SlyHE Sly High Efficiency Felt (micro pore sized fibers) designed for fine pollutants. Microfibers are a great solution to fine, uniform, free-flowing dust and fine solids in liquid process slurries. Combinations of finish and felts with SlyHE are capable of emissions below 1mg/m³ or .0004 grains/ft³. Our high efficiency felts are available in both regular and high temperature (Aramid) applications.
SlyHe vs. Commodity Felts – Because fiber surface area and separation efficiency are directly related, SlyHE concept felts are capable of providing as much as ten times the efficiency of conventional felts used in general filtration applications. This capability is a result of ultra-fine fibers commonly known as “microfibers”. The SlyHE felts use a proprietary blend that includes a high percentage of micro-denier (<1.0 denier) fibers, thereby significantly increasing surface area and reducing pore size openings resulting in a high efficiency felt, while the weight remains the same. Within the SlyHE concept, any fiber or combination of fibers can be used to create an ultra-high efficiency felt.
Some advantages of SlyHE felts over commodity felts:
- Higher filtration efficiency due to a surface orientated filtration
- Extremely low emissions rates
- Extended bag life by reduced cleaning intervals
SlyHE vs. Membranes – Since the performance of the SlyHE felts are based on the total felt design, including a micro-denier fiber blend and heavy duty scrim, they have significant advantages over the PTFE membrane laminated felts that rely on the fragile micro-thin lamination.
Advantages of SlyHE felts over PTFE membrane laminates include:
- High efficiency without a fragile membrane laminate
- Strong and durable
- Able to handle oily, fatty, moist or abrasive dusts
- Can handle Alcohol compounds
- Uniform and consistent
- No special installation required
- Cost effective
Some examples of successful applications include; carbon black; Resin coated silica sand; color pigments; barite and calcium carbonate.
- Available SlyHE felts: polypropylene, polyester, homopolymer acrylic, Nomex®
