IP67 Fan for Harsh Environments

Ingress Protection or simply IP protection is becoming more common in the market place as fans are being designed into more applications that are exposed to elements that can be very punishing.
Many customers need extra protection from the elements in their applications. The most common kind of protection are the IP ratings set for enclosures. YS TECH currently offers IP43, IP44, IP55 and now IP67. You are probably wondering which one is the right one for our customers.

Here is a break down of the level of protection for each:

  • 1 IP43: varnish coating, moisture proof
  • 2. IP44: conformal coating, splash proof
  • 3. IP55: Paralyene coating, submergible
  • 4. IP67: Encapsulated motor with complete protection.
    • The encapsulated motor makes this model ideal for very harsh environments in all applications. The motor is completely potted, including the lead wires. This helps with the wicking that occurs on the lead wires making them a very weak link in highly corrosive environments. This process can be applied to all fans with a thickness greater than 20mm. Further development is underway for thinner models, we will keep you posted on the progress.

      * IP Code (or International Protection Rating sometimes interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits. The International Electro technical Commission (IEC) classifies the amount of stress or threat from intrusion of external elements a component can withstand without failure. Elements such as dust, accidental contact and amount of moisture in application are considered. The goal of these standards is to provide more tangible understanding of vague terms such as “waterproof”.

      First Digit of IP Code
      The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

      Object Size Effective Against
      No protection against contact and ingress of objects
      >50 mm
      Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
      >12.5 mm
      Fingers or similar objects
      >2.5 mm
      Tools, thick wires, etc.
      >1 mm
      Most wires, screws, etc.
      dust protected
      Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact
      dust tight
      No ingress of dust; complete protection against contact

      Second Digit of IP Code
      Protection of the equipment inside the enclosure against harmful ingress of water.

      Object Size Effective Against
      no water protection
      Vertically dripping water
      dripping 0° to 15°
      Vertically dripping water angle up to 15° normal position.
      spraying up to 60°
      Water falling as a spray any angle up to 60° from vertical
      Water splashing against from any direction
      Water projected by a nozzle against from any direction
      powerful jets
      Water projected in powerful jets from any direction
      immersion up to 1 M
      Ingress in harmful quantity not possible (up to 1 M).
