Ventilators

Ventilators are meant for objects of high cubic capacity. By forcing air circulation they reduce heat loss generated by air stratification in a room. They are made of stainless steel or glass – polyester laminate.

Additionally, vent casing is equipped with undersling grip. Various vent diameters are adjusted to cubic cubature and needs.

Controllers of rotational speed SPA are microprocessor devices used for regulating the power of asynchronous motors. The devices enable control engine revolution from complete switch off to total switch on.
