Acoustic transfer grill SK1

doorfor partition wallgalvanized steel

For air transfer between rooms Low pressure drop Effective sound attenuation Adjustable for different wall thicknesses Seven sizes 400x150 - 1000x150. Suitable for wall/door thicknesses of 95-145 mm. Made of hot-galvanized steel and front panels of aluminium. Sound attenuation material is mineral wool. Visible parts are painted in white RAL 9003. SK1 is used for air transfer between rooms when sound attenuation in the air flow opening is needed. SK1 is usually installed into the wall or above a door. SK1 is usually installed into the wall above a door. The low pressure drop of the device allows relatively large air transfer volumes between rooms. On the other hand, an excellent level of total sound attenuation of the wall is attained by the good silencing qualities of the device. View through the device is obstruc ted by the design. The depth of the casing is adjustable to the wall thickness. The air flow from one room to another is due to differences in pressure. Air flows through a rectangular slot on the front panel of SK1. The device functions as a silencer in an opening between rooms. The casing is made of hot-galvanized steel and front panels of aluminium. The sound attenuation material is mineral wool. The front panels are powder coated. Standard color is RAL 9003. Other colours on request. The device is installed into an opening in a wall or a door. The minimum dimensions of the opening are B x 150 mm (B = nominal width of the device). The thickness of the wall can be from 95 mm to 145 mm.
