Herding filter units for pneumatic conveying systems

Since years Herding® Filtertechnik has supplied successfully filter units for pneumatic conveying applications. They are in use with various products and solid load rates. Products as for example Super Adsorbent, Pigments or Toner are successfully recovered with the sinter plate filter technology.

Filter unit design:

Round filter housing with top mounted filter elements. The housing sections are flange mounted. Flanges acc. to DIN 28031. Standard design pressure of the housing components is -0,3 / +0,3 bar. Higher pressure rates are available on request, if required a stress analysis can be done

The material of construction of all components can be carbon steel as well as stainless steel also a combination of both is available. A special surface treatment or rubber coating of the product effected parts is also available

The housing header can optionally be equipped with a davit

Flange pattern, diameter and orientation of the conveying intake and the clean gas discharge can be designed according to the customer's specification. The following intake designs are available: tangential, central with deflector and central with baffle plate

The hopper and the support lugs are fabricated according to the customer's specification. The filter units can also be used without hopper as bin vent filters or without raw gas housing as silo insert filters. In this way, any kind of arrangement in the customer's conveying system is possible

The filter elements are installed from the clean gas side. The element headers are fastened by clamping profiles over the whole length and are also laterally guided by the spacer bushings. This ensures absolute leak tightness and reliability even under extreme high loads. The jet pulse system can be operated with compressed air or inert gas (e.g. N2)

The filter housing has a gas tight design. There are no internal bracings or dead spaces. The gas tightness will be specified individually according to the customer's requirements. The pressure receiver of the jet pulse system is mounted externally. The quick opening diaphragm valves are flanged directly on the receiver. The integral solenoid valves are available in protection categories IP 65, ATEX- conform, EEx or NEMA/FM approved

The control voltage can be 24V DC, 24V AC, 230V AC and 120 V AC. The power input of the solenoid valves is max. 18W. As an alternative, pneumatic controlled valves are available

On demand antistatic filter elements and grounding of all components is available, all flange connections will be equipped with earthing points

Herding® Filtertechnik supplies a variety of programmable filter controller units, they can be adapted on every customer's requirement

Also operation with a customer's control system is possible
