Product Key Features
- Energy Efficient Profile: Engineered for low initial resistance (typically ≤120-200Pa), optimizing total system efficiency.
- High Dust Holding Capacity: The deep pleat structure provides a massive surface area to capture up to 1120g of dust, extending the service life between replacements.
- Rigid Construction: Built with a reinforced aluminum alloy frame or galvanized steel to withstand high-velocity airflow.

Material & Craftsmanship
- Filter Media: Premium synthetic fiber or fiber glass paper media with gradient density for layered filtration.
- Frame Build: Durable Aluminum alloy (Anodized) for corrosion resistance and lightweight handling.
- Sealant: Secured with professional polyurethane sealant to ensure zero air bypass.
Applications
Commercial Ventilation Systems: Ideal for applied in air conditioning systems of airports, premium office towers, and large-scale shopping malls where high air quality and energy efficiency are paramount.
Industrial Air Intake: Acts as a reliable secondary filtration stage for centralized AHU units and general factory air purification, protecting sensitive downstream components.
Public Infrastructure: Optimized for high-traffic environments requiring general air purification to handle a high air flow without excessive energy draw.
Pre-filtration for HEPA Filters: Specifically engineered to serve as an efficient pre-filter, capturing larger particles to extend the service life of terminal HEPA filters in controlled environments.
Data Centers: Provides stable filtration with low initial resistance, ensuring critical server cooling systems remain dust-free while minimizing cooling-related power costs.

This precision engineering optimizes total system efficiency and significantly reduces fan motor power consumption.

Frequently Asked Questions
Q1: How does the “Low Resistance” design translate to actual energy savings?
Our Pleated Medium Filter is engineered for an initial resistance of typically ≤120-200Pa. By maintaining a minimal pressure drop, your HVAC fan motors don’t have to work as hard to push air through, leading to a significant reduction in total system energy consumption.
Q2: Will the filter media remain stable under high-velocity airflow?
Yes. The filter is built with a reinforced aluminum alloy frame or galvanized steel and secured with professional polyurethane sealant. This rigid construction is specifically designed to withstand high-velocity airflow without media bypass or deformation.
Q3: What is the benefit of the “Deep Pleat” structure?
The deep pleat design provides a massive surface area that can capture up to 1120g of dust. This high dust holding capacity significantly extends the interval between filter changes, offering an industry-leading long service life.
Q4: Can this filter be used in humid environments?
Absolutely. We use premium synthetic fiber or gradient density fiber glass paper media and durable anodized aluminum frames, which provide excellent resistance to moisture and corrosion.
Q5: Is this filter suitable for protecting terminal HEPA filters?
Yes, it is a perfect choice for secondary filtration. By efficiently capturing sub-micron and larger particles, it acts as a high-performance shield that extends the lifespan of expensive terminal HEPA filters in pharmaceutical or electronics sectors.
