Information supply air systems
Feed aisle ventilation
The feed aisle ventilation is a simple type of air supply, but it requires a sure instinct and experience.
Slot ventilation
Ceiling supply air elements made of hard-wearing hard foam plastic panels with manual slide valve on the underside (DZE 1) or with 2 pull-wire actuating flaps (DZE 2).
Jet ventilation
With jet ventilation, the cold supply air is z. For example, taken from the attic and let in parallel to the ceiling. Due to the so-called Coanda effect, the cold supply air leans against the ceiling and is guided up to 10m. During this time, this mixes with the warm air in the barn and a vortex arises in the animal area.
Trickle channels and diffuse ceiling
Areas of application for the trapezoidal ventilation ceiling are large-scale stable buildings and compartments with insulated roof cladding. The perforated panels are fastened directly under the ceiling, 2 layers of mineral wool are placed between the binders, one layer with a laminated fleece surface. The fresh air supplied from the roof space is distributed over the entire supply air ceiling and reaches the animal area evenly. The mineral wool prevents the warm stable air from penetrating back into the roof space. The laminated surface slows the absorption of moisture by the mineral wool, for example when washing the compartments.
Nasal ventilation
Nasal vents are mainly used in farrowing compartments. In most cases, a combination of trickle cover and nasal ventilation pipes is used. In winter, the air flows out of the trickle cover and in summer, nasal ventilation pipes, which end about 1.2m above the crevices, are also opened. The fresh air flows directly to where it is needed, to the sow's head. The piglets do not come into contact with the cold supply air.

Wandzuluftelemente ZEW
Wandzuluftelement
ZEW 1500
- with straight flap for installation in the wall
- with 50 mm wide flange for neatly covering the wall duct
- infinitely variable control via pull (automatically closing) or reduction (automatically opening) with central servomotor and rope possible
- A sealing lip is integrated in the frame.
Wandzuluftelement
ZEW 1500 M
Difference to the ZEW 1500:
- When fully opened, the curved flap directs up to a maximum of 35% of the inflowing air directly downwards
- from the maximum degree of opening,
- which can be set using an adjustable bearing pin in the hinge plate. The flap opens automatically.
Wandzuluftelement
ZEW 2500
- particularly hard, resistant polyurethane
- optimal cleaning and hygiene thanks to smooth surfaces
- approx. 5 cm wide panel for easy wall installation
Wandzuluftelement
ZEW 2500 M
- particularly hard, resistant polyurethane
- optimal cleaning and hygiene thanks to smooth surfaces
- approx. 5 cm wide panel for easy installation in the wall,
- maximum opening of 35% can be adjusted by means of an adjustable bearing pin in the hinge plate.
- The flap opens automatically.
Wandzuluftelement
ZEW 5000
- Supplement to the supply air system of the trapezoidal ventilation ceiling
- No high air velocities at high air rates with trapezoidal-sized supply air valves as a supplement to compensate for this.
- The air velocity increases and thus the desired cooling effect
- loss-free inflow of fresh air approx.
- A 50 mm wide frame around the valve makes installation easier
Supply air wall flap ZWK
The new ZWK 1 supply air wall flap is controlled by a cable pull and is used for outside feeding aisles.
The number of elements as well as the distance from the wall and the width of the ceiling slot depend on the required volume flow and the length of the section.
This efficient and reliable supply air system is characterized by problem-free installation and low maintenance requirements.
Supply air distributor
Supply air distributor with circulating air fan
The supply air distributor with circulating air fan was designed in order to better supply stables with fresh air.
This is particularly important for stables with structural restrictions in order to provide an optimal and inexpensive fresh air supply.
Ventilation ceilings | Giant channels | Perforated ventilation plates
The perforated ventilation plate made of PVC or plastic-coated EPS core is available in thicknesses of 25mm and 40mm. The outer layer of the perforated inlet plate is available in thicknesses of 0.3mm, 0.7mm and 1mm. On request, it can also be supplied with a GRP cover layer.
