Filter Mesh Test Stand

Filter Mesh Test Stand

Skype / Email

Filter mesh test stand is based on relevant standards and specification to test quality control factors: pipe leakage, dust generation, flow test, resistance test, the change of different filters, flow control.
 · Power section
· Aerosol generator section
  The aerosol generator can consecutive produce stable DEHS particles (particle size range 0.3-3μm) .
· Particle counter section
  The sampling flow of the particle counter is 2.83L/min. The particle counter is specially suitable for particle size 0.3μm-10μm.
· Fixture and structure section
    The pipeline is made of 305 stainless steel, anticorrosion and antirust, with consideration  of convenient pipeline replacement ( when testing different size of filters).
· Flow monitoring section: Using V cone flowmeter for flow detection.
· Differential pressure monitoring section:
Using imported DWYER electronic differential pressure transducer for pressure measurement.
· Flow control section
   Electric control valve to automatically regulate the flow
· Data processing:
   Including PLC, software and electric control
