CARTRIDGE FILTER

CURRENT TECHNOLOGY

WHY USE NANOFIBRES?

Compact filters using the Nanofibres having all the best

factors together:

• Permeability (small pressure drop)

• The best filtering efficiency

• Very small thickness of the layer

• High porosity

• Low basis weight not increase filter media weight

• Small pore size

• High specific surface area

• Submicron particles capture

NEW TECHNOLOGY USING NANOFIBERSchematic of filtering material based on Nanosolution

SpunbondEngineeredpolymeric supportproviding thestiffness, mechanicalstrenght and pleatability for nanofiber layer

Active nanofibrous filtering layer with narrow pore size suitable for submicron filtration

COMPARSION OF PRESENT AND NEW TECHNOLOGY

Filtering medium from Nanofibers magnified 600x – filtration class U17

Filtering medium from Nanofibers magnified 5000x

Filtration material – 100% synthetic spunbonded polyester – E12

Filtration material – cellulose / synthetic fiber paper E12

COMPARSION OF PRESENT AND NEW TECHNOLOGY

Current solution

Cartridge filters filtration class E 121. Static2. With pulse flush

Compact filter class E 12V – paneled filterZ – paneled filter

New Nanosolution

Cartridge filters filtrationclass ULPA 171. Static2. With pulse flush

-Triple layers- hydrophobic and oleophobic nanofibrous prefiltering layer + depth nanofibrous fiter + synthetic substrate - Lower pressure drop. - thanks to much greater active filteration surface, lower pressure drop, and much higher efficiency - MERV 15 and higher

NEW TECHNOLOGY USING NANOFIBRE

Filtration by Cartridge filters with class H12 – U17 and nanofibers

– Static filters with pulse flush

Pre – filter Layer removes large particulates, rejects moisture

High Efficiency Nanofibers layer removes submicron Dust, Water and Salts

Melt – blown offers high Strenght Backer, Provides Burst Strenght

BENEFITS OF NANOSOLUTION FOR FILTERING IN GAS TURBINES

1. Reduce Turbine Wear - (High filtration efficiency (for particulate > 0.3-0.5 micron) reduces fouling on the blade throughout) 2. Optimize Power Output - Eliminates power losses - Low fuel consumption - Low CO2 and NOx emissions3. Reduse salt corrosion 4. Low consumption of the cleaning pressure air for jet pulze cleaning filters
