Vents AirVENTS AV - Bespoke units

SIZES AND CAPACITIES OF AIRVENTS AV UNITS

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.

FRAME DESIGN

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.

BASE FRAME TYPES

For both classic and frameless unit casing there are several types of base frame avaliable.

Type	Application (approximately):
Adjustable legs made of 2 mm thick galvanized steel	Single-deck units with air capacity up to 20000 m³/h, or double-deck units – up to 15000 m³/h
Solid base frame made of 2 mm thick galvanized steel	Single-deck units with air capacity up to 35000 m³/h, or double-deck units – up to 25000 m³/h
Solid base frame made of 3 mm thick painted galvanized steel	For unit performance up to 50000 m³/h
Solid base frame made of 4 mm thick painted galvanized steel	For unit performance up to 128000 m³/h
