Compliance Certifications
This unit complies with EU Directive 2014/34/EU for ATEX certification and is tested according to EN 17348:2022. ATEX II 3D means the unit is approved for Zone 22, where explosive dust atmospheres are not expected to occur under normal conditions.
Frequently Asked Questions
ATEX II 3D Zone 22 means the unit is certified for areas where explosive dust atmospheres are unlikely to occur (less than 10 hours per year). It is the least restrictive ATEX zone classification for dust.
Side channel blowers have no brushes or wearing parts, making them maintenance-free and ideal for continuous operation. They are also highly reliable in high-pressure applications.
Yes, H14 removes 99.995 percent of particles greater than or equal to 0.3 micrometers, meeting pharmaceutical standards such as GMP, USP, and FDA requirements for cleanroom and isolation scenarios.
Yes, it is designed for continuous 24/7 operation thanks to its maintenance-free motor. The only service task is periodic filter replacement.
IP65 means dust-tight and water-resistant. The unit is protected against dust and can withstand direct water spray, ideal for wash areas and humid environments.
DBFV features an integrated vortex pre-filter that increases efficiency and reduces filter clogging. Choose DBFV if your dust is particularly heavy or sticky.
