Independent tests with water/peracetic acid solution wash have shown:
"The performed swab test has demonstrated 100% bacteria reduction in the liner after 'AirWash' flushing cycle."

Independent tests with cold water wash have shown:
“With the ‘Airwash’ system an average reduction by 93% in cell count in the teat cup was accomplished, with especially high cell counts a reduction of over 99% appearing to be possible.”

“Flushing of liners with the Airwash system between milking of each cow reduced total bacterial counts of liners with about 90%. Flushing reduced Staphylococcus aureus counts after milking infected cows with about 75%.”
(Source: Danish Institute of Animal Science)
“The important point is that the flush reduced great numbers of mastitis causing organisms to just trace amounts of the organisms in the inflation. Therefore, a reduction of the number of organisms causing the infection will decrease the incidence of mastitis in the herd.”

Greenoak AirWash won "Best New Product" award in 2008. The Scottish Farmer magazine says: "THE FIRST championship' at AgriScot, this week, went to a new innovation which should help dairy farmers cut down on mastitis spread between cows in the parlour."

Greenoak AirWash is a cluster flushing system - a powerful tool in mastitis cross-contamination prevention. The system provides a hygienic liner for every milked cow by automatically sanitizing the inner surfaces of each milking liner after cluster removal.
Results of the study conducted in the Netherlands by the Dutch Animal Health Control have shown that the remains of Staphylococcus Aureus bacteria are present in theliner for at least the following 6 milkings after milking the infected cow.
Mastitis cows dramatically reduce the milk production and therefore a considerable loss of income. Subsequent problems with the animal health and fertility contribute to increased expenses. High level of bulk tank somatic cell count is resulting in lower payment from the dairy processor for the collected milk.
Unique Greenoak AirWash cluster flushing system tackles all the above problems in a simple and efficient way. It reduces the risk of "cow-to-cow" cross infection to an absolute minimum with no change in your milking routine.
The system totally flushes out the remains of milk and bacteria by using mains or bore hole water with sanitizing chemical and filtered compressed air after milking each cow.
Lab tests have proven that the AirWash system reduces the number of pathogenic bacteria by 100%! Our customers confirm great results which AirWash helps achieving.

Concept of operation
The system is simple in design, easy to fit and requires minimum maintenance. The water used for
sanitizing the clusters is standard or bore hole water filtered and fed into a 10 liter header tank.
The system incorporates Dosatron - an automatic chemical dosing unit which the water is pumped
through and the correct concentration of chemical is mixed in. Most installed systems have
incorportated peracetic acid. Its use results in 100% of pathogenic bacteria flushed from the liner.
Wash solution and compressed air is intermittently injected into the liners 30 seconds (delay could be set to a different value, if required) after take-off of the cluster. The injection is carried out via special design injectors. Injectors can be fitted to any type of milking liners as they come in 3 different sizes of 8, 10 or 12 mm. When the system is fitted there is no need to replace existing milking clusters or purchase any special liners. Each AirWash injector has a non-return valve,
thus the AirWash system does not affect the milking vacuum level and stability.
AirWash system can be integrated into any brand/type of the milking machine and configured for fully automatic operation in two different ways:
1. For double side milking parourls the flushing cycle starts for all the milking clusters on one side at the same time once the exit gate opens. The system starts off the exit gate switch signal.
2. For swing over milking parlours the flushing cycle starts after milking finishes at each individual
point. The AirWash control box senses "end of milking" signal from Automatic Cluster Removal
(ACR) system. The AirWash control box can be connected to any existing ACR system.
Manual start push button option is also available.
The AirWash flushing cycle timings and water usage can be easily programmed to suit
individual needs of the farmer. As a recommended standard the system is set to perform five wash
solution flushes each followed by compressed air blast. The total cycle lasts only 20-30 seconds
and requires only 400-500 ml of water.
