The Enervent LTR-5 Z is suitable for single-family homes, terraced houses and commercial premises. The LTR series units can be installed on roofs, attics, ceilings or technical rooms. Horizontal installation often saves a lot of space. The LTR series units are well insulated and can be installed in cold places. The ventilation unit requires additional insulation if the ambient temperature drops below -10 ° C.

The simple yet ingenious design of the air handling unit and the low pressure drop ensure low cost, safety and very low noise levels. The LTR-5 Z’s hatch can be used as a hinged or detachable hatch. The swing cover is interchangeable to meet the requirements of the installation site.
