These cleanroom vacuum cleaners are equipped with an electronic filter suppresser which reduces electromagnetic interference (EMI), both radiated and conducted, below class B limits for digital apparatus as established by the FCC and ISO.  It also provides shielding against RFI (Radio Frequency Interference).  The electronic filter is wired in line with the motor.  If the electronic filter should fail, power to the motor will automatically be cut-off.  These vacuum cleaners will not disrupt computers, radio and video monitors and other sensitive electronic equipment.

The vacuum cleaner is designed to be grounded during use.  Any static electricity that is produced while vacuuming is dissipated through the conductive hose, through the vacuum cleaner and it is discharged to the ground.  A ground continuity tester is included with every vacuum cleaner to verify ground continuity before use.  The ESD safe vacuum cleaners eliminate static electricity and static charge buildup and they protect sensitive elctronic equipment.
