The Pearson AirStream Cluster Flushing system flushes out the cluster after every cow. High amounts of Staph Aureus remaining in the liner can cause mastitis to spread throughout the herd after the milking of an infected cow. The AirStream Cluster Flushing system used with peracetic acid and injected with compressed air gives maximum washing and drying routine. The Pearson AirStream Cluster Flushing system can be fit into any parlour without alteration for the existing equipment.
