Engineering Controls » Central Vacuum System
A central vacuum system is used by plant personnel to remove lead oxide dust from their workstations. Tools can also be connected the system to capture dust at the source of generation for some operations, such as grinding.
Design of a central vacuum system depends on the number of active work points (hoses and tools) operating at the same time that is desired. Sometimes, the system would be very large and expensive if the number of active points is high. The size and cost of the system can be reduced by:
Staggering the clean-up period.
Minimizing the number of active stations used at any one time.
Manufacturers and vendors of the equipment will size the vacuum unit, filter or bag unit, centrifugal separator, and bleed control with a silencer to suit the final number of work points.
If a drawing or dimensional sketch is provided to the supplier, most suppliers will size the collection system, tubing, fittings, and headers, along with the type and number of fittings required to match the application.
The choice of the length and type of hose, along with the type of tools needed, depend on the workstation. Suppliers can provide listings of available accessories, shutoff valves, tools, and hoses.
To have an efficiently operating system, the installation of the equipment should conform to the supplier's instructions. All piping, work points, and valves should be properly supported.
