Overview
What is AIRFORM SEAL REAR?
AIRFORM SEAL REAR is the companion to the AIRFORM SEAL SIDE skirt sealing system. It is mounted on an existing AIRFORM SEAL SIDE unit and closes off the transfer zone, reducing dust and material spillage. AIRFORM SEAL REAR works on a similar principle to AIRFORM SEAL SIDE.
Its lamella structure is based on the Venturi principle and creates negative pressure in the transfer zone. This negative pressure keeps material and dust from leaving the belt. Incoming air holds dust inside the material flow, while the special lamellas reduce spillage with coarse material. Because AIRFORM SEAL REAR runs without touching the belt, it needs little maintenance.
AIRFORM SEAL REAR is available in small, medium and large sizes and is designed to fit the AIRFORM SEAL SIDE variants. With less spillage and dust, the area around the transfer zone stays cleaner and less time goes into clean-up.
Features
Key features
Venturi-based lamellas
The lamella structure creates negative pressure in the transfer zone, which keeps material and dust from leaving the belt.
Contactless operation
AIRFORM SEAL REAR does not touch the belt, so the belt is not damaged and the sealing does not wear by friction.
Air intake
Incoming air keeps fine material and dust inside the material flow, so less dust spreads from the transfer zone.
Mounts on AIRFORM SEAL SIDE
AIRFORM SEAL REAR is mounted on an existing AIRFORM SEAL SIDE unit and works together with it, so it can be added later to lines that already use AIRFORM SEAL SIDE.
Three sizes
The small, medium and large sizes are designed to fit the AIRFORM SEAL SIDE variants; the size is chosen to suit the AIRFORM SEAL SIDE unit on the line.
How does it work?
- Mounting on the unitAIRFORM SEAL REAR is mounted on an existing AIRFORM SEAL SIDE unit.
- Negative pressureThe lamellas create negative pressure in the transfer zone on the Venturi principle.
- Closing the transferIncoming air keeps dust inside the material flow.
Benefits
- Efficient with coarse material and reduced spillage
- Efficient with fine material thanks to the air intake
- Reduced dust generation
- No belt contact, so no belt damage
- Prevents friction wear on the sealing
- Lower maintenance and replacement costs
- Easy installation and short downtime
- Can be added to an existing AIRFORM SEAL SIDE unit
- Supports occupational health and environmental protection, as dust and spillage are reduced
Options
Size options
AIRFORM SEAL REAR is available in small, medium and large sizes. The sizes are designed to fit the AIRFORM SEAL SIDE variants.
Applications
Transfer zone
AIRFORM SEAL REAR closes off the transfer zone of the conveyed material and reduces dust and spillage at this point.
Existing AIRFORM SEAL SIDE lines
On lines that already use AIRFORM SEAL SIDE, AIRFORM SEAL REAR is mounted on the existing unit.
Lines carrying coarse and fine material
AIRFORM SEAL REAR reduces spillage with coarse material and keeps dust inside the material flow with fine material.
Occupational health and environmental protection
In operations that need to reduce dust emission and spillage, AIRFORM SEAL REAR supports occupational health and environmental protection.
