Pressure Filter

altek International has been producing pumps, regulators and components for field sprayers since 1965. altek is well known to sprayer manufacturers around the world and has acquired an excellent reputation for its outstanding capacity for innovation, high quality standards and product durability. Its many years of experience and specialization in this ecologically and economically important niche has brought altek to the level of technological world leaders.

The efficient filtering of liquids is very important in the operation of the sprayer. altek has developed specific features to their pressure filters: The operators safety has been increased highly, since the filter element is removable to the top, during service. Undesirable contamination of chemicals to operator, environment and sprayer is avoided. The innovative concept of the pressure filter ensures, that the return flow from the regulator can be used for permanent filter rinsing. Extended working time of the filter between servicing is the result. Only the portion of liquid necessary for the boom spraying gets filtered. This increases the capacity of the filter.
