KRKW / RSKW
The KRKW / RSKW non-return damper has a tight design according to the ÖN M 6027 standard. The KRKW / RSKW damper blade consists of a frame and of a silicone membrane. The KRKW/ RSKW tight non-return damper is suitable for vertical or horizontal installation. The installation is done by inserting the damper into a duct. The non-return damper has a double-lipped seal for sealing and fixing in the duct.
KPK
The KPK odour-resistant non-return dampers are equipped with a permanent magnet, which ensures the closing of the tight damper when pressure drops. The closing and opening pressure of the damper can be adjusted with a screw. The design of the KPK tight non-return dampers allows a direct insertion into a ventilation duct. The non-return dampers are suitable for kitchen hoods.

MCA
The MCA is a non-return damper for use in conjunction with the MAR, MBR and KTB adapter to create the MIXVENT-TWIN combination. The MCA non-return dampers are made of metal, varnished in the same colour as the TD Mixvent fans. The MCA dampers are mounted directly to the TD Mixvent fans, including seals as direct accessory. The non-return damper blades are made of aluminium.
CAR
VS
VS are negative pressure non-return dampers designed to prevent backflow of air into the ventilated space. They open automatically under negative pressure when the fan is started. The lightweight damper wings are made of thin aluminium sheet. The underpressure dampers have a flange made of galvanized sheet metal. They are mounted from below with screws in the prepared threads, directly on the fan base plate. The VS non-return dampers are designed for use with NK and NDH roof attachments. The pressure drop characteristics of the VS dampers are shown in the charts.

NKTM
The NKTM pressure relief non-return dampers are used for automatic closing of HVAC ducts in case of fan shutdown. The NKTM pressure relief non-return dampers are designed either without rod (design .01) or with rod (design .01T). The NKTM non-return dampers prevent backflow of air in case of shutdown of a fan. The maximum flow speed is 12 m / s and the maximum overpressure in the damper is 1500 Pa.
The NKTM non-return dampers are designed for installation in HVAC ducting or for installation at its end. The pressure relief damper is designed for installation in vertical or horizontal ducts. If installed in horizontal ducts, the axis of damper blades must be horizontal. Damper bodies and blades are made of galvanized sheet metal without further surface treatment. Plain bearings are made of durable flame retardant nylon.
