High-Temperature HEPA filters

Clean-Link supplies high-temperature HEPA filters for industrial and critical applications where both thermal resistance and air cleanliness are essential.

What Are High-Temperature HEPA Filters?

High-temperature HEPA filters are specialized high-efficiency air filters constructed with heat-resistant media, frames, separators, and sealants.

Unlike standard HEPA filters used in HVAC systems, these filters are designed to operate at elevated temperatures without degradation of filtration efficiency or mechanical stability.

They are typically installed downstream of high-temperature processes or sterilization stages where airborne particulate control remains critical.

Key Performance Characteristics

High-temperature HEPA filters are designed to provide:

• High particulate removal efficiency under elevated temperatures

• Stable pressure drop during thermal exposure

• Structural integrity at sustained high operating temperatures

• Reliable sealing to prevent air bypass

• Compatibility with high-temperature air handling systems

Performance limits depend on filter design, materials, and application conditions.

Typical Applications

High-temperature HEPA filters are commonly used in:

• Pharmaceutical and biotechnology sterilization processes

• Industrial drying ovens and heat treatment systems

• Cleanroom exhaust or recirculation systems exposed to heat

• Chemical processing and thermal exhaust applications

• Specialized manufacturing processes requiring sterile hot air

These applications demand both contamination control and resistance to thermal stress.

Materials and Construction Options

Clean-Link high-temperature HEPA filters can be configured with:

• Heat-resistant glass fiber filter media

• Metal frames such as stainless steel or galvanized steel

• Aluminum or stainless steel separators

• High-temperature sealants and gaskets

• Designs optimized for thermal expansion and airflow stability

Material selection is critical to ensure safe and reliable operation at elevated temperatures.

Integration in Filtration Systems

High-temperature HEPA filters are typically installed:

• Downstream of heating or sterilization equipment

• As final filtration stages in high-temperature air streams

• In systems with controlled airflow and thermal management

Proper system design is essential to ensure even airflow distribution and avoid localized overheating.

Selection Considerations

When selecting high-temperature HEPA filters, key factors include:

• Maximum operating temperature and exposure duration

• Required filtration efficiency and applicable standards

• Airflow rate and allowable pressure drop

• Installation orientation and housing design

• Maintenance access and replacement intervals

Correct selection ensures both filtration performance and long-term system reliability.

Manufacturing and Quality Control

Clean-Link manufactures high-temperature HEPA filters with controlled material selection, precise assembly, and consistent quality standards. Each filter is designed to meet the demands of high-temperature industrial and critical environment applications.
