Q- How can be solved the problem of humidity and/or mould in cellars or in highly wet rooms?
A- Installing an O.ERRE fan equipped with an Humidistat (marked with the final letter “ H ”), can be easily solved  the problem of humidity and mould. The fan will start working automatically when the humidity value of the room exceeds the preset (adjustable) value. When the humidity level move down to the preset rank, the fan will overrun according to the pre-set overrun timer period. The fan could also be turned on manually if necessary.   

Q- A Which fan can be installed in environments with low noise level?
A- In the O.ERRE catalogue can be found several fans working with a very low noise level. Just for example considering duct applications, the range of SILENTE (centrifugal) and INTRA (false ceiling mounted centrifugal), can be positioned at the top of the market in terms of silent running. On the other hand, just considering window, wall or panel mounting, installing the Smart series (axial) equipped with a controller, noise level could be reduced accordingly to a reduced air flow required. Noise level data of each O.ERRE product can be found in our Catalogue in the related column dB(A).

Q- Is there any extractinc fan specially designed for fumitory pipes or chimneys?
A- YES, the roof fan TURBOCAMINO is designed to extract hot fumes up to 200° C and can be installed on top of fumitory pipes, chimneys, oven exhaust, etc. to make easier the fume extraction while avoiding smoke return into the environment

Q- I need to ventilate a cooling electrical cabinet or enclosures with a specific IP protection, is it possible to keep the same IP level of the electrical cabinet installing a fan?
A- YES, the range of fans SYSTEMA has been specially designed for this purpose. The range of SYSTEMA, can match the most used and common protection from IP43 to IP55. SYSTEMA maintain the original IP protection even if the fan is working.

Q- I need to install a fan in a room where the light is always turned on and I don't want the fan running all day long. What do You suggest?
A- The O.ERRE fans with SENSOR or PIR have been designed to detect the presence of people in a room where it is installed. According to this solution the fan will start working automatically only when necessary, and after the room will be vacant the fan will overrun according to the pre-set (adjustable) overrun timer period. Moreover these products are very simple to be installed because can be connected to the two existing cables, available in any environment (Live & Neutral) .

Q- Which controller di I need to regulate the speed of a domestic fan?
A- Our basic domestic fans (not automatic) can be regulated through the electronic controller RGE, while the automatic axial fans VENTILOR AR & SMART AR can be controlled through RG5 AR.

Q- Is there any in-line domestic fan totally recessed?
A- YES, the TB series has been designed to be installed in standard piping ( 100-125-150mm) to be totally recessed. The holes can be covered with the optional grilles .

Q- Is it stricly needed to create a hole for the incoming air in a room where a domestic or industrial fan has been installed?
A- YES, otherwise the air replacement would not be possible and the fan action would be useless because, in order to have a proper ventilation, extracted air must be replaced by the same quantity of incoming air. In our Catalogue You could find the necessary grilles for this purpose.

Q- Can a fan be installed in a room containing a gas device heater or baking?
A- No YES, but the section of the aeration hole of the environment must be upgraded as follows:

of 140 cm2, if the flow rate of the fan is less than 50 m3/h,

of 280 cm2, if the flow rate of the fan is between 50 & 100 m3/h,

of 420 cm2, if the flow rate of the fan is between 100 & 150 m3/h (refer to UNI-CIG 7129 capt. 3.4) .

Q- I need to create a ventilation system in a false ceiling. Which kind of fan do You suggest?
