High-efficiency pleated filter
The dense-pleated high-efficiency filter is a high-efficiency air filtration device designed with a Mini-pleat (no partitions dense pleats) structure. It uses ultra-fine glass fiber filter material and is separated by hot melt adhesive to form a stable and uniform V-shaped pleat structure, achieving a larger filtration area and higher filtration efficiency in a limited space.

The product is mainly used to filter tiny particles of 0.3μm and above in the air. It is widely used in pharmaceutical clean rooms, hospital operating rooms, electronic semiconductor workshops, biological laboratories and various high-level HVAC air purification systems. It is one of the most commonly used high-efficiency filtration solutions in modern clean engineering.

The ultra-fine glass fiber filter material is densely pleated and has an integrated sealing structure. It has high filtration accuracy and efficiently intercepts tiny particles. It is mostly used for terminal purification of clean environments.

Product features: stable performance, easy installation; large effective filtration area and long service life; produced in a Class 10,000 clean factory with no volatile dust; low energy consumption during production and use, complying with low-carbon environmental protection requirements.

Why choose dense pleated high-efficiency filter

Higher filtration efficiency

It can stably reach H13/H14 level and effectively intercept particles of 0.3μm and above.

Larger filtration area

The Mini-pleat structure provides a larger effective filtration area under the same size and improves dust holding capacity.

Lower operating resistance

Optimize the air flow channel design, significantly reduce system pressure loss and save fan energy consumption.

Lightweight structure

No traditional partition design, the overall weight is lighter and the installation is easier.

Suitable for energy-saving systems

Very suitable for modern VAV systems and energy-saving HVAC systems.

Stable and reliable

The hot melt adhesive separation structure ensures long-term operation without deformation or collapse.
