Exhaust ventilation pipes

High-quality exhaust pipes from VILPE bring out dirty and humid air out of the building. In the assortment, you will find sewer pipes, cowls and ventilation pipes for optimal ventilation. Find the right product here.


Which sewer ventilation pipe Ø 110 mm should I choose: an insulated or an uninsulated one?

Given the prevailing conditions in the Nordic countries, an insulated sewer ventilation pipe model should always be used. Only an insulated sewer ventilation pipe prevents the condensation of humidity in the sewer and the accumulation of ice in the pipes. It the pipes freeze, sewer ventilation will not work, which may lead to the emptying of water seals and cause a bad smell inside the building.

Can I use VILPE ventilation pipes to ventilate roof structures?

Yes, VILPE ventilation pipes can also be used to ventilate roof structures. Where necessary, roof ventilation can be improved using a ventilation pipe. Thanks to its structure, the ventilation pipe improves ventilation. When ventilation pipes are used for ventilating structures, it must be ensured that any water condensing onto the pipe walls is directed to a place where it does not cause damage to structures. For example, this can be done by placing a plastic container of about one litre under the ventilation pipe to collect and evaporate condensation water.

Can a VILPE exhaust pipe be converted to a roof fan without replacing the whole product?

In many cases, the range hood with internal blower is replaced with a range hood that requires an external blower, and the exhaust pipe is thereby converted to a roof fan. This makes the kitchen more silent.

If there is a need to convert an exhaust pipe to a roof fan, we recommend that the exhaust pipe be completely replaced with a VILPE roof fan. The package is then tested and ready for operation, and no separate wiring is needed. Waterproofing can only be ensured by means of a readymade component.

The cowl of the most widely used ventilation exhaust pipe, the Ø 125 mm pipe, can be replaced with the VILPE S series VILPE E120S roof fan. The cowl of the exhaust pipe is removed and replaced by a fan that is attached to the exhaust pipe from its lower part with three screws.

Converting an exhaust pipe of Ø 160 mm into a roof fan using the VILPE E220S fan is slightly more difficult, because in addition to removing the cowl, the plastic cone-shaped air deflector between the exhaust pipe and the cowl must be removed.

It must be noted in the case of conversion that a separate pass-through must be provided in the roof for the fan’s electric wire. According to fire regulations, electric wires cannot be directed to the controller via the duct system. In many cases, a hole is made in the plastic pass-through for the electric wire, and the gaps are then sealed using a cable pass-through and sealing mass.

NOTE! Electrical installations in connection with changes and installations may only be carried out by professional electricians.
