99.999% H13/H14 Galvanized Steel Frame Standard Air Flow Filter for Dust Collector
(High-efficiency galvanized steel-framed H13/H14-grade air filter for dust collectors, with 99.999% filtration efficiency)
Product Overview
Core Functions:
This filter is specifically designed for industrial dust collection systems, utilizing H13/H14-grade HEPA filter media (compliant with European standard EN1822). It captures particles ≥0.1–0.3μm with 99.999% efficiency, suitable for ultra-clean environments or high-precision dust control applications (e.g., pharmaceuticals, semiconductors, food processing).
Structural Features:
Galvanized Steel Frame: Rust-resistant and corrosion-proof, adaptable to humid or dusty industrial environments.
Sealing Design: Uses polyurethane sealant or liquid-trough sealing to ensure no bypass leakage.
Modular/Integrated Options: Supports customized sizing to fit various dust collector models.
Technical Parameter Comparison
| Parameter | H13 Grade | H14 Grade | Notes |
|---|---|---|---|
| Filtration Efficiency (MPPS) | ≥99.975% | ≥99.995% | H14 is more suitable for stringent cleanliness requirements. |
| Initial Pressure Drop | ≤220 Pa | ≤250 Pa | Depends on airflow velocity and filter media thickness. |
| Dust Holding Capacity | Moderate (requires regular replacement) | Low (due to high precision) | H14 requires more frequent maintenance. |
| Application Scenarios | General cleanrooms, industrial dust collection | Semiconductors, pharmaceuticals, biolabs |
Core Advantages Analysis
Ultra-High Efficiency Filtration:
H13/H14-grade media intercepts PM0.3 particles (e.g., virus carriers, nanoscale dust), meeting ISO 14644-1 Class 5–7 cleanliness standards.
Durability of Galvanized Steel Frame:
More impact-resistant and heat-tolerant (short-term tolerance up to ≤80°C) than plastic or wooden frames, extending service life.
Standardized Design:
Compatible with mainstream dust collector brands (e.g., Donaldson, Camfil), reducing replacement costs.
Recommended Application Scenarios
Pharmaceutical Industry:
Sterile workshops, API production-requires H14 filters to prevent cross-contamination.
Semiconductor Manufacturing:
Reduces wafer defect rates in photolithography and etching processes with H13/H14 filters.
Food Processing:
Collects dust from powdered milk, sugar, etc., avoiding microbial or foreign matter contamination.
Hazardous Waste Treatment:
Filters toxic particulates from nuclear power plant or chemical plant exhaust.
Selection Recommendations
Based on Emission Standards:
Recommend H13 for PM2.5 ≤10μg/m³.
Choose H14 for PM0.3 ≤1μg/m³ (e.g., semiconductor cleanrooms).
Consider Operating Costs:
H14 offers higher precision but higher pressure drop and energy consumption; balance initial investment with long-term electricity costs.
Customization Needs:
Offers non-standard sizing, explosion-proof, and high-temperature-resistant (e.g., PTFE media) customization services.
Maintenance & Precautions
Regular Inspection:
Monitor filter clogging using a differential pressure gauge (recommended replacement pressure: 2× initial pressure drop).
Safe Replacement:
Wear protective gear during replacement to avoid secondary contamination from damaged media.
Waste Disposal:
Dispose of spent filters containing HEPA media as hazardous waste; avoid incineration (may release toxic gases).
Summary
H13 Grade: Cost-effective, suitable for most industrial dust collection scenarios.
H14 Grade: Preferred for ultra-clean requirements but at higher cost.
Galvanized Steel Frame: Significantly enhances durability, especially in humid or dusty environments.
