Partitionless High Air Volume Filter For Hospital & Airport Ventilation Systems

A: The HZL Series Sub High Efficiency Air Filter is a high-performance pre-filtration solution for HVAC and ventilation systems, designed to balance high filtration efficiency, low resistance, and cost-effectiveness.

Frame & Media Options:

Outer frame: Galvanized steel plate or plastic for durability and corrosion resistance.

Filter media: Ultrafine polypropylene filter paper or glass fiber filter paper, supporting high, sub-high, and medium efficiency grades.

High Air Volume Design: Compared with standard high-efficiency filters, fewer units are required to achieve the same airflow, reducing installation space, time, and overall system costs.

Partitionless, High Dust Capacity Structure: Constructed from ultra-fine, moisture-proof, fire-resistant glass fiber with thermoplastic rubber barriers to maintain consistent pleat spacing. This ensures low airflow resistance, full utilization of filter media depth, and maximum dust-holding capacity.

Widely used in heating and ventilation air-conditioning systems for industrial and commercial buildings, including:

Office buildings, conference rooms, hospitals, shopping malls, gymnasiums, airports, and other large public facilities.

As pre-filtration for centralized ventilation and air conditioning systems in ordinary industrial plants or clean rooms.

OEM, OEM Production services. Independent R&D team, one-stop solution for cleanroom projects.
