Description

LABOPORT N 86 KT.18 mini diaphragm vacuum pump – A compact and robust vacuum solution for demanding environments

The LABOPORT N 86 KT.18 mini diaphragm vacuum pump is the perfect combination of compactness, performance and chemical resistance. Designed by German brand KNF, a recognised specialist in oil-free pumping technology, this pump is a must-have for laboratories that handle corrosive or volatile gases. With its minimal footprint, it offers remarkable efficiency while ensuring clean and environmentally friendly operation.

This model is completely oil-free, guaranteeing contamination-free gas transfer during both the vacuum and compression phases. This makes it an essential piece of equipment in laboratories where process purity is paramount, particularly in analytical chemistry, pharmaceutical environments or during sensitive handling operations. Thanks to its PTFE-coated diaphragm and FFPM valves, it offers excellent resistance to aggressive chemicals, ensuring consistent longevity and reliability.

Equipped with a 60 W motor with thermal protection, the LABOPORT N 86 KT.18 operates stably, quietly and continuously. It can achieve a vacuum limit of 160 mbar and withstand a working pressure of up to 2.5 bar, while maintaining a constant flow rate of 5.5 litres per minute. Its lightweight design (1.9 kg) and compact dimensions allow it to be easily integrated into any workstation or automated system.

This model also stands out for its eco-friendly approach. Requiring no oil or intensive maintenance, it reduces its environmental footprint while simplifying daily maintenance. Its durable design and high-quality materials make it a great investment for organisations looking for long-term reliability and performance.

The LABOPORT N 86 KT.18 is complemented by a range of practical accessories such as silencers, fine control valves with pressure gauges and pipe adapters for different diameters. These components allow quick adaptation to the specific requirements of each application. Whether for evacuating a volume of gas or maintaining a precise pressure in a closed system, this pump delivers efficiency and discretion.
