The Delfin DG EXP family of industrial vacuum cleaners is ideally suited for dust, solid and liquid materials, and ranges from 2,2 to 7,5 kW.
That’s according to its South African supplier Goscor Cleaning Equipment (GCE), which added that the the three-phase vacuum cleaners comprise three major components – the suction unit, filter unit and collection unit.
The suction unit is a side channel blower, with direct coupling between the motor and the impeller fan. It is designed without any transmission system, and is therefore silent, totally maintenance-free and suitable for continuous duty operations. “A vacuum gauge enables constant checking of the suction performance, and detecting of possible clogging of the filter,” said Peter Esterhuizen, National Sales Director at GCE.
The standard filter cleaning mechanism is operated by an external lever that shakes the filter vertically and enables the filter to be cleaned thoroughly and safely, maintaining constant suction performance and preventing any dispersion of dust in the environment.
“The large surface star filter, located inside the filter chamber, is made of polyester and provides high resistance against clogging and passage of fine dust. A vacuum gauge enables the operator to constantly check the state of the filter and detect possible clogging, warning the operator that the filter must be cleaned, dependent on the type and quantity of dust, additional filtration and cleaning options are available such as self-purging cartridge filters,” said Esterhuizen.
The third crucial part of the vacuum cleaner is the collection unit (100 litres). The vacuumed material is collected into a wheeled steel detachable container, which can be extracted for easy disposal and can be used with optional disposable bags, for safer and handier disposal.
“The vacuum is mounted on a sturdy steel chassis with pivoting wheels, one of which has brakes.”
