Mega Vac is a high-performance, large-capacity vacuum cleaner designed for purification and anti-static requirements. It features a 0.3 micron efficiency filter that filters dust and other particles, and can be optionally equipped with a 0.12 micron HEPA filter. The vacuum cleaner has a shielded design to prevent EMI/RFI noise interference and utilizes grounding of the motor and static dissipative materials to prevent static charge accumulation.
