Air system double membrane cover

To keep a stable pressure between the membranes we have 3 critical components: blowers, an air supply system, and an air relief system. For every double membrane cover, we calculate and design the perfect fit for the given situation.

Blowers

To create steady pressure between the membranes, our blowers ensure that sufficient air is being blown between the two membranes at all times! We have two standard types of blowers that we use currently: the FRv110 and the FRv110+. With these two options, most of the systems will be 100% equipped for the needed gas production and gas withdrawal. On request, we can calculate the amount of air that the blower will be able to get into the roof and at what pressure. While the FRv075 is no longer used for new installations, it is still a viable option as a replacement for older installations. Upon request we can help you determine which type of blower is best suited for your project.

Air supply system

To further stabilize the air system, we use a very  high-quality air supply system. It is mainly made from HDPE to provide a long-lasting system and is meant to get the pressure and flow from the blower between the membranes. When choosing the system, it is important that the diameter is taken into consideration to make sure the blower is able to deliver as much pressure and flow into the roof as is needed on the project. As a standard we use diameters of 110 mm or 160 mm for the air supply system. Upon request we can deliver in any required diameter.

Air relief system

When the blower and the air supply system are working correctly, the pressure between the membranes should never drop below the desired air pressure. To prevent the pressure in the roof from becoming too high, a well-calculated air relief system is extremely important.  We will set the air relief system at the desired air pressure. The valves on the systems will open when this pressure is reached and will make sure that optimal pressure and/or flow is released into the air. Both 110 mm diameter and 160 mm diameter air relief systems are always on stock in our warehouse!
