The Lifebreath 99-187 kit provides a comprehensive solution for outdoor air management in larger ventilation systems, featuring two 7-inch diameter weather hoods along with a 12-inch sleeve and collar. This assembly is essential for protecting the intake and exhaust ports of high-capacity Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs).
This product is specifically tailored for HVAC professionals and homeowners working with larger residential or light commercial balanced ventilation systems. The weather hoods are critical for shielding against rain, snow, and debris, while the sleeve and collar ensure a secure, insulated, and airtight penetration through the building's exterior. The dual hood configuration is ideal for systems requiring distinct intake and exhaust pathways.
When considering this kit, verify that the 7-inch diameter is compatible with your HRV/ERV unit's duct connections, accommodating higher airflow requirements. The 12-inch sleeve offers versatility for various wall thicknesses, facilitating a professional and sealed installation. This Lifebreath accessory is a vital component for maximizing the efficiency and lifespan of your advanced ventilation system.
