Ventilation chimneys ![]()
Exhaust air chimneys - characteristics
Suitable for all types of livestock houses to create a friendly climate for the animals
Available chimney diameters Ø 630mm, 820mm, 910mm
UV radiation, gases, frost and corrosion resistant
Very easy and quick to install
Performance
Efficient exhaust air flow thanks to:
- inlet ring with the shape extending to the sides which increases the air flow up to 10% and the efficiency of the fan
- diffuser - very high, with shape extending upwards, which increases airflow by 15% and fan efficiency
The aerodynamic shape of these elements increases airflow - it is sucked in and ventilated much more efficiently at nominal energy use. This increases the efficiency of the fans, saving up to 15%-20% of energy use
Installation
Chimneys perfectly adapt to the roof pitch thanks to the roofing plate made of:
- flat, glass-fibre-reinforced plate, impact-resistant
- waterproofing membrane - EPDM roofing foil - high quality, UV-stabilized rubber, which easily adapts to any roofing pitch and roofing profile, is resistant to tearing and has a minimum 20 years of service life
The materials of which the roofing panels are made are fully waterproof, resistant to low (-30°C) and high (+120°C) temperatures and UV rays
Chimneys with roofing panel
The chimney adapts perfectly to the roof pitch thanks to the joint and roofing plate adjustment
The joint is assembled at the factory, so it is perfectly tight and the water does not leak
Chimneys with roofing foil
The chimney adapts perfectly to the roof thanks to the foil made of rubber, waterproofing HYDROGUM - EPDM membrane, which is tear-resistant and has a guaranteed 20 years life
The chimneys are supplied with all components necessary to install the rubber foil to the roof
Diffuser
The diffuser increase the airflow by 15% and additionally its shape and height:
- lowers noise levels
- makes easier to remove odors thanks to a constant speed of maximum air stream
In the chimney of diameter fi 630 the dimensions of the diffuser are: height 730mm, width at the base 175mm, width at the top 930mm
In chimney of diameter fi 820 the dimensions of the diffuser are: height 940mm, width at the base 880mm, width at the top 1150mm
In chimney of diameter fi 910 the dimensions of the diffuser are: height 940mm, width at the base 1000mm, width at the top 1260mm
Cover flaps
Consists of two flaps made of reinforced composite material resistant to wind blows and with weatherproof stainless steel fixings
Two independent weights, for each one of the valve flaps, allow for the regulation of flap falling speed
The closed cover flaps tightly stops sunlight and rainwater which flows down through the gaps between the diffuser and the chimney tube
Chimney extension
For all chimneys diameters are available extensions of 0.6m or 1.2m long
The upper part of the extension is sanded down to a cone, which makes it easier to assemble with chimney tube
Very easy installation of the extension to the chimney with the screws and nuts included in the kit
Technical specifications
Made of high quality polypropylene plateswith thickness:
- 4mm for chimneys fi 630
- 5mm for chimneys fi 820
- 6mm for chimneys fi 910 in black color prevent sunlight penetrating
Chimneys are delivered in parts, what reduces transport costs
Screws and nuts necessary for installation included in each one chimney
Fresh air chimneys - characteristics
Thermally-insulated, with a diameter of 650mm, always equipped with a fan that blows air from the outside and distributes it evenly throughout the building, thanks to a mixer suspended at the chimney outlet
The standard chimney is 1m high, but can be extended by additional extensions 1m or 0.5m
Mounted to the roof with a roofing plate (product code 4220) or roofing rubber foil (product code 4221)
Construction
The chimney consists of:
- rain hoods with protecting net
- roofing plate (product code: 4220) or roofing rubber foil (product code: 4221) with mounting kit (screws, nuts, washers, strips and bands)
- 4 hangers for suspension
- ceiling cover
- air mixer/distributor
- transparent electrical box for actuator mounting
Fresh air chimney fans

Accessories
Water collecting basins for suspension below the air duct
Available of dimensions:
- fi 906mm (Product code: 4150-35)
- fi 1350mm (Product code: 4150-36)
Main advantages:
- protection against rainwater which could penetrate through the chimney
- shading - protect from the sunlight
Made of high quality plastic, resistant for aggressive livestock house environment
Chimney shutter fi 630
In addition, chimneys fi 630 can be equipped with chimney shutter with electrically opening flap instead of inlet ring
The shutter tightly covers the chimney inlet prevent from of cold outside air entering and limiting the loss of warm air
It is equipped with a hermetic electrical box designed to mount an actuator for automatic opening and closing the flap of valve
Product code: 4150-08
Deltafan chimney fans
Into the exhaust chimney is possible to mount - high quality and low energy use - Deltafan chimney fans
Easy installation of the fans in the chimney is possible thanks to a special band and support arms, which ensure stability
Low-running motors (900 rpm) working with a lower noise level
Adapted for control by external controllers
