Vac System Industries: anti-dirt pre-filters
The company says its new anti-dirt pre-filters feature a new material from which most dirt just slides off. They are designed for the company’s Super Collector 300 vfd and 6000 portable vacuum collection systems. Since most of the collected dirt and debris and other contaminates slide off of the pre-filters, the pre-filters take much longer to become covered with dirt, says the company. This means its Super Collector systems can maintain higher levels of negative pressure in the ductwork for even a longer period of time.
