iQ Power Tools introduces the iQ426 HEPA Dust Extraction Vacuum. Engineered to meet OSHA’s silica dust requirements for working in construction applications, what makes the IQ 426 HEPA unique is the airflow tuned cyclone technology. Less than 1% of the dust reaches the filter, which means vacuum maintains optimum performance.
The IQ 426 HEPA has 4 stages of filtration: (1) large cyclone captures larger particle sizes; (2) small cyclones captures medium to small-sized particles; (3) filtration system captures the tiniest particles; and (4) HEPA. The first two stages utilize cyclonic filtration, which pull and capture different sized particles from the air stream, keeping them from reaching the final two stages.
