Fresh air supply systems
Optimum fresh air supply for every type of poultry production

Wall inlets are well-suited for use in poultry houses. The CL 1200 inlet is designed to beembedded in thick

wall structures, such as brick, while the flange inlets CL 1211 F and CL 1200 B/F are especially suited

for thin walls which use material such as insulated aluminium panel.

This type of inlet consists of recyclable, shock-proof, non-deformable, UV-stabilized plastic and can easily

be cleaned with a pressure washer. The insulated inlet flap is kept in a closed position by means of

rust-proof steel springs which seal the building airtight. The inlet flap can be opened by downward pull.

This allows the producer to precisely regulate the inlet opening during each season. The cold fresh air

enters the barn from above and mixes with warm house air before it reaches the birds.

By means of the corresponding control set, the fresh air inlets can either be opened all at once or individually.

Thanks to the patented differentiation, the producer can select by means of a simple adjustment on each

inlet which inlets are to be opened first and which inlets are to be opened later. If the number of opened

inlets is reduced, especially during the cold ceason or during the heating period, the remaining

inlets can be opened farther which makes for more stable airflows.
