Wall Hood with Filters HNPD

The HNPD wall hood is a specialised ventilation solution designed for installation on the wall directly above thermal processing equipment such as hob surfaces, ovens, fryers and other heat-emitting appliances in the kitchen. The hood effectively collects steam, oil particles and odours, directing them through the ventilation duct outside the room. Effective kitchen ventilation is a mandatory requirement for both workplace safety and HACCP food safety standards.

Advantages of wall mounting

The wall hood is mounted directly on the kitchen wall rather than suspended from the ceiling above the kitchen island. Wall mounting is more suitable for kitchens with equipment arranged along the walls and for spaces with low ceiling height. Installation is usually simpler and more economical than ceiling hood installation, as no complex ceiling brackets or scaffold systems are required. A wall-mounted hood is structurally stable and maintains its position even under vibration.

Metal oil filters in the HNPD model

The metal oil filters in the HNPD model capture oil particles and heavier particles in the airflow before they enter the ventilation duct. The filters are washable and reusable; they should be cleaned regularly in a dishwasher or with degreasing agents. Clean filters ensure optimal hood performance and reduce the risk of fire that can result from oil accumulation in ventilation ducts. Regular filter cleaning is the main element of preventive maintenance.

Hood power and efficiency

The power of a professional hood is measured in cubic metres per hour; the greater the heat and steam output from the equipment, the more powerful the hood required. A correctly powered hood ensures that steam is fully captured and does not enter the surrounding space or adjacent rooms. Insufficient hood power leads to the accumulation of unpleasant odours, increased humidity and the deposition of oil particles on ceilings and walls. When choosing a hood, it is important to consult on the required air exchange volume for the specific kitchen.

HACCP requirements for kitchen ventilation

Standards require that air quality in professional kitchens be controlled: steam and oil particles must not accumulate in the work area, as they can become a source of contamination for food. Regular cleaning of the hood’s filters and interior is a mandatory part of the HACCP maintenance plan. The cleaning schedule and records must be documented. The Food and Veterinary Service checks the compliance of ventilation systems in restaurants and food production facilities.

Choosing the hood size

The length of the wall hood must match the total length of the thermal processing equipment it serves. It is recommended that the hood extend beyond the equipment block by at least 200 mm on each side, which improves steam collection from the edges of the equipment. The installation height of the hood above the equipment is usually 1900–2100 mm from the floor, depending on the room’s parameters. BHS helps kitchens calculate and select the correct hood parameters.

Ventilation duct and air circulation

For effective hood operation, the ventilation duct must have sufficient capacity. The duct diameter must match the hood’s airflow volume. Long or frequently bent ducts reduce airflow, so their number should be minimised during the design phase. If an external ventilation duct is not possible, some models offer a recirculation option with carbon filters. Air supply to the kitchen must be ensured by a supply system to prevent pressure imbalance.

Advantages of stainless steel

AISI 304 stainless steel is the standard material for professional kitchen hoods. It withstands high temperatures, resists corrosion in humid conditions and is easily disinfected with standard cleaning agents. The stainless steel surface does not promote bacterial growth, which is important for complying with HACCP requirements in food processing areas.

Selection based on kitchen format

Different thermal processing equipment produces varying amounts of steam and oil. Fryers and grills require a more powerful hood than induction hob surfaces or convection ovens. For café kitchens with small-scale food preparation, a compact HNPD model is sufficient. Restaurants with an extensive menu, including fried and grilled dishes, need a more powerful model with a larger filter area. BHS provides advice on selecting the appropriate model.

Frequently asked questions

How often should the oil filters in the HNPD hood be cleaned?

In a busy kitchen, once a week or more frequently. In less busy kitchens, once every two weeks. BHS provides maintenance advice.

Is the HNPD suitable for small kitchens?

Yes, wall mounting is ideal for compact kitchens. Various length options are available to match the equipment layout. BHS helps with selection.

Installation and maintenance

Installing a wall hood involves creating wall mounts, connecting to the ventilation duct and electrical supply. Installation should be entrusted to a certified specialist to ensure proper ventilation capacity and safe electrical installation. Regular maintenance includes cleaning the filters, washing the hood interior of oil deposits and checking motor parameters. Contact BHS for a quote on purchasing the HNPD wall hood.

Energy efficiency

Modern professional kitchen hoods are equipped with energy-efficient motors that reduce electricity consumption during daily operation. Regularly cleaned filters ensure optimal airflow with minimal motor load; clogged filters increase energy consumption and reduce hood efficiency. Some models feature multi-stage speed control, with a lower speed used during periods of lower load. BHS provides information on the efficiency parameters of available HNPD models.
