Ventilation systems are necessary to remove odors or humidity from a space. Restaurants, Industrial Buildings, Sports Complexes, and Restrooms all require proper ventilation systems. REE has experience in finding the right application for your space to create a comfortable space for you and your employees.



A clean room is an environment, typically used in manufacturing or scientific research, that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. Clean rooms can be very large. Entire manufacturing facilities can be contained within a clean room with factory floors covering thousands of square meters. The air entering a clean room from outside is filtered to exclude dust, and the air inside is constantly re-circulated through high efficiency particulate air (HEPA) and/or ultra low particulate air (ULPA) filters to remove internally generated contaminants. Some clean room HVAC systems control the humidity to low levels, such that extra precautions are necessary to prevent electrostatic discharge problems.
