Pre Filter

1. High Dust Capacity Design, Extending System Maintenance Cycles

SYNRUI pre-filters utilize a progressive fiber structure, where fibers progressively finer to intercept particles, increasing dust capacity per unit area by 15%–25% compared to traditional uniform cotton filters.

Why is it more durable?

Because the progressive structure allows particles to deposit layer by layer, preventing rapid surface loading and a sudden increase in resistance, thus extending replacement cycles and reducing customer operating costs.

2. Low Initial Resistance, High Airflow Structure, Reducing HVAC Energy Consumption

The initial resistance of the pre-filter is controlled at 30–55 Pa (depending on the model), approximately 10–15% lower than the market average.

Reason: SYNRUI uses synthetic fiber materials with controllable fiber diameter, achieving higher ventilation efficiency and better matching with AHU fans, thereby reducing motor power loss.

For energy-cost-sensitive factories or large commercial buildings, the low-resistance pre-filter can significantly reduce electricity costs over the system's lifespan.

3. 100% Factory Inspection to Ensure Batch Stability and Quality Consistency

Each product undergoes the following inspection processes:

Appearance and Structural Stability Inspection

Airflow Resistance Test

Efficiency Inspection (Compliant with G4 or EN779:2012 Standards)

Particle Penetration Inspection

How can batch consistency be achieved?

Relying on a Class 100,000 cleanroom and automated production equipment, SYNRUI's fiber web laying, pleating, and metal frame assembly all employ fixed procedures and parameterized management to ensure consistent performance and no drift between batches.
