Ingress Protection (IP) series
telecom

Professional Grade IP56 and IP55: Durable, Reliable, and Weatherproof.

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
IP Reference Table:
IP
IP Code and IP56 / IP55 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.
IP
Please refer to the below table for an explanation of what IP is. IP is defined as Ingress Protection.
The first digit indicates protection from solid particles while the second digit indicates protection from liquids.
Protection against solid particles Protection against liquids
0 No protection 0 No protection
1 More than 50mm, e.g. accidential touch by the back of a hand. 1 Dripping water (vertically falling drops)
2 More than 12.5mm, e.g. a finger. 2 Dripping water (when tilted up to 15°.
3 More than 2.5mm, e.g. a tool. 3 Spraying water (at any angle up to 60°).
4 More than 1mm, e.g. a wire. 4 Splashing of water (any direction).
5 Dust-protected (Dust shall not penetrate in quantity to interfere with satisfactory operation of the apparatus or to impair safety). 5 Water jets.
6 Dust-tight (No ingress of dust). 6 Powerful water jets.
    7 Immersion, up to 1m depth.
    8 Immersion, 1m or more depth.
