Product Description

Performance Features

Low resistance, high air volume, long service life, large filtration area, and high dust-holding capacity.

Sturdy structure, capable of normal operation under ultra-high air volume conditions.

Application Fields

Primary filtration for industrial and civil ventilation systems; pre-filtration for centralized HVAC systems in cleanrooms.

Design Features

Box filters use synthetic fiber and non-woven filter materials to create replaceable filter cartridges, reducing operating costs.
High-strength outer frame with added support design enhances the durability and strength of the filter.
Available in both "flanged" and "non-flanged" configurations.
A sealing gasket can be optionally installed between the box-style folded filter and the fixed frame to prevent air leakage.
Filtration efficiency grades: G1, G2, G3, G4 (EN779).

FAQ

Q1: What applications is this primary filter suitable for?

A: Ideal for commercial buildings, factory workshops, cleanroom pre-filtration, and HVAC systems. It effectively captures large particles like dust, hair, and fibers, extending the lifespan of medium/high-efficiency filters.

Q2: How often should the filter be replaced?

A: Replacement intervals depend on the operating environment. Generally, inspect every 3-6 months. Replace when resistance reaches the final resistance (e.g., ≥250Pa) or visible dust accumulation occurs.

Q3: Can it be cleaned and reused?

A: Not recommended. Washing synthetic fiber media reduces filtration efficiency. We advise replacing the filter cartridge directly for optimal performance.

Why Choose Us?

Premium Materials: High-strength frame + synthetic fiber media ensure low resistance, high dust capacity, and extended service life.
Flexible Compatibility: Multiple sizes (customizable) and flanged/flangeless installation options to fit various ductwork requirements.
High-Efficiency Filtration: Complies with EN779 standard (G1-G4 available), effectively protecting downstream high-grade filters.
Cost-Effective & Durable: Replaceable cartridge design reduces long-term maintenance costs, offering better value than disposable filters.
