Are pop up vents effective?

While they have strong circulation systems, some with a comparable CFM to a range hood, pop-up vents just don't have the advantage of surface area and physics on their side to capture the same amount of smoke, steam, and food particles.

Which Ventilation Works Best?

There are many factors to consider when choosing between a range hood or a downdraft vent, but it ultimately gets down to your household’s cooking habits. For regular meals, without a lot of open flame or flying grease, downdraft vents are quiet and efficient solutions. They are designed to work with smaller kitchens, or multi-level homes or apartments where extensive duct can’t be used to vent the fumes outdoors. In commercial or professional kitchens, you’ll find a range hood. In those arenas, the design considerations come second to the performance of the vent. Downdraft vents are not designed to work with heavier, more demanding cooking projects, like indoor grilling. While they have strong circulation systems, some with a comparable CFM to a range hood, pop-up vents just don't have the advantage of surface area and physics on their side to capture the same amount of smoke, steam, and food particles. Because of their placement, behind the stovetop where they pull air across the burners, downdraft vents that create too much airflow could extinguish the flames of a gas stovetop, or cool the pans and play havoc with the cooking temperatures. This places obvious limits on the capabilities of the pop-up vent, as opposed to a range hood which is installed much further from the flame source and can catch everything that rises. Where a range hood can work with physics and collect the hot air that rises, filter it, and expel heat out of the house, a downdraft has to work against the natural air flow to pull that hot air sideways, at an angle and down through the ductwork to pull it from the working area. This can limit the power to do more than siphon, and the pop-up vent can get overwhelmed with too much smoke, steam, or grease. Many installations work best with a blower installed in the ductwork to help move the air out. However, where a downdraft vent excels is in providing ventilation in those homes where it’s not possible to duct through the ceiling or wall. Instead, downdrafts can be routed through the floor, or along the underside of the kitchen cabinetry. Some models have recirculation kits that can filter the air to remove the fumes, with no external exhaust vent necessary. Even those vents that pull the air down through the stovetop help keep cooking smells and moisture out of the air, making life a little easier for the home chef. They provide alternatives to homes that otherwise would have limited or no ventilation, and they can complement overhead ventilation systems that could use a little extra help in more demanding kitchens.

What is a honeycomb vent?

hollandshielding.com - Honeycomb ventilation panels - Holland Shielding Systems

Honeycomb vents are used to shield openings for ventilation or acoustic/visual contact. We can make these vents according to your drawing within a few days, or you can use our standard range from stock. We can supply Honeycomb vents with frames, pre-drilled with fasteners, or with flow-drilled thread holes. The standard material is aluminium which can be given a nickel finish (or any other finish you choose). If high shielding levels are required, the use of cross-cell honeycombs is recommended. These are constructed from multiple sections of 6.35 mm or 12.7 mm or 26.3 mm thick honeycombs within a single frame. The shielding performance will improve as airflow is decreased, but not eliminated. For military applications we make a heavy hot-dip galvanized mild-steel version. Please contact us for more information. Honeycombs are also frequently used as flow straighteners to create a laminar flow.
