Spacepak bm-6819 Air Shut-off Roof Cap

Product Description

The SPACEPAK bm-6819 is an air shut-off roof cap designed to terminate roof exhaust vent pipes and ducts. It installs at the end of the exhaust run and serves two functions: blocking rain, debris, and pests from entering the duct system, and directing exhaust gases away from the mounting surface to prevent backflow into the system. Licensed HVAC technicians and sheet metal contractors install this component as part of residential or light-commercial ventilation systems. Its weather hood construction makes it suited for rooftop termination points where exposure to the elements demands a durable, weather-resistant fitting.

The bm-6819 is used in rooftop exhaust applications where duct terminations require protection from wind-driven rain, debris intrusion, and exhaust backflow. It is compatible with the Spacepak SZ and SP series systems and is appropriate for installations where the exhaust duct exits through the roof plane. This component is manufactured in the USA and is intended for use with Spacepak brand ventilation equipment.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the ventilation system completely before beginning work on the duct termination. Secure the cap according to local building codes and manufacturer roofing penetration requirements. Ensure the hood is oriented correctly to direct exhaust away from the roof surface and any adjacent air intakes.
