Carbon Types
The absorption ability of activated carbon is due to the enormous surface area to volume ratio of the material. (Typically 1000 sq metres per gram)

Grades of carbon equivalent to 203c and 207c are available from stock. Special carbon can also be provided to suit specific requirements

Sometimes it helps to impregnate the carbon with catalysts or reactants specific to the contamination. These agents are spread over the entire area producing a huge reaction interface

Bonding
Ace Filtration activated carbon filters are manufactured from graded carbon granules chemically bonded to form uniform biscuit panels. This provides even air resistance across the face of the panel preventing settlement and air bypass. Panels are cloth covered, making them clean to handle

Carbon Filters
Carbon panels, ACD filters or ACR filters are available in standard and non standard sizes. ACD denotes a disposable filter, containing carbon panels in deep 'Vee' formation and bonded within a galvanised sheet steel case. ACR denotes a filter case containing replaceable framed carbon panels in a deep 'Vee' formation

Pre Filters
Carbon removes odours by physical absorption. Accumulation of dirt or grease on the carbon face will cause blinding of its open pore structure and reduce the performance

It is essential to provide a pre filter to protect the carbon. This would normally be a G4 bag as a minimum, but if space is limited we suggest a carbon pre filter type ASPC. This is a 75mm thick panel comprising of a 2" pleat element plus a 1" synthetic pad

Kitchen Extract
In kitchen extract applications where grease is present, a grease filter must be fitted before the pre filter. All pre filters should be checked and replaced if necessary. Every effort should be made to prevent grease and smoke particles from reaching the carbon filter. The carbon filter should be fitted as far as possible from the extract inlet. This helps to cool the air and hence improve the performance

Process Extract
Refer to Absorption Ability data on separate sheet.

Side Access Casings
Casings to house ACD filters are available for single or multiple filter applications. Slides for pre filters are included as standard. Construction is of galvanised sheet steel, with angle supports and flanges each end.

Jacking bolts are provided to ensure the carbon filters seal positively and prevent air by pass.

Type ACR do not require casings since they can be incorporated into ductwork using slip joints

How to Order
Tell us the flow rate, the application and any size limitations.

Ace Filtration can quickly select a suitable filter either from our standard range, or design a special to suit your needs. Special delivery times are no longer than standard filters.
