For many years Dustair Limited has been at the front of cyclone manufacturing across the UK, boasting a full range of cyclones from low through to medium up to high efficiency in either single or multiple form for various applications.
Commonly nowadays cyclones are used only as pre-filters before filtration equipment in order to reduce loadings, however on some applications cyclones may be suitable as a stand-alone unit. See selection guide for cyclone sizings.
Our full range of cyclones can be manufactured in various material utilising either mild, galvanised or stainless steel and can be provided either free standing or incorporating additional support steel work. Where necessary they can be provided with either additional after filtration or exhaust fans dependent upon the requirements on site.
Additional equipment for the efficient function of the cyclones including surge bins, dust collection facilities, rotary discharge valves and lagging of the equipment can be provided as and when required.
Where multiple banks of cyclones are required interconnecting ductwork would normally be included within our scope of supply, however if required the cyclones can be supplied individually for assembling into equipment on site. The range of cyclones covers a broad spectrum of efficiencies to match both particle size and the percentage removal required. Efficiency curves can be provided for most of the range together with sizing charts and layout drawings when required.
The three main sizes are based upon low (G type), medium (M type) and high (H type) efficiencies.

Preseparator cyclones on a tyre shredding plant prior to an open filter arrangement. The metal strands could be drawn off the magnetic separators attached to the fibres that were created from the internal cording in the tyres when shred. The filter system collected the fibres but the bulk of the heavier metal strands were to be removed by the cyclones. The cyclones were under positive pressure to allow the use of collection bags below the cyclones as rotary or other forms of valves would catch materials and block. A fire risk was mitigated by the filter plant being outside the building and exposed for rapid access should a fire occur.

Cyclones offer a high efficiency for larger particulate and therefore can sometimes be used as a standalone system as seen on this food dryer line where nut and grain husks were collected from the hot gas stream. Alternatively, they operate as part of a system, preseparating the heavier particles from the air stream in closed loop transfer systems or as part of the processes used to transfer materials around where constant pressure loss for consistent flow is important as on the blue unit here.
