Configuration Options for Source Extraction
Source extraction can be tailored specifically to the workstation using the appropriate arm, hood, mounting, and connection options. The key factor is not the largest possible design, but rather a configuration that combines the required working radius with the lowest possible pressure loss.
Typical configuration options
ā Arm length and connection diameter
ā Hose or pipe construction
ā Wall, ceiling, or floor mounting
ā Extension arm for greater reach
ā Hood shape and capture element
ā Lighting and Control Options
ā ATEX-compliant design for corresponding hazards
Consider range and air delivery together
As length increases, pressure loss and mechanical stress also increase. At the same time, connection diameter, the hood, and the duct routing influence the required flow rate. The configuration should therefore always be considered in conjunction with the fan or filtration unit.
Common Planning Mistakes
ā Choose an arm that is significantly longer than necessary
ā Determine the connection diameter based only on the existing line
ā Do not adjust hood size and air demand
ā Checking the mounting point and load capacity too late
ā Consider ATEX requirements in isolation rather than as a system
FAQ
What is a reasonable arm length?
The length should cover all standard work positions with a small margin, but should not be unnecessarily excessive.
Can a larger diameter offer advantages?
Yes, if the required flow rate is suitable. Diameter and air delivery must be evaluated together.
When is ceiling mounting recommended?
When the floor needs to remain clear or wall surfaces are not suitable.
Can ATEX simply be added as an option?
No. Explosion protection must be considered based on the specific risk assessment for the entire system.
Configuration tailored to the workplace
Factors to consider when selecting a model include the working radius, installation location, contaminant type, desired hood, connection diameter, and available extraction capacity.
