Aluminum Frame HEPA Filter Without Partition
Aluminum Frame HEPA Filter Without Partition is a high-efficiency air filter with an aluminum alloy frame, eliminating traditional glass fiber separators.
It uses hot-melt adhesive to separate the filter media, resulting in a more compact and lightweight structure. It features high filtration efficiency, effectively capturing fine particles such as dust, smoke, and microorganisms in the air. It also offers lower air resistance, a large dust-holding capacity, and a longer service life.
It is widely used in places with strict air quality requirements, including cleanrooms, laboratories, hospital operating rooms, and high-end purification equipment, to meet the demand for efficient clean ventilation.
Product Introduction
Products Description
Aluminum Frame HEPA Filter Without Partition is a high-efficiency air filtration unit that uses ultra-fine glass fiber as its core filter media and aluminum alloy as its outer frame, adopting a mini-pleated V‑structure without partitions. Its core function is to remove impurities such as 0.1–0.3 μm fine particles, dust, and microorganisms from the air, making it a key final filtration component for creating clean environments.
Product Structure
Aluminum Frame HEPA Filter Without Partition consists of four parts: outer frame, filter media, sealant, and protective mesh.
The outer frame is made of high-strength aluminum alloy profiles with anodized surface treatment, making it corrosion-resistant, aging-resistant, and lightweight, while effectively avoiding deformation and damage during transportation and installation.
The filter media uses high-quality ultra-fine glass fiber with stable filtration efficiency, low resistance, and high dust-holding capacity, maintaining high-performance filtration over an extended period.
Polyurethane sealant is used for seamless sealing to effectively prevent leakage of unfiltered air and ensure reliable filtration performance.
Both the air inlet and outlet sides are equipped with powder-coated metal protective meshes, which protect the filter media from damage and ensure uniform airflow distribution, further enhancing filtration stability.

Product Advantages
High-Efficiency Filtration
It can accurately capture fine particles, microorganisms, and other contaminants, meeting various cleanliness requirements including Class 100, Class 1000, and Class 10000, making it suitable for high-standard clean applications.
Sturdy and Durable
The outer frame is constructed from high-strength aluminum alloy with anodized finishing, providing excellent moisture resistance, corrosion resistance, and anti-deformation performance.
Easy Installation
The filter is thin and compact with a small footprint, suitable for various limited installation spaces. It is convenient and efficient to install, significantly shortening the construction period.
Stable and Reliable
It delivers excellent sealing performance with seamless polyurethane sealant, effectively eliminating air bypass. Uniform airflow distribution ensures stable and consistent cleanroom conditions.
Application Scope
Electronics and Electrical Industry
Semiconductor, LCD manufacturing workshops, and dust-free cleanrooms, used for final supply air filtration to prevent fine dust from affecting product precision and yield.
Medical and Biological Industry
Hospital operating rooms, ICUs, and other sterile environments, used to control microbial contamination and ensure medical safety and product quality.
Food and Beverage Industry
Food processing workshops, baking workshops, and other production areas, removing airborne dust and microorganisms to prevent food contamination and comply with food hygiene and safety standards.
Storage Requirements
Uninstalled filters should be stored in a dry, well-ventilated, and clean environment with a temperature controlled between 10–30°C and relative humidity not exceeding 60%, kept away from chemicals and corrosive gases.
Keep the original packaging intact and avoid early unpacking. Place filters vertically and avoid excessive stacking to prevent aluminum frame deformation and filter media damage.
Establish an inventory management log, follow the first-in, first-out (FIFO) principle, and inspect stored products regularly.
