OLOi-HF exhaust air device

The OLOi-HF is a unit for large volumes of exhaust air which complements the product range of OLO suspended ceiling diffusers. The product has been developed so that even at large air volumes pressure losses and noise levels remain low. OLOi-HF is especially suitable for schools, offices, and shopping malls.

OLOi-HF is particularly suitable for high air volumes, in schools, offices, and shopping centers with a central exhaust air ventilation system or a suspended ceiling system. Thanks to the innovative design, the pressure drop and noise level remain low even at high air volumes.

Suspended ceiling systems often contain a lot of technical devices, so using fewer devices saves space on the ceiling surface. Devices need to be suitable for larger volumes in this situation. One OLOi-HF device matches up to three exhaust air devices designed for smaller air volumes.

OLO collection for a complete entity

OLOi-HF continues the OLO and OLOi suspended ceiling diffusers’ collection. All products in the collection have identical external dimensions, and the simplistic design is replicated in the entire collection, for completing a space. The signature Climecon surface treatment helps to keep the products clean.

Easy installation with front part mobility

Horizontal mobility of the face part is characteristic of the devices in the OLO collection. The feature simplifies the installation phase and improves the finish.

The products are shielded at the factory so that they remain clean until commissioned and no dirt enters the ducts. The protective film can be removed and reattached during installation.

Carbon footprint

The carbon footprint of the products has been calculated as part of the requirements of the Building Information Foundation’s EPD environmental report.
