Deflector base D680 | painted steel | brown
Code: 28122Painted steel roof base D680 with a round spigot. Allows a D680 rotary deflector to be installed with a tight seal when the ventilation duct ends at roof level.

Painted steel deflector base D680
The base is a roof plate with a round spigot onto which the rotary deflector is fitted. It is needed when the ventilation duct does not project above the roof or when the deflector needs a firm and sealed base.
Key point
The plate covers the opening in the roof, and the spigot forms a tight joint with the D680 deflector. The brown paint coating applied to the steel adds colour and extra protection – the deflector matches brown roofing. Choose a base and deflector of the same material – mixed metals corrode faster.
Connection diameterD680 mmMaterialPainted steelTypeRoof baseColourBrown⚠ For ventilation only
The deflector is intended for ventilation ducts only – to extract humid and warm air. Do not install it on flues of stoves, fireplaces, sauna heaters or boilers: hot flue gases and acidic condensate will damage it, and there is a risk of fire and carbon monoxide (CO) poisoning.
How it works
- The plate is placed over the roof opening and fixed with screws.
- The joint with the roofing is sealed with sealant or a gasket.
- A deflector of the same D is fitted onto the spigot.

Responsibility for installation lies with the qualified specialist performing it. UAB „Elektrotechnikos sprendimai“ is not liable for installation or possible errors.☝ Elsprendimai.eu recommends:- Painted steel rotary deflector D680 – same material and size.
- All painted steel products – in the subgroup.
✓ Pros
- Tight joint between the roof and the deflector
- Firm base – the deflector does not wobble in the wind
- Same material as the deflector – no galvanic corrosion
- Suitable for new and renovated roofs
→ Limitations
- Screws and sealant not included
- The joint with the roofing must be additionally sealed
⚠ Installation and maintenance
- The base D must match the deflector D.
- Fix with screws suitable for the roofing; seal with a UV-resistant sealant.
- Leave a slope at the joint for water to drain – water must not collect at the spigot.
- Roof work is work at height: use fall protection equipment.
FAQ
When is a base needed?
When the ventilation duct ends at roof level or the deflector needs a firm base.
Can the base be used with a deflector of another material?
Technically yes, if the D matches, but we recommend the same material – this avoids galvanic corrosion.
Are screws included?
No – choose screws and sealant according to the roofing.
Is it suitable for all roofing types?
The plate suits most roofing types; on profiled roofing, seal the joint additionally according to the roofing manufacturer's instructions.
In short
Painted steel base D680 – sealed and firm installation of a D680 rotary deflector on the roof. Choose together with a deflector of the same material. Unsure about the size or roofing? Send us the duct diameter and roof type – we will help you choose.

Please refer to the technical specification.ManufacturerGalvanized steel - coated with liquid zinc, providing additional protection against corrosion.
Stainless steel - strong, resistant to corrosion, oxidation, and other factors.Galvanized steel and stainless steel are two different types of steel, with the main difference related to their corrosion protection methods and chemical properties. Here are the key differences:
Corrosion Protection:
Galvanized Steel: This is steel coated with a layer of zinc. Zinc acts as protection against rusting, as it oxidizes first and protects the steel. This is particularly useful when steel is used outdoors or in areas exposed to moisture.
Stainless Steel: Stainless steel naturally resists rust and corrosion because it is alloyed with chromium (at least 10.5%) and other metals (such as nickel), which create a protective oxide layer on the steel surface. This layer prevents water and air from directly affecting the steel surface, making it highly resistant to corrosion.
Chemical Properties:Galvanized Steel: The zinc layer protects the steel, but it is not as resistant to rust as stainless steel. If the zinc layer is damaged, the steel may start to rust.
Stainless Steel: Due to its composition (chromium, nickel), stainless steel is much more resistant to corrosion and oxidation. It does not react with acids or alkalis and remains rust-free for a long time, even under harsh environmental conditions.
Cost:Galvanized Steel: Typically less expensive than stainless steel because its manufacturing process is simpler and requires lower costs.
Stainless Steel: Due to its more complex manufacturing process and expensive additives (chromium, nickel), stainless steel is more expensive than galvanized steel.
Appearance:Galvanized Steel: Generally has a silvery-gray color with a visible zinc layer. It provides a protective coating but may be less aesthetically pleasing than stainless steel.
Stainless Steel: Often has a shiny surface and is more aesthetically appealing.
Temperature Resistance:Galvanized Steel: The zinc layer starts to melt at high temperatures (above 419°C), so galvanized steel is not suitable for very high-temperature environments.
Stainless Steel: Stainless steel performs well at high temperatures, making it suitable for use in high-temperature applications.
Summary:Galvanized Steel is cheaper and suitable for areas where high corrosion resistance is not required, and appearance is not a primary concern.
Stainless Steel is more expensive but has significantly better resistance to corrosion and high temperatures, as well as better aesthetic appearance.This product is marked with the CE label, which confirms that it complies with all applicable European Union directives and regulations.
