Heat and steam hood without filters Novameta HNPDC-70-70-48

A heat and fume hood extracts warm, moist air rising from hot appliances before it spreads across the kitchen ceiling. Instead of relying on filters to trap grease, this type of hood draws the air directly into a duct system, pulling steam and heat away from the work area. The process keeps humidity levels lower, reduces condensation on surfaces, and prevents the build-up of stale, warm air that can make a kitchen feel oppressive. Because there are no filters to clog, the airflow remains consistent, and the system requires less frequent maintenance than grease-filtering models. The hood is positioned directly above the source of steam or heat, creating a column of rising air that the exhaust collar captures and directs outside the building.

The operator fits the hood over the appliance, aligning the exhaust collar with the ductwork. Once the ventilation system is switched on, the hood begins drawing air upwards as soon as the appliance below generates heat or steam. There are no settings to adjust on the hood itself; the extraction rate is controlled by the external fan and ducting system, which a ventilation specialist calculates and installs. The hood remains in place during service, continuously removing warm, moist air without interrupting the workflow. After use, the hood does not require daily intervention, though the ductwork and fan will need periodic checks to ensure the system maintains its designed airflow.

Constructed from AISI 304 stainless steel, the hood resists corrosion and withstands the high humidity and temperature fluctuations common in professional kitchens. The smooth surface allows for quick wiping, reducing the time needed for cleaning. An optional powder-coated finish or decorative panels can be added for a more tailored appearance. The hood meets HACCP standards, ensuring it supports food safety and hygiene protocols in commercial environments.

The controls available for this model include an optional IP65-rated LED lighting unit and a light switch, both of which can be fitted to improve visibility under the hood. The 315 mm exhaust collar provides a connection point for the ductwork, determining the volume of air the system can extract. The hood's dimensions—700 mm in length, 700 mm in width, and 480 mm in height—define the space it occupies above the appliance, influencing where it can be installed and how much clearance is needed around it.

Cleaning involves wiping the stainless steel surface with a damp cloth and mild detergent to remove any surface moisture or residue. The absence of filters eliminates the need for filter washing or replacement, though the ductwork and fan should be inspected and cleaned according to the ventilation system's maintenance schedule.

This model is available in multiple widths, ranging from 800 mm to 1300 mm, with each size increase reflecting a proportional adjustment in the overall dimensions. The hood is designed for use above dishwashing areas, combi ovens, and steam cabinets, where high humidity and heat are prevalent but grease particles are minimal.
