The Shark 9000-II complete service vacuum kits (120V) provide an excellent portable vacuum solution for maintenance personnel and field technicians. All Shark 9000 models use a pleated micro fine paper especially designed to pick up sub-micron particles. LaserVac portable industrial vacuum cleaners use a unique by-pass system that cleans the contaminated air being brought in by the vacuum in a high efficiency filtration module, separate from the motor, resulting in a safer and longer-lasting vacuum. The high efficiency (98% efficiency) filtration module holds up to 5 lbs. of toner or 20 lbs. of developer, and allows up to five shakeouts for reuses. The Shark 9000 vacuum weighs approximately 11.5 lbs.
