Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures – IP Code), specifying the environmental protection the enclosure provides. Formally speaking, “IP” can be followed by one, two, or three numbers where the second number is for water resistance. An X can be substituted for the first number (collision or bump resistance) if it is not available. In practice, sometimes the first number is omitted entirely and so the only number shown is for water resistance.
Format: IPnn, IPXn, IPnnn
(e.g. IPX4, IP54, IP-4 would all mean a level 4 water resistance.)
Description:
| 0 | No protection |
| 1 | Protected against vertically falling drops of water e.g. condensation |
| 2 | Protected against direct sprays of water up to 15o from the vertical |
| 3 | Protected against splashes and direct sprays of water up to 60o from the vertical |
| 4 | Protected against low pressure water sprayed from all directions |
| 5 | Protected against moderate pressure jets of water from all directions |
| 6 | Protected against temporary flooding of water |
| 7 | Protected against the effect of immersion between 15 cm and 1 m |
| 8 | Protected against long periods of immersion under pressure |
Some popular dryers with published IP ratings:
The FEGOO HAND DRYER (FG2006,ECO9966,) has an IP44 rating which is almost the highest， that we’ve seen in a hand dryer.
