1. Brief Introduction to HEPA Box and Its Application in the Food Industry

1.1 Definition of HEPA Box

A HEPA Box is a clean air distribution device equipped with a HEPA (High Efficiency Particulate Air) filter, installed at the final air supply points in a cleanroom system. This device removes fine dust, microorganisms, and contaminants with a particle size of 0.3 microns or larger, with a filtration efficiency of ≥ 99.97% (H13) or ≥ 99.995% (H14).

In food factories, HEPA Boxes are typically installed on ceilings or walls in production, packaging, or processing areas to ensure the supplied air is always clean and meets the highest hygiene standards.

1.2 Role of HEPA Box in Ensuring Food Safety and Hygiene

  • Preventing airborne contamination: Eliminates dust particles, mold, and bacteria from the supplied air in production areas.
  • Maintaining a stable cleanliness level: Keeps dust and microbial concentration within permissible limits required for food processing areas.
  • Protecting product quality: Reduces cross-contamination risks, extends product shelf life.
  • Optimizing HVAC performance: Designed to distribute air evenly and minimize turbulence that can cause dust accumulation.

1.3 Relevant Standards

When using HEPA Boxes in food factories, the following standards should be met:

  • ISO 14644 - International standard for classification and control of cleanroom cleanliness levels.
  • HACCP (Hazard Analysis and Critical Control Points): A food safety management system requiring air quality control in production areas.
  • Food GMP (Good Manufacturing Practice): Regulations on good manufacturing practices, including air filtration systems, clean air supply, and contamination control.

2. Factors Affecting the Price of HEPA Box in Food Factories

The price of a HEPA Box depends not only on the brand or supplier but also on various technical and usage requirements. Key factors include:

2.1 Size and Airflow (CFM)

  • Size: Larger HEPA Boxes require more materials and production time, leading to higher costs.
  • Airflow (CFM): Higher airflow requires larger fans and filters to ensure proper air velocity.
  • Food application: Main processing areas often require higher airflow to maintain a stable cleanliness level.

2.2 HEPA Filter Grade (H13, H14) and Efficiency

  • H13: Efficiency ≥ 99.97% for particles ≥ 0.3 microns.
  • H14: Efficiency ≥ 99.995% for particles ≥ 0.3 microns, suitable for areas with strict hygiene requirements.
  • Note: Higher filter grades increase both filter and HEPA Box prices.

2.3 Construction Materials

  • Powder-coated steel: Cost-effective, basic rust protection, suitable for dry environments.
  • Stainless Steel 304: Good corrosion resistance, easy to clean, commonly used in the food industry.
  • Stainless Steel 316L: Superior corrosion resistance, withstands chemicals and humid environments, highest cost.

2.4 Integrated Fan Type (if any) and Power

  • Non-fan HEPA Box: Lower cost, usually connected to a central air supply system.
  • HEPA Box with fan (integrated FFU): Provides independent clean air supply, not entirely dependent on HVAC systems, but more expensive due to added motor, speed controller, and soundproofing.

2.5 Additional Options

  • Differential pressure gauge: Monitors filter condition and replacement time.
  • UV lamp: Disinfects air, reducing microbial contamination.
  • Noise reducer: Lowers noise levels during air supply, important for long-term working environments.

4. Criteria for Selecting a Suitable HEPA Box for Food Factories

4.1 Cleanliness Level Required for Each Production Area

  • Direct processing/packaging areas: Usually require H14 filter grade to remove maximum fine dust and microbes.
  • Pre-processing or storage areas: May use H13 filters if hygiene requirements are less strict.
  • According to ISO 14644 & HACCP: Each cleanliness class specifies maximum particle counts, guiding HEPA Box selection.

4.2 Initial Investment and Maintenance Costs

  • Initial investment: Balance technical requirements with budget. SS316L or fan-integrated models cost more but last longer.
  • Maintenance costs: Includes periodic filter replacement (12-18 months), pressure gauge checks, surface cleaning. Easier maintenance reduces long-term costs.

4.3 Corrosion and Moisture Resistance Requirements

  • Humid or wet areas: Use SS304 or SS316L to avoid rust.
  • Areas exposed to harsh cleaning chemicals: SS316L is optimal.
  • Dry environments with limited budget: Powder-coated steel can be used to save costs.

4.4 Ease of Filter Replacement

  • Easy frame removal design: Shortens maintenance time, reduces contamination risk.
  • Airtight sealing gaskets: Prevent leakage of dirty air during replacement.
  • Integrated differential pressure gauge: Ensures timely filter replacement.
