How to choose a fan for a room?

The performance of the fan should be adjusted to the specific room where it will be located. When selecting a fan, you should take into consideration the type of room (its purpose) and its cubic capacity (length x width x height of the room)

We calculate the performance according to the formula:

cubic capacity x air exchange rate for a room

How to mount dRim panel on fan or grille?

The panel on the fan and the dRim grille is mounted in exactly the same way.

From the top, slide the rear part of the panel onto the mounting on the fan or grille until you hear a characteristic click – this sound indicates that the panel has been hooked using a securing element and it is not possible for the panel to detach spontaneously and slide off. To remove the panel, press your finger on the securing element located at the bottom of the panel mounting and slide the panel upwards along the fan or dRim grille.”

I connected the fan and it only worked for 3 seconds? Why?

The first operation of the fan directly after connecting it to the installation is called a test run. The fan will start for 3 seconds and then stop.

After that the fan will work for a specified time depending on the type of fan (S, TS, HS, etc.) and its settings.

What do the symbols on fan boxes mean: S, TS, HS+TS, RS, RMS...?

This designation represents the version of a given fan model. Each domestic fan is available in several versions, differing in the method of activation, operating time, and deactivation. Below is a list of all version designations:

   S   (standard) Basic model. Can be controlled using its own switch, for example, together with the lighting.

   PS  version with a switch. It is connected to a standard socket using a plug and has a switch on a decorative cord.

   TS    (time sensor) timer controller, which ensures that the fan will continue to operate for a specified time, plus a time set on the controller after the power is turned off.

This is useful, for example, after a bath, where moisture is still being expelled even after the user has left the bathroom.

   HS+TS   (higro sensor + time sensor) in addition to the timer controller, it has a humidity sensor, which the user sets within the range of 40 – 80%. The fan activates when the set threshold is exceeded (for example, during bathing) and operates until the humidity level is reduced plus approximately 3 minutes – to maintain the effect.

   DTS   (delayed time sensor)

timer controller with delay. It activates 3 minutes after power is supplied (for example, when the light is turned on with a common switch). If the power is cut off during this time, the fan will not activate. If power is still supplied after this time, the fan will activate and operate until the power is turned off plus for the time set on the controller.

This is useful when the user enters the room briefly, for example, to wash hands or retrieve a needed item.

  MS   (motion sensor) infrared motion sensor that activates the fan when it detects the presence of a user and operates for a specified time.

  RMS   (microwave motion sensor) micro-wave motion sensor that activates the fan when it detects the presence of a user and operates for a specified time.

Where to mount the fan?
Należy zawsze pamiętać, aby wentylator był zamontowany możliwie najwyżej. Musi być umieszczony naprzeciwko miejsc, z których odbywa się wymiana powietrza, z zachowaniem co najmniej 3-centymetrowego odstępu od sklepienia ścian oraz sufitu. Ponadto, powinien być zainstalowany blisko źródeł pary, lecz tak, aby nie można go było dotknąć. Należy również wziąć pod uwagę parametry ochrony IP jakie spełnia dany wentylator.
PAMIĘTAJ! Wentylatory powinny być montowane i demontowane przez wykwalifikowanego elektryka posiadającego uprawnienia SEP.
Which ventilation system is better: round or flat?

Najważniejsze w wyborze rodzaju systemu z pewnością jest dobranie przekroju kanałów do określonych potrzeb czyli wydajność systemu.

Choć preferowany jest przekrój okrągły ze względu na mniejsze spadki ciśnień w systemie przy jednakowej powierzchni przekroju, możliwe jest także zastosowanie przekrojów prostokątnych o zbliżonych parametrach ze względu na ograniczenia przestrzenno-montażowe.

airRoxy oferuje systemy wentylacyjne o przekroju Ø 100 i  Ø 125 jeśli chodzi o system okrągły oraz 110 x 55 mm i 220 x 55 mm w przypadku systemu płaskiego.

What is the warranty period for airRoxy products?

For most domestic airRoxy fans, there is a 3-year warranty.

For industrial fans, the warranty period is usually 2 years.

To familiarize yourself with the warranty conditions of a specific product, go to the “Instructions and Warranty” section or visit the product page and go to the “Documents” tab.

You will find a printed version of the instructions and warranty in the box of each airRoxy fan.

Can I buy directly from airRoxy?

At the moment, we do not conduct retail sales.

You can purchase from us if you run a business. To do this, please contact our export department.

Do I need back valve?

A back valve is a ventilation component mounted on the fan collar or further along the ventilation system that prevents the flow of backdraft air and unwanted odors after the fan is turned off.

In our offer, you will find both back valves mounted on fans (back valve, dRim check valve) and those mounted on ventilation system elements.

What is the airflow of the fan?

It’s the fan’s capacity to move a specific volume of air within a unit of time. Airflow is measured in m3/h. 

All fan parameters, including the airflow, can be found in the ‘Models and Technical Data’ sheets in the descriptions of individual products on the website, as well as in the airRoxy product catalog.”

How to connect and set up the fan with the HS+TS hygrostat version?

The method of connecting to the electrical installation and the method of regulation for all airRoxy fans, including the HS+TS version, can be found on the website under the ‘Connection’ tab in the description of each fan, as well as in the user manuals.

REMEMBER! Installation of the fan should be carried out by a qualified electrician with SEP (Electrical Power Engineering) qualifications.
