Our products are available in both self-contained stand alone units and in-duct models that are installed directly into your central HVAC system. Whether a small bedroom or a large sewage treatment plant, our products range in application from a 100 sq. ft. to several hundred thousand sq. ft. and everything in between. Most models are in stock and can be pulled off the shelf and some projects require engineering a custom solution. Either way, we have the right product for your application.
