Wive
The VILPE Wive can be mounted on walls with a thickness of at least 255 mm. If the wall is thicker than 440 mm, additional pipe parts will be needed.
First, make sure that the filter is securely attached to the valve. Attach both the metal parts included in the supporting structure to the mounting holes inside the round plastic part. The metal parts must cross over each other. Pull the white cloth filter over the support structure and fasten it with a rubber band. The rubber band is to be fitted over the recess of the metal parts, not on the plastic part.
Wive intake filters fit wall-mounted Wive intake vents. As these filters are designed specifically for these products, we can guarantee excellent filtering efficiency. If you have a Wive installed onto a window vent, you can also use the Wive coarse filter.
Roof fans
The roof fan should be selected based on the ventilation needs of the building or property. The quick selection table for VILPE roof fans can be used to select a roof fan for an ordinary detached house. To select a suitable roof fan, the pressure caused by the duct system and the necessary air volumes must be known.
Passive ventilation can be upgraded to mechanical ventilation using roof fans from the ECo series in combination with the ECo Ideal Wireless system. ECo Ideal is an automatic and demand-controlled roof fan control system. It can also be used for ventilation in recreational homes, warehouses and garages.
New buildings commonly use a mechanical ventilation system with heat recovery. When renovating older buildings, we recommend the VILPE ECo Ideal Wireless control system.
VILPE E-series roof fans can be used with cooker hoods designed for external fans with AC-powered blower control capability. If the range hood is capable of controlling an EC-model roof fan (0–10V DC), VILPE ECo series roof fans should be used with it. Be sure to check the duct size and control with the cooker hood manufacturer.
VILPE E series roof fans are AC-powered fans. VILPE ECo series roof fans represent next-generation fan technology which is quieter and more energy-efficient than AC models. EC is an abbreviation for ‘Electronically Commutated’, which in the case of a roof fan means a fan with a brushless DC motor. DC motors are about 30 per cent more powerful than AC motors.
See the sections “What criteria should I use when selecting a VILPE roof fan for exhaust air ventilation?” and “Which VILPE roof fans can be used with a cooker hood?”.
The lower pressure drop in FLOW products reduces the power consumption of the ventilation unit. In addition, the roof fans in the series are EC-controlled and have a service switch. FLOW products have:
State-of-the-art water separation
Up to 40 percent less pressure loss (for exhaust pipes) compared to older models
Modern design
A service set should be selected based on the roof fan model, which can be seen on the cowl’s number plate. For example, the E190/E120 service set is suitable for the VILPE E120 and E190 roof fans. Likewise, the ECo220 service set is suitable for the VILPE ECo220 roof fan.
If the number plate has faded or you are unable to find it, the motor type is marked underneath the motor.
The VILPE ECo 110 FLOW roof fan is controlled by an external control panel. It is suitable for applications where separate alarm data is required. The rotational speed can also be controlled by the house automation system at a voltage of 0–10 V.
The ECo110 FLOW can be controlled with an external control panel, and the VILPE ECo motor control panel can be used for regulation.
For ventilation purposes, the appropriate control panel system must always be used. The VILPE ECo Ideal Wireless roof fan system is a wireless, demand-controlled ventilation control system.

Warm air normally rises via ducts and structures, and cold air moves downwards. When a cold surface and warm air come together, and the relative humidity is 100 per cent, a dew point is formed, causing water to drip from the ducts.
Check that the ducts are properly insulated. Insulation thickness on ducts in cold space must comply with building regulations. The thickness of the rockwool insulation on the ducts must be at least 150 mm.
Check that ventilation in the apartment has been adjusted correctly. Usually, ventilation should be adjusted so that there is about 3–5 Pa under-pressure. If the problem cannot be eliminated by adjusting ventilation and insulating the ducts, the range hood should be fitted with a fully closing damper. This prevents humidity from rising in the duct and becoming condensed.
If the fan has frozen up and cannot rotate freely, the automatic thermal relay switches on to prevent the fan from breaking down. When the ice has melted, the thermal relay is reset, and the fan is again operable. The easiest way to defrost a frozen fan is to blow warm air into the duct – for example, with a hairdryer.
The normal service life of VILPE roof fans is 15 to 20 years. The motors have a long service life, and they seldom break down prematurely.
Pass-throughs, exhaust ventilation pipes and other ventilation pipes
Selecting a pass-through is easy with the VILPE pass-through selector. If you cannot find the right alternative from the selector, please contact VILPE technical support.
Underlay seals protect roof structures and insulation material from water condensation on the lower surface of the roof. The seal also prevents any humidity caused by water and snow from entering the intermediate floor through ventilation openings in the ridge. Learn about the VILPE Underlay 2K seal by watching this installation video.
The VILPE Underlay 2K seal is the only pass-through accessory on the market which guarantees that the roofing structures it is installed onto remain fully waterproof. Using the Underlay 2K seal also ensures that natural discontinuity points in the roofing material, combined with winds and driving snow, do not impose any extra humidity load on the roof structures. The Underlay 2K seal effectively seals the pass-through and the roof-covering into a single watertight and wind-tight component. Learn about the VILPE Underlay 2K seal by watching this installation video.
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.
We do not recommend placing a cowl on top of a sewer ventilation pipe. However, a cowl can be used if the intention is to make the sewer pipe look the same as the other pipes on a roof. If a cowl is used, the rain collar inside the cowl should be removed in order to improve ventilation.
Yes, VILPE ventilation pipes can also be used to ventilate roof structures, and where necessary, roof ventilation can be improved using a ventilation pipe.
In many cases, a range hood with an internal blower can be replaced with a range hood which requires an external blower, thereby converting the exhaust pipe into a roof fan. This makes the kitchen much quieter.
VILPE Solar pass-through sets are intended for passing the supply and return pipes of solar thermal collectors, cables and other smaller pipes through the roof. VILPE Solar pass-throughs can be used with all of the most common roof types and roofing materials.
VILPE Ross ventilation poles
It is specified in Section 3.2.1.5, part C2, of the National Building Code of Finland that the total surface area of underfloor ventilation openings must be at least 4 per mil of the surface area of the underfloor space. The Finnish Society of Indoor Air Quality and Climate provides instructions for determining the ventilation needs of different underfloor space types. To determine your project’s specific ventilation needs, please contact a skilled HVAC or structural designer.
For the VILPE Ross 125 ventilation pole, an opening of at least Ø 135 mm must be provided in the foundation, and for the Ross 160 ventilation pole, an opening of at least Ø 170 mm must be provided.Free surface area of the openings for VILPE Ross ventilation poles:
VILPE Ross 125: 95 cm²
VILPE Ross 160: 201 cm²
VILPE Ross 200: 314 cm²
VILPE Ross ventilation poles can also be used for:
