HZL Series Sub High Efficiency Pleated Air Filter For Cleanroom HVAC System
What Is A HZL Series Sub High Efficiency Pleated Air Filter?
A: The HZL Series Sub High Efficiency Air Filter is a medium-to-high efficiency pleated air filter applied in HVAC air handling systems and cleanroom ventilation systems.It uses ultra-fine filter materials and a compact structure to balance high dust capacity, low resistance, and flexible efficiency (medium/sub-high/high), tailored for HVAC pre-filtration in commercial and industrial buildings.

Performance and Characteristics
Core Advantages
1. Frame Structure
Outer frame options: galvanized steel plate or plastic frame, good rigidity, deformation resistant, suitable for long-term fixed installation inside air cabinets.
2. Filter Media
Available filter materials: ultra-fine polypropylene filter paper, glass fiber filter paper; filtration grades cover high efficiency, sub-high efficiency and medium efficiency to meet diverse purification demands.
3. High Airflow & Cost Advantage
Under equal air volume demand, fewer HZL filters can replace multiple ordinary high-efficiency filters, saving installation space, cutting installation time and overall procurement cost.
4. Large Dust Holding Capacity (No Partition Design)
Adopts ultra-fine, fire-resistant, moisture-proof glass fiber matched with thermoplastic barrier strips; unified fold spacing ensures smooth airflow with low resistance. The full-depth filter material is fully utilized, realizing larger dust holding capacity and longer service cycle.
5. Stable Running Performance
Even fold spacing avoids local airflow bias and early local clogging, maintaining stable resistance and filtration efficiency in long-term operation.
Function & Application
Cleanroom Projects: Intermediate filtration for pharmaceutical, electronic, food processing clean workshops, pre-protection for H13/H14 HEPA filters
Commercial HVAC System: Secondary filtration for office buildings, shopping malls, hospitals, hotels
Industrial Ventilation: Workshop ventilation purification, paint room air supply pretreatment
Fresh Air Units: Terminal secondary purification of household and commercial fresh air systems
