Maintaining the Filtering System
Like all high quality video projection units, the DL-1 fixture must be kept protected
from excessive amounts of glycol fog, mineral oil, and smoke. DL-1 fixture is
equipped with a two-stage air filtering to reduce these risks to a minimum:
•
The prefilter is designed to keep out large dust and debris such as from
pyrotechnics and confetti.
•
The HEPA filter is designed to aid in filtering small particles of dust, cigarette
smoke, fog and haze. The HEPA filter will require changing more often if the DL-
1 is exposed to theatrical fog or smoke. Depending on the levels of exposure
filter life can vary dramatically.
The Projector housed inside the DL.1 fixture contains an additional filter.
Fixture filters should be checked and cleaned on a regular basis. When used in a
closed or fixed environment where fog or haze is used, a weekly check is
recommended.
