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 machines 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 extremely low sound 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.

Duct connections

The LTR-5 Z is available with a right-handed duct connection layout.

The LTR-5 Z unit can be installed either with the hatch upwards or to the side. When installing the unit with the hatch to the side, it can be placed on either side. The hatch can be used hinged or can be lifted off the unit during maintenance. It is not allowed to install the unit with the hatch downwards or standing upright with the duct connections vertically.
