In the field of industrial and laboratory ventilation, accurate calculations are essential to ensure safety, energy efficiency, and regulatory compliance. That's why SEAT Ventilation provides its customers and partners with a suite of free calculation tools, designed to facilitate the sizing and optimisation of your ventilation systems.
Calculators tailored to your daily needs
Whether you are a design office, laboratory manager or installer, our online calculators support you in your projects by offering you fast and reliable answers. Each tool has been developed to address specific technical challenges encountered in the field.
Laboratory fume cupboard flow calculator
The sizing of a laboratory fume hood requires the precise determination of the required air flow. Our calculator takes into account essential parameters such as the fume hood sash opening area and the desired face velocity to ensure effective containment of vapours and chemicals. An indispensable tool to ensure user safety and compliance with EN 14175 standards.

Plume height calculator
The evacuation of effluents on the roof requires special attention to avoid any risk of recirculation of pollutants to the fresh air intakes. Our plume height calculator help estimates the effective height at which the releases will disperse into the atmosphere, taking into account the ejection rate, the flow rate and the weather conditions. This is an essential parameter for optimising exhaust stack positioning.

Duct Pressure Loss Calculator
The sizing of an aeraulic network involves accurately calculating pressure drops, whether linear (due to friction in the ducts) or singular (bends, connections, cross-section changes). Our calculator uses Darcy-Weisbach equations and K-factors to provide you with a reliable estimate of the pressure losses in your plant. This data is essential to select the right fan and optimize the system's energy consumption.
