Air inlet for livestock buildings CL 1540

ceilingfor ventilation

Fresh air inlet for installation in a ceiling below the attic The ceiling inlet CL 1540 is made of a recyclable, shock-proof, non-deformable and UV-stabilised plastic material. It should be installed into a ceiling that has been insulated, if possible. Even with a ceiling inclination of up to 15 degrees, CL 1540 will close reliably. This is guaranteed by rust-proof steel springs that keep the insulated inlet flap closed. Main advantages -ideal supply of fresh air from the attic with negative pressure ventilation; -very versatile; -advanced inlet control creates stable air jets, especially with minimum ventilation; -strong tension springs close the insulated inlet flap so the barn is absolutely airtight; -exact control of the inlet opening thanks to tension springs: stable air circulation all the way to the centre of the barn, uniform temperatures while heating requirements remain low; -because the air “sticks” to the ceiling, the negative pressure required even for large throwing ranges is low;
