The roof drain is a reliable system for connecting downpipes and drains on flat roofs, gutters and industrial buildings. 

It is ideal for use with a variety of materials, roof accessories, including APP, SBS-modified bituminous membranes and liquid bituminous coatings. 

The funnel has been designed with maximum performance optimization in mind, allowing it to increase its drainage capacity by up to 45% compared to standard drains with a diameter of 170 mm and a depth of 30 mm. 

The total length of the funnel is 330 mm, which allows it to be used with thicker bases and eliminates the need for intermediate connections.

The insertion into the downpipe nozzle provides a constant and continuous flow without loss of performance.

The modified PVC material of which the funnel is made is highly resistant to UV rays, ozone and other atmospheric and chemical agents. 

It can be used over a wide temperature range due to its extreme flexibility at low temperatures. 

The physical and mechanical properties of the material ensure maximum performance over the entire service life. 

The drain includes a truncated body with various diameters, which is firmly attached to a ribbed flange.

All drain elements are made of the same materials to ensure better adhesion of the membrane. 

The stem portion of the funnel has two or more strategically placed outward facing O-rings that provide a perfect seal when impacted on the drain pipe. 

The sealing rings are compressed when inserted into the downpipe and guarantee an optimal seal for any type of pipe, preventing water vapor or water from entering the roof system. 

This is especially important when using insulation, as improper sealing can damage the insulation itself, which is one of the main problems with roof waterproofing.

The roof drainage funnel is a reliable solution for efficient drainage of water from flat roofs and other objects.

Thanks to optimized performance and increased drainage capacity, it provides reliable protection against water accumulation and damage to the roof structure. 

The modified pvc from which the funnel is made has a long service life and high resistance to various weather conditions and chemicals. 

This ensures the reliability and stability of the funnel during the entire period of operation.

Therefore, a drainage roof funnel is one of the most reliable systems for connecting downpipes and drains on flat roofs, gutters and industrial buildings. 

It has high efficiency and improved drainage capacity, making it the ideal choice for reliable water drainage from the roof.

A feature of improved PVC is its high resistance to ultraviolet rays, ozone and other atmospheric and chemical substances.

As a result, the funnel can be used over a wide temperature range, as it is highly flexible even at low temperatures. 

The physical and mechanical properties of the material ensure optimum performance over the entire service life.
