DYKA AIR. RevolutionAIR
Our times require a
new look at ventilation ducts
A good indoor climate is of great importance
in the modern home with its high insulation
values. In many cases, mechanical air extraction
and balanced ventilation offer the right solution.
The new Bouwbesluit (Building Decree) 2012
also imposed increasingly stringent requirements
here, particularly as regards noise and energy
consumption. Existing systems usually do
not appear to be in compliance with these
requirements.

Innovation based on
experience and the latest
design technology
DYKA has more than 55 years of experience
in watertight and gastight synthetic piping
systems.
We accordingly went in search of the ideal
ventilation duct system armed with this
expertise in piping material, with the demand
from the installation sector and the wishes of
the end user and building manager in mind.

DYKA AIR is designed using CFD
techniques. Using this software to very
accurately simulate air flows, we found the
optimal design with minimal air resistance.
The low resistance of synthetic material
and the cleverly designed auxiliary parts
mean resistance is significantly lower than
in existing systems. This also means less
energy is required to transport the same
quantity of air through the system.
