceutical facilities, and electronics plants.

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.
