Flexible couplers are used to eliminate vibrations transmited from the fan of other ventilation devices to the ventilation system, as well as to compensate to some extant the ventilation ducts resulting from temperaturę elongation. It is used in ventilation devices in temperatures ranging from -40oC to +80oC.
IO PRO silencer
The IO PRO silencer – damper is a useful and easy-to-install component for ventilation systems in the ventilation accessories category. It performs the functions of pressure regulation and sound attenuation. The damper is made of high-quality polyurethane foam and can be installed in both new and existing ventilation systems. Multiple dampers can be installed to maximise sound attenuation. Installation guidelines must be followed to ensure proper function.
Product characteristics:
The Brookvent IO PRO attenuator is an uncomplicated and easy-to-install ventilation system component that performs two functions: pressure regulation and acoustic attenuation. The IO PRO attenuator is designed for use in circular spiro ducts with a diameter of 125 mm. Thanks to its open cell structure and the high density polyurethane foam from which it is made, the attenuator has a particular ability to absorb sound. The damper-silencer IO PRO acts as a very effective and simple damper at different, even high, air pressure levels in the ducts.
Operating principle and installation:
The air flow and the amount of pressure drop is adjusted by closing or opening the through holes. The IO PRO silencer also has a measuring hole for measuring the air flow in the duct. To increase the attenuating properties, it is permissible to mount several dampers in series – one behind the other.
Construction of the IO PRO silencer:
The product is made of high-quality polyurethane foam, characterised by excellent damping properties. There is the option of installing several dampers in succession to achieve maximum attenuation efficiency. In addition to the through holes, the damper also has a control hole for measuring the air flow in the duct.
