Filter Fan Unit Aseptic (Food)

Germ- free environment in the food industry

Point protection concept. Ortners Aseptic FFUs open up new possibilities in the areas of safety and shelf life for companies in the food industry. The FFUs create a particle- and germ-free environment, making them suitable as a punctual protection concept for particularly critical areas.

Surface disinfection with UVc technology. In addition to the filtration of particles and germs via HEPA filters, the integrated UVc surface disinfection ensures sustainable microbiological stability and very long filter service lives.

The germ- free air is blown in directly near the product and creates a microclimate around hazardous production areas. Aseptic FFUs are pure recirculating air units. In addition to providing selective protection, they also help to improve indoor air quality. With the optional cooling coil equipment, the flow behavior can be significantly improved.

 A gray cube tilted upwards with one edge looking forward. On the bottom is a grid. On the right side of the cube is a small blue bar that says "ortner" and below that "cleanrooms unlimited". On the left side of the cube is a small blue bar on the right that says "Aseptic FFU". On this side is a depression in the form of fan blades. The cube becomes wider towards the top. At the top edge is a grid.
 From the upper right corner of the picture, a conveyor belt goes to the left to the center. Below that is a conveyor belt that comes from the back left, curves eight and goes back to the back right. On it lie many small sausages. In front of it stands a woman in white clothes with an apron and a protective hood in blue. On the right side of the picture is a man with shoes, pants and coat in white, a protective hood in blue and a clipboard in his left hand.
Safe ambient climate for people and product
 On the lower right side of the picture is a large yellow tub with a yellow liquid. Next to it stands a man with clothes and a cap in white. In his hands he holds a long rod at the end of which at the top, left and right is a round curved narrow plate. The plates are connected with thin bent rods. In the background are tiled walls and pipes.

On a conveyor belt coming from the top right, making a turn to the bottom right, are many small cakes completely covered in chocolate.
Optimized indoor air quality throughout the processing area

As Surface Mounted Unit or Freely Installed

The Aseptic Filter Fan Units can be used as surface-mounted units on production and filling lines or as freely installed clean air modules.
