The Tri-Vac Mud Monster is a specialised wet dry unit that is fitted with foam washable filter cartridges and has been given the extra power to be able to lift heavy wet slurry mixed with rocks, gravel, chips, sludge and metals. The foam filters allow water and sludge to be recovered with rock, gravel and chips and not get sucked into the high powered vacuum system. 
The latest company to experience the power of Vacteck's Tri Vac is Waterway Constructions, one of the largest specialist maritime construction contractors in Eastern Australia. The brief was to recover sludge, water, gravel and crushed rock from their drilling rig and the lift would be in excess of five metres. The Tri-VacMud Monster, with 17" of vacuum with a massive 7 metres water lift was the answer. With a huge water lift capability, massive vacuum power and an air flow to match, all that was left was to try it out. The system performed to cheers

|  | The drilling rig bores through a metre of rock and then needs to be lifted and the cutting tool and rig need to be cleaned of all the crushed rock, gravel and thick slurry. This is where Vacteck's Mud Monster takes over. |  | The 5 metre hose and 2 metre probe are then lowered into the cavity and the suck begins. |  | Mixing the crushed rock and gravel with a small trickle of water makes the evactuation run that much quicker. The Tri-Vac is attached to a 205 steel drum which fills in under 2 minutes. |  | A simple butterfly valve welded into the base of the drum allows the operator to cut-off the vacuum and then evacuate all the slurry from the drum into the sluice shute for disposal. |  | The Tri-vac Mud Monster attached to Waterways Constructions drill rig. |  | Vacteck's Tri-Vac means that the whole digging and drilling system is that much faster and efficient as the operators don't have to pull the drill core apart everytime they finish digging their metre drops, they just raise the rig and suck out all thecrushed rock and slurry. | 
| George, Waterways foreman on the Brisbane river reckons it saves them time and money and is a "bloody little ripper". |
