Downdraft Tables

Downdraft Tables

downdraft tablesAs well as metal working, welding or cutting, downdraft tables are also used for human dissection tables although rim exhausts are usually used for this purpose. For manual shoe repair and during application of artificial fingernails, downdraft tables are the only type of exhaust possible.

Larger versions are used for sanding, grinding, polishing, and welding. Since welding generates large amounts of heat together with the contaminants, a downdraft table, although handy, is not suited for this use. There could be problems with grinding, since the contaminants are generated with a high velocity in different directions and a downdraft table is only suited for capturing contaminants with low velocity and a temperature equal to or lower than room temperature. A partial solution to this is to surround the table on three sides with walls (0.2 to 0.5 m high) to deflect the generated contaminants and to diminish the amount of air pulled in from the sides.

Very large downdraft rabies have been used for sources such as electrocutting and welding of large steel sheets.

air flow of downdraft tableModification to processes can also indirectly reduce pollutant emissions. Using the histology labs as an example once again, special exhaust enclosures were designed to reduce energy consumption and employee exposure to chemical vapors. Histology staining dishes require a large amount of bench space, and as a result, employees will remove staining dishes from cramped fume hoods. Down draft tables are typically installed to protect the employees from chemical fumes, but these tables require an air flow of approximately 2000 cubic feet per minute (cfm) for proper operation. The air from the down draft tables cannot be recirculated and must be exhausted directly to the roof vent. Make-up air must be tempered and supplied to the histology labs. The University of Minnesota designed modular exhaust enclosure boxes to protect employees from exposure to the histological chemicals and to reduce air flow (and energy) requirements. These exhaust enclosure boxes reduce air flow requirements by 10 to 40 times over equivalent space used by down draft tables.

“When we first started we bought similar machines from several different manufacturers, and after 8 years, we now use exclusively Belfab to get the job done. We find them to be reliable and easy to clean. Whenever we need to buy another downdraft table, we do not even look anywhere else, it is going to be a Belfab downdraft table. Nothing can compare.”
