  2. Ecology unit filters last up to 10 times longer than in conventional systems
  3. No additional energy input, agents or sprays required
  4. Low maintenance saves thousands of dollars annually for the operator
  5. Compact, efficient design saves on installation costs and expensive kitchen space
  6. Standard models up to 10,000 cfm, larger custom sizes available
  7. Oil Screen filters provide additional protection against sparks and fires
The ECO.NF-series Oil Screen Kitchen Exhaust Filter Module is a high performance multi-stage, independent grease extraction duct module without fan and is ideal for food court kitchen applications where all kitchen exhausts are ducted to a central exhaust fan. They are also suitable for stand-alone installations with a separate third-party exhaust fan. Each system is packaged with the high-performance Oil Screen filter, particulate and smoke filters, and optional odour absorbing filters, achieving a maximum level of pollution abatement. The ECO.NF-series kitchen exhaust filter module is tested in accordance with ULC S647 and must be installed in accordance with NFPA96, CSA and all applicable national and electrical codes.
Heat, smoke, steam, oil and grease particles are drawn through the kitchen hood by the separate central (or third-party) exhaust fan and ducted to the ECO.NF exhaust filter module, which extracts the contaminants with an efficiency of up to 99% on particles as small as 0.3 micron. The initial filtration stage consists of Oil Screen filters which provide a highly efficient filtration of the liquid grease & oil particles preventing these liquid contaminants from entering the smoke and odour filters. In doing this, several benefits are realized:
  • the disposable smoke filter stages last longer
  • maintenance frequency & costs are reduced
  • exhaust air flow remains constant
  • offensive odours normally generated by grease-clogged filters are prevented
Odours remaining after the high-efficiency final smoke filter stage are less concentrated and offensive. Odour reduction can be achieved using less-expensive carbon or potassium-permanganate filters without the need for large media beds or odour spray systems.
The resulting clean air passes into the central exhaust system or to the other exhaust fan.
A separate control panel is provided to monitor filter presence and filter condition.
Installation Clean exhaust air with an acceptable amount of odours removed can be discharged to the outside through the side of a building or adjacent to higher structures, thus saving costly runs of heavy-gauge welded exhaust ducts to the roof level.
  • Can be located in a mechanical room, hung in a ceiling space or placed outdoors.
  • Flanged connection provided on both inlet and outlet for ease of field duct connection.
  • Low-profile and custom sizes available for tight installations and easy handling.
Components
  • Filter Section- consists of Oil Screen filters, secondary multi-stage smoke filters and optional odour abatement filter.
  • Unit Controls- filter sensors monitor clogged filter and missing filter conditions. Upon sensing missing filter, sensor shuts down fan and activates appliance interlock output.
  • Control Panel- ON/OFF switch; indicator LED’s for clogged filter and missing filter status.
Oil Screen ECO filter systems are installed in a variety of sensitive high-demand properties:
