Why does the collector need to be fully welded and not bolted?
Apart from being a superior form of structural integrity from a manufacturing point of view, bolted dust collectors are more likely to have long term issues. Depending on the metals, can cause oxidisation and rust. The Dust Collector could also become a projectile in the event of an explosion. Another process to add to the annual servicing which will add the cost and decrease the ROI of the collector.
How come there is so many different types of filters on the market and which one is best for my business?
Because various products/ dusts have different properties- hygroscopic, acidic or alkaline, particle size, etc, different filter media may be required. Dust is often measured in microns (μm) (size of the dust particle).
Why does my duct continue to get blocked?
The most reason why ducting in a dust collector will get blocked is because there is not enough velocity (m/s) of air moving through the duct. This is a good indicator that the ducting was not designed properly or modifications after installation are having a detrimental effect.
How long will my dust collector last for?
A dust collector from DCS with proper maintenance and care will last excess of 20 years. Filter will need to be changed in that time, depending on the dust characteristics.
Does my dust collector need maintenance?
Yes, All mechanical equipment needs servicing. Just like your car, a dust collector has mechanical/moving parts and requires servicing. Just like your car a regular servicing plan can avoid larger and expensive problems.
Do you manufacture your collectors in Australia?
Yes, All DCS dust collectors are manufactured at our facility in Narangba, Brisbane. We also source our steel and components from local business. We believe that the best way is the Australian way for the future of our kids.
Is PVC ducting ok to use?
No, PVC is a very large safety issue within the dust collection industry. PVC conduit is a polymer made from Poly (vinyl chloride) which can be a considered a plastic (depending on who you ask). So when you have large quantities of air moving past this material it builds up static electricity. If this is not earthed and allowed to build up, the static electricity can cause a spark in the ducting. This is especially important to industries that are working with combustible materials such as timber or paper processing mills. If you add a spark to a combustible material and high volumes of oxygen, then I am sure we can all imagine what happens next
What the difference is between and shaker and pulse dust collector.
The main difference is simple. A shaker dust collector shakes the dust off the filters and a pulse dust collector uses high pressure air to blow the dust out of the filters. Shaker type collectors often struggle with removing fine dust from filters causing the filters to continue to get blocked, because they do not push the dust out of the pores of the filter and shaking can only be done with the collector not working.
Is dust combustible and what can be done to mitigate the risks?
Yes dust can be combustible. Dust from cellulose, grain, nuts, timber, flour, carbon based dust (coal, minerals), Sugar, Lucerne, nuts, and many, many more. Damage from explosions can be minimized by a robust welded casing with explosion relief panels. For any flammable materials DCS limit the chance of a static spark and subsequent chance of explosion with the use of anti-static filtration media.
What are the signs of a cheap and poorly manufactured dust collector?
Signs to look for when purchasing a dust collector are, the quality of the build,the thickness of the panels and if they are bolted or welded, corrosion protection, control valves and solenoid valves. Also has the dust collector been designed for a particular project or is it a ‘shelf product’ that will do the job? Is the collector Australian Made to Australian standards and conditions?
Why do I need an explosion vent? Other collectors don’t have them.
Explosion vents are important in the unfortunate occasion of an explosion. These explosion vents will reduce the overall impact and can direct to the blast away from key infrastructure and personal. Explosion vents are necessary as a risk mitigation and safety.
What are the advantages of extended surface filters over bags?
Extended surface filters, as the name implies have 3-4 times the filter area of an equivalent sized bag. This means that the dust collector size can be reduced, and reduces the size and cost for the dust collector.
Can I use bags to replace pleated filters?
Not if you want your system to work properly. Pleated filters have a much larger surface area and are designed to have a certain amount of air moving through the filters (cloth ratio). By changing from pleated to bag filters this cloth ratio is dramatically increased, and at best will result in very short bag life, or blind very quickly.
Why do you install most collectors outside?
Because many dusts have the potential to explode under certain conditions, it is preferable to install the collector outside the work space to create a safer working environment.
Why do DCS fit a clear inspection window?
A clear inspection port allows you to see at a glance if there is a problem due to (a) the bin not being emptied, (b) leaking rotary valve if fitted, and (c)to avoid having to open the collector to be sure that no large foreign objects have been drawn into the collector. (We have pulled caps, towels, newspapers and long slivers of laminate and timber out from hoppers)
Why are the access covers pivoted in the middle?
The only sure way to seal a door/ access cover is to pivot it so that pressure on the seal is applied evenly all around. The same principle is used for water tight doors in ships for the same reason. It takes a bit more effort, but the result is worth it.
