Air flow rate with inlet fully open (in m3/h) * When using the light trap, all wall inlets of the CL 1200 series have the same reduced air flow rate. ✓I ideal supply of fresh air with negative pressure ventilation; advanced inlet control creates stable air jets, especially with minimum ventilation; 4 strong tension springs close the insulated and non-deformable inlet flap (integrated profile made of aluminium) so the barn is absolutely airtight; exact control of the inlet opening thanks to strong tension springs: stable air circulation all the way to the centre of the barn, uniform...

CL Flex is available in different widths, allowing the realisation of different air rates. Using a counterweight of one kilogram, the inlet opens when it is no longer pulled closed. Thanks to the inlet's optimised geometry and the lateral guide plates, stable air jets create good air circulation in the entire room. During development, special attention was paid to a reliable sealing of the closed inlet. The inlet flap has good aerodynamic properties with a tear-off edge and integrated air guide at the frame, stabilising the air flow further. The inlet's size is flexible so it can easily be...

The perfect accessories for our wall inlets Useful, effective and sometimes indispensable  Protective net against birds This net stops birds and small animals from entering the barn through the inlet. For the CL 1200 series, we offer a selfsupporting plastic net that comes in two different mesh sizes. The net is attached to the outside of the inlet by a simple locking mechanism. For CL Flex inlets, the net is made of galfancoated wire mesh and also attached to the outside of the inlet.  Air deflector With the air deflector, the direction of the air flow can be adjusted individually for...

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. Fresh air enters the barn through the attic. The roof should also be insulated to prevent heat build-up in the summer. The inlet's flap opens through downward pull, which allows controlling the amount of incoming air. The air always...

Balanced pressure inlet CL 1200 Balance For installation into the walls of smaller, narrow barns for free range egg production This special fresh air unit consists of a standard CL 1200 wall inlet, a cowl and a small fan. It is mainly used in barns in which constant negative pressure ventilation cannot be guaranteed, generally smaller houses for free range egg production where using fresh air chimneys would not be practical. The large pop holes make it impossible to create a stable air circulation in such barns. The fresh air is therefore pushed into the barn by a fan, i.e. the ventilation...

Fumus is always equipped with a fan in the lower part of the chimney. This fan pushes the fresh air drawn in by the chimney through the fresh air distributor and into the barn. The amount of air entering the barn is regulated by means of a butterfly valve above the fan. Depending on the position of the butterfly valve, anywhere between 100 percent fresh air (vertical position) and 100 percent recirculated air (horizontal position) enter the barn. Between these positions, a certain amount of fresh air is mixed with the house air, which is drawn in through the 10 cm wide opening at the...

The advantages at a glance 4 ood ventilation of the barn thanks to g the large throwing range, ideal to dry the litter; 4 mixed air creates a constant warm the breeze; 4 erfect for cold weather because the air p flow always guarantees an ideal throwing range, irrespective of the ventilation level (mixed air); 4 fan ensures constant air movement – the the CL 74 actuator controls the position of the butterfly valve and creates fresh air, mixed air or recirculated air as required (recommendation: individual control).

Using a tunnel or CombiTunnel ventilation system requires large air inlets near the gable on both sides of the barn, or directly in the gable. These inlets allow the fresh air to enter the barn on a large surface, displacing the stale air without mixing with it. Constant and high air speeds at bird level (aim: 2 to 3 m/s) lower the temperature perceived by the birds (windchill factor). MultiVent 10 M & 17 M, MultiVent 3, 4 & 5 and SOB 50Inlets for fresh air supply over a large surface Our MultiVent inlets are characterised by a very high air flow rate. They can be used as air inlets for...

Tunnel door with rack and pinion drive (TD-L) For large tunnel openings – robust, well-insulated and airtight Our Big Dutchman tunnel door TD-L consists of either 40 mm or 50 mm thick composite boards with a robust plastic coating. The frame and the rack and pinion are made of corrosion-resistant aluminium. With the EWA actuator, the tunnel doors can be opened and closed steplessly, allowing very exact distribution of the air. The flexible lip seal ensures tight closing with very little closing force. Total door lengths of up to 40 m are possible! TD-L is available with heights of 750,...
