This air filter was designed and developed for purpose of removing air pollutants and therefore providing good and healthy indoor air in residential buildings. Air contamination is defined as various size particle matters (PM) like smog, fine dust, soot, fungal spores, pollen, viruses or bacteria. This filter effectiveness is classified according to EN ISO 16890. This is an electrostatic precipitator which uses electrical current and electromagnetic phenomena. We recommend the airflow at 575 m3/h at most to reach best performance, regarding both filtering efficiency and low pressure drop

A window reveal module for the decentralised heat recovery units - HRU-WALL series. The module is intended for installation in the facade, in the insulation layer, a ventilation grille is mounted on the window reaveal. The window reveal module provides practically invisiable solution for supply/extract ducting. This method of installation will be especially useful during the thermal modernization of the building. The product has a universal layout, the choice of "right-sided" or "left-sided" assembly is made at the construction site. In addition, a slope for possible condensation growth was implemented into the design.The duct is telescopic, which means that the distance from the axis of the HRU to the window reveal can be adjusted in the range of 380-490 mm.

Do You know that You can join PVC vent pipes using special glue? To be precise You can glue ventilation pipes and fittings up to a diameter of 250mm. Glueing is a popular method of joining PVC ventilation systems because it's rather simple and requires no special tools as in the case of extrusion welding or wire welding (see How-to: Welding plastic ventilation ductwork). However, in order to make a solid and tight joint of PVC pipes and fittings, we must properly prepare the duct components for the process of glueing and follow the recommendations of the special glue manufacturer. Find out How to properly glue PVC ducts and fittings - Read our Manual!

The DM-ML / DM-FL actuator enables remote operation of a ventilation damper. The actuators with 5, 6 and 8 Nm of torque are the most popular choice for ventilation dampers. The torque of 6 Nm allows opening dampers with the crosssectional surface area up to 1.5 m2; they can be installed on ventilator dampers up to 400 mm in diameter. The DM-ML -...- S actuator has an additional limit switches, which can signal the damper position in the range of 0-10-80-90. Precise, variable control of damper position is obtained by mounting the DM-ML -...- RS actuator, which operates by means of current signal 0 (4) -20mA or voltage signal 0 (2) -10V.
