MAJR’s Slim Line air ventilation panels offer a slim profile that is ideal for accommodating critical space limitations at air intake and exhaust aperture locations. The frame features an installed wire mesh gasket for EMI shielding at the mounting interface. MAJR offers a variety of standard Slim Line panel product sizes to choose from as well as a custom designed option for more unique requirements.
