Why Replace Your Anesthesia Machine Bellows
The bellows is the flexible gas reservoir inside the ventilator bellows canister. During mechanically ventilated anesthesia it compresses and expands with each breath, so its folds wear with use and cleaning cycles. A cracked, stiff or perforated bellows can cause leak test failures, inaccurate tidal volume delivery and ventilator alarms. Keeping a replacement Mindray WATO bellows on hand helps biomedical teams restore the breathing system quickly and keep the machine in service.
- Restores leak-test performance a fresh, pliable fold bellows seals correctly within the bellows housing.
- Smooth, even travel eight uniform layer folds expand and collapse consistently for stable ventilation.
- Latex-free construction suitable for patients and staff with latex sensitivity.
- Reduces downtime a direct-fit spare that suits planned maintenance and urgent repairs.
