TopVent CK ZR (AK+)

Aesthetic window vent for compact transom mounting

TopVent CK SR is a self-regulating window vent that can be quickly and easily installed behind the exterior cavity wall, making the vent invisible from the outside. With an optional exterior cover, the grille can also be placed in plain sight (SkyVent CK SR (AK+)).

  • Optimal aesthetics thanks to "invisible" punching
  • Installation on any type of window (wood, aluminum, plastic or steel)
  • Upward airflow for a healthy and comfortable indoor environment
  • Acoustic attenuation up to 40 dB

Acoustic comfort

The window vent has the highest airtightness class and is available in 3 different variants.

Ranging from a standard vent without acoustic attenuation to an AK version for situations with light noise load or the AK+ for situations with a heavy noise load. The AK+ vent provides a maximum acoustic attenuation of 40 dB.

Combinable in terms of installation and installation height

The TopVent CK can be combined with other window vents in the TopVent range. A variant is available for any installation situation and any window type.

TopVent BE SR (AK+) for installation on top of the window frame

SkyVent BE SR (AK+) for installation on top of the window frame up to heights of 70 m

SkyVent CK SR (AK+) for compact transom mounting up to heights of 70 m


Specification
  • Self-regulating flap window ventilator PQ mm DUCO Ventilation & Sun Control - TopVent CK SR (AK+)

    Description

    The TopVent CK SR is a thermally insulated aluminium self-regulating flap window grille with self-regulating flap for the supply of fresh air in the living areas. The vent is equipped with a 15 mm flange for mounting in a recess. Optionally available in an acoustic version for situations with light (AK) and/or heavy noise exposure (AK+).

    The standard self-regulating flap ensures energy gain and a constant flow rate. The flap ensures that the ventilation volume remains the same in case of increasing wind, i.e. the increasing wind is smoothed out. The flap responds excellently at a pressure difference as low as 1 Pa, avoids draughts and limits energy loss and overventilation. The length of the operable flap kan be limited according to the desired or required flow rate.

    The inner grid with invisible perforation is easily removable, washable and insect repellent. The inner cover provides an upward air flow and comfortable indoor climate (Coanda effect).
