1 TPI 2-06

The present Technical Specifications determine sizes, properties, scope of application, and final manufacture of fat filters. The Specifications apply to the design, ordering, production, acceptance,delivery, and use of these products as of 1.11.2006. The present technical specifications replace TPI 2-04.

I. GENERALFat filters serve for air exhaust in the kitchen ventilation system and damp premises in the range of temperatures from 0Cup to 70C. They are designed to be mounted onto the duct, into the spigot or into the wall. The function of the fat filterlies in capturing of finer fat aerosol particles from the exhausted air. They also can be provided with an air flow regulator.Fat filters IMOS - OT are delivered:

- OTV - vertical mesh - more layer metal filter for vertical installation- LOT - vertical with a two level filtration - more layer metal filter with a labyrinth-type filter- OTH - horizontal mesh - more layer metal filter for horizontal installation

Functionality Description

Fig. 3 Vertical fat filter with a two level filtration

Fat filters are designed as terminal elements for exhausting polluted air in performances, where the exhausted air containsvapour, fat and other grease. They are being mounted onto the exhaust duct, where they separate impurities from the air.The separator frame is fixed to the duct, as for OTH the separated grease is captured in an intercepting container, as forOTV in an intercepting drain. The standard position of the intercepting drain is a = 90C, if necessary, the a angle can beoptional. It is easy to pull out and wash the separator collet (pic.6). Two level fat filters are designed for environments withhigher vapour concentration.The OT separability depends on the composition of the polluted air and the exhaust velocity. Recommended velocities areshown in graphs 1 and 2.

Maintenance of IMOS - OTV, OTH and LOT :Apart from common cleaning, it is not necessary to perform any maintenance during the operating life of the fat filter.

Cleaning:It is possible to clean the fat filter collet in a dishwasher or manually. We recommend to use a detergent for stainless dishes. The recommended washing temperature in a dishwasher is up to 60C, when cleaning manually the collet has tobe soaked in warm detergent water of ca. 50C and cleaned with a brush after 15 minutes.
