*IP55
The fan inside the TS-200 is extremely well sealed against water and dust, with an ingress protection (IP) rating of
55, called IP55. Higher numbers indicate better protection. Fans typically range from IP11 to IP55. The first digit in
the IP rating indicates protection against particle entry. A 5 indicates minimal dust entry with no interference with
fan operation. The second digit indicates water protection. A 5 indicates that water sprayed on the fan from any
direction shall have no harmful effects. Typical fans have particle and water protection ratings of 2 to 3, indicating
moderate particle and water protection, but no dust protection. Apogee Instruments also offers a 24 V DC fan
option for purchase.
