Waldner Low Flow
Lab Space Solutions
A laboratory fume hood (also known as a fume cupboard or fume closet) protects the people who work in laboratories with its safe ventilation. It helps to prevent the release of substances harmful to health into the environment and acts as a safe barrier between humans and experimental set-ups. We strive to advance these standards, optimising the airflow rate and saving up to 33 % energy, thanks to Secuflow technology.
A laboratory fume hood from Waldner also impresses with innovative optional functions, including height adjustment, intelligent details, and digital connectivity. Waldner offers the right fume hood for every application, whether you require a bench-mounted fume hood or a walk-in fume hood, have specific requirements governing the internal lining, or require an explosion-proof design.
Ensuring stringent safety in laboratories is paramount. Waldner's lab fume hoods are meticulously engineered to minimize the risk of backflows from the interior of the chemical fume hood, thereby avoiding the escape of harmful substances. Their aerodynamic design enhances airflow, ensuring smooth air movement and reducing turbulence.
Supportive flow air is directed over the airfoil cills, avoiding turbulence and effectively flushing harmful gases away from side walls and work surfaces. The Secuflow fume hood maintains outstanding retention values, even with densely packed equipment in the interior or significant activity in front of it. Its performance surpasses the standards set by DIN EN 14175 and ASHRAE 110, providing reliable protection for laboratory personnel.
To make your fume hood and laboratory even safer, we have developed various safety features. They protect the people in the laboratory as well as the experimental set-up inside the fume cupboard. We offer the following options:
In the pharmaceutical industry, work often involves particulate matter and aerosols. Electrostatic charges near surfaces can cause particles to adhere and be transferred via clothing and equipment. Waldner's IONIC technology employs high-voltage electrodes to ionize the supportive flows, discharging the particulate matter and aerosols, enabling safe flushing by the laboratory fume hood.
A motion sensor on the laboratory fume hood detects whether a person is working at the fume hood. If not, the fume hood automatically closes the open sash. This increases safety and maximises energy efficiency, as the required extract air volume can be reduced to a minimum.
A light barrier monitors the automatic sash-closing process. If an obstacle projects from the internal workspace or a hand is detected within the light barrier's sensing area, the closing process stops. This feature prevents damage to the experimental setup.
The front sash and, optionally, the horizontal sashes are continuously monitored. If the lab fume hood detects that a sash remains open, it emits both visual and audible alarms.
Cameras and temperature sensors can be used to remotely monitor laboratory experiment setups. In critical situations, an alarm can be transmitted to the building management system, enabling continuous monitoring of processes within the laboratory fume cupboard.
Fume hoods designed for special applications with high thermal loads and/or exposure to acids must meet stringent requirements in accordance with DIN EN 14175-7. In specific models, we have adapted the airflow design to ensure laminar flow and safe extraction, even when working with high heat sources (e.g., hot plates). The use of specialized chemical fume hoods and appropriate materials also enables safe handling of perchloric and hydrofluoric acids.
