LALAGO Ventilation Grille with Automatic Backflow Flap Diameter 100 mm

• 【Disposable Passage】: Two semicircular deflectors open and close automatically, leaving only one way switch, so that the air flow can only circulate in one direction, preventing the air from returning to the air ducts, resulting in backflow and effectively ensuring one-sided air circulation.
• 【One Direction Air Flow Preventer】: When the internal pressure is less than the external pressure, no air flow is allowed to pass through and the air flap closes automatically, which effectively prevents the ingress of outside noise, birds, rats, rain and insects. The baffle must be aligned horizontally to close optimally.
• 【Rubber Seal】The internal rubber seal ring can not only provide a better seal for the operation of the check valve, but also reduce the noise well during use and make the check valve durable.
• 【Easy to install】: when installing the check valve, it should be pushed into the ventilation pipe so that it moves as far as possible. If the valve flap is installed horizontally, the spring should be positioned horizontally so that the flap can open and close optimally. The same applies to vertical installation.
• 【Wide range of applications】: The flap is designed for use in all supply and exhaust systems such as air conditioners, dryers, cooker hoods and ventilation systems. This check valve can be inserted into flexible or non-flexible vent ducts.
