FILTERS

Air filters come in many different sizes, styles and types. The most common is the flat panel filter, consisting of fibrous material in a metal frame. Often the filter media is folded into pockets to add greater media area. Others range from metal honeycomb types for commercial cooking hoods up to the extremely high efficiency HEPA/Absolute type used in operating theatres..

GREASE FILTERS


MANUFACTURED AT AIRFLOW ENGINEERING CHRISTCHURCH

The Airflo Grease Filter is a light weight washable panel unit especially designed for use in cooking exhaust systems. As acids present in the trapped greases of kitchen exhausts corrode ordinary steel, Airflo filters are constructed of acid-resistant aluminum throughout.

CONSTRUCTION
Filter Frame:
Robust 2.0mm Aluminium Extruded Frame, Riveted Construction
Filter Core
: Aluminium Foil Crimped to Honeycomb Pattern
Handles
: Stainless Steel Handles 

The filter media consists of a 50mm thick honeycomb of specially corrugated light gauge aluminium sheet enclosed in an aluminium frame. This 50mm wide aluminium foil strip is formed into a system of double compound curves so that when folded back on itself it forms a non-nesting system of smooth walled honeycombs.

PERFORMANCE DATA
The Airflo Grease Filter will perform with face velocities from 1.78m/s to 2.54m/s, with an average efficiency of 90% at rated capacity. 50mm deep filters have a clean resistance of 20Pa at rated capacity.

MAINTENANCE / SERVICE
Grease filters must be cleaned regularly to minimise the possibility of collected grease dropping back in semi-liquid form off the filter. Cleaners containing caustic must not be used as they will attack the aluminum from which the unit is made.

 INSTALLATION
The filter must always be installed with it face at not more than 30° from the vertical to minimise the possibility of grease dripping off the filter face. Because of the “lay’ of the media in the frame, they must always be installed with the handles on the vertical sides. Under no circumstances must the filter be installed with the handles side horizontal.
