Benelabo Wurster bottom spray guns cover six ELS-diPQ models for lab-to-production fluid beds — anti-clogging tips, independent liquid/air lines and quick-detach nozzles for continuous pellet film coating.
Highlights
Gun centered to the Wurster partition keeps the spray cone on the fluidizing ring — film thickness stays even.
Independent liquid/air lines let you tune spray rate and atomization separately.
Quick-detach nozzles and needle-valve anti-clogging tips.
Applications
- Micro-pellet sustained-release film coating
- Layering powders onto pellets (drug layering)
- Taste-masking and moisture-protection films

FAQ
Why is my Wurster bottom spray gun clogging during pellet coating?
Typical causes are binder drying at the nozzle tip and misaligned gun-to-partition positioning. Benelabo guns use anti-clogging tip design, precise centering to the partition, and quick-detach nozzles so cleaning happens between batches, not during them.
Can the bottom spray gun replace my original imported spare parts?
Yes — gun sets are engineered to your machine’s mounting and connections, delivering equivalent atomization with shorter lead times and lower maintenance cost.
How do I achieve uniform film coating on pellets?
Stable atomization (constant liquid/air ratio), correct gun-to-bed distance and a consistent spray rate. We size all three from your pellet size and coater model, and confirm by sampling trials.
