Verified compatibility with RECUBOX® units

We have thoroughly tested these fans in combination with RECUBOX® heat recovery units. They excel in high performance, ability to overcome pressure losses and low electricity consumption.

Regulation and integration

Like other EC fans, they are infinitely variable in the range of 0-100% using a 0-10 V signal (for example from a REX EC controller). They can be integrated into a smart home using a suitable control module.

Sound properties - comparison with VENTS VK EC

DOSPEL BLDC fans are slightly noisier than VENTS VK EC and their impellers are not as precisely balanced.

Recommendation: For bedrooms, children's rooms or wherever quiet operation is important, we recommend VENTS VK EC fans.
