Vacuum System
Air-based capture of film, fluff, and ultralights — the fraction no belt or screen can hold onto, pulled clean out of the stream.
The Sherbrooke OEM vacuum system position integrates an industrial vacuum package (Rodair GVS class or equal): capture hoods over the line draw film, fluff, and ultralight contaminants into ducting, a cyclone with blower separates the air from the captured material, and rotary valves discharge it through a drop box into the residue or film stream. On C&D lines this is the fluff and ultralights capture; on container lines it cleans film off the glass-rich fines. Hood placement, duct routing, and airflow are engineered per position by Sherbrooke OEM in Sherbrooke, Quebec.
Where It Fits
- Fluff and ultralight removal on C&D fines lines, often after the fines knife
- Film cleanup on glass and container fractions in MRFs
- Quality polishing anywhere lights contaminate a heavy product
Configuration & Options
Every unit is engineered per project — these are the configuration choices and options we quote against, not limits.
| System class | Industrial glass/film vacuum system (Rodair GVS class or equal) |
|---|---|
| Capture width | Hoods sized to the belt — engineering default around 48 in |
| Cyclone | Cyclone with blower, rotary valve, and support structure |
| Drop box | With rotary valve and support — discharges to the residue or film stream |
| Airflow | Engineered per capture point and material |
Construction
| Hoods & ducting | Formed and welded steel, engineered per capture point |
|---|---|
| Cyclone | Steel cyclone with blower package and support stand |
| Rotary valves | Airlock discharge at cyclone and drop box |
| Supports | Bolted structural steel, braced and mechanically anchored |
| Guarding | Rotating equipment guarded to OSHA requirements |
Vacuum System — Frequently Asked Questions
Why use air to sort instead of another screen?
Film and fluff defeat mechanical sorting: they drape over discs, wrap shafts, and ride every fraction they touch. Air is the one force that grabs them preferentially — their surface-to-weight ratio makes them the easiest thing in the stream to lift, and the hardest for anything else to follow.
Where do vacuum points go on a line?
Where the lights concentrate and the product suffers most — over the glass-rich fines on a container line, after the fines knife on C&D, above transfer points where film lofts naturally. Each capture point is an engineered airflow, not a generic hood.
What keeps the system from swallowing good product?
Airflow tuning. Hood height and air velocity are set so only material below the target weight lifts; the cyclone then drops the captured fraction out of the airstream for controlled discharge through the rotary valves. Velocity is adjustable at commissioning per stream.
