Guide and selection support
Ventilators are used in laboratories for the targeted movement and redirection of air or other gases, often for ventilation, cooling, or air conditioning. The choice of the right model depends on the required airflow, pressure ratio, and installation situation. LabFinder provides guidance through the choice of products and delivers clear information to support the precise procurement of ventilators tailored to laboratory-specific requirements.
Applications and Benefits
Ventilators are used to move gaseous media in laboratory environments. They generate airflow with a typical pressure ratio between 1 and 1.3, enabling ventilation, cooling, or air circulation. Common applications include climate control of devices and workspaces, support of exhaust systems, and improvement of laboratory air quality.
Selection Criteria
Important selection factors for suitable ventilators include the required flow rate, pressure ratio, installation space, as well as noise level and power consumption. Axial and radial ventilators are distinguished by their flow principle and performance requirements. Compatibility with existing laboratory infrastructure can also be a deciding factor.
Types and Measurement Principles
Ventilators are mainly divided into axial and radial types. Axial ventilators move air parallel to the axis of the impeller, making them suitable for high volume flows at low pressures. Radial ventilators move the medium perpendicular to the impeller axis, can achieve higher pressure ratios, and are generally more compact. Selection should be based on pressure and flow rate requirements.
Calibration and Maintenance
Ventilators do not require calibration in the conventional sense. Regular maintenance includes inspection of the impellers, bearings, and housings, cleaning of any contamination, and checking of electrical drives. Faulty components can reduce airflow performance and should be replaced in a timely manner.
Application Limits
The use of ventilators is limited to operation with gaseous media. For pressure ratios greater than 1.3, compressors are used. Ventilators are not suitable for handling aggressive or explosive gases unless they have been specifically designed for such applications.

Frequently asked questions
How does a ventilator work in the laboratory?
A ventilator moves gaseous media using a rotating impeller arranged either axially or radially. This creates a low pressure ratio to generate airflow within the laboratory.
What types of ventilators are used in laboratories?
The main distinction is between axial ventilators, which move air parallel to the axis, and radial ventilators, which move air perpendicular to the axis and generate higher pressures.
What should be considered when selecting a laboratory ventilator?
Key selection criteria include the required air volume, pressure ratio, installation location, noise level, and energy efficiency of the device.
How should a ventilator be maintained in the laboratory?
Maintenance includes cleaning the impeller and housing, inspecting and lubricating bearings, and checking electrical components.
What are the limitations of using ventilators in laboratories?
Ventilators are suitable only for low pressure ratios and are not appropriate for aggressive or explosive gases unless specifically designed for such use.
