Dell Network Equipment Air Filter

This document provides some basic guidelines regarding the stocking, care, and useful service life of air filters in a typical, telecommunications system application. This information is based on industry standards, common practices, material properties, customer comments and our experience.

Storage

Since storage of air filters can be subjected to various environments beyond our control, no life expectancy (shelf life) is published. The ideal storage condition for telecom air filters is a cool, dry, dark environment. Surroundings that adversely affect the filter are high heat, humidity at high temperatures and ultraviolet light. The filter may degrade when exposed to solvents and sulfates, such as, cleaning agents and exhaust. Filter service life is reduced based on the severity of the digressions from ideal storage and operating conditions.

Replace Filters

Cleaning air filters is not recommended by major telecommunication carriers and service providers, the governing NEBS Standards have stated air filters should be replaced. NEBS GR-63-CORE, Section 4.1.5.2 Fan-Cooled Equipment Criteria, Requirement R4-27, states the following: “Equipment fan filters shall be single use and not the types that require cleaning.”

General Guidelines

  • Based on network equipment environmental criteria, telecommunications industry standards, thermal management concerns, and fiscal assessments, it is recommended air filters are to be replaced every three to six months, or within the recommended preventive maintenance schedule.
  • Storing air filters for more than 6 months is not recommended. Instead, purchase cost-effective quantities and keep sufficient inventories based on your replacement cycle. Telecom air filters have improved permanence (service life) in an operating situation with air movement and ventilation.
