Products and services

GYPSUM CIRCLE DIFFUSERS

As with all Ventmann products, the CIRCLE series diffusers can be plastered flush with the wall or ceiling and painted seamlessly to match the surrounding surface. All standard CIRCLE models can be customized to your requirements:
• Diameters of 100 mm or 125 mm – the smallest standard connection sizes available.
• Diameter of 160 mm – the medium standard connection size.
• Diameters of 200 mm or 250 mm – the largest standard connection sizes offered.
Heavy-duty magnets hold the diffuser cover in place—these magnets retain their strength for up to 95 years.
This is our most versatile unit, fitting the design of most rooms while delivering comfortable airflow in virtually any application. Like all frameless diffusers, the CIRCLE can be used for both supply and exhaust air.
Finally, you can install multiple elegant CIRCLE diffusers in a single-occupancy room for an even air distribution and a unified aesthetic.

GYPSUM SQUARE DIFFUSERS

Square-shaped ventilation outlets SQUARE are far more than ordinary air diffusers. They serve as minimalist design elements that highlight the crisp lines and sharp angles of modern interiors. Say goodbye to bulky grilles—you’ll never have to conceal your ventilation again, because these outlets become an integral part of your inner decoration.

GYPSUM LINE DIFFUSERS

The LINE series ventilation outlets offer an elegant, versatile solution for interior design. With this model, you can create striking, one-of-a-kind design elements or, conversely, render the air diffuser virtually invisible.

GYPSUM SIDE DIFFUSERS

The unique design of the SIDE series diffusers ensures uniform air distribution across the flat surface on which they’re mounted. These side-mounted duct diffusers also serve as attractive interior design elements.
Their interchangeable covers offer both circular and square formats, providing a highly practical solution.
No matter which model you choose, you’ll enjoy all the benefits of Ventmann’s gypsum diffusers:
