Description
MKW / MWS
MLK / MLS
Silencing baffles type MWK
Baffles with frame profile in nozzle design for substantial reduction of the pressure loss. The mineral fibre boards are covered
with unmetabolisable glass silk, i.e., no bacteria can deposit on
the glass silk, and are not flammable according to DIN 4102.
Baffles measured to ISO/DIS 7235 and to DIN 45646. Manufactured to the hygienic standards of VDI 6022.
For use at a main interfering frequency between 500 Hz and
8000 Hz. The baffle plate thickness is 0.5 mm.
Silencing baffles type MLK
Both sides covered with perforated sheet steel t = 0.5 mm.
For use at a main interfering frequency between 500 Hz and
8000 Hz. The baffle plate thickness is 0.5 mm.
Baffle silencer type MWS
Baffle silencer with integrated baffles type MWK.
Duct housing made of 1.0 mm thick galvanised sheet steel with
airtight saddle joint. Internal pressure up to 1000 Pa max.
Metu profile M 30 on both sides. Manufactured to the hygienic
standards of VDI 6022.
For use at a main interfering frequency of 500 Hz to 8000 Hz.
Baffle silencer type MLS
Baffle silencer with integrated baffles type MLK.

Baffles with frame profile in nozzle design reduce the pressure
loss by up to 55% compared with conventional baffles. This
gives high energy-saving in the operation of the system!
The baffles and baffle silencers are delivered in a hygienic design to VDI 6022. The objective of the VDI 6022 "Hygienic planning, design, operation and maintenance of air-conditioning
installations" is a hygienically impeccable interior air quality, i.e.,
avoidance of microbial contamination of the inhaled air. Accordingly, installation components must not emit any substances, fibres or odours hazardous to health, and must not promote
the growth of microorganisms. The hygienic qualification tests
and the data verified within the scope of the RAL quality inspection are basic quality characteristics of our sound isolation components.
The mineral wool silencers type MWS / MBS / MLS / MBLS have
been tested successfully by TÜV-Süd in accordance with the following rules:
- VDI 6022, Sheet 1: Hygienic requirements of ventilation
and air-conditioning systems
- VDI 6022, Sheet 2: Hygienic requirements of ventilation
and air-conditioning systems - Measurement methods and
investigations during hygienic controls and hygienic inspections
- DIN 1946, Sheet 2: Air-conditioning technology - Health requirements
For maintenance, service, retrofitting, etc., inspection openings
in sufficient number and size must be provided on-site.
Installation of baffles or silencers:
When baffles are delivered separately, the determined performance data are only reached if the manufacturer's installation instructions and the recognised technical rules are observed. The
mineral wool silencer should be laid out inside the ventilation installation in front of the air filter, so that possible fibre separations stay in the filter.
Attention:
The baffle height <200mm cannot be delivered in the nozzle design.
Design only possible in folded form!
The baffle silencers from SCHAKO have been awarded the RAL
quality mark 595 by the RAL Quality Association. The SCHAKO
KG is a member of the RAL Quality Association for Silencers

Division of baffle silencer type MWS/MBS/MLS/MBLS
If the silencer dimensions are in the limiting area with respect to
all three dimensions (L/H/B), we reserve the right to change the
silencer division. This will limit the weights and dimensions for
each individual part to sizes suitable for mounting.
