The Enervent LTR-6 unit is best suited for large detached houses or public spaces, like offices.

The LTR-series units are designed for installation in the roof, in the attic, in a false ceiling or in a technical space. The horizontal installation often saves a lot of space. LTR-series units are well insulated and can be installed in cold places. The unit needs additional insulation if the temperature around it drops below -10°C.

The simple but ingenious structure and the low pressure drop of the unit ensure an inexpensive and safe operation.

Duct connections

The LTR-6 is available with a right-handed duct connection layout.
