Fibre & Special Felts

Dust removal frond gases is carried out thanks to the use of textile filter media.

The nature and granulometry of the particulate are among the main components to be evaluated when choosing the optimal filter medium.

Thanks to its long and consolidated experience in the industrial field, Testori offers a wide and distinctive range of special felts, with and without scrim, specifically developed to meet the needs of each customer and application.

The appropriate fibre selection, to be chosen from a wide range available, is strongly linked to the final application and process parameters (the main one is the operating temperature at full capacity).

The specificity of the application conditions may also require the application of special treatments to the filter media, which Testori offers in a wide choice.

-	Description	Fibers	Advantages
MICROFIBERS	Use of microfibres (up to 0,9 dtex) on the dust side; Alternatively use of multilobal sectioned shape fibres on the dust side	PES PAN PPS P84	Controlled low emissions; Better efficiency; Increased bag lifetime
DURAtes	Use of microfibers; Increased compactness and needling uniformity	PES	Controlled low emissions; Increased bag lifetime; Energy savings
ANTISTATIC FELTS	Use of epitropic fibres blended with standard ones in the batt to improve conductivity of the finished felt For better performances use of stainless steel fibres in the scrim	PP PES PAN PPS PMIA	Surface resistivity below 104 Ohm
SSB	Stratified structure with pre-oxidized polymer fibers mixed with finer fibers and standard fibers (on the dust side of the felt)	PES	Increased resistance to sparks or other incandescent particles; Longer sleeve durability
BLEND	Use of a special blend of fibers optimized for asphalt production plants	ASPHALT BLEND	Reduced cost of ownership
COLORfelt	New eco-friendly felt for all industries	Nomex 100%	Sustainable; Optimal performance
MULTILAYERS	Multilayer construction with microfiber cap on the outside	PPS-PI PAN-PI	Greater control over emissions; Better efficiency; Longer sleeve Durability

In addition to the more traditional processes of glazing and heat setting, for the felts it is possible to request special surface treatments to give water / oil repellency, resistance to sparks, greater filtering efficiency or antibacterial properties.

-	Description	Fibers	Advantages
ePTFE MEMBRANE	Expanded PTFE membrane coating on the dust side	PES PAN PPS PMIA GLASS PTFE	Controlled low emissions; Better efficiency
KLEENTES	Bath impregnation of the felt with fluorinated resins	PP PES PAN	Water repellency; Better cake release; Suitable for sticky dust
RHYTES	Fluorinated and PTFE resins for deep bath impregnation of the felt	PES PAN PPS PMIA P84®	Water and oil repellency; Better cake release; Suitable for sticky dust
MANTES	PTFE resins for deep bath impregnation of the felt	PAN PPS PMIA P84®	Water and oil repellency; Very good cake release; Increased bag lifetime
NOVATES	Polyurethane foam deep coating; Suitable for continuous operating temperature up to 140°C	PES PAN PMIA	Better filtration efficiency; Very low emissions below 5mg/Nm
RESILTES	Water based silicone finishing	PES	High abrasion and fatigue resistance Tear resistance doubled if compared with not treated felts Unaffected residual pressure drop and cleaning cycle time
EKU	Special deep bath finishing suitable for temperature up to 180°C Protects the filter media by preventing the heat transfer from the spark to the fibre	PES PAN PPS	Increased resistance to sparks or any incandescent particle Increased bag lifetime
AgTes	Antibacterical treatment	PES	Bactericide & bacteriostatic properties Washing resistence
