General info regarding Air intake and filters.

The product is shipped default without any filters and by avoiding filters, the ventilation system operates for longer periods between maintenance, since no clogging of filters means more air is allowed through the system, resulting in lower operating temperatures over time. The air intake are just protected by a mesh. This mesh has to be vacuum cleaned occasionally when needed. No specific interval for this operation, but to be performed when needed.

For more demanding surrounds both smoke and dust filters can be applied externally to the system to avoid internal fouling.

General guidelines for cleaning projector filters (external)

Remove the filter from the projector then use a vacuum to remove excess dust from the filter. Do not wet or soak the filter.

Note: Cleaning of the projector filter should be done in a separate room to avoid dust contamination.
