Product Description: Heavy-Duty H13/H14 Stainless Steel HEPA Filter for Tough Environments
Core Performance and Advantages
Medical-Grade High-Efficiency Filtration
H13 Grade: Filtration efficiency ≥99.95% for 0.3μm particles, balancing airflow and resistance for standard high-cleanliness applications.
H14 Grade: Efficiency elevated to ≥99.995%, capable of intercepting ultrafine particles (e.g., viral carriers, nanoscale dust), suitable for extreme environments like ISO Class 5 cleanrooms and biosafety laboratories.
Certification Standards: Complies with EN 1822 and ISO 29463 medical-grade HEPA standards, ensuring air cleanliness meets medical-grade requirements.
High-Temperature and Corrosion-Resistant Design
Frame Material: SUS304 stainless steel, resistant to high temperatures (up to 250°C) and corrosion, ideal for chemical, steel, and power industries operating in high-humidity or corrosive environments.
Filter Media: Glass fiber filter paper with excellent high-temperature resistance, maintaining structural integrity and stable filtration efficiency over prolonged use.
Long Lifespan and Low Maintenance Costs
Service Life: Typically 12–18 months, depending on operating conditions (e.g., dust concentration, humidity).
Maintenance: Supports pulse-jet cleaning to extend filter lifespan; regular differential pressure monitoring, with replacement required when exceeding 50% of the initial value.
Cost Efficiency: Washable and reusable H13/H14 filter media reduce long-term costs compared to frequently replaced traditional filters.
Low Resistance and Energy-Efficient Design
Initial Pressure Drop: H13 ≤220Pa, H14 ≤350Pa (@0.45m/s airflow velocity), minimizing energy consumption by fans.
Structural Optimization: Modular design accommodates varying airflow demands, reducing system pressure drop and enhancing overall energy efficiency.

Extreme Environment Adaptability
Blast furnace fans in steel plants, power boiler intake systems, and chemical reactor exhaust treatment.
Spray painting booths and dust recovery systems to prevent accumulation of flammable/explosive dust.
Selection and Compatibility Recommendations
Size Selection Based on Airflow
Example: For 1000m³/h airflow, select 610×610×150mm model; for 1500m³/h, choose 915×610×150mm.
Grade Selection Based on Cleanliness Requirements
Standard industrial settings: Opt for H13 grade to balance cost and efficiency.
High-risk environments (medical, semiconductors): Choose H14 grade to ensure zero leakage of ultrafine particles.
Environmental Adaptability Verification
High-temperature environments (>135°C): Confirm filter media temperature resistance.
Corrosive gas environments: Select galvanized or specially coated frames.
Maintenance and Replacement Guidelines
Regular Monitoring
Monitor differential pressure every 500 hours; clean or replace when exceeding 50% of the initial value.
Cleaning Methods
Pulse-Jet Cleaning: Reverse blow with 0.3MPa compressed air to restore dust-holding capacity.
Water Washing: Soak in neutral detergent and air-dry (applicable to washable models only).
Replacement Cycle
Standard environments: Replace every 3000 hours.
High-dust environments: Shorten to 2000 hours or adjust based on pressure drop trends.
