FAQ
How to install a ventilation duct: guidelinesMore
Correct installation of a ventilation duct is one of the key aspects that determine optimal functioning of the silent kitchen system. The diameter of a duct cannot be smaller than 125 mm. It is advised to minimize the number of bends, to use rounded elbows and smooth reductions. Any acute angles within a duct that hinder unrestrained and rapid flow of air should be avoided.
What type of conductor should be used to couple a fan to a cooker hood?More
It is recommended to use a 3 x 1.5 mm conductor to couple a fan to a cooker hood.
Shall I choose straight away a specific model while deciding to purchase the silent kitchen system?More
No, at this stage it is sufficient to only determine a type of the cooker hood: a wall, a cabinet, an island or a roof model. This aspect impacts a proper selection of fan power with the fan being the most important component of the system. A specific model of the cooker hood can be chosen when the interior of a kitchen is arranged.
Is it possible to modernize an existing solution?More
Yes it is, although a method of solution depends on several factors. An important question is whether in the kitchen are brought out two ventilation ducts. One for the general ventilation of the room, a second for connecting cables from a cooker hood. In older buildings that solution doesn’t always occur. If you change a cooker hood, the best way is use motorless cooker hoods for external roof fans. If you have a cooker hood with built- in motor connected to a separate ventilation duct, you can remove a motor from a cooker hood, mount VILPE® roof fan together with pass- through. In addition for a correct roof fan work you should mount a thyristor regulator.
What is the life span of the roof fan?More
The normal life span of the VILPE® roof fan is about 15-20 years. The motors are long-lived and seldom break down before their time. Should the roof fan for some reason run on low level, the general cause is failure of the condensator. Changing the condensator is a rather rapid operation, but is part of the work of a professional electrician. It may also be due to a ballbearing fault if, during running, a noise is heard from the motor and which increases at higher revolutions. There is a service pack available for each roof fan model. The service pack includes both motor and condensator.
