Product Description

Product Description

Variable air volume air handling systems are often employed in modern laboratory and hood systems. A fast and stable control system for the hoods, exhaust fans, supply fans, and all HVAC equipment is suggested. The airflows required are determined by the highest demand of the minimum ventilation rates prescribed, the cooling or heating loads required, and the total amount of exhaust from the hoods themselves. The airflow in and out of the room is controlled to meet these needs. Sometimes, the airflow required is below the amount needed to cool or heat the room to its comfort settings; therefore, the room supply air must be increased to meet the load. The lab control system must react to exhaust additional air through a "general exhaust" damper or air valve to compensate and maintain room pressurization and hood equilibrium.

Typically, the room is kept at a slight negative with respect to its adjacent corridors. Controlling the total supply air to be a little less than the total exhaust is what performs this. There are, however, situations where a positive pressure laboratory is required based on the type of experimentation being done.

More About the Fume Hood

Fume hoods are typically used in laboratories to collect and exhaust fumes. The cross-section of a hood below has a vertical sash which can be raised and lowered as necessary. The horizontal air velocity into the hood is, typically, maintained at a constant velocity of 80-100 fpm whatever the sash height.


When the hoods are not operating, the room control is much the same as a normal occupancy for a variable air volume controlled room. When the hoods are operating, the control system senses the flows and pressures in the room, hoods, and ducts in and out, and makes adjustments to maintain the temperature, humidity, and pressurization of the room. The objectives for control in laboratory hoods are for the capture and containment of fumes and harmful gases, to maintain acceptable room pressurization, to maintain acceptable temperature and humidity set points, and to ventilate the space in order to preserve dilution of contaminants.

Many conditions can affect performance and speed of response from the control system. There are great cost differences between desired levels of control for these systems; the designer needs to know and account for the accuracy and reliability of controls required for the process.

Fume Hood Maintenance
 

Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.

• In case of exhaust system failure while using a hood, shut off all services and accessories and lower the sash completely. Leave the area immediately.

 Fume  hoods should  be certified, at  least annually, to ensure they are operating safely. Typical tests include face velocity measurements, smoke tests and tracer gas containment. Tracer gas containment tests are especially crucial, as studies  have shown that face velocity is not a good predictor of fume hood leakage.

• Laboratory fume hoods are one of the most important used and abused hazard control devices. We should understand that the combined use of safety glasses, protective gloves, laboratory smocks, good safety practices, and laboratory fume hoods are very important elements in protecting us from a potentially hazardous exposure.

 Laboratory fume hoods only protect users when they are used properly and are working correctly. A fume hood is designed to protect the user and room occupants from  exposure to vapors,  aerosols, toxic  materials,  odorous,  and  other  harmful substances. A secondary purpose is to serve as a protective shield when working with potentially explosive or highly reactive materials. This is accomplished by lowering the hood sash.
FAQ

6 Questions to Ask When Buying a Fume Hood:

-Which chemicals will you use within the hood?

-Is a ducted or ductless hood best suited to your needs and available space?

-Where will you place the fume hood in the lab? Consider workflows, access to external exhaust systems, and competing air patterns.

-What size fume hood will best suit your needs? Be sure to consider what (if any) equipment will be enclosed in the hood.

-Are any service fixtures or accessories such as airflow monitors, electrical outlets, water, or gas fixtures required?

-Are base cabinets for acid, solvent, or non-chemical storage required?
