Dust & fume extraction
SuperBlowers, said to be the world’s safest pulse cleaning dust filters, are on their way to New Zealand. The SuperBlower filter system developed by JKF Industri in Denmark has been continuously developed to provide the best possible solution in terms of safety, operating performance, energy efficiency and long term low cost ownership according to Geoff Ebdon, sales manager from NZ Duct&Flex, which is JKF’s New Zealand distributor. With hundreds sold worldwide, they will start to appear in our market from June this year. The first one is already in production in Denmark for a customer in Ashburton.
These filters are the first offering a new level of safety in the industry.
Dust is explosive and dust filters can (and sometimes do) explode, with devastating consequences for surrounding buildings and, more importantly, staff. The force of the explosion can hurl panels and small parts like nuts and bolts for hundreds of metres. Following some catastrophic explosions that resulted in many deaths and multiple injuries in the late 90’s, governments in Europe in 2002 and the USA in 2008 introduced laws which made explosive release membranes mandatory for all dust collectors. The membranes release the explosion in a controlled manner.
However, these membranes, whilst ensuring the bulk of the filter remains in one piece, still release a fireball which can project 50-100 metres from the filter causing damage, fires and injury to people.
JKF is a Scandinavian company, located in a part of the world famous for their obsession with safety. Swedish company Volvo have for decades led safety features in our motor vehicles and now has a target that from 2020 no one will die in their vehicles. JKF based in the small fiord village of Als in Denmark decided to try to achieve the same result with their dust filters; simpelthen
den sikrest it’s called in Danish – simply the safest. Ebdon says the SuperBlower range of filters arriving in New Zealand will take safety to a new level; they are the safest that can be bought. “Our NZ SuperBlowers will be fitted with explosive membranes that release the fireball blast just like other filters do, but this time vertically to the sky, not horizontally across the work site. In addition, there is no fireball as no f lame is released, just the shockwave.”
This feature is called VFV (vertical force venting) and is unique to JKF.
Unless personnel are above the roof of the filter at the time of the explosion (unlikely) they will not suffer injury from the release of the blast. There is little chance of damage to property or even the body or controls of the filter. If an incident occurs, usually it is a matter of just having to replace the socks and the membranes, and the site is back in operation.
All these extra safety features would normally cost extra as well, but JKF has decided to absorb the development and parts costs and fit this type of system to its SuperBlower and Jet filters at no extra cost. VFV will be standard on these units.
Ebdon summarised the new opportunity: “As suppliers, if we can offer a safer system at the same cost as the less-safe one why wouldn’t we? Our laws will change with effect from 1st April this year, making all directors, managers and supervisors personally responsible for safety at our respective levels. Why take the risk?” Further information is available by calling 0508 69 38 28 or visiting www.nzduct.co.nz
