Along the North wall, a small squirrel cage fan is installed to inflate the double layer polyethylene film on all eight roof segments. The air from the fan is delivered to a PVC pipe that distributes the air to each roof segment through flexible hoses. The air pressure provided by the fan is a little less than 3/4" water gauge.
