Q. What are some of the applications of your vacuums in pharmaceutical plants?
Q. I am looking for a small portable vacuum cleaner to use in a solid dosage dispensing room. The vacuum would be used to clean up powder that has spilled on the floor, scales, table tops, etc. Can you recommend a product that might fit this application?
Q. What features should I look for when purchasing a vacuum that will be used in a cleanroom?
A. If your vacuum will be used in a cleanroom environment, a high efficiency particulate air (HEPA) or ultra low particulate air (ULPA) filter is an obvious must.The location of the filter is also critical. Because contamination standards in pharmaceutical industries are more stringent than other industries, HEPA/ULPA filters before and after the motor will help achieve optimal efficiency. Placed before the motor, an “upstream” filter protects the motor from the potentially harmful debris you are collecting. It will also help prolong the life of the motor and safeguard employees if maintenance is needed on a motor. A “downstream” filter, positioned after the motor, will eliminate the dust created by the motor’s commutator and carbon brushes from being released back into the environment through the exhaust stream.
Aside from superior filtration, simple, smooth construction is also important for a cleanroom vacuum as it prevents contamination by the vacuum itself and is easier to clean. Non-particle-generating material such as non-porous stainless steel is a preferred material in controlled environments, and hoses and attachments should also be smooth for fast, simple sanitization and validation.

Q. Tell me about your cleanroom filters.
A. Nilfisk Industrial Vacuums’s pharmaceutical and cleanroom vacuums can be equipped with either HEPA or ULPA filters.
Our HEPA filters retain 99.97% of all particles, down to and including 0.3 microns. Our ULPA filters retain 99.999% of all particles down to and including 0.12 microns.Industrial vacuums being used in critically controlled environments should also be equipped with both an “upstream” and “downstream” filter, as described above.
Q. What is the Safe-Pak™?
The self-contained Safe-Pak unit, offered on the Nilfisk IVT 1000CR, Nilfisk Industrial Vacuums 3156 and Nilfisk Industrial Vacuums 3306, safely isolates hazardous materials without contaminating your cleanroom vacuum or personnel. When full, the Safe-Pak unit is removed and discarded. No filters to change. No maintenance hassles. And unlike bag-in/bag-out systems, the rigid Safe-Pak container won’t tear. Simply slide out the unit and replace it with a new one. Nothing is easier or safer for handling potent compounds.
