Thanks Rabar10!
IP Code - Wikipedia
Ingress protection of an enclosure. First number is against solids i.e. dust, rocks, fingers; second number is against water.
IP33 signifies no openings larger than 2.5mm for solid object protection, and protection from water falling at an angle up to 60 degrees from vertical.
IP54 signifies no solid object contact and minor dust protection, and protection from water splashed from any angle/direction.
IP56 improves on IP54's water rating to protect against pressurized water jets from any angle/direction.
Being a fan (designed to move air), I wouldn't ever expect a high solid object rating for these units.
