Ventilation sockets – rotary, fixed and ventilation roofs
The chimney cap is a chimney topped that stabilizes the string and protects the wire from reversing flow, rain and birds. It is installed wherever the wind, adjacent building, or tall trees disturb the work of gravity ventilation. In this category you will find 28 products: turbowent turbine plant in diameters from 150 to 300, ROTOWENT DRAGON combustion plant, adjustable versions 0–45°, DA and WDA ventilation roofs from 100 to 315, CAGI cylindrical vents and EPDM sealing flanges. Prices from 35 zł, shipping from a warehouse in Kielce.
Three product groups in this category
Product range is divided into rotary Seeds ( wind driven, actively supporting the string), solids (lents and vents without moving parts) and EPDM sealing flanges, which are made of tight passage through roof covering.
What problem do you solve – this is the policy you choose
| Problem or situation | Relevant product | Why this |
|---|---|---|
| Back in the grids, weak gravitational ventilation | Rotary cap fi 150 or fi 200 (aluminium, chromonicel) | Rotating head produces vacuum and forces exhaust regardless of wind direction |
| Smoke or exhaust pipe with thrust problem | ROTOWENT DRAGON RO150 or RO200 | Manufacturer’s design for exhaust pipe |
| Chimney from the vertical, roof with a large drop | Rotating socket 0-45° TU150OCAL-N / TU200OCAL-N | Adjustable angle allows you to set the head vertically despite tilting the base |
| Large wire, ventilation of the economic facility | Turbowent fi 300 on TU300-OCAL-BIII collar | Largest available diameter, flange mounting |
| Protection of the outlet from rain and snow, without supporting thrust | Ventilation roof DA or WDA, fi 100–315 | Simplest and cheapest solution, no moving parts and maintenance |
| Stable hose exhaust without rotating elements | CAGI WCG-100 cylindrical air vent to WCG-200 | The shape uses windflow, and the design is maintenance-free |
| Sealed passage of chimney or pipe through roof | Collar EPDM 22–144, 102–203 or 200–335 mm | Flexible rubber adjusts to the diameter and profile of the cover |
Rotary or fixed socket – what to choose?
Rotating device actively supports ventilation: Wind energy puts the head in motion, and this produces a vacuum in the chimney and increases the exhaust. It makes sense where the string is a real problem – with a short chimney, buildings covered with trees, recurring smells or moisture in the bathroom. Fixed cap, i.e. roof or vent, only protects the outlet before precipitation, birds and partly before gusts. It costs several times less and does not require maintenance, but does not improve the thrust in the chimney that does not have it. So the choice is simple: you have a string problem – rotary seed; you want to shield the working wire – fixed seed.
Important: Ventilation plant is not always suitable for smoke chimney
The bases differ from the acceptable scope. The model intended for ventilation ducts does not need to be designed to work with hot exhaust from the boiler or fireplace. Use only on the smoke or exhaust chimney the cap which the manufacturer has allowed to the fuel and the hose – ROTOWENT DRAGON series is designed for such applications. The installation of the plant on the exhaust pipe is worth consulting with the chimney sweeper, and after the work is done confirm the accuracy and accuracy of the chimney assessment.
How to choose the diameter of the seed?
The rule is one: the root diameter must correspond to the cross section of the cable on which you mount it. The narrowing of the outlet reduces the flow and can worsen the situation that the planting was supposed to fix. The typical ventilation units in single-family homes are used for 150, with larger wires and with collective chimneys – for 200 or more. On a brick chimney with square cross-section, an adaptation base will be needed to fit the face dimension; on circular channels, the seat is placed directly on the pipe or on the flange.
Installation and operation – 5 principles
- The rotary cap must stand perfectly vertically. The deviation from the vertical loads the bearing and shortens the life of the head – use the adjustable version 0–45° at the inclined base.
- Keep the air flowing. Even the best seed will not draw air out of a room where nothing comes; sealed windows require air vents or vents.
- Seal passage through roof with EPDM collar selected to diameter and type of cover – this is the most common place for leaks after installation.
- Check the rotary cap once a year. The head should spin freely at a light gust; resistance means a soiled or worn placenta.
- Work on the roof with the insurance. Mounting at height entrusts the person with appropriate experience and security.
Complete installation
Inputs are usually ordered together with other components of the outlet and the air supply: EPDM flanges, chimney grates, wall vents and window fans. When gravity is insufficient, the alternative is roof fan or recuperation.
Why buy a fix in Wentec
We run a wholesale warehouse with more than 2000 indexes, so the seat, sealing collar and mounting fittings will be completed in one order. We offer products of recognized producers, including Darco. We send in the whole Poland, and in Kielce and Świętokrzyskie voivodship we deliver the goods by our own transport. Describe your problem – the type of chimney, its dimension and symptoms – writing on info@wentec.pl or by text on 606 376 838And we'll pick the right solution.
The most common questions about chimney beds
Does the rotational plant work when there is no wind?
The head does not spin, but the chimney still works gravitationally – the seat does not block it. Small air traffic is enough for the turbine to start turning and supporting the exhaust.
Does the rotary plant make noise?
The properly mounted and efficient planting works quietly. Sands and tapping usually appear with worn bearing or vertical mounting.
Will the plant solve the moisture problem in the bathroom?
It will help if the cause is a weak string in the chimney. If the problem is the lack of air supply to the apartment, there will also be a need for window air vents or wall air vents – without air vents.
How is the ventilation roof different from the cylindrical vent?
The roof is a simple cover over the outlet to protect against precipitation. The cylindrical air vent has a housing using the windflow, making it more stable for the exhaust, although both solutions remain maintenance-free.
How do I seal the chimney passage through the roof?
The flexible EPDM flange is selected to the diameter of the pipe and to the type of cover – sheet metal, trapezoidal sheet metal or tile. The collar cuts to the dimension and attaches to the panel with the seal.
