What is a CAV constant air volume damper?
What is a CAV constant air volume damper?Constant air volume valve (CAV) is a mechanical self-operated device, also known as CAV damper, suitable for ventilation and air conditioning systems that require constant air volume. The air volume control of the constant air volume valve does not require external power. It relies on the air force in the air duct to locate the position of the control ...

Using thimbles to connect Biological Safety Cabinets to Variable Air Volume (VAV) Exhaust Systems
Abstract Variable-volume exhaust systems are a common feature of laboratory ventilation designs. By reducing exhaust airflow in proportion to the actual need, the system uses less energy to condition the make-up air. However, variable exhaust flows can disturb the critical pressure relationships between air flows in biological safety cabinets, which require a constant airflow to maintain ...

Introduction to the internal structure of the wet scrubber, spray device and defogging device
The organic waste gas is introduced into the scrubbing tower through the air pipe, and passes through the packing layer. The waste gas and the sodium hydroxide absorption liquid undergo gas-liquid two-phase full contact, absorption and neutralization reaction. Into the atmosphere. The absorption liquid is sprayed down at the top of the tower after being pressurized by a water pump at the bottom ...

Corrosion, the invisible enemy of WWTPs
Corrosion is the natural process in which metals degrade. This process is influenced by external factors such as humidity, temperature and corrosive gases, mainly active sulfur compounds, sulfide oxides and nitrogen oxides (H2S, SO2, SO3, NOx). In pumping stations and sewage treatment plants these factors are present, even in very low concentrations (parts per billion), and are the cause of ...

How To Conserve The Most Energy With Your Fume Hood
Fume hoods are constantly exhausting air away from the laboratory while forcing clean air back in. This continuous cycle can result in a single fume hood consuming as much energy as 3-4 homes in a year. Laboratories with more than one fume hood face even higher energy consumption and operating expenses. To keep expenses low, follow these energy-conserving tips. Turn it off As with many ...

Biological Safety Canopy Exhaust Connection Saves Energy and Improves Overall Safety Performance
Abstract With environmental resources becoming more and more limited and energy costs on the rise, reducing energy consumption is an important consideration for every laboratory. It is especially important in light of an analysis published by the US Environmental Protection Agency concluded that laboratories consume five to 10 times more energy per square foot than typical office buildings.1 As ...

Innovative Technologies Result in a More Sustainable and Energy-Efficient Total Exhaust Biological Safety Cabinet
Abstract Biological safety cabinets (BSCs) provide the primary source of containment for microbiological research. Laboratories that need containment and removal of vapors, mists and particulates will often choose a Class II, Type B2 total exhaust BSC (Type B2). Because this type of BSC must be totally exhausted to the outside through a facility’s HVAC system, it requires a great deal of ...

How Does A Fume Hood Work?
By definition, a fume hood is a ventilated enclosure that is designed to limit exposure to hazardous or toxic fumes, vapors, or dusts. As the most important appliance in a laboratory, fume hoods keep employees safe by removing harmful vapors and chemicals from the work area. The air they extract is then filtered by the building’s exhaust system before exiting the facility. That, right ...
