Description:
|
(1) - Environmental contaminant control or testing.
(2) - Systems for use in residences, commercial establishments, institutions and industrial areas to improve the quality of the environment and conserve energy, namely toxic contaminant control, odorous contaminant control, and corrosive contaminant control, through the use of combinations of components designed into each system for specific air volumes, performances, and efficiencies against toxic, corrosive, and odorous gasses, the components of which may include particulate air filters, gas phase filters, face and by-pass dampers, opposed blade or parallel dampers, humidifiers, de-humidifiers, controls, heating or cooling coils, gauges, fans, louvres, roll filters, diffuser plates, insulation, clamping mechanisms securing filter assemblies against sealing gaskets in air ventilating, heating or filtration systems to preclude the by-pass of contaminants, chemical combinations.
