Expanding on proven technology used in Absolent’s existing A.Dust range, the new AD filters have been designed utilising input from hundreds of real customer use cases to provide a truly modular, fully ’customer centric’ product line. Several pain points were identified and addressed during the 3-year project, as Absolent Air Care Group’s Chief Product Officer, Robert Wiktorén, elaborates, “As an existing manufacturer of dust collectors under our Absolent, Dustcheck and Diversitech brands, we knew there was a need in the market for a brand-new way of thinking about dust and fume extraction.
“Traditionally, dust collectors have been sized using generic data to select suitable filter type, filter area and air speeds between filter elements, and resultant footprints have been comparitively large. Noise levels are frequently high due to external compressed air cleaning systems and integral fans, and the units can be difficult to maintain. When filters need to be changed, even the best current designs require the filter retaining mechanism and moving parts to be in the ’dirty side’ of the unit, exposed to contamination. This is not a great environment for moving parts and requires a tool to reach the filter elements furthest away.
”Our ‘True Downflow” combines the verticality of the filter elements with a top to bottom air flow. This unique combination optimises the effect of gravity and ensures that the dust coming out of the filter elements during pulse jet cleaning are forced down to the disposal solution in the hopper.
“A baffle at the inlet evens out the airflow across the volume of the filter and makes sure we use each square meter to its maximum potential. Our True Downflow is the only solution that guarantees to eliminate any upflow or crossflow with the filter elements – traditionally leading to higher dust retainment and having to oversize the filtration surface.
“This enables us to offer ‘High Filtration Power Density’, continues Robert. “Using True Downflow means we can increase the filter speed, which results in the need for less filter media surface area. This enables us to package the solution in a far smaller footprint than other filter units on the market – this is what we mean by high filtration power density.
“Another unique aspect of the new range is the filter change clamping mechanism. The filter elements are linked together like a train – as the operator pulls the first element out, the next one is pulled to the front. No tool is needed, and engineers do not have to enter the dust filled unit.
“Locating the fan and cleaning unit inside the body of the filter decreases noise and we can reduce this even further if required by using additional noise attenuating measures. The standard units will be constructed from pre-treated Galfan steel which offers a high level of corrosion protection.
“The AD range uses modular construction. This means we are able to offer extremely competitive lead times, even for customised products.
”We have developed a dedicated configurator (CPQ) so with the help of our expert team, customers can build their own model to suit their specific requirements. The CPQ draws on an ever-increasing database of use cases to recommend the exact configuration based on inputs including contaminant type, required air volume, and system pressure.
“We are confident that the AD range will revolutionise the way end-users, OEMs and systems integrators think about dust and fume extraction.”
The first AD phase will include three models – the 0.5 which holds two deep pleat cartridges, 1.0 which includes four filters and the 1.5 which includes six deep pleat filter elements. Airflows will range from 3,000-9,000m³/hr.
The brand-new range of dust and fume collectors is being introduced in stages – phase one will see three models suitable for use in hot metals applications including welding, laser cutting, plasma cutting and non-ATEX abrasive metals such as grinding and linishing, available for customers throughout Europe and the UK. A prototype of the 0.5 will be on show at the Global Industries exhibition in Lyon next month, with start of production planned for April 2025.
Additional models for use in a wide range of other applications, including explosive dusts requiring ATEX certified equipment and higher air volumes (>65,000m3/hr) will follow later, along with alternative dust disposal options. Dust collectors suitable for pharmaceutical dust requiring safe change features will be added to the range during 2026.
