High-Temp HEPA Air Filter– High Dust Capacity for High-Temp Air Purification Systems

A: Sub High Efficiency Air Filter is a partitionless air purification device with multi-efficiency options (medium/sub-high/high). It uses ultra-fine filter materials and optimized fold spacing to balance large air volume, high dust capacity, and low resistance, tailored for HVAC pre-filtration in commercial/industrial buildings.

Diverse Material & Efficiency Options: Outer frame (galvanized steel plate/plastic) and filter materials (ultra-fine polypropylene/glass fiber paper) support medium, sub-high, and high filtration efficiency.

High Air Volume & Cost-Saving: Compared to ordinary high-efficiency filters, fewer units are needed for the same air volume-reducing costs, installation space, and setup time.

High Dust Capacity & Low Resistance: Partitionless design with thermoplastic rubber separators ensures uniform fold spacing. This maximizes filter material utilization, enabling large dust holding capacity while maintaining small airflow resistance.

Durable & Stable: Made of ultra-fine, moisture-proof, fire-resistant glass fiber, ensuring reliable performance in diverse environments.

It is widely used in:

HVAC systems for commercial/industrial heating and ventilation: Large civil buildings (office buildings, hospitals, airports, shopping malls, etc.).

Pre-filtration: Ventilation/air conditioning systems in ordinary industrial plants or clean centralized ventilation systems.
