Air treatment system
First Claim
1. An air treatment system comprising:
- a system housing including a filter housing;
a plurality of filters arranged in said filter housing;
a blower for moving air through said plurality of filters;
a dust sensor for sensing a dust level;
a sensor configured to sense presence of an operator of the air treatment system;
a control system having an electronics module with a display having a plurality of display elements capable of being illuminated in a plurality of different configurations, said electronics module being covered by a translucent portion having a translucency selected to provide a dead front display;
wherein said control system is configured to selectively illuminate combinations of said plurality of display elements in a variety of configurations to provide a plurality of display states that present available control options based on one of a plurality of air treatment system modes of operation.

Abstract
An air treatment system having an improved control system. The control system may include a dynamic “dead front” display that varies the display based on mode of operation. The display may include capacitive touch sensors and include an array of capacitive film segments or traces integrated into the display. The control system may include a self-contained electronics module that can be tested and calibrated before installation in the ATS. A dust sensor assembly may be integrated into the electronics module. The front cover may be attached with a mechanical attachment at the top and a magnetic attachment on the bottom. The ATS may include a filter retainer assembly with a rotating clip configured to perform in a cam-like manner to firmly clamp the particulate filter and carbon filter in place.
