IP69K - certified DC axial fans redefine durability, engineered to withstand high - pressure steam cleaning (80 bar at 80°C), dust ingress, and corrosive agents. This rating makes them indispensable in hygienic and harsh industrial environments.

Robust Sealing Architecture

Housing Design: 316 stainless steel or PPS (polyphenylene sulfide) housings feature double - lip seals and recessed fasteners to eliminate crevices. Gaskets use fluoroelastomer (FKM) for resistance to oils and chemicals.

Motor Protection: Encapsulated stators with epoxy resin and hermetically sealed rotors prevent water penetration. Some models use oil - filled chambers to lubricate bearings indefinitely.

Impeller Engineering: CNC - machined aluminum impellers with hydrophobic coatings reduce water adhesion, while balanced designs minimize vibration under high - pressure 

Operational Resilience

Cleaning Compliance: In food processing, these fans withstand daily CIP (clean - in - place) cycles with caustic detergents, maintaining performance after 10,000+ cleaning cycles.

Dust Resistance: A tight - weave stainless steel mesh guards the intake, filtering particles as small as 1μm, critical for pharmaceutical lyophilizers.

Temperature Extremes: Models rated for - 40°C to +125°C operate in autoclaves and deep - freeze warehouses, with silicone wire insulation ensuring electrical integrity.

Industry - Specific Applications

Pharmaceuticals: 100mm fans in isolators maintain ISO 5 cleanliness, resisting hydrogen peroxide vapor sterilization.

Marine: 150mm IP69K fans cool engine rooms, enduring saltwater spray and constant vibration.

Chemical Plants: Fans with PTFE - coated components handle acidic fumes in fertilizer production.
