ROOF FAN VALLOX EXXEO 700

Stylishly designed and acoustically quiet Vallox Exxeo roof fans excel in a wide variety of applications thanks to their versatile size and control options.

The weather-resistant Vallox Exxeo can be installed even in demanding climates, as the zinc-magnesium coated steel sheet (environmental corrosion class C4, painted C5) effectively protects the unit against corrosion. Thanks to its carefully designed structure, rainwater is directed to the side of the unit, preventing water from entering the duct. The perforated roof panel also protects the duct from leaves and other debris.

The noise level of the roof fans is significantly quieter than previous models due to sound-dampening elements in the side panels. All control units for the roof fan are integrated inside the unit behind the safety hatch. Serviceability is enhanced by a tilting function that allows the roof fan to be rotated sideways for maintenance of the ductwork and equipment. The safety switch supplied with the product is pre-installed and wired, and the tilting component is sealed.

The roof fan can be installed on a site-built penetration or using a factory-made Vallox Exxeo roof penetration. With lifting brackets, the roof fan can be easily and safely lifted onto the roof. When replacing an existing roof fan, the standard mounting frame simplifies installation. The roof fan can be painted at the factory in a RAL color to perfectly match, for example, the roof color.

A suitable roof fan size is selected from seven size options based on required air volumes. The air flow of the Vallox Exxeo 700 at 150 Pa pressure loss is 700 liters per second.

Three control variants are available in the roof fan series: the versatile basic model Vallox Exxeo, the Vallox Exxeo DPC (Differential Pressure Control) equipped with an integrated differential pressure transmitter, and the two-speed Vallox Exxeo DS (Dual Speed) model designed for renovation applications.

Vallox Exxeo 700 basic model

Both the basic model and the DPC model, which is controlled by duct static pressure or air volume, feature a display with clear setting buttons below. The controller allows the fan to be set to run at a constant speed, adjusted via 0-10 V control voltage, or operated with two-speed control (Low/High). The controller can also be connected to a Modbus bus. Additionally, operating and alarm data can be sent directly to the monitoring center.

The basic model can be equipped with an external temperature sensor, allowing the roof fan’s speed to be reduced as needed during winter when outdoor temperatures drop.

Additional accessories included in delivery: The control board is included in delivery, but the controller itself must be ordered separately.
