Trilogy Fume Hoods are designed to provide maximum personal protection at an economical cost by operating at a low velocity and reducing exhaust volume. The LOC Trilogy hood functions at an exhaust volume of less than half of a conventional hood. Not only does it save you money by reducing the volume of air that needs to be conditioned and exhausted, it reduces the size of the HVAC equipment saving on the original capital investment, making you highly efficient from start to finish. The Trilogy hood provides three essential components: high performance, energy savings and safety.
The static pressures listed above are for the hoods only. An appropriate amount will need to be added to this figure to compensate for the pressure drop through the duct system. The total pressure drop through the hood and the duct system must be known to select the proper exhaust blower.
