Why Choose Consion High Temp HEPA Filters?
1. Zero Volatile Organic Outgassing under High Temperatures
Utilizes specialized inorganic high-temperature sealants that will not crack, shrink, or release volatile gases during thermal cycling, preserving cleanroom air purity in critical manufacturing zones.
2. High Structural Rigidity & Uniform Airflow Channeling
Features precision-folded aluminum separators and stainless steel framing, maintaining media structural integrity and preventing airflow resistance spikes caused by thermal expansion.
3. Factory Direct Customization & Strict Quality Assurance
Every high-temperature HEPA filter undergoes strict factory DOP leak detection testing. We offer fully customizable dimensions, frame gauges, and thermal ratings to match original equipment OEM specs.
High temperature resistant high efficiency air filter is specially designed for special high temperature clean environment, and is mainly used in the following three fields:
High temperature clean room system
As the end filter of high temperature production process clean room such as electronic glass and special materials, it can withstand 250-350℃ high temperature environment for a long time, ensuring that the cleanliness of high temperature air supply reaches ISO 5 standard.
High temperature purification equipment
It is used in high temperature purification devices such as high temperature ovens, sintering equipment, special FFU, etc. It adopts stainless steel frame and special high temperature resistant sealing material, and still maintains H13-H14 level filtration efficiency at high temperature.
Special industrial scenarios
High temperature resistant high efficiency air filters are widely used in high temperature production processes such as lithium battery sintering, optoelectronic material preparation, and aerospace. They use metal partitions and ceramic fiber filter materials, and are sealed with special high temperature glue. They do not deform or degrade under continuous high temperature conditions, and are a reliable guarantee for high temperature clean environments. The product has passed the 300℃/1000h durability test and meets the most stringent industrial high temperature filtration requirements.
Filter element characteristics
The High temperature resistant high efficiency air filter uses special ceramic fiber filter material, which has excellent filtering performance: the filtration efficiency of 0.3μm particles is ≥99.97% (H13 grade), the initial resistance is ≤250Pa, and the dust holding capacity is more than 500g/m². The product adopts a high temperature resistant stainless steel frame, which can work stably in a high temperature environment of 250-350℃ for a long time, and is an ideal choice for high temperature clean processes.

Industrial & Cleanroom Applications
- Pharmaceutical Sterilization Tunnels: Ampoule filling lines, hot air sterilizers, and depyrogenation tunnels all use terminal air filtration.
Automotive and Industrial Spray Booths: Clean drying procedures, automobile curing lines, and high-temperature paint baking ovens.
Manufacturing of semiconductors and optical glass: dust-free, high-temperature baking and thermal processing apparatus.
High-temperature exhaust gas purification and high-heat process air supply are used in chemical and food processing.
Frequently Asked Questions (FAQ)
Q1: How do I choose between a 250°C and a 350°C high-temperature HEPA filter?
250°C models typically use red silicone sealant, making them cost-effective for standard high-temp drying ovens. 350°C models utilize specialized ceramic adhesive or inorganic sealants designed for pharmaceutical sterilization tunnels where higher heat resistance and zero outgassing are mandatory.
Q2: Can Consion Filter manufacture non-standard sizes for OEM replacement?
Yes. We manufacture custom-dimension high-temperature HEPA filters according to your exact CAD drawings, frame thickness, and operational requirements.
