Materials
Outer casings fabricated from galvanised steel sheet with a riveted construction. Splitters made from perforated pre-galvanised steel sheet. Acoustic media is a non-toxic inorganic infill packed under 10% compression to eliminate voids. Melinex wrap on the acoustic media is available for clean room and grease laden atmospheres. Chlorinated rubber painted internal surfaces are available for use in corrosive environments. Polyester powder coat paint finish available in many RAL colours.
