The Ross Canister system includes both canisters, and hoses. The basic concept of the canister system, is that the air must pass through the canister filled with drying granules prior to reaching the reeds.
This canister system, combined with the highly breathable bag, offers pipers the best available means of controlling moisture, which means much greater stability of tone and longevity of reeds. The type of granules used in the Ross Canister system is unquestionably the most efficient moisture absorbing material that can used over and over indefinitely, hence the best method of keeping wet reeds and drones at bay. Drying the granules is achieved by placing them in a microwave for a few minutes. A second canister is provided with each complete setup, which provides pipers with a reserve canister for competition days, or long play sessions if needed.
Important Product Note: All bagpipe water traps can develop mold and fungi with regular use if not cleaned and disinfected properly. This can lead to chronic inflammatory lung disease. Please take careful precautions to ensure your water trap is cleaned and disinfected on a regular basis to prevent mold and fungi from developing.
