The particle identification system ASHIPH (Aerogel, SHIfter, PHotomultiplier) has been working in the KEDR experiment at the VEPP-4M e+ e- collider (Budker INP, Novosibirsk), without interventions and upgrade, since 2014. The system consists of 160 aerogel Cherenkov counters containing aerogel with refractive index of 1.05. The ASHIPH system provides separation π/K in the momentum range from 0.6 to 1.5 GeV/c. The status of the system is presented. The long-term stability of aerogel counters in the KEDR experiment is studied. The use of the ASHIPH system in physics analysis is presented as well.
