Overview of VentiAir assembly units
Basic characteristics
Skeletal structure consisting of AL profiles, plastic corners and sandwich panels
The panel filling of the unit is made of polyurethane (PUR) or mineral wool
Panel cladding - galvanized or sheet of stainless steel, RAL according to customer requirements
Service access - side (as standard), bottom (under-ceiling design), or according to requirements and possibilities
The external design of the unit is equipped with a full-area roof with overlaps, material galvanized sheet metal
As a damper base including actuators inside the chambers, intake and exhaust rain blinds as required
Advantages of the used construction
Reduction of energy losses - minimization of heat leaks
High resistance to external atmospheric influences
Smooth inner surfaces of the cladding - easy to maintain hygiene
High resistance of the structure to mechanical damage
Lightweight inspection panels - easy to use
Elimination of condensation and moisture absorption
Insulating material with a very long degradation time
High rigidity and durability of the unit design
