Air Supply Unit Z-HASP

Air Supply Unit Z-HASP — a compensating air supply system is a key element in a properly designed professional kitchen ventilation system; without adequate air compensation, intensive extraction hood operation creates negative pressure, which can impair kitchen performance, reduce safety and worsen staff comfort; the Z-HASP solution addresses this issue by delivering temperature-treated fresh air directly to the work area in HoReCa businesses.

Negative pressure problem in a professional kitchen

Air Supply Unit Z-HASP — professional kitchen extraction hoods are designed to extract large volumes of air — a typical restaurant hood may handle 1000–5000 m³/h depending on kitchen size and the number of heat-generating appliances; this air must be reintroduced into the kitchen. Consequences of negative pressure — if the air is not compensated, negative air pressure develops in the kitchen compared to adjacent areas; doors become harder to open or close on their own; airflow from the dining area to the kitchen disrupts extraction hood operation; combustion appliances (gas hobs) may not ignite correctly or fail to produce an optimal flame. The solution — an air supply unit Z-HASP delivers fresh outside air directly to the work area or just below the hood, compensating for the extracted air volume; see extraction hoods. BHS supplies air supply units across Europe.

Z-HASP air supply unit operating principle

Air Supply Unit Z-HASP — the Z-HASP system supplies fresh air from outside directly to the kitchen, usually preheating or cooling it to a comfortable temperature to prevent direct introduction of cold or hot outside air. Air introduction point — air is typically introduced just below the extraction hood or at another strategic location where it can effectively compensate for extracted air without creating disruptive airflow towards staff. Heating/cooling treatment — the Z-HASP system often includes a heat exchanger that heats cold outside air in winter before introducing it into the kitchen; this process ensures that staff do not receive cold air directly above them; see Hood with Air Supply HPPD.

Z-HASP and other air supply solutions comparison

Air Supply Unit Z-HASP — several air supply solutions are available for professional kitchens; Z-HASP is a standalone air supply unit that works with any extraction hood, while some hood models have integrated air supply. Integrated air supply — extraction hoods with built-in air supply (such as HPPD or HPCD) combine extraction and compensating air delivery in a single unit; this solution is more compact but may be more complex to install. Standalone Z-HASP — a standalone air supply unit can be installed with any existing extraction hood; it offers greater flexibility; see Island Hood with Air Supply HPCD.

HoReCa application scenarios for Air Supply Unit Z-HASP

Restaurant kitchen with high-volume ventilation — in a large restaurant kitchen with multiple heat sources and large extraction hoods, the Z-HASP system ensures sufficient air compensation, maintaining stable pressure in the kitchen; BHS equipment provides an effective ventilation solution. Corporate canteen with a newly built kitchen — when setting up a new canteen kitchen with professional ventilation, Z-HASP is an essential part of the ventilation project; BHS supplies the products. BHS offers air supply units Z-HASP to HoReCa businesses across Europe.

Frequently asked questions

Is an Air Supply Unit Z-HASP necessary for all professional kitchens? Air Supply Unit Z-HASP — no, the need for air compensation depends on kitchen size, extraction hood capacity and room sealing; in small kitchens with good natural ventilation, a ventilation window or a smaller supply system may suffice; in larger kitchens with powerful extractors, air compensation is usually necessary; see extraction hoods.

Is the Air Supply Unit Z-HASP installed together with an extraction hood? Air Supply Unit Z-HASP — the Z-HASP is usually installed simultaneously with an extraction hood as part of the ventilation system; equipment placement, air duct design and connections are coordinated; involvement of a ventilation specialist is recommended in project planning; see Condensation Hood with Condensation Plates HKCD.
