Multi-Station Fume Extraction

Concept Design

Portable Floor Sentry

This multi-operator fume extraction system is a conceptual design by Sentry Air System’s mechanical engineers that is intended to incorporate up to 20 workstations with bench-top fume extraction access. This system is engineered using a Sentry Air Model 450 Fume Extractor that can be affixed to appropriate tubing or piping (not included) and outfitted with the desired amount of self-supportive flex arms. Sentry Air Systems will supply the fume extractor and flex arms, but will not be responsible for tubing/piping or the attachment of any elements of the apparatus.

Typical uses of this unit might include solder fume removal, chemical fumes removal, light grinding, and various other industrial processes.

The Model 450 Fume Extractor will deliver a specified air flow that is dependent on the amount of arms attached and the length of piping utilized. Based on factory testing, the chart below demonstrates the approximate CFM (cubic feet per minute) for both Sentry Air’s HEPA filter (with pre-filter,) as well as our 22lb. Carbon Filter based on the number of arms attached:
