SIZES SELECTION

CASING TYPES

Unit casing provides thermal and sound insulation, as well as durability and protection from external influence.

AirVENTS series are available in several types of casing, general properties of which are:

High Mechanical strength.
Corrosion Resistance.
Thermal insulation.
Protection from thermal bridges.

Increased fire resistance, high quality insulation materials. Mineral wool basalt fiber insulation with 90 kg/m3 density. Unlike other types of insulating materials, this material is completely non-flammable and environmentally friendly.

AirVents series are available in several types of casing

FRAME DESIGN - AVL*

FRAMELESS DESIGN - AVF

Self-support,frameless design - AVN

* Models so marked are not Eurovent certified

Frame design - AVL*

The classic casing design is based on aluminum profile frame, joined by means of cast corners, provides high durability of the unit. Different frame thickness should be used considering the table below:

Frame Type	Recommended area of performance	Aluminum profile thickness	Thermal insulation thickness
50-50	20000-45000 m³/h	50 mm	50 mm
70-50	more than 45000 m³/h	70 mm	50 mm

Casing panels are made of steel sheets with a layer of thermal and acoustic insulation from mineral wool.

Casing panel material varies depending on unit application:

Outer panel surface material:

Zinc-aluminium coating (standard)
Galvanized steel with polymeric coating (high corrosion resistance)
Galvanized steel (for internal execution units)

Inner panel surface material:

Zinc-aluminium coating (standard)
Stainless steel (for units in hygienic design)
Galvanized steel

External realization:

The unit is additionally protected against atmospheric precipitation.
Weather protection hoods are provided at the inlet and outlet air pipes.
Air damper actuators are supplied with protective visors.
Flat or gable roof.
An inspection window is supplied with a protective grille.
The visor length is 300 mm.
All joints are sealed.
All these elements protect the unit against external influence of water, send, leaves, etc.

AVF - Frameless units – approved Eurovent

Frameless design casing system excludes thermal brigdes, usuall for aluminum or steel frame. This significantly increases thermal resistance and reduces heat loss, especially for outdoor installation. It also prevents condensation on the surface when air cooling is on.

Casing panels made of sheet steel with a layer of 40 mm thermal and acoustic insulation from mineral wool.

Casing material varies depending on unit application:

Outer panel surface material:

Zinc-aluminium coating (standard)
Galvanized steel with polymeric coating (high corrosion resistance)
Galvanized steel (for internal execution units)

Inner panel surface material:

Zinc aluminium (Standard)
Galvanized steel with polymeric coating
Galvanized steel

Benefits of frameless casing:

Better thermal resistance. Class T3, according to EN 1886.
Protection from thermal bridges. Class TB4, according to EN 1886.
Higher mechanical strength. Class D1, according to EN 1886.
Minimizing air leakage. Class L1, according to EN 1886.
Lower weight of the unit.
Suitable for outdoor installation.
