3. Key Features & Benefits

3.1 Superior Liquid-Tank Sealing Performance

The top liquid-tank design creates a continuous, form-fitting seal around the filter blade. The blue jelly glue fills the tank, completely enveloping the blade edge and eliminating any air bypass. This design outperforms traditional gasket seals, especially under variable pressure conditions, and provides long-term sealing stability without compression set.

3.2 High Filtration Efficiency (H14 Class)

Utilising premium glass fibre filter media, this filter achieves H14 efficiency – 99.995% to 99.999% removal of particles at 0.3μm (MPPS). It is ideally suited for ISO Class 5 (Class 100) and higher cleanroom environments where ultra-clean air is essential.

3.3 High Dust-Holding Capacity & Extended Service Life

The pleated media structure, maintained by precision hot-melt glue separators, maximises the effective filtration area. This results in significantly higher dust-holding capacity compared to standard filters, translating to longer service intervals and reduced replacement frequency – lowering total cost of ownership.

3.4 Low Resistance & Energy Efficiency

Despite its high efficiency, the filter maintains a low initial pressure drop, reducing the energy consumption of downstream fans or FFU systems. This is particularly beneficial in large-scale cleanroom installations where hundreds or thousands of filters operate continuously.

3.5 Lightweight & Easy Installation

The aluminium alloy frame is both lightweight and robust, simplifying handling and installation. The filter inserts directly into the top liquid tank with minimal effort, and the jelly glue automatically conforms to the blade, creating an instant airtight seal.

3.6 Reliable Quality Assurance

Every filter is 100% leak-tested using a particle counter scan method prior to shipment. This ensures that no pinhole leaks, media defects, or seal failures compromise the filter's performance.

These filters adhere to industry standards and regulations to guarantee optimal performance in removing contaminants and providing a safe air quality environment.

Regular testing and certification of ULPA filters are necessary to ensure they meet air quality standards and continue to perform effectively. By monitoring and replacing ULPA filters as needed, industries can maintain high air quality standards and create a safe and clean working environment for their employees.
ULPA filters are constructed with advanced technology and materials to achieve their exceptional filtration capabilities. These filters consist of densely packed fibers or membranes that create a labyrinthine pathway for air to pass through. As the air travels through the filter, particles are trapped and captured by the fibers, preventing them from circulating back into the environment.

The design of ULPA filters ensures that they can capture particles down to the size of 0.12 microns with an efficiency of 99.9999%. This level of filtration is unmatched by standard HEPA filters, making ULPA filters the top choice for industries that require the highest level of air purity. The filters undergo rigorous testing to confirm their efficiency in removing contaminants, and they must meet strict standards to be certified as ULPA filters.

In critical environments such as cleanrooms and laboratories, the use of ULPA filters is essential to prevent contamination and ensure product integrity. By maintaining clean air quality through the installation of ULPA filters, industries can protect their processes, products, and personnel from potentially harmful particles and microorganisms. The ongoing monitoring and maintenance of ULPA filters play a crucial role in upholding air quality standards and safeguarding the integrity of controlled environments.
What does a HEPA filter do?

A HEPA (High Efficiency Particulate Air) filter is a type of air filter that is highly effective at capturing and trapping microscopic particles such as dust, pollen, mold spores, pet dander, bacteria, and even viruses. HEPA filters are designed to remove at least 99.97% of particles that are 0.3 microns in size or larger.

HEPA filters work by forcing air through a fine mesh made of randomly arranged fibers. As air passes through the filter, particles are trapped by a combination of mechanisms, including interception, impaction, and diffusion. This process ensures that even the smallest and most harmful particles are captured and prevented from circulating back into the air.

HEPA filters are widely used in HVAC systems, air purifiers, vacuum cleaners, and other air filtration devices to improve indoor air quality and create a healthier environment. They are especially beneficial for individuals with allergies, asthma, or respiratory conditions, as they can help reduce exposure to airborne pollutants and irritants.

Overall, the primary function of a HEPA filter is to efficiently remove harmful particles from the air, leading to cleaner and fresher indoor spaces and promoting better respiratory health for occupants.
