ESD/anti-static vacuums and vacuum accessories remove dust and debris from clean rooms and electronic devices. They do not allow damaging ESD (electrostatic discharge) build up. Dual-function vacuums, also called blow vacs, use a blower function and HEPA filtration system to maximize efficiency. HEPA filters can filter out particles as small as 0.3 microns and do not redistribute particles in the air. ESD/anti-static vacuum accessories include nozzle attachments, hoses, filters and straps.
