Delta IP55 Blowers

Delta Ingress Protection (IP) rated fans are purpose-built with superior production techniques to prevent dust and water ingress in harsh conditions. IP fans undergo the most rigorous testing against harsh environments, including:

  • Rain and flooding
  • Salt, fog, and moisture
  • Severe dust and dirt exposure

Delta Environmental Proof Fans: In an outdoor environment, spray of water, exposure to dust particles, unexpected corrosion and high humidity, all will cause the electrical device to work improperly. Delta’s environment proof fans are designed to use a potting method to seal the PWB to isolate the outside environment. Bypassing the most common standards validation (IP and Bellcore), Delta’s environment proof fan can withstand outdoor environment or similar condition.

IP Code Protection:

The IP Code classifies and rates the degrees of protection against the intrusion of solid objects, such as hands and fingers, as well as dust, accidental contact, and moisture or water.

The enclosures are critical to the lifespan and efficient operation of any fan, and are built to withstand specific intrusions. To ensure greater durability, Delta provides IP55 and higher protection ratings as an industry standard.

  • The first numeral is the protection rating against dust.
  • The second numeral is the rating for protection against water jets.
