Combination Sewer Cleaning Machine

The right tools can make all of the difference in how quickly and accurately you can get the job done. The Vac-Con Combination Machine is a proven method of “getting down and dirty” with the sewer cleaning process, allowing us to provide unmatched results.

How it Works

The Vac-Con Combination Machine gets its name because it is a combination vacuum and jetting machine, all in one truck. Jetting is a sewer cleaning process where high-pressure water is pushed through a dirty pipeline, flushing away the residue. Vacuuming, involves pulling sludge and other contaminates out and disposing of them in a sludge tank. There are pros and cons to both methods of cleaning, and utilizing both techniques at one time will give you the best results in the least amount of time possible.

Harnessing the Power of a Vacuum Truck

A vacuum truck is specially designed to pump excess liquid waste from catch basins, septic tanks, oil spills, and similar places. Commonly used for commercial as well as residential purposes, vacuum trucks not only carry out industrial waste material clean-up jobs but also perform waste removal jobs for municipalities which include street sweeping, sewer cleanup and much more. These vehicles are used for suctioning, transporting, and disposal of toxic and non-toxic materials and to pump anything from domestic septic tanks to contaminated soil.

What are Vacuum Trucks used for?

Suctioning of Materials – Vacuum trucks were mainly engineered for removing wet and dry, industrial waste. This vacuuming/suctioning is either high-velocity or low-velocity air suction used for removing solid, liquid, and frothy or sludge materials. Some other usage of vacuum trucks include removal of brine water, cleaning oil spills, sewers, catch basins, septic tanks and congested drainage systems.

Vacuum Trucks

Transporting Materials – The Environmental Protection Agency (EPA), US, encourages using vacuum trucks for transporting bio-solids due to their spill prevention and odor control abilities. These features curb the exposure of the hazards involved in these materials, for a healthier environment.

Disposal of Waste Materials – Some of the waste introduces potential health threats in the environment. Vacuum trucks are, thus, deployed for the disposal of such waste materials, thereby reducing environmental impacts.

With the increasing demand for vacuum trucks today, pre-owned and used vacuum trucks are the most popular choices than ever. Here are a few things you must consider before buying a vacuum truck on sale.

  • Before buying a used vacuum truck, it is important to analyze your budget. A proper budget will help you determine the kind of vacuum truck to fit your needs.
  • If you’re buying a new vacuum truck, you need to check for the warranty terms and support available. Also, it is important to get the proper paper work done.
  • If buying used vacuum trucks, check all the service records, logs for any major repairs, and examine them thoroughly before you purchase them. If they aren’t available, immediately rule out buying the vehicle.
  • Once you’ve identified the equipment that meets your requirement, inspect it yourself, or hire a mechanic who can inspect the machine, before accepting delivery.
  • Make sure that you or a trusted mechanic physically operates the machine, making sure that each component is in working condition. Also, evaluate the chassis, check if there is rust or damage.

Vac-Con Industrial Truck Advantages

Below please find a quick comparison of Vac-Con and other manufacturers. These few items are vital to the machine to make it the best in the industry.

Debris Body
Some manufacturers only offer a debris body with a 15 yard tank capacity. Vac-Con’s 16 yard debris body means fewer trips to dump the debris which means increased productivity and more fuel saving over the life of the machine. The debris tank is made of special Core-ten steel which is naturally resistant to corrosion and it is abrasive resistant.

Bag House
Most other manufacturers use dual bag houses which hold 68 filter bags total. They do this because they believe the only way to filter the air is to use more filters. Vac-Con uses only 26 filter bags total. This means the other bags are three times as expensive and will take three times as long to perform cleaning and maintenance compared to the Vac-Con. Vac-Con achieves proper air filtration through better design allowing the operator to run the system at a lower engine RPM and engineering of airflow through the machine. Vac-Con uses the Trademark Star Bag which has more cloth to air ratio than the standard filter bag. Additionally, the Star Bags can be washed and reused. They are also much less expensive than the typical cartridge type filters.

Hydraulic Oil
Most manufacturers use a 35 gallon hydraulic oil tank; Vac-Con uses a 50 gallon tank. As a result, Vac-Con can operate the chassis engine at lower RPM because more fluids are available to run the vacuum PD blower which equates to more fuel cost savings over the life of the unit. The hydraulic oil does not run the PD blower; it is used for operating the debris tank, rear door opener and locks, and boom only. The Vac-Con unit does have a hydraulic cooler which keeps oil temperature at the correct temperature for longer component life. Vac-Con hydraulic oil meets or exceeds ISO 68 oil standards for longer component life.

Vacuum Beaker Safety Relief
Other manufacturer’s use manual air operated vacuum relief; Vac-Con uses an automatic vacuum breaker. This ensures more safety on the job and prevents overfilling of the debris tank which can lead to debris “blow-by” getting into the vacuum pump which leads to failure. Vac-Con has one of the fastest Operating Vacuum Breakers in the industry; capable of breaking full vacuum in under two seconds ensuring operator safety.

Material Return System
The Vac-Con material return system was the first of its kind in the industry. The Vac-Con Industrial Material Returns system recovers the excess product from the filters and collects them in a hopper where they are evacuated back into the debris tank. This allows more time on the job and less time at the dump site. The operator is not exposed to the vacuumed product and does not have to manually clean or decontaminant the shoot tubes or collection boxes.

Debris Tank Vibrator
Some manufacturers do not offer any type of debris tank vibrator. Vac-Con offers both and electric and hydraulic vibrators. The hydraulic vibrator allows for a stronger vibration enabling the system to break loose heavier material when dumping the debris out of the body. The vibrator can also be used to loosen the material cake off of the Star bags so that it can be removed by the material return system allowing for longer run times on the job.

Debris Tank Construction
Most other manufacturers use mild steel for their debris tank construction whereas Vac-Con uses a Core-Ten steel tank which is much more durable steel that does not require a coating to protect it. It is much more abrasion and corrosion resistant to the mild steel. This means longer tank life on the Vac-Con.

Debris Tank Air Inlet
Vac-Con uses a final filter bag that protects the blower from unwanted carry over. Also the Vac-Con Inlet has twice the total square inches than any other manufactures allowing the Vac-Con to run at slower speeds.

What do all of these Vac Con advantages mean for you:

  • Vac-Con will load faster and has a larger debris body which means less travel time to empty the tank.
  • Fewer filter bags means lower cost and less maintenance time and cost.
  • ac-Con’s debris tank will last longer due to the Core-Ten steel which means a longer life expectancy for the truck.
  • Vac-Con Industrial loader has the state of the art Material Return System allowing for hands free cleaning of the machine and less decontaminate time between wet and dry jobs.

We hope that you can see by these comparisons that our system has all of the options and advantages that you need to provide a system for your clients that will get the job done quicker and save you more money over the life of the truck.

Industrial Vacuum Trucks

The word Industrial, as quoted from Webster Dictionary, simply means pertaining to, of the nature of, or resulting from Industry. In the Vacuum truck market, any truck that vacuums could be considered an Industrial unit. There are many different applications for the user of vacuum trucks in our market today, such as sewer sanitation line cleaning, storm drains, catch basins, containment pits and hydro –excavation. These types of vacuum trucks use a combination of vacuum and high pressure water at different flow rates to clean pipes and basins. Normally the material being vacuumed is damp or wet and sometimes a slurry material. This wet material conveys easily into the holding body or debris tank without much carry over into the atmosphere.

Industrial Vacuum Trucks

Not all material is wet and there is a need for the industry to have a machine that is capable of not only vacuuming wet material but also dry powder type materials, such as fly ash, cement powders and the like. These materials if vacuumed with a standard style vacuum truck would instantly make a cloud of dust into the atmosphere out of the exhaust of the blower. The common name for this type of vacuum truck is ”Industrial Vacuum Loader”. Continue reading

Who We Are – Vacuum Truck Leaders

Once again our service guru, Mike Selby, has outdone himself. He wants to let the world know who we are, so here it is.

Vac-Con was started in 1986 with two simple concepts; provide the customer with a quality machine at a lower price and make the machine the easiest to operate and maintain. 27 years later and with almost 7000 machines in the marketplace, these two key concepts still remain at the forefront of our mission.

The Vac-Con combination machine employs a two engine design that is engineered with the operator’s safety and comfort in mind. The deck mounted auxiliary engine drives the water system. Our water systems flow anywhere from 10 gallons per minute to 120 gallons per minute and require from 28 to 170 horsepower. Using the auxiliary engine to drive the water system allows the chassis engine to remain at idle during flushing, which reduces fuel usage, reduces heat that the operator is subjected to, reduces noise and, with the front operators station, enhances the overall safety of the operator by keeping them out of oncoming traffic. Currently Vac-Con offers two types of auxiliary engines, a 140 horsepower diesel engine or a 220 horsepower V-10 gasoline engine, and with the optional hydraulic pump installed, Continue reading

How to Unblock a Sewer with Sewer Jetting Trucks

The importance of employing appropriate sewer cleaning practices, whether in your home, factory or city cannot be undermined. A well maintained sewer goes a long way in improving health and cleanliness.
