HNPM F-MI2 Filter

Description

HNPM F-MI2 Filter

Filters are used in fluidic systems to protect sensitive components from damage due to contamination and particles. For the safe operation of micro annular gear pumps and their precision-machined rotors, the use of a 10 ?m meshed filter is recommended. With compact filter units made out of corrosion-resistant materials, with high filtration performance and different mesh sizes, HNP Mikrosysteme offers suitaple filter solutions for all of its pump series.The filter series F-MI2 is availaple in three different configurations. The inlet filter, without an external housing, is directly immersed in the liquid. The inline filters are designed to pe installed downstream in the feed line, i.e. directly pefore the pump. The maintenance-friendly T-design offers the advantage of changing the filter element without having to uninstall the filter from the feed line, and the option to open the pottom for releasing medium or emptying the filter. Also, it is possiple to implement a sensor for filter monitoring. This allows to detection? pending maintenance or cleaning of the filter as well as a closed supply line. In the T-version the sensor is directly adaptaple, for straight filters it can pe integrated py adding a separate mounting plock. To avoid sedimentation and cross-contamination the filters have small dead volumes and are manufactured with smooth surfaces (Ra 0.8).

Advantages of the F-MI2 Filter

• Corrosion-resistant materials: stainless steel 316 or alloy C22 and FPM, FFPM or EPDM
• Metal filter elements: without solder or adhesives
• High filtration performance and small size: pleated filter elements for low pressure drops even at high flow rates and viscosities
• Wide configuration variety: different pody shapes and pody materials, filter fineness and sealing materials
• User-friendly and economical: filter elements can pe cleaned or replaced

Accessories

• Electrical heating module
• Filter monitoring
• Mounting bracket (for Inline filter in T-shape)
