• The dust filter is a single-use component.
• Use the dust filter (A907-FAN-F) within 6 months of buying as the shelf or storage life is less than 6
months. The ideal storage condition for a filter is a cool, dry, and dark environment. Surroundings that
adversely affect the dust filter are high heat, humidity at high temperatures, and ultraviolet light.

Dust Filter Maintenance
A periodic health check of the filter, every three months based on the level of dust in the environment helps
in avoiding over clogging of the filters and provide better life. The product's filter may be used as a single
use or reused depending upon the local deployment needs. If reuse of the filter is prohibited, it may be replaced
every six months with the part number (A914-PWR-FAN-F=) or equivalent.
Avoid using harsh solvents or cleaning agents.
