Industrial Ventilation & Indoor Air Quality (IAQ) Standards

Indoor Air Quality (IAQ) directly dictates worker health, regulatory safety compliance, and delicate machinery precision in modern industrial and commercial environments.

1. Multi-Stage Air Filtration

Modern AHUs engineered by Hegel Engineering incorporate multi-tier filter banks conforming to EN 779 / ISO 16890 standards: coarse G4 pre-filters, high-efficiency ePM1 F7/F9 pocket filters, and terminal H13/H14 HEPA units for cleanroom manufacturing.

2. Energy Recovery Ventilators (ERV / HRV)

Exhaust air thermal energy is recaptured via rotary thermal wheels or plate heat exchangers, conditioning up to 80% of incoming fresh ventilation air without compressor intervention.
