Ventilation Equipment
Mechanical ventilation systems for dilution and pressure control. Heat-recovery ventilation (MVHR/HRV/ERV), single-flow ventilation, positive input ventilation (PIV), crawlspace ventilation fans, and balanced ventilation systems. Effective as complementary measures or standalone solutions at moderate radon levels (300–600 Bq/m³), with reduction factors of 2–4 depending on system type and building airtightness.
Application
Intervention Type
Mechanical ventilation systems reduce radon through dilution and pressure control. Effective as complementary measures or standalone solutions at moderate radon levels (300–600 Bq/m³).

Product Types
Heat Recovery Ventilation (HRV/ERV)
Balanced ventilation systems exchanging indoor air while recovering heat energy
- •Moderate reduction factor
- •More effective for basement ventilation
Positive Input Ventilation (PIV)
Pressurization systems reversing pressure gradient between indoor spaces and soil
- •BRE reduction factor 3-4 up to 700 Bq/m³
- •Depends on building airtightness
Single-Flow VMC
Mechanical exhaust ventilation systems
- •Can depressurize building if not balanced
- •Balanced or supply ventilation preferred
Crawlspace/Sub-floor Ventilation
Natural or mechanical ventilation of containment space beneath building
