Positive Pressure

This system can be used to bring outdoor air through the air cleaner and create positive air pressure in the interior space.

This pressure forces the contaminated indoor air out and replaces it with cleaned outdoor air.

The positive air configuration is used in the Air Handler central air systems and may be used to feed clean air into a heat exchanger or air duct.

Negative Pressure

The negative air configuration draws the contaminated air in through the bottom of the unit and blows it out through the top.

This system can be used to move contaminated air from indoors to outdoors through the air cleaner and create negative air pressure in the indoor space.

This pressure draws outdoor air into the interior to replace the extracted contaminated air.

The air cleaner cleans the contaminated indoor air before releasing it outdoors to avoid creating outdoor pollution and to conform with environmental regulations.
