Food & Beverage Processing: Delivering robust, high-efficiency filtration to maintain sterile conditions in food processing air purifier setups for sensitive processing, filling, and packaging lines, effectively preventing cross-contamination.
Laboratory & Research Facilities: Ensuring precision dust control and long-term filtration stability for controlled research environments, bio-safety cabinets, and high-grade hospital ventilation filter infrastructure.
Data Centers & Server Rooms: Specialized high-capacity filtration for electronics cleanroom filtration to protect sensitive electronic components from airborne contaminants and micro-dust buildup, ensuring maximum system uptime.
| Key Evaluation Criteria | Our Factory-Direct Filters | Standard Market Competitors |
|---|---|---|
| Compliance & Certification | Strictly compliant with ISO 16890/EN 779; each batch includes a traceable performance test report. | Often lack verified test data; efficiency claims are frequently overstated or inconsistent. |
| Filtration Stability | Advanced hot-melt pleating ensures uniform spacing, preventing media collapse during high airflow. | Traditional aluminum/paper separators easily warp or tear, causing airflow short-circuits. |
| Supply Chain Resilience | Direct factory production offers agile manufacturing, ensuring short lead times for large-scale B2B orders. | High reliance on intermediaries results in delayed shipping and limited production capacity. |
| Build & Structural Integrity | Reinforced high-strength extruded aluminum frames provide long-term vibration resistance and zero leakage. | Use of fragile cardboard or thin sheet metal often leads to frame deformation and air bypass. |
| Total Energy Efficiency | Optimized gradient-density media ensures low initial resistance (≤120-200 Pa), slashing HVAC energy consumption. | High-resistance designs force HVAC fans to run at higher power, significantly increasing operational costs. |
| Engineering Customization | Tailor-made solutions: flexible dimensions, frame types, and media grades to fit non-standard AHU specs. | Restricted to rigid, generic off-the-shelf sizes with zero capability for project-specific modification. |
| Dimension (mm) | Rated Air Flow (m³/h) | Initial Resistance (Pa) | Efficiency Class | Dust Holding Capacity (g) |
|---|---|---|---|---|
| 610 × 610 × 50 | 700 ~ 1500 | ≤ 120–200 | F6 ~ F9 | 450g |
| 915 × 610 × 50 | 1000 ~ 2200 | ≤ 120–200 | F6 ~ F9 | 680g |
| 1220 × 610 × 50 | 1400 ~ 3000 | ≤ 120–200 | F6 ~ F9 | 900g |
| 610 × 610 × 69 | 1000 ~ 2000 | ≤ 120–200 | F6 ~ F9 | 560g |
| 915 × 610 × 69 | 1500 ~ 3000 | ≤ 120–200 | F6 ~ F9 | 840g |
| 1220 × 610 × 69 | 2000 ~ 4000 | ≤ 120–200 | F6 ~ F9 | 1120g |
