- Damper Application Considerations for Laboratory Exhaust Systems
Most of the focus of a laboratory exhaust system is on the fans. Overlooking the construction, sizing, and control of the isolation and bypass dampers can result in operating difficulties and system failure. Understanding damper design and applications in laboratory exhaust systems is critical to the success of the design, installation and control of the laboratory exhaust system.

Visit Site - New Test Standard for Dilution Blowers
For reasons of safety and health, not to mention litigation, consulting and facility engineers have long insisted on independent performance verification for fans and blowers used in general HVAC, as well as more critical applications. With their unique discharge design, however, high plume dilution blowers - used to dilute hazardous laboratory exhaust and disperse it high into the atmosphere, away from possible re-entrainment zones - fell outside the scope of Air Movement and Control Association (AMCA) International performance certification. That changed with the recent publication of AMCA Standard 260-07, Laboratory Methods of Testing Induced Flow Fans for Rating.

- Optimizing Dedicated Outdoor-Air Systems
Though vital to maintaining good indoor-air quality, outdoor air can be expensive to temper and, if not conditioned properly, cause humidity problems in a building. Increasingly, however, designers are finding dedicated outdoor-air systems (DOAS) to be an energy-efficient and easily verifiable way to comply with ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality.
