The Bannatyne Dri-Flo Moisture Control System is a Silica gel-based drying system designed in conjunction with Willie McCallum that delivers longer playing time, and keeps drone reeds and drones dry. Silica gels are known to deliver 70% moisture absorption, which maximises the bagpipe’s performance output between drying. The system’s efficient air-flow to the drones makes striking-up and cutting-off straightforward with no decrease in drone volume or the need for drone valves. The Bannatyne Dri-Flo Moisture Control System is simple to install and remove, strong and lightweight compared to other systems, and easy to check when the Silica gels need to be dried out. The product includes Dri-Flo moisture control tubes and drone stock connections.
