Passivent Window Aircool Ventilator - Standard/Thermal/Acoustic versions

Application

A range of controllable insulated ventilators for installation in the walls of external facades or within buildings. Provide controlled air intake & extract in natural or mechanical ventilation systems.


Available as standard, thermal or single baffle and double baffle acoustic versions.


See separate NBS entry for Aircools suitable for wall installation.

Description

Passivent Aircool® is a range of controllable insulated ventilators primarily for installation in external facades or within buildings.


Provide controlled air intake & extract in natural ventilation or mechanical ventilation systems.


Three types of Window Aircool are available:



  • Standard.
  • Thermal.
  • Acoustic (single baffle or double baffle).


Supplied with internal sleeve to house the motorised elements.


Integral electrically actuated low voltage dampers control air intake and extract and provide optimum safety and flexibility whilst also being virtually silent in operation


Particularly suitable for night cooling strategies where daytime heat build up is dissipated from the structure during the night, producing lower internal air temperatures with a reduced need for daytime cooling or air conditioning.


Improved insulated internal dampers provide a superior U-value as low as 0.86W/m2K when closed, to minimise heat loss.


Weather performance:

Excellent weather protection and security are provided by the external weather louvre, even when the internal insulated louvre is open. This allows the units to remain open even in inclement weather conditions.


The external louvres provide 98.6% (Class B) rain rejection when independently tested to BS EN 13030. When tested to BS EN 1027 the closed ventilators are watertight at over 1000Pa pressure.


Air leakage performance:

Excellent airtightness performance when closed


When tested the air leakage rate of the closed ventilators is 0.57 m3/hour/m at 50Pa pressure. The linear metre length

is defined as the perimeter of the unit plus total length of the louvre-to louvre contact. This equates to an approximate value in terms of area of 9.7m3/hour/m2 at 50Pa pressure (depending on unit size).


Internal cover grilles supplied as standard. Heavy duty version available to protect against damage in applications such as gyms or sports halls.


Thermally broken frame, and insulated and orientated dampers

minimise the risk of nuisance condensation and draughts.


Ventilators can be controlled by Passivent's range of thermostatic controls or programmable controllers linked to a building energy management system.


Passivent also offer a range of control sensors for temperature, CO2 and wind for exposed locations.


Aircool ventilators and the various elements that make the total unit can also be supplied in modular form, with the external weather louvres (also with the double bank louvre system), internal insulated dampers and internal cover grilles as separate components, providing extra flexibility in ventilation design


4mm insect screen included.


Thermal Window Aircool:

Has all the features and benefits of the standard Aircool but also incorporates a low resistance airflow heater coil which has been specifically designed for natural ventilation systems and is connected into the main central heating system of the building.


An integral sensor clipped to the coil reports the temperature of the incoming air so that the water flow and temperature can be regulated via third party heating controllers.


When combined with the Passivent range of natural ventilation controllers the motorised damper ensures the correct level of ventilation is supplied.


Acoustic Window Aircool:

Developed to meet the increased regulation requirements for sound reduction.


Independent test data to BS EN 20140-10 is available on request with detailed performance figures for each application.


Depending on requirements acoustic ventilators may have a single or double row of internal acoustic chevrons, acoustic liners.


For special high noise reduction requirements, Passivent can design and manufacture bespoke ventilators to maximise sound reduction and minimise airflow resistance so as to achieve target air change rates.


Passivent Aircool acoustic facade ventilators can be complemented by Passivent Soundscoop and Soundscoop iAT (intelligent airflow technology) acoustic ventilators for internal air transfer.
