H-line by Unovent — Horizontal through-wall ventilation
Description

H-line is a horizontal heat recovery ventilation system that is installed through an exterior wall. This means that roof space is not required for ventilation making H-line perfect for apartments, townhouses, sleepouts and anywhere that roof space is limited.

H-line features an EC motor with a ceramic core; this qualifies H-line as continuous extract or balanced ventilation depending on the setting chosen. On medium air flow H-line achieves the required air changes for a 27m² space at 2.4m stud height. One to two H-lines can provide the balanced ventilation required for most living rooms while only one is typically needed for bedrooms.
