Filter: a porous article or mass (as of paper or sand) through which a gas or liquid is passed to separate out matter in suspension.  Something that has the effect of a filter (as by holding back or separating out elements or by modifying the appearance of something such as an Air-Cleaning BlowerTM (ACB).

 

Filtration: The process of filtering

By these defining filter terms, ACB’s are a type of filter since they remove particles suspended in air and other gases.  However, they function differently and offer many advantages over media-based filters because they both 1) use no filter media and 2) move (blow) air.
These differences enable the user of an ACB to eliminate all filter media and thereby the labor, energy losses, clogging and other costs associated with media.  The units also eliminate the need for a fan to blow the air through the filter media, which generally makes the Air-Cleaning BlowerTM more compact and easier and less expensive to install, operate and maintain.

 

Installation: We have also designed ACBs to be easy to install, any many cases much like a kitchen fan.  First, make a hole in the wall the diameter of the discharge hole of the ACB (if desired, add a duct inside the wall and/or extending from the wall).  Then, fasten the ACB’s integral mounting plate to the wall with bolts and connect the wiring.  On the far side of the wall from the ACB, mount whatever kind of discharge grille or duct that you want.  That’s it!

 

Predictability: Without the clogging that always occurs in filter media, air-cleaning blowers will provide constant performance that can be relied on.  Predictability makes the systems easier to design and size.

 

Constant airflow: Constant airflow is maintained due to the lack of a filter media or canister restricting airflow, particularly as it fills with trapped debris and clogs.

 

Constant cost of electricity:  The fan motor uses a constant amount of electricity since it never needs to push through a dirty filter or canister.

 

Configurations: We configure different models for different purposes.  As an option, ACB’s can also be adapted to collect the particles separated out if they have a value, such as a dusty product that escapes from a conveyor or bag filler.

 

Cooling and air changes: These units push air from outside into the space being conditioned.

 

Purging and pressurization: These units work similarly to those for cooling and air changes, but they have additional controls to enable them to maintain a steady flow of air to provide a steady air pressure in the conditioned space and/or to greatly increase the flow temporarily into the space to purge it of unwanted gases or other contaminants.

 

Ventilation:  These units push clean air into a space to replace/change the air inside.

 

Exhaust:  These units pull air out of a space to replace/change the air inside a space.  Generally, they are installed to exhaust air out of a space without the dirt inside escaping into the surrounding atmosphere, either by simply ejecting it back into the space or by sending it to a collection chamber of some sore (such as a bag).  By creating a negative pressure (slight partial vacuum) in the space, they confine dust and other particles within the space so that they do not spread to other areas of the building.  They also ventilate the space by pulling in air either through vents or through leaks around doors and other openings.

 

Feed Air:  Generally adapted for the needs of a specific application or manufacturer, ACBs used to provide feed air generally supply a specific application such as a bank of air compressors in a dirty environment or combustion chamber in a furnace or oven.  They can stand alone or be installed in a duct.

 

Pre-Cleaning Air:  These units serve to greatly reduce the costs of providing clean air by pulling most of the mass of particles out of the airflow before they reach the expensive HEPA, activated carbon, and other special-application post-filters downstream.

 

Spot-Cleaning Air:  Spot cleaning air blowers stand-alone and serve to blow clean air to applications in small portions of a large facility or even outdoors.  Typical applications include blowing clean air over work stations, individual people or pieces of equipment.
