MagnaVent is an energy saving insulation cover that seals and insulates a whole house fan grill. The cover fits over your whole house fan grill using an advanced magnetic seal. The insulated cover is easily removed from the fan grill during seasonal use and snaps back into place magnetically to cover the grill during the winter.
The magnetic sealing system provides a method to attach the cover and provide a clean smooth seal to help prevent drafts. When the cover is removed it leaves a smooth white strip of a magnetic seal which blends in with the grill facing and unlike hook and loop fasteners, the magnetic seal can be wiped clean with a damp cloth to remove dust that collects during operation. When the cover is in place, it creates an attractive look that has a white textured surface.
Ideal for workers with smaller ear canals, Max Lite’s low-pressure polyurethane foam expands gently inside the ear canal for comfortable long-term wear, while its contoured T-shape delivers ease of handling.Features
