This system can be configured with anti-static properties that make it inherently safe in explosive dust environments. Read about it here. 

The Reverse air blast filter cleaning has now opened up all Vacteck products to applications like powders, cement dusts, pharmaceutical powders, plastics and all types of fine industrial waste that needs efficient filter operation and cleaning without allowing the dust and waste exposure to the operator or the outside of the capture vessel.

• The reverse air blast filter cleaning works by re-directing a pre-determined amount of air through finely machined blast holes that are spaced along the internal blast tube.  The operator simply shuts off the vacuum once the waste has been recovered and then cleans the filters with a quick burst of fresh compressed air, knocking the built up layer cake off the filter ridges and returning the filter to pre recovery condition, without any dust or powder escaping the vacuum tank.

• The control handles are standard ball valve type. Sturdy and strong, positioned for ease of use. The reverse air blast has red air blast tubes that make it easy to identify the vacuum knob and the filter clean knob.

• The construction of the high powered drum vac with reverse air blast filter cleaning is incredibly strong, perfect for an industrial setting where tools are damaged easily. The vacuum intake is positioned and directed to create a cyclonic entry of the powder waste which slows it down and forces it away from the filters.
  

• The construction of the vacuum air supply and the reverse air blast has been designed to allow easy visual inspection of air supply lines to help keep the integrity of the vacuum system intact.
  

• The top shot of the air blast handle and the vacuum handle, showing the 1/2" air supply line is use for the heavy duty 3517 Tri-Vac. This system has huge power to lift liquids and dry waste. Now with the reverse air blast filter cleaning the recovery of fine powders and dust makes this machine ideal for this kind of work.

• The development of the reverse filter cleaning means that an operator can work effectively and efficiently with heavy and fine powders including cement dust, agricultural powders, plastics powders, grain dust and most kinds of fine, light weight waste. No longer will the vacuum be reduced by the filters clogging up and the operator needing to remove the lid and blow down the filters. It is all done quietly, cleanly, safely and effectively under the lid. No mess. Just a quick turn of the handle and the filters are cleaned.

• Factory cleaning with the high powered Tri-Vac fitted with reverse air blast filter cleaning is now a whole lot easier, quicker, safer and effective. Powders and dust particles can be recovered and removed from the work place in a matter of moments. Don't worry about dust or powder effecting the vacuum system. It can't. Nothing goes through the vacuum itself. Unlike an electric vacuum that can cease when dust or powder enters the motor, an air powered vacuum has no moving parts.

• Powders whether heavy or light are picked up with ease with the huge power of the 3517 Tr-Vac.

• The workplace can be kept clean with a minimum of effort.

• The closest the operator comes to the dust and powders is when he removes the lid and there in the bottom of the drum is the waste.
