Gypsum frameless diffusers Ventmann

Designing modern and energy-efficient buildings equipped with air conditioning systems presents a significant challenge for architects and designers. It is crucial to find solutions that harmoniously connect the aesthetic aspects of the interior with the functionality of the air conditioning systems. In response to this need, Ventmann introduced an innovative design solution in the form of plaster and frameless diffusers. These products are designed to minimally disrupt the aesthetic quality of interiors, providing architects and investors with greater flexibility in their creative concepts. Plaster, which is the primary material of the Ventmann diffusers visible in the interior, is an eco-friendly material. Due to its adaptability, plaster diffusers can be plastered, sanded, and painted in accordance with other surfaces, allowing for their almost perfect integration into the interior design. Despite their high aesthetic value, Ventmann diffusers maintain significant functionality necessary for effective air distribution. Thanks to a patented design that utilizes plaster material, these elegant diffusers can integrate into various types of ceilings and walls made of drywall. Ventmann diffusers feature compact mounting boxes, which allows for a reduction in the height of the ceilings while providing the option to design spaces with higher ceilings.

The most versatile and popular model is the round diffuser Circle, which fits perfectly into a wide range of interior styles. The Circle model is available in two variants:

• CIRCLE Classic, ideal for air exhaust.
• CIRCLE Coanda, designed for air supply with modified edges of the valve that direct the air flow along the ceiling, thus preventing drafts. This model is also suitable for air exhaust.

The linear diffuser, model Line, offers extensive creative potential, allowing for the creation of unique interior elements or its almost complete concealment.


The diffuser consists of an acoustic box and the diffuser itself, which can be connected to the Air Excellent air distribution system or traditional round Spiro ducting using adapters. Diffusers are available in lengths of 0.625, 1, and 1.25 meters with 1, 2, or 3 slots. They can be installed individually or connected into a continuous line, providing maximum flexibility in design.
