There is an increasing need to maintain and improve hygiene standards and reduce fire hazards within kitchens. The baffle grease filter accomplishes both needs through its clever design of interlocking baffles that provide a tortuous route for the passage of air through the filter by creating two rapid 180° air direction changes simultaneously.
The grease molecules having a far greater inertial force than air, impact themselves on the vanes. A series of vertical stainless steel vanes are housed in a channel frame, with each of the baffles strategically aligned to provide the highest potential for grease removal.
Due to the smooth nature of the vanes the grease naturally runs downwards, through the drainage holes and into the collecting trays normally provided within the canopy holding casings. The filters comply with the requirements of DW.172. Approved to DIN18869-5.
Pleated Panel Filters
Used in HVAC systems where an increased level of protection is required and filtration for higher air volume systems. Construction includes: water resistant card frame with lattice faces containing pleated polyester filter media reinforced with an expanded metal support grid. Typical applications: HVAC of offices, retail shops & centres, education, leisure, restaurants, kitchens, hotels and residential Homes.
Synthetic Bag Filters
Used in HVAC systems where high dust holding, high protection, long service life and low pressure drop is required. Construction includes: corrosion resistant galvanised header frame holding dual stage polypropylene synthetic melt-blown filter media, with ultrasonically welded pockets. Typical applications: HVAC of offices, retail shops & centres, education, leisure, restaurant, kitchens, hotels, residential homes, computer rooms and laboratories.
For axial fans the concept of a propeller is applied. The flow through the impeller with the (propeller) blade is largely parallel to the rotor shaft, thus, the name axial fans. The rotating blade has a complex profile to achieve highest efficiency. Basically, the operating principle can be discribed like this: the air on the suction side flows constantly from all parts of the room to the inlet. Thus the inlet ring acts as a suction head.On the delivery side the air is ejected along the axis, effected by by the motion of the fan blades, pushing the air through the fan. Axial fans are mainly used for low pressure and larger air volumes. Ventilation, heating and cooling are thus the main application areas.
With centrifugal fans, it is usual for the direction of the air flow to change by an angle of 90 degrees. Free running impellers and scroll fans differ in that scroll fans require a volute casing to generate pressure. Centrifugal fans are used for higher pressures and medium air volume flows. They are also used in ducted applications. Centrifugal fans provide great versatility in ventilation, cooling and air conditioning applications.
Controllers for fans
Alongside the ventilation range of products there is an extensive range of control technology available, used to regulate the speed of fans. Through fan speed regulation, the air flow delivered by the fan is controlled. The whole purpose of fan speed control is to achieve optimal air quality levels – for example in occupied rooms or for industrial processes. Ziehl-Abegg develops and produces controllers utilising different methods of speed control. This variety of fan speed control methods enables Ziehl-Abegg to offer fan speed control solutions which are accurately aligned with the preferences and demands of discerning customers.
