Type FSL-B-ZUS


Decentralised sill units type FSL-B-ZUS supply the building with conditioned fresh air.

In addition to mechanical ventilation and air filtering equipment with this approach ensures the heating and cooling of the offices.

FSL-B-ZUS
FSL-B-ZUS
Supply air units with secondary air function:

  • Mechanical ventilation
  • Installation on the sill beside the window
  • Quasi displacement flow with 2-way air discharge
  • Heat exchanger for heating and cooling
  • Energy efficient radial flow fan
  • Fan speed control in 3 steps
  • Controlled/limited fresh air flow rate independent of wind pressure
  • Low sound power level

Supply air units maintain a high air quality in rooms by supplying outdoor air to the room. For the discharge of the air, the unit has a radial fan.
The fan takes in outdoor air, which flows through a volume flow limiter, a non-return damper, a shut-off damper and a fine dust filter. These components prevent the exceeding of the dimensioned outdoor air flow through wind pressure, the switching of the flow direction in case of a negative pressure on the façade and uncontrolled flows when the device is turned off. The F7 fine dust filter complies with the hygiene requirements of VDI 6022.
For the thermal conditioning of the outdoor air heat exchangers for air heating and cooling are used.
For output adjustment, the fan is operated in three stages. In stages 2 and 3, the supply air is greater than the outdoor air flow. The difference is taken in as room air near the floor and admixed to the outdoor air. A system-powered secondary air damper controls the room air flow rate.
Similar to displacement flow, the supply air flows into the room through the grille.
FSL-B-ZUS
Under sill units type FSL-B-ZUS with supply air and secondary air function are used for decentralised ventilation and for heating and cooling of rooms and buildings. The devices are manufactured according to specific project-site conditions. The under sill units consist of a casing made of galvanized steel, which axle is integrated into the façade.
The modern under sill units type FSL-B-ZUS axle are directly integrated into the façade above the sill.
