Product Specifications

Technical details and manufacturing context for HEPA Filter Bank

Definition
A HEPA filter bank is a critical component of an Air Handling Unit (AHU) that consists of multiple HEPA (High-Efficiency Particulate Air) filters arranged in a bank configuration. Its primary role is to provide the final stage of air filtration, capturing at least 99.97% of particles 0.3 microns in diameter or larger from the airstream before conditioned air is supplied to cleanrooms, laboratories, hospitals, pharmaceutical facilities, or other controlled environments requiring ultra-clean air.
Working Principle
Air is forced through the dense, pleated media of the HEPA filters. Particles are captured through a combination of interception, impaction, and diffusion mechanisms. The bank configuration allows for a larger total filtration area, reducing air resistance and extending filter life compared to a single filter, while maintaining the required high-efficiency particulate removal.
Common Materials
Glass fiber media, Aluminum separator, Polyurethane sealant, Galvanized steel or aluminum frame
Technical Parameters
  • Overall dimensions (Height x Width x Depth) of the filter bank assembly. (mm) Standard Spec
Components / BOM
  • HEPA Filter Cell Part
    Individual filter unit containing the pleated media; the basic building block of the bank.
  • Filter Frame
    Holds multiple filter cells in a rigid, sealed assembly and provides mounting interface to the AHU.
  • Gasket/Seal Part
    Ensures an airtight seal between the filter bank frame and the AHU housing to prevent bypass.
  • HEPA Filter Module
    Individual filter unit containing pleated media for particle capture
    Material: Glass fiber media with aluminum separators

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Filter Media Degradation
Cause: Excessive particulate loading beyond design capacity, leading to media clogging, tearing, or chemical degradation from corrosive aerosols.
Seal Failure
Cause: Gasket or seal material degradation due to aging, improper installation, or exposure to incompatible chemicals, resulting in bypass leakage around the filter.
Maintenance Indicators
  • Significant increase in system differential pressure (ΔP) beyond the manufacturer's recommended change-out threshold, indicating severe clogging.
  • Visible particulate emissions downstream of the filter bank or audible air whistling/leakage sounds at the filter housing seals.
Engineering Tips
  • Implement a predictive maintenance program using continuous differential pressure monitoring with set alarms to schedule filter changes before catastrophic clogging or bypass occurs.
  • Ensure proper installation and regular inspection of gaskets/seals; use compatible materials for the operating environment and follow a torque sequence during housing assembly to prevent uneven compression and leaks.

Compliance & Manufacturing Standards

Reference Standards
ISO 29463: High-efficiency filters and filter media for removing particles in air ANSI/ASHRAE 52.2: Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size EN 1822: High efficiency air filters (EPA, HEPA and ULPA)
Manufacturing Precision
