Features and ATEX Certification
The Delfin PHARMA 20.18 ATEX is a compact, stationary dust extraction unit certified to ATEX II 3D Ex h tc IIIC T80°C(int)/T165°C(ext) Dc and approved for permanent installation in Zone 22 explosive dust atmospheres. The unit combines pharmaceutical-grade stainless steel construction with maintenance-free side channel blower technology. H14 HEPA absolute filter and IP65 rating ensure maximum safety in sensitive processes.
Zone 22 certification means the extractor operates in environments where explosive dust atmospheres occur rarely and only for very brief periods during normal operations. The maintenance-free design with no carbon brushes, electrical friction, or wearing parts makes it suitable for continuous 24/7 operation without scheduled downtime.

Frequently Asked Questions
ATEX Zone 22 certification means the dust extractor is approved for operation in explosive dust atmospheres where such dust occurs rarely and for brief periods during normal operations. Zone 22 is the lowest-risk classification under EU Directive 2014/34/EU and the EN 17348:2022 standard.
The side channel blower has no carbon brushes, electrical friction, or other wearing parts. This means the unit can run 24/7 without scheduled maintenance stops. No fluid changes or component replacements are necessary under normal operating conditions. Perfect for pharmaceutical production where uptime is critical.
Yes. The H14 HEPA absolute filter is included standard on all PHARMA 20.18 ATEX units. It ensures 99.995% particle retention at MPPS and is certified per EN 1822:5. This provides both excellent exhaust air quality and machine protection.
IP65 means the unit is completely dust-tight and protected against water jets from any direction. This ensures full protection of electronics and motor components in moist industrial environments, washdown areas, and outdoor installations.
Yes. PHARMA 20.18 ATEX is engineered for continuous operation without planned maintenance stops. The side channel blower is rated for 24/7 duty. This makes it ideal for pharmaceutical production lines where GMP compliance demands continuous process availability.
AISI304 is stainless steel containing 18% chromium and 8% nickel. It has excellent corrosion resistance, chemical durability, and heat tolerance. AISI304 is standard in pharmaceutical, chemical, and food industries where cleanliness and chemical resistance are critical.
