In order to discharge smoke and pollutants from the vent pipes and also as industrial hoods, vane caps are used, which can be made with galvanized sheet and oil sheet. New ventilation canalization company provides all kinds of vane caps with quality material in desired dimensions. You can contact the consultants and sales experts of this company to place an order.
Wing cap made by the new ventilation company
As we said, vane hoods are generally used to cover the riser of the facilities on the roof, engine room chimney, facilitated carbon oxide discharge from the fireplace and package, discharge of smoke and pollutants from the vent pipes, and also as a cap for industrial hoods. This base and air outlet grills are the two main parts of the vane cap.
The vane cap (louver roof ventilation valve) of new ventilation is produced from black iron and galvanized sheet in different dimensions, shapes and colors (electrostatic paint). The body, vane, crown and water of Chegan are considered as components of the vane cap, which are connected by CO2 welding in the new ventilation factory.
Body - Base: All components are mounted on the body. The height of the body is 30 to 35 cm in standard mode, but it can be changed.
Blades: Blades have an angle of 35 degrees and are designed to prevent the penetration of wind and water. The distance between the blades is 5 cm and each cap has 4 blades which can be changed depending on the need.
Note: One of the most important factors in increasing the efficiency of the vane cap in smoke evacuation is the calculation of the height of the base and the number of vanes of the cap.
Crown: The crown is the highest part of the cap, which prevents water from penetrating the pipes and chambers like an umbrella.
Drip water: rainwater enters the roof and walls through the holes created for the cap screws. The dripper was designed for the first time by a new ventilation system that prevents this from happening.
The roof ventilation louvre valve made by Shirken New Ventilation, transmits fresh air from the roof and discharges unpleasant air from inside the building.
The type of feathered caps
The finned cap is often made according to the customer's request, and there is no restriction in determining the type of sheet and its thickness or its dimensions, but usually oiled sheets and galvanized sheets are chosen to make finned caps.
The installation of winged caps is very simple and easy and is done using screws and dowels in such a way that you screw the three-centimeter edge of the winged cap to the seat.
Spot welding can be used to connect the finned cap components (in normal dimensions) made of one mil sheet and less, and to connect the components of large finned caps with a sheet thickness of more than 1 mil, welding should be done. is used
tip :
In order to avoid premature wear of the finned cap in chimneys with high temperature pipes, a thick sheet with fire-resistant color should be used to make it.
Since the vane caps are always exposed to temperature changes and heating due to the turning on and off of the burner of the engine room boilers, a furnace paint coating should be used on the back and on the vane cap.
Advantages of installing a new ventilation vane cap
The feather caps are designed in such a way that it is impossible for rainwater or snow to enter the interior and the bottom of the cap, so it does not need to be sealed with glue or other waterproof materials. In addition, the Z-shaped grill design prevents dust, fine dust and other contaminants from penetrating into the structure of the blade cap.
If the four sides of the winged cap are free (there is no obstacle like a wall), it is possible to make four sides of its grill. But if there is one or two sides of the wall around the wing cap, the wing cap is made in two or three sides.
The wing cap can be installed on the roof, wall and even the facade of the building.
In order to provide free and fresh air to the room of the air-generating devices, a vane cap can also be used.
You can also use finned caps to beautify the unsightly appearance of the ends of the vent pipes on the roof. It is possible to design the outlet of all the vent pipes together and order a vane cap with the required dimensions from the new ventilation company.
Among other advantages of using wing caps, it can be mentioned that it can be installed on normal flat roofs and sloping roofs.
The blade cap can be made and used both in square and round shape with round blades.
What should be done if the gunya feather cap does not work?
Normally, a feathered cap is made square and gunya, but in the situation where the feathered cap is not gunya and it is so-called Qanas, the feathered cap should be made according to the template of the base using the pattern and quadrangular corners of the seat.
Appearance characteristics of vane caps
The number of blades or grills of the blade cap is four blades and the standard height of its base is 30 cm, however, it is possible to change the height of the blade cap base at the customer's request and it is not prohibited.
It is possible to design the roof of the wing cap in "one slope", "double slope" and "crescent" shapes. An edge of three centimeters outwards or inwards is installed in the lowest part of the base of the feathered cap for the purpose of the seat type of the feathered cap.
It should be noted that according to the pressure of smoke or pollutant output from the chimney pipes, the number of blades of the cap is determined.
