The ball protection grilles are used as supply or extract air grilles in gymnastics, sports and multipurpose halls. They are protected against ball impacts, i.e. all models have been tested by the official Research and Material Testing Institute for Civil Engineering (Otto Graf-Institut) in Stuttgart, Germany. Tests passed for footballs, handballs and medicine balls.

The continuous diffusion grilles can be used as supply or exhaust air grilles and look very attractive. They can be inserted in ceilings or walls and integrate themselves in any kind of rooms.

The esthetically neat grille is estimated for exhaust and circulating air. A wall-opening can inconspicuously be covered with a DG 13 grille at max. free area, volume flow rate respectively. The DG 13 grilles are also suitable as relief air grilles.

Diffusion grille with individually adjustable vertical and horizontal laminae (as DG 1). With an additional damper consisting of an inclined flap casing of light metal with tiltable front lid. The deflecting vanes of the flap guarantee constant uniform distribution of air over the entire grille surface.

The attractive light metal diffusion grilles ideally complement sophisticated construction elements.
The light metal diffusion grilles can be used as supply or exhaust air grilles. The various types we manufacture provide an optimum solution for every application problem.

The diffusion grilles are used as air supply or exhaust grilles in visible ducts.
They are suitable for industrial plants, shopping centers, warehouses, etc.
Due to the different types and sizes available, an optimum solution is ensured for each individual application.

Diffusion grille with automatic temperature-dependent air stream deflection.
For energy-saving supply air systems in halls for (e.g. exhibitions, workshops, multi-purposes, warehouses etc.) where, apart from an effective distribution of air and the elimination of thermal stratification, great importance is attached to comfort in the working area at any point within the plant.

Diffusion grille which directs the jet of air according to the temperature.
For energy-saving supply air systems in halls for (e.g. exhibitions, workshops, multi-purposes, warehouses etc.) where, apart from an effective distribution of air and the elimination of thermal stratification, great importance is attached to comfort in the working area at any point within the plant.

Diffusion grilles of stainless steel DGX conserve their good aspect for years, do not require any surface protection, and are not charged with static electricity. They are used wherever hygienic and aesthetic requirements are given high priority.

The diffusion grilles do not incorporate any additional dampers. Hence, they are designed mainly for use as individual grille.

The diffusion grilles are suitable for systems which require subtile flow-rate regulation, as is the case when several grilles are connected to the same pressure duct. The direction of air discharge is not influenced by the vertical countercurrent flaps.

Air supply grille specially designed for industrial systems with high-velocity ducts. In combination with the baffle plate, the tilt-down closure panel provides good flow-rate control and uniform air distribution to both grille halves.

The well-designed screen grilles are made of colorless anodised alumium sections. Other colors on request.

Bypass grille with stable, V-shaped louvers. The design chosen ensures perfect screening. May be installed in walls, doors etc.
