How do you select the right vacuum de-aerator for a specific application?
Vacuum De-Aerator Selection — Key Points and Guidelines
Key Points
- Selection criteria: Viscosity, temperature, throughput (kg/hour), residual air content requirement, and ATEX zone
- Standards: GMP Annex 1 (2022) pharmaceutical + EHEDG Doc. 8 food + ATEX 2014/34/EU + PED 2014/68/EU
- HECHT product: ProClean Conveyor with integrated de-aeration — OEB 1–5 configurations available
- Validation: Test & Trial Centre in Sonthofen (DE) for process validation before purchase
- ROI: Correct de-aerator selection prevents product and quality losses worth 10–25% of revenue

FAQ — Vacuum De-Aerator Selection
Which parameters are decisive in selecting a vacuum de-aerator?
The four main selection parameters are: (1) product viscosity and bulk density, (2) required throughput capacity in kg/hour, (3) maximum acceptable residual air content per product specification, and (4) environmental classification (ATEX zone, GMP cleanliness class). Hecht Technology uses these parameters in a selection matrix to determine the optimal de-aeration system — including free process advice.
How do I test whether a vacuum de-aerator is suitable for my product?
Hecht Technology offers free Test & Trial Centre testing in Sonthofen (DE) where your own product is processed in a scalable test setup. You receive a detailed test report with measurement results for throughput, residual air content, product temperature, and energy consumption — ideal as a basis for your investment decision and GAMP 5 URS.
Which vacuum de-aerator level is required for ATEX Zone 21 production environments?
In ATEX Zone 21 (dust explosion hazard), a de-aerator is required with Ex-certified motor (Category 2D), grounded construction per NEN-EN 60079-32, and explosion-pressure-resistant design. Hecht Technology supplies ATEX-certified de-aeration systems with complete EU type-examination certificate per Directive 2014/34/EU and ATEX marking on the nameplate.
