Ruwac USA offers the HEC-XLT-EX pre-separation system, which will prevent fine dust from prematurely clogging your vacuum cleaner filter. The pre-separation system features Ruwac's 12” high-efficiency cyclone and collects up to 97% of fines prior to reaching the filter, reducing downtime and filter replacements in the process. A lifting assembly mechanically raises the HEC unit from a drum collector while the drum tips for fast, easy emptying, according to the company. The system also includes an equalizer kit that allows plastic bags to be inserted inside the drum for hassle-free clean-ups.
