Splitters and splitter attenuators are suitable for use in air conditioning and ventilation systems certified and compliant to VDI 6022 Part 1 and Part 3 as well as to DIN 1946 Part 2 and Part 4 and VDI 3803.

The turbulences of the sound attenuator inlet and outlet are reduced by the aerodynamically profiled frame of the splitters. The pressure drop is reduced up to 30 %.
It is thus possible to select smaller gaps and a shorter silencer.
As a result, a more compact design results in direct savings of the operating costs and/or in space saving. When using additional necessary aerodynamic profiles, acoustic and ineffective splitters lengths can be avoided.

Casing

• Folded casing of galvanised sheet steel stiffened by crimping; larger dimensions additionally with reinforcing strip.
• Connection frame air duct section (30 mm); alternatively, a frame perforated at the factory of galvanised angular steel 35 by 5 mm available.

Splitters

• Aerodynamically shaped frame of galvanised sheet steel, stiffened by crimping.
• Absorption material (highly bio-degradable, no health risk) with laminated non-woven glass fibre fabric to provide protection against abrasion at air velocities of up to 20 m/s; rot-proof and moisture-repellent impregnation, non-flammable according to DIN 4102 A2.
• External lambda panels and internal partitioning panels of galvanised sheet steel.
• Operating temperature up to 100 °C.
• Can be installed in any position up to a height of and including 1200 mm.
• Fulfills the hygiene requirements of VDI 6022, DIN 1946 part 2 and part 4 as well as of VDI 3803.
