System Overview Ventilation Device aV100 ALD

The aV100 ALD is an external wall air diffuser for fresh air supply, complementing extract air devices. It features an insert with an adjustable inner panel, integrated wind protection and filter, a wall sleeve, and an external cover. The air volume is regulated via the inner panel. The filter cartridge ensures clean air intake.

The standard wall sleeve is 495 mm, with longer options available. Both can be shortened on-site.

Components

• Inner panel (insulated / lockable)
• Filter cartridge incl. filter ISO Coarse (G1)
• External closure
• Pollen filter (optional)
• Wall sleeve

Models

The aV100 ALD series differs in external terminations:

• Basic variant: Equipped with a square weather protection grille aV100.
• Plus variant: Equipped with a rain-proof weather protection hood Flex aV100 (available in white/grey/anthracite/special colors).
• Corner variant: For integration into window reveals.
• Nordic variant: For integration into masonry brick walls.

Refer to separate installation instructions for details on external closure variants.

Construction

The aV100 ALD Plus consists of:

1. External closure (Base plate, Drip edge, Cover, Weather protection grille)
2. Wall sleeve
3. Filter cartridge with wind protection
4. Filter ISO Coarse (G1)
5. Inner panel base plate ALD100
6. Inner panel cover ALD 100

Functions

ALD units are installed in supply air rooms connected to extract air devices. Negative pressure from the extract air device draws outside air in. Fresh air outlets have filters and wind protection. Air volume is regulated at the inner panel by adjusting the opening angle.

Installation Example: Aventus extract air system with aV100 ALD for fresh air supply.

Preparing for Installation

Installation Position

Installation location should follow ventilation planning. Exact positioning requires on-site checks and adjustments with the planner/user. Installation near the ceiling (e.g., 1.80 m above finished floor) is recommended for optimal function. Avoid placing the unit above radiators, thermostats, sensitive furniture, or pictures.

Minimum Distances for Wall Opening

Observe minimum distances to components and building elements on both internal and external walls. A minimum distance of 1.2 m is required between adjacent air openings. Ensure the aV100 ALD is not covered and has free airflow. Maintain a minimum circumferential clearance of 250 mm. Installation close to the ceiling improves air distribution.

Recommendation: Install the wall opening above a radiator to pre-heat incoming air. Position the device so air does not flow directly into the occupied zone (maintain 1-1.2 m distance). Each device must be in its own wall sleeve. Minimize inflow air velocity to avoid drafts.

Position of the Wall Opening

Refer to specific installation instructions for other variants. Diagrams illustrate positioning for Basic and Plus variants, including dimensions for the wall opening and the Simplex wall mounting system.

For new constructions, consider the optional Simplex D103 wall mounting system, D120 wall block, or Woodplex for timber construction. Observe minimum distances and installation positions. Consult your planner if unsure.

Create Wall Opening via Core Drilling

Drill a hole with a core drill attachment or milling drill of Ø 115 mm. Ensure the masonry is dry and load-bearing, and that no load-bearing elements are in the drill hole path. The wall opening must have a slope of 1-2° towards the exterior wall.

Installing the Wall Sleeve

Tools required: Measuring tape, angle grinder, spirit level, non-pressing 2K polyurethane foam, cutter, mounting wedge set, styrofoam discs.

Requirements: Wall opening Ø 115 mm is complete. Determine exact wall thickness X and protrusion Y based on exterior rendering (D), insulation (C), masonry (B), and interior plaster (A). Refer to the table for specific calculations based on external closure and inner cover type.

Steps:

1. Cut the wall sleeve to the determined dimension X + Y. File edges.
2. Remove styrofoam discs. Insert the wall sleeve into the opening, flush with the interior wall, ensuring a 1-2° slope towards the exterior wall using mounting wedges and checking with a spirit level.
3. Insert styrofoam discs from inside and outside to prevent contamination.
4. Foam-seal the gap between the wall sleeve and masonry with 2K polyurethane foam.
5. After hardening (approx. 24 hours), cut off excess foam and protruding mounting wedges flush with the inner or outer wall as needed.

NOTICE: Improper slope can lead to condensation water accumulation and damage. Ensure proper sealing to prevent contamination.
