Sub High Efficiency Air Filter (HZL Series) – High Air Volume for Industrial Ventilation Filtration
What Is A Sub High Efficiency Air Filter?
A: The HZL Series Sub High Efficiency Air Filter is a multi-efficiency air purification device with a partitionless design. It uses ultra-fine filter materials and optimized fold spacing to balance large air volume, high dust capacity, and low resistance, serving as a key component in HVAC pre-filtration systems.

Performance and Characteristics
Core Advantages
Diverse Materials & Efficiency Options:
Outer frame: Galvanized steel plate/plastic (adaptable to different installation environments).
Filter material: Ultra-fine polypropylene filter paper/glass fiber filter paper (supports high, sub-high, and medium filtration efficiency).
High Air Volume & Cost Efficiency: Compared with 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 the utilization of filter material depth, enabling larger dust holding capacity while maintaining small airflow resistance; the filter material is ultra-fine, moisture-proof, and fire-resistant.
Function & Application
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.
