Description

The base body of the HSL-C filter, which was developed in-house and is protected by patents, differs from the  standard Herding^® sinter-plate filter in that it is made of thermostabilized sintered polyethylene (PE). Deposition of the product on the surface - classical surface filtration - is achieved by means of a moisture-repellent PTFE coating which is embedded in the pores of the PE base body and forms a microporous surface.

• The coating of PTFE combines with the base body material (PE) to guarantee extensive resistance to chemicals
• Through temperature stabilization of the PE it is possible to use the elements at a permanent temperature of 100° C with transient peaks of up to 110° C
• The elements are marked with a C
• All other properties are the same as for the HSL elements

All elements are available in addition in a non-charging version CA, and the antistatic elements also come with a certificate.

Benefits

• Very low clean gas values < 0.1 mg/m³ (depending on the dust) even at high temperatures result in a high rate of product recovery and protect man, machine and the environment from dust
• A very long service life, also where abrasive dusts are involved, reduces the costs for servicing and spare parts
• Constant operating conditions (pressure and suction ratios) ensure stable processes with less control effort

Specifics

The materials used and the special geometry combine to lend the Herding^® sinter-plate filter unique properties, e.g. the elements can be washed and recycled and the base body can be recoated - dependent on the dust. In-house production of the filter medium and plant enables optimum coordination of the deposition of product with the particular process.
