LOW-FREQUENCY FILTERING MEDIA REPLACEMENT FOR BLOWN FILM AND CAST LINES
BDC and BDCLD filtration housings are designed specifically for blown and cast film lines requiring strong filtration levels. The Static filters BDR have been engineered to be used on extrusion coating lines for application of plastic film coating on a no polymer-based substrates.
Model BDC and BDCLD
BDC and BDCLD filtration housings are designed specifically for blown and cast film lines requiring severe filtration levels.
Single and multi-cartridge (3,7 and 12) BDC are suitable for filtration fineness up to 40 microns by means of cylindrical elements available with different diameters and length in order to achieve an overall filtering area allowing extended working time.
Filtering media surface can be flat or pleated in order to multiply up to 4 times the total filtering area.
BDCLD are suitable for extremely strong filtration levels up to 3 microns by means of disc filtering media “leaf disc” made out of sintered wire cloth laminated or non-woven media.
BDR static filters have been engineered to be used on extrusion coating lines for application of plastic film coating on a non-polymer based substrate.
Available with filtering masses from 60 to 160 mm dia., the plate filter holder is equipped with a mechanical seal which prevents any leakage of polymer during working phases.
Downstream of the filter a needle valve is used to adjust the polymer flow from 5 to 100%.
