Ventilation Systems

REES provides Ventilation Systems to continually remove and supply air to a particular area in the plant where a controlled environment is needed to eliminate physical hazards or maintain temperature and humidity conditions.

Many industrial facilities have processes that produce hazardous dusts, vapors, or gases requiring an exhaust system to prevent exposure to workers. The system must capture and convey the contaminants, clean the air, recover any valuable material, and prevent any further air pollution.

In designing a ventilation system, REES integrates four key components to achieve project goals:

Components to Meet Project Goals


Hoods must be designed properly to effectively contain air contaminants with consideration of capture velocity, location, and workstation limitations.


Ductwork must also be effective by maintaining the required conveying velocity and using best practices for the design pipe, elbows, and fittings.


The selected fan must be specified to handle exhaust air, fumes, vapors or gases, and be sized to convey the air properly.

Filter Separator

A separator or control device must include the proper filtering media such as impingement baffles, bag filters, HEPA filters, and carbon filters with considerations for the air-to-cloth ratio.
