Attenuator MSA

FOR INCREASED INSERTION LOSS AND BROADBAND ATTENUATION EVEN IN THE LOW FREQUENCY RANGE
Splitter sound attenuators with integral splitters with resonating panels, suitable for air conditioning systems

Attenuation effect due to resonance and absorption
Energy efficient due to aerodynamically profiled frame (radius > 15 mm)
Acoustic data measured to ISO 7235
Absorption material is biosoluble and hence hygienically safe
Absorption material faced with glass fibre fabric as a protection against erosion due to airflow velocities up to 20 m/s
Absorption material non-combustible, to EN 13501, fire rating class A1
Intermediate sizes in increments of 1 mm
For use in zones 1 and 2 as well as in zones 21 and 22 according to EU Directive 94/9/EC (ATEX)
Operating temperature up to 100 °C


Optional equipment and accessories

Additional perforated sheet metal to protect the absorption material
Stainless steel, aluminium and PUR-coated constructions upon request
