Aeration & Mixing is the exclusively authorised EU distributor of Nikuni VDF robust stainless steel hydrocyclones, which provide the proven element-free method of removing metallic contamination in the honing, machining, cutting and forming coolants used in machine tools. Nikuni VDF hydrocyclones are available in a range of 7 useful sizes from 10 lpm to 300 lpm plus a 1,000 lpm unit.

Nikuni VDF hydrocyclones will typically remove as much as 95% of aluminium particles at 10μm and above in one pass. The product can provide a number of operational benefits that include increased capital equipment life, the elimination of blocked filter element replacement, reduced machining costs and can contribute to a better surface finish - often in a reduced cycle time.

One major benefit of the Nikuni VDF hydrocyclone is that it can act as either a standalone product or a component for integration within an existing system. This simple product, which uses centrifugal force to separate metallic and other contaminants from fluids, is well established across the Far East and the USA and is currently experiencing a rise in demand in Europe. It is becoming of great interest to many companies involved in CNC machining, precision grinding and honing who wish to reduce the cost of replacement filter media, and the expense of environmentally acceptable disposal of contaminated elements, often a significant element of their operational costs.

Nikuni’s VDF hydrocyclones ensure coolants fed to machine tools are cleaner whilst avoiding the frustrations surrounding downtime from blocked filter elements. It is normal for a Nikuni VDF to achieve payback for its installation in a short space of time, because the need for conventional filter maintenance is removed along with the costs of repeated filter element replacement and disposal. Furthermore, the optimisation of performance and improvements in productivity are within the reach of all sizes of organisations from multi-nationals to single unit SME installations.

As a standalone facility, the Nikuni VDF hydrocyclone can be supplied with or without a pump and with manual or automated air operated valving and a sludge pod for consolidating and collecting separated contaminants. One additional advantage of fitting a sludge pod to a VDF hydrocyclone, is the volume of coolant in circulation in the cleaning circuit is greatly reduced, thereby saving energy and reducing the volume of waste fluid collected.

Nikuni Co. have just launched a new type of sludge pod, the 2-litre capacity ‘Drum Pod’ intended for applications where automated collection and discharge of separated material is not required. A simple quick-release catch allows users to remove the Drum Pod and dump the separated material into a large dedicated container.

Aeration & Mixing welcomes enquiries from any industry or process, large enterprises or SME businesses. The Nikuni VDF hydrocyclone is also often applied to the separation of fine particles of non-metallic wastes. Recent new particle separation applications include diamond dust, carbon particles, metal particles in plastic waste streams, iron particles from clays, metallic and carbon particles from oils, sands and silts, ceramic particles from coolants and nickel powder from cooling water, all proving effective separation down to 4um particles and in many cases smaller. Aeration & Mixing hold good stocks of the Nikuni VDF units in the UK and can supply all except the 1,000 lpm model at short notice.

Aeration & Mixing offer prospective users of the Nikuni VDF hydrocyclone systems the option to hire a unit for a trial period, to enable a new customer to prove the value of element-free separation in their own factory or works environment. In addition, A&M’s analytical services are available to retrospectively analyse separated particles, to show aspects of the separation performance.
