The AerPro Model 1MV Series is designed for safe and efficient ambient collection of process dusts, mist , and smoke.

Concept of Ambient of Free-Hanging Air Cleaners

  • Ambient or Free hanging – Locating air cleaners in a space which they are free to blow and draw air as they can. No ductwork is connected between the unit and where the particulate is created.
  • “T” or Criss-Cross Air Pattern – Locating air cleaners in a facility such that a pattern of air discharged from the air cleaner crosses the area to be captured by another in a back and forth pattern, from unit to unit.
  • Race track pattern – Locating air cleaners in a facility such that air is caused to move around the space in a oval racetrack pattern.

The “T” cross flow allows for the unit(s) to blow across the room with the airflow coming into the unit from each end. This type of air pattern is very useful for wide rooms or areas such as welding bays.

The inlet area acts like a catcher’s mitt, One question that is always asked, is how does the dirty air in the center of the room get to the unit? When the unit(s) are on, the air stream coming from the blower produces a high pressure zone. The inside air is a low-pressure zone. The low-pressure zone rotates to the direction of the high pressure and slowly feeds into the high-pressure air stream. 

There is always a portion of the dirty air rising into the airstream in addition to the amount of suspended dirty air particles trying to get captured in the airstream. Because of this limitation a free hanging system can never achieve 100% efficiency. However, efficiencies that range from 60% to 90% can be achieved.
