Shoe repair technology – Extraction
Integrated extraction system
- The principle of high pressure and a cotton filter is at work here
- Filter material: Specially coated cotton: Flame retardant and smoothed to prevent dust adhesion and for faster dust collection
- The filter is changed from the rear
- Dust separation level up to 90%
For Caravelle machines additionally:
- Fine dust filter mat with complete rear wall cover for even cleaner air and further sound insulation
- Dust separation level up to 99%
As work shops vary in size, HARDO offers a choice of various dust extraction devices. Filter units can be placed next to the machine, next door or in the basement. A weather-proof version to be installed outdoors is also available. All HARDO filter units allow you to choose between different systems and rely on fully automatic filter dedusting.
Flow-optimised HARDO filter cabinet with 40% greater extraction capacity for maximum dust reduction in your workshop – the new benchmark in extraction technology.
Top priority was given to a significant increase in extraction capa-city combined with low power requirements and reduced noise in HARDO’s new filter cabinet series.
The filter cabinet series needed to be re-designed and built from scratch to meet such strict requirements. Our development work has produced the HARDO AERO+. Thanks to its flow-optimised structure, it has achieved an increase in extraction capacity of more than 40% compared to its predecessor, yet its energy requirements have remained the same at 3 kW. The HARDO AERO+ is also whisper-quiet in its operation thanks to efficiently soothed air flow within the filter cabinet and acoustic insulation in the exhauster compartment.
Permanently strong extraction capacity
One of the key objectives in developing the filter cabinet was to achieve persistently high suction power without filter elements becoming clogged too quickly. Our solution was to soothe the dust-laden incoming air flow in two stages. This allows all coarse particles to be pre-separated,
so that only a small proportion of the aspirated dust reaches the filter elements. This brings several advantages: reduction in stress on the filter, an increase in the filter service life and longer cleaning intervals.
The HARDO AERO+ also features software-controlled jet pulse dedusting with optimum air flow guidance to ensure the filter is kept extremely clean. This ensures the filter cake is blasted across the whole filter surface, guaranteeing a long-lasting, strong suction capacity!
