Before vacuum excavation became available in the 1950s, hydro excavators and manual methods were the norms. While the technology has existed for several decades, it has taken time for air vacuum excavators to become globally accessible. Vacuum excavation is now as refined and efficient as ever before, and has a wide range of applications. It is the preferred excavation method for engineering, construction, and utility projects. VAC-EX is a UK manufacturer of compact, towable vacuum excavators and safe excavating equipment. Everything we do is to allow safe excavation around live services and utilities. VAC-EX has drawn on its years of experience with the larger vacuum excavators to provide the industry with the AIR-VAC, the first ever machine that solves the problem of safe digging, in restricted access areas.

However, a cordless vacuum cleaner may not be the best choice if you have lots of carpet or a large area to clean. Corded upright and cylinder vacuums aren’t limited by battery life, and in most instances they have more powerful suction. Petrova also recommends looking for a vacuum with a HEPA filter, “as they provide the best method of filtration and traps even particles too small to see with naked eye.”Air-Vac’s vacuum pumps are often used for vacuum evacuation, transfer, and material handling. Besides vacuum products and components, they manufacture rework, soldering and assembly modules. They also produce highly automated precision equipment for businesses that need on the spot and unparalleled accuracy. o A small footprint means the vacuum excavator can be operated in a third less space than a mini-digger. o P.E. pipe extension tube reduces utility damage by 60% compared to other methods of excavation, while providing insulation to vehicles and workers while working in high-risk areas. Our range of air vacuums are AD36 25L bin 206CFM, AD46/60 60Lbin 235CFM, AD46/100 100L bin 234CFM and the AD56 100L bin and 471 CFM ,are all capable of removing oil, sludge, swarf, food, slag, sand, turnings etc. The AD56 is available with twin venturi for extra power. A choice of comprehensive 70mm /50mm or 40mm accessory kits is available. Airflow measures the amount of air pulled through the hose during operation. It’s often considered a better measure of a vacuum cleaner’s performance than waterlift, because it takes into account the resistance of the filter, bag and any other impedances to airflow.

Air-Vac also offers Stainless Steel designs for abrasive material and high temperature applications and can do custom designs for your requirements. Air-Vac and AOP Technologies Compressed air-powered vacuums offer a number of significant advantages. The main advantages are that they have no electric motor, or any moving parts which when placed in an industrial environment can clog and wear out.. Therefore, they are ideal in heavy duty-cycle (on-off-on-off) applications which shorten the life of electric vacs. Because there is no electric motor, sparking at the brushes is eliminated and require no high voltage trailing cables, an important feature for wet and/or hazardous environments. The unit working from plant air supply is often more readily available than electric power in many in-plant locations. Civil engineering and infrastructure – used in building roads and large-scale construction projects.According to professional cleaner Katerina Petrova of the Happy House Cleaning Company, that largely depends on the area you have to clean, as well as your budget. In our tests it was faster and less ‘dithery’ than other robot vacs, forming a confident map of its surroundings. Trundling around quietly (it’s no noisier than a desk fan), it was impressive on hard floors and while did leave some fine dirt behind on carpets on the first pass, it got it up on a targeted clean. Air-Vac produces a wide range of vacuum pumps for different applications. With two Venturi designs and six concepts, Air-Vac provides the flexibility of design to meet your specific vacuum needs. Waterlift measures the suction at the foot: if the bottom of the tube was placed in water, this measures how far water would rise up the tube before gravity cancelled out the power of the motor. A vacuum with higher waterlift will be good for deep carpet cleaning. It’s also called sealed suction. Compact machines – our machines are smaller than others, and effortlessly traverse tough terrain and tight spaces.
