SINBRAN® filter modules combine the advantages of membrane filtration technology with those of the rigid body filtration. Almost no loss of pressure with high filtration performance combining great mechanical stability and a long service life.
The inside of the filter modules contain a sintered air-permeable polyethylene tube and the outside is covered with an ePTFE membrane.
The special lamination process combines high air permeability with good filtration performance and greater mechanical stability of the combination of supporting tube and membrane. The laminated tubes are then assembled into the individual filter modules.
The manufacturing parameter are set to combine the tubes high mechanical stability and a low resistivity for the air flow.
The process parameters for the lamination are set to provide optimum permeability, separation and stability for the laminate.
The design of the flange was adapted to fit already available filter units. We offer different types of gasket to suit all application areas. The filter modules are made from PE, stainless steel and a small percentage of PTFE. We do not use glue, solvents, pottings or other substances during the manufacturing process.
A fan draws dusty air onto the surface of the SINBRAN® filter module. The dust is then separated by the membrane surface of the filter module and the clean air will pass through the sintered material of the rigid body to the clean gas side. The separate functions of the two filter material components ensure a clean separation and no dust will get into the sintered material. Due to this principle the sintered rigid body is free from dust and the filter material can keep its function with a low differential pressure over a long period of time.
An air pressure impulse initiates the cleaning of the filter modules. An over pressure from the inside sends a vibration to the membrane and the dust flakes of the smooth surface of the membrane and falls into the dust collection facility. This separation effect is supported by reverse air stream which flows opposite to the filtration air stream.
The main body and the flange of a SINBRAN® filter module are made of sintered polyethylene. The flange is reinforced with a stainless steel bar and fitted with a silicone or EPDM gasket for an airtight seal. The membrane material is made from high quality ePTFE (expanded polytetrafluorethylene). The properties of polyethylene define the application areas of our filter modules.
- Properties of PE:Temperature resistance from −85 °C to +90 °C. For the filter elements the temperature is limited to 70°C.
- Stability in most polar solvents (T < 60 °C),acids, bases, alcohol, oil
- Not soluble at room temperature and some solubility at higher temperatures for non-polar solvents e. g 1,2,4-trichloro benzene, xylene oder in hexane
