More About This Product

RackSeal rack air barrier is a solution that prevents hot exhaust air recirculating to the front of server racks between the mounting rails and the rack sides. An area which, until now, has been difficult to seal.

RackSEAL rack air barrier seals gaps between rack rails & side panels

RackSEAL air barrier has been developed to seal the gaps between rack rails and the side panels to prevent hot exhaust air migrating to the front of the rack. Whilst blanking panels seal unused rack space little attention has been given to the area between the rails and the side panels. Preventing hot exhaust air recirculating within and between IT equipment racks plays an important role in improving airflow management and reducing Data Centre cooling costs. With blanking panels being used to seal unused rack space, hot air has still been able to migrate to the front of the racks via the gaps between mounting angles and sides of racks, externally between racks and underneath racks that are on castors.  What was needed was an air barrier that would effectively seal these areas – RackSEAL rack air barrier.

RackSEAL rack air barrier is a compressed foam tape that expands to fill a range of gap sizes and works with 600mm or 800mm wide racks.  The RackSEAL air barrier is easy to install, as it is self adhesive and is simply stuck to the side of the rack, the base of the rack or to the mounting rails.  RackSEAL air barrier still permits cables to be passed between the side of the rack and the rails, and simply moulds itself around them to ensure gaps are sealed.
