PTFE Filter (Primary Filter)

When dealing with sticky and sharp debris like glass fiber dust, a higher level of safety is required. In fact, the most popular industrial vacuum filters like the standard Polyester Star Filter, may not be strong enough to prevent cuts or clogging. The PTFE (Polytetrafluoroethylene) coating does the job. In fact, the clogging debris don't attach to the fabrtic, smoothly falling into the collection unit.
