ABB Blower Co. developes Make-Up Air Units for larger industrial plants ventilation requirements.

Negative Air Pressure in industrial manufacturing facilities can create problems such as:

* Exhaust fans losing performance, as the building pressure becomes negative.

* Pilot light outages and exhaust system failure on natural draft gas equipment.

* Cold air drafts and infiltration of dirt and contamination from outside.

* Difficulty opening or closing exterior doors.

ABB Blower air-handling units (AHU) can be used effectively for negative pressure control at manufacturing facilities:

Space Pressure Control is used to minimize and control the exchange of air between the building and the outside environment or from one building area to another. This may be accomplished in three ways:

- Constant air supply with variable-speed exhaust;

- Variable air supply with constant-speed exhaust;

- Variable Return-Air.

Constant air supply with variable-speed exhaust is recommended where a hot or contaminated environment must be ventilated while maintaining room pressure. Unit may be interlocked to that it only operates with the exhaust system.

Variable Air Supply with constant-speed exhaust may be preferred where fume exhausters or fume hoods are used to provide critical ventilation of contaminants from a “clean” environment while make-up air is used to maintain a positive pressure to prevent infiltration.
