Dust-reducing filling nozzles

Dust-reducing filling nozzles are transfer components with an integrated baffle + diffusion chamber for minimal aerosolisation. Reduction is important because: (1) prevents inhalation exposure, (2) minimises environmental contamination, (3) improves operator safety without a separate isolation cabinet, (4) cost-effective alternative for OEB 1–3 applications.

Typically 60–80% reduction vs. a standard filling head. Depends on powder properties (particle size, density, hygroscopicity). HECHT provides performance testing per product type on request.

No. Dust-reducing filling nozzles are designed for OEB 1–3 (low-potency, non-hazardous). For HPAPI, use minimal dead-leg filling heads or full isolation systems (SE-H, EWI).

Flow rate is approximately 20–30% lower than standard (baffles reduce flow). Standard: ~80 kg/min vs. 100 kg/min without dust suppression. Trade-off: slower transfer = better aerosolisation control.

Yes. GMP Annex 1 compatible, GAMP 5 validation protocols available. Stainless steel construction pharma-compliant. Validation: 2–4 weeks including dust-reduction testing.

Manual rinsing with steam or a selected solvent. Baffles are easily accessible without disassembly. Typical clean cycle: 15–20 minutes. CIP-compatible for facility protocols.

DN30, DN50, DN80 connector options. Compatible with dosing gates, dosing columns, standard transfer lines, endless liners. Retrofit adapters available for existing non-Hecht equipment.

Minimal. Baffle design minimises residue (<1 mg per cycle). Product recovery >98% with a simple return chute. Aerosolisation reduction ≠ product loss.
