Exposed air handling and cooling equipment
Hiding roof or ground mounted equipment while attenuating unwanted noise and allowing necessary airflow can be accomplished with AMCA Certified acoustic louvers.
Data Centres
Mission-critical facilities must balance demanding ventilation requirements with the need to minimize noise impacts on surrounding communities. Ventex and Alumavent provide AMCA Certified architectural ventilation solutions that help project teams address acoustic performance, airflow, weather protection and air control.
Community acceptance starts with noise control

Engineered Performance. Independently Certified.
Data centre facilities move enormous volumes of air through limited façade areas, often on sites close to residential neighbours. AMCA Certified Ratings for sound, airflow and water penetration provide independently verified performance data, giving owners, developers and design teams confidence that specified performance requirements are supported by tested results — not simply claimed.

Four Critical Ventilation Challenges
Engineered solutions from Ventex / Alumavent
For noise limits at the property line
1240 & 1245
ACL1240 / ACL1245 — 12" Acoustic Louver
A 12 inch deep formed aluminium acoustic louver that attenuates equipment noise while still ventilating. Used where generator yards, chillers and air handling plant sit close to neighbours.
For driving rain on exposed façades
2570V
2570V — 5" Wind Driven Rain Louver, Vertical Blade
AMCA certified for both wind-driven rain and air performance. The channel frame suits duct-mount intakes on elevations that take the weather head on.
For high air flow in constrained openings
2630DC & 2635DC
2630DC / 2635DC — 6" Deep High Free Area Drainable Louvers
A six inch drainable louver whose head and blade design sheds water while keeping free area high, so pressure drop stays low across large intake banks.
For controlling ventilation air leakage and heat loss
3960
3960 / 3961 / 3965 / 3967 — Insulated Extruded Aluminum Control Damper
Low-leakage, insulated thermally broken dampers minimize unwanted airflow and heat transfer when closed, helping maintain controlled indoor conditions and reduce HVAC energy losses.
Community acceptance starts with noise control
Data centre approvals increasingly turn on sound, not air. Standby generators, chillers and air handling plant all run against property-line noise limits that are written into the planning conditions long before the mechanical design is fixed. Acoustic louvers used in intake or exhaust wall openings or as rooftop equipment screens allow the airflow to take place where needed while attenuating unwanted sound. Computer simulated acoustic analysis is helpful in assisting the design of acoustic louvers but physical lab testing of the actual product is necessary to verify its actual performance. Ventex has a line of acoustic louvers that are AMCA Certified for Sound, Air Performance and Water Penetration.
Specified for how data centre sites actually behave
Every elevation on a data centre campus asks something different of the louver line. These are the four conditions that most often drive product selection.
Containment and separation
Data centre HVAC systems require effective airflow isolation to maintain controlled operating conditions. Low-leakage, insulated thermally broken dampers minimize unwanted air infiltration, heat transfer and condensation when ventilation openings are closed.
Modular cooling plant
Skid mounted plant arrives with its own intake and discharge requirements. AMCA certified louver and damper product data sheets let the equipment manufacturer know the actual performance meets their needs.
Maintenance access
Dense service routings behind the facade can make access to maintenance of dampers, filters, louvers and birdscreens difficult from the interior side. Louvered access doors on the exterior can allow cleaning and maintenance to take place with minimal downtime.
Engineered performance, documented
AMCA certified
Air performance, water penetration, sound attenuation and leakage ratings come from AMCA-certified third-party testing, so you can have confidence specified performance will be met.
Free area where it counts
High free area profiles keep pressure drop low across large intake banks, which protects fan energy over the life of the facility.
Acoustic attenuation
Published sound attenuation results are AMCA Certified. While computer simulation is a valuable design tool, it is critical that the louver is third party tested to confirm its performance at different frequencies.
Thermally broken dampers
Insulated blades and co-extruded seals hold ultra-low leakage down to −40 °F, protecting the envelope when the economiser closes.
Custom made to the opening
Panels are fabricated to the opening rather than assembled from stock sizes, which matters on the oversized penetrations typical of data halls.
Submittal support
Drawings, performance data and schedules are prepared against the specific project, so the contractor gets exactly what the submittal needs.
