Regel-air® FORTE ventilation system for high air volumes

The Regel-air® FORTE ventilation system combines one pair each of manually infinitely adjustable slide vents Regel-air® SL and window rebate vents Regel-air® FFL units with automatic airflow control.

As an automatic ventilation system, the window rebate vents ensures the necessary minimum air exchange at all times. The slide vent SL can be operated as required. With the FORTE ventilation system, air intake takes place entirely at the top of the window. Using the Regel-air® FORTE, over 20 m³/h of air can be transported per window sash without opening the window. Even when used in conjunction with extract ventilation systems, the Regel-air® FORTE ventilation system is ideally suited to high air flow rates.

Reducing energy costs in the long term

Lower humidity = lower heating costs! Ventilation using Regel-air® window rebate vents reduces the relative humidity in the flat.

This has been proven to reduce heating costs. It also prevents mould growth and improves indoor air quality.
