The Purair SKY has a dynamic filtration chamber with a sliding filter clamp that allows for simple, quick filter changes. Units come with an epoxy coated steel support frame with LED lighting and wall mounted controls. An electrostatic pre-filter helps trap additional contaminants and increase filter life.   
   
Purair SKY units are available with an optional SKY Controller with open source BACnet™ networking protocol for seamless integration with a multitude of building automation and supervisory controls, including alarm and monitoring functions.
