Advantages
Use imported mono-filament polyamide basketwork as filter media, with the characteristics of high wear strength, long service life and good combined effect.
High dust collection rate, low initial resistance and good dust
-proof performance, filter media can be washed repeatedly.
Use ultra-thin aluminum foil as the frame which can be made into a interlinked group with handle. Replacement of the filter is safe, simple and convenient.
Material Instructions
Media: Adopt mono-filament polyamide basketwork as filter media.
Frame: Ultra-thin aluminum foil as the frame with handle.
Temperature: Maximum 90°C in continuous service.
Application
Suitable as pre-filter in ventilation systems of office buildings, conference rooms, hospitals, shopping malls, recreation centers, airports and other huge civil architecture as well as general factories and clean rooms.
