There are many arrangements possible using Spring Air Systems KES Enviro Units. Figure 10
above outlines some of the most common installation arrangements. Consideration must be
made when a fire rated enclosure is required for the NFPA-96 exhaust ductwork. The KES-ISH
filter box is UL/ULC listed but it is still considered an extension of the NFPA-96 exhaust ductwork.
Generally, when the KES-ISH filter box is located in the same fire rated compartment as the
exhaust hood and exhaust ductwork no fire rated enclosure is required. But, the local authorities
having jurisdiction must be consulted for every application as requirements change from
municipality to municipality.
