Carbon Filter Unit

£850.00 £1,050.00

Applications

Activated Carbon Panel Filters are normally supplied fitted with an aluminium frame and can be made to any reasonable size to match existing panels of all makes.

The depth of the bonded carbon panel filter is restricted by our own imposed limits of not less than 10mm and not greater than 60mm Actual depth.

Capacities shown for Activated Carbon Panels & Activated Carbon Discarb Cells are based on a dwell time of 0.1 seconds, which is the normally accepted minimum for most applications.

Description

For heavier odours i.e. Indian or Thai cooking odours, a contact time of 0.3 seconds with the carbon filter is recommended to ensure effective odour control, which will effectively reduce the Face Velocity and rating to one third.

Where hot air is being filtered (e.g. extract from cooker hoods) the activated carbon panels or discarb cells should be positioned as far from the heat source as possible, so not to comprimise effective odour removal.

Air stream temperatures in excess of 40°C should not be exceeded. If temperatures in excess of this figure are anticipated, reduce the air temperature by means of a fresh air bleed or a cooling coil.

Humidity levels must be maintained below 80%RH for air passing through the activated carbon panel. Again this can be acheived by mixing with dry air or conditioning the airstream.

Pre-filters should be fitted in the ventilation system to protect activated carbon filters, to protect the carbon filters and ensure a good life for the filter. We do not consider a glass panel to be suitable and recommend a filter having a minimum grade of F5 to EN779, such as a general purpose multi pocket filter.

Some cooking operations give off large amounts of smoke, which is extremely detrimental if allowed to reach the carbon filters( smoke is a particulate). (See HEPA Filters, or Electrostatic Precipitators for smoke control)

Grade 20 Activated Carbon Filters are rated 30% on their ability to adsorb carbon tetrachloride (CTC) in testing; and have a typical surface area per weight of between 700-800 m2/g by the BET N2 method (the area being a measure of the area of the walls of the cavern like structure of the activated carbon): Bulk density is between 0.55 - 0.59 g/cc

 Grade 50 Activated Carbon Filters are rated 55% on their ability to adsorb carbon tetrachloride (CTC) in testing; have a typical surface area per weight of between 1100-1200 m2/g by the BET N2 method (the area being a measure of the area of the walls of the cavern like structure of the activated carbon): Bulk density is between 0.49 - 0.53 g/cc

Pleated Panel Air Filter - G4 to EN779:2012- Disposable Panel Air Filter

- Rigid Cardboard Frame Construction

- Food Safe Air Filter

- Extended Surface

- Large Dust Holding Capacity

- Energy Efficient

- Available in Metal Facia Capscrap or Cardboard Lattice

- Metal Framed Pleated Panel Filter available for high humidity applications.

Applications

The Pleated Panel Air Filter is a medium efficiency disposable air filter, suitable for ventilation and air conditioning systems which require a higher efficiency and greater dust holding capacity than can be achieved with glass or synthetic panels.

The G4 Pleated Panel Air Filter can be used where glass panels are undesirable, such as in the food industry and hospitals.

Typically G4 Pleated Panel Air Filters are used as pre filters on supply air systems to High Performance Bag Filters, or to protect heating or cooling coils from dust build up which leads to system in efficiency. Another common place to see G4 Pleated Panel Air Filters is to protect fans in extract systems for office blocks or kitchen extract systems.

Description

Pleated Panel Air Filters consist of a dry non-woven fabric media which is pleated to give an extended surface area, producing a low initial resistance for the same air volume, making this an energy efficient air filter.

The pleated air filter media is contained within the air filter by a rigid all cardboard casing, or a cardboard frame with recycled perforated cap-punch retaining grids. The filter is sealed together using hot melt adhesive glues to ensure a highly rigid and quality disposable panel air filter.

The Pleated Panel Air Filter is available sealed into a galvanised steel metal frame for high humidity applications such as supply air from atomosphere where standard cardboard filters may loose their rigidity and fail.

Technical

The pleated air filter media is Flame Retardant to DIN53438

Max Operating Temp 100 Deg C

Dust Holding Capacity for 50mm Filter = 840 g/m2

Dust Holding Capacity for 100mm Filter = 1260 g/m2

Recommended Face Velocity 2.5m/s

Nominal to Actual Size: less 6mm on H & W, 3mm on Depth
