About this item
  • PRODUCT FEATURES calimaero RKKI works well in square meter 95mm. Use sealing tape or sealing band for a tight fit on hoses and vents. This well-made backdraught plastic is weatherproof and UV resistant. It prevents the exhaust air from flowing back and cold air from flowing in. The flaps automatically open when the fan blows out the exhaust air and closes when the air flow stops.
  • INSTALLATION The backdraft shutter is pushed completely into the exhaust pipe. Easy to install and perfect for retrofitting bathroom fans and ventilation systems without a back draft shutter. The flaps must be aligned horizontally in order to close optimally.
  • VERSATILE USE No need to buy multiple products to find the one that works. Applicable in all supply and exhaust air systems, such as air conditioning systems, tumble dryers, extractor fan, cooker hood and other HVAC applications.
  • PERFORMANCE Ideal choice for improving any ducting system without a backdraft shutter. The smooth-running flaps can also be opened by small fans. It does the job and works great for your home improvement.
  • CUSTOMER SERVICE We are experts in ventilation for more than 40 years. If you have any questions or complaints, please contact our customer service directly. Your request will be processed immediately.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
