Base plate with a PP connector
Base plate with a connector (optional). An element closing the bottom of the roof base equipped with a 100, 125, 160, 200 or 250mm-diameter connector.
-
The BRF 125 airtight backflow prevention damper is installed inside the ventilation duct. It effectively prevents undesirable backflow of air.
-
BRF Magneto magnetic backdraught shutter has been designed to be mounted inside 125mm diameter round ventilation ducts to prevent the return of ventilated air. The product stops the ingress of external air at extractor hoods.
-
BZZ backflow prevention device
The BZZ damper prevents uncontrolled air flow in the opposite direction when the ventilation system is switched off.
-
CAR backflow prevention device
A CAR, airtight backflow prevention device, is used in ventilation systems fitted for round ventilation ducts. It prevents the so-called air backflow and protects rooms against cooling in the winter.
-
CFDM fire dampers are diaphragms in ducted ventilation systems that prevent the spread of fire and products of combustion from one fire segment to another by closing the air duct at points of fire separation structures. The damper diaphragm automatically closes the air duct with a closing spring.

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.
-
The KKB damper is designed to automatically cut off the air supply during a fan outage.
-
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.
-
NovaAir anti-smog filter for wall vents.
-
A flat-roof base is made of a galvanised sheet. Two types of roof bases are available:
- PDI — insulated with is a 10mm insulation (polyurethane foam) inside preventing condensation and
- PDT — silencing, with 50mm insulation (mineral wool).
The collar around the base allows the base to be firmly attached to the roof.
-
Adaptation frame for installation with BMV PRO fan, if PDI/T roof base can’t be installed.
-
TLE flexible acoustic silencers
A flexible TLE acoustic silencer is made of a perforated duct. The applied insulation is 25mm thick and covered with an aluminium-polyester jacket. The silencer is connected with metal flanges acting as a nipple. These are available in two lengths, 600mm and 1,200mm. Upon request, it is possible to manufacture silencers: with EPDM
-
The TLS silencer is used in round ventilation ducts. As a standard, the silencers are delivered with a rubber seal. Inside they are filled with 50 mm thick mineral wool.
