N 022 AN.18 diaphragm vacuum pump – The perfect combination of robustness, quietness and purity
The KNF N022AN.18 diaphragm vacuum pump has been designed to meet the growing demands of modern laboratories for cleanliness, reliability and performance. Thanks to its oil-free, dry running technology, this pump guarantees zero contamination during the transfer, compression or evacuation of gases and vapours. It is therefore an ideal solution for sensitive processes where gas integrity is paramount, particularly in the pharmaceutical, chemical and environmental sectors.
This model stands out for its ability to combine a compact, lightweight design with solid, consistent performance. Capable of delivering a flow rate of 15 litres per minute at atmospheric pressure, it achieves an ultimate vacuum of 100 mbar while maintaining a maximum operating pressure of 4 bar. This level of performance, combined with the recognised reliability of the KNF brand, makes it a major asset for installations requiring uninterrupted operation.
The aluminium pump head and resistant internal materials such as CR for the diaphragm and stainless steel for the valves offer excellent compatibility with slightly corrosive or aggressive gases. It is therefore perfectly suited to a wide range of applications without requiring regular maintenance, making it a particularly economical and durable piece of equipment in the long term.
Designed with simplicity and easy integration in mind, the N022AN.18 is equipped with fittings for 6 mm internal diameter tubes and operates with a standard 230 V / 50 Hz power supply. It is protected by an IP20 rating and incorporates a thermal switch for added safety. Its low energy consumption (100 W) and low noise level make it particularly attractive for working environments where discretion and efficiency are required.
Finally, KNF offers several accessories to enhance the pump's functionality, such as filters, pressure relief valves and fine control valves. These options allow the pump to be precisely adapted to the specific needs of each user, while maintaining a high level of safety and precision in operations.
