Explosion Proof Heat Resistant Stainless Steel Fume Hood for Chemical Laboratory

This is a four-part question: I. How wide do you want the fume hood to be? II. Will there be equipment enclosed in the hood? III. What are the dimensions of the equipment? This information is essential to determining how deep the hood needs to be to house your equipment. IV. Do you need a bench-top or floor mounted hood? Applications that use extra-large equipment, such as 50-gallon drums, or applications that require equipment to be wheeled into the hood via a cart would require a floor mounted

These include (but are not limited to) airflow monitors, electrical outlets, compressed air, laboratory gas, vacuum and cold water fixtures. Gooseneck faucets are also available. Finally, do the fixtures need to be factory installed, or will the installer handle that at the job site by using field-installed kits?

Do you need a work surface and base cabinets, or will you be using existing casework to support the hood? If you do need base cabinets, do you need acid storage, solvent storage or non-chemical storage? Do you need ductwork from the hood to the roof, or will your HVAC contractor provide it?

Every fume hood needs a blower, and it is often misconceived that a blower comes attached to a fume hood. Will there be a dedicated blower (exhaust fan) for this hood, or will it connect to a central exhaust system? If it connects to a central system, will it be constant volume or variable air volume? If you already have a blower, and it is sized appropriately, you can stop right here: Contact Labconco if you'd like us to finalize your fume hood selection.

Built-in blowers are easier to install (and therefore less expensive), but they can be noisy and they put the ductwork under positive pressure, so they should be reserved for non-hazardous applications, short duct runs and instances where a remote blower cannot be installed (such as a mobile lab). Remote blowers, though more complex to install, can be sized for the specific situation and keep the ductwork under negative pressure for safer operation.
