Rotary longitudinal nozzle Ø150 aluminum NOP150AL

Functional solution for improving ventilation draft

Installing a longitudinal rotating cap with a diameter of 150 mm is an effective way to increase the efficiency of gravity ventilation systems. The device, made of aluminum sheet, utilizes wind energy to create negative pressure in the chimney duct. This ensures smoother air exchange within the building and minimizes the risk of backdraft. This simple yet crucial component of the installation protects ducts from atmospheric precipitation such as rain and snow.

Construction and practical application

The primary function of this element is to rotate under wind influence, generating additional draft in the chimney. Regardless of wind direction, the cap adjusts its position to maximize ventilation efficiency. The aluminum construction ensures resistance to corrosion and weather conditions, resulting in a long service life without the need for frequent inspections or replacements.

• Improved draft continuity: Increases chimney draft strength, which is particularly important on windless days or when natural ventilation is weak.
• Moisture protection: Prevents ventilation ducts from becoming damp due to rain and snow.
• Universal mounting: Designed for pipes with a diameter of 150 mm, ideal for standard residential and industrial installations.
• Material durability: Aluminum sheet is lightweight yet mechanically robust and resistant to rust.

Application and benefits for the installation

This product is suitable for both new buildings and the modernization of existing ventilation systems. Its installation does not require complex tools or specialized knowledge – it simply needs to be correctly fitted to the existing duct. For installers, this means quick project completion, while end users benefit from stable ventilation system performance over many years. It is worth noting that improved chimney draft directly translates to better indoor air quality and reduced energy consumption for heating (in systems with heat recovery).

By choosing this model, you receive a product of Polish manufacture that combines simple construction with high operational effectiveness. This is the solution for those seeking a reliable method to optimize their ventilation performance without investing in complex mechanical systems. The 150 mm diameter and aluminum material are key features ensuring its durability and compatibility with standard ventilation pipes.
