Metallic & Non-Metallic Dusts: Filtration Options
Oil Mist
In this design the collected oil mist passes through a series of filter elements, the oil droplet size progressively reducing until the required level of filtration is achieved. Circuit manometers are normally incorporated in the final stages of filtration to indicate filter status and whether filter cleaning or replacement is required. Adequate filter capacity needs to be specified at the design stage in order to ensure the diffusion velocity across the filter membranes is sufficiently low in order to achieve a high level of filtration.
Electrostatic
In this design filtration of the oil mist is achieved by passing it through an ionising chamber where individual oil droplets are charged to a high positive potential. Positively charged oil mist then passes into a second chamber where a collection plate charged to a high negative potential attracts the positively charged oil drops which then adhere to it and as a result are removed from the airflow. Most designs incorporate arrestor plates and mechanical filters up stream of the ionising chamber to ensure filtration efficiency remains high by reducing the average droplet size entering the ionising chamber. Effectiveness of filtration is dependent on maintaining the correct airflow through the filter and to ensure adequate time for the ionising charge to build up on the oil mist droplets and the regular cleaning of the collection plate.
Mobile Filter Units
In applications where process fume may be generated in a number of different areas mobile filters provide a cost effective alternative to fixed installations. We can supply models utilizing both electrostatic, self cleaning and mechanical filtration methods in a full range of supply voltages and collection arm formats. Typical units;- MFC 1200 - Mechanical Mobile One - Self cleaning Luggable Units - Smaller hobby type applications
Wet Collectors
A wet collector comprises of a housing having a primary separator for removing relatively heavy particulate material from a contaminated gas stream. This is achieved by means of centrifugal force and a secondary separator. This includes a hollow cylindrical scrubbing element having a circular wall formed of a plurality of restricted passages for removing the remaining particulate material from the gas stream. Liquid is discharged into the secondary separator and is distributed over the wall of the scrubbing element by the moving gas stream.
Multi Dust Bank
A modular self-cleaning cartridge collector with the markets most efficient cleaning system gives outstanding filter life. The modular design makes it possible to tailor-make systems depending on application condition. Made for heavy applications usage.
Mechanical Filter
Mechanical filter for welding fumes and other dry dust. The modular design gives flexibility to expand or tailor-make your system. Normally utilized for light duty or maintenance applications.
