KAF Bernoulli

Product catalog summary

Applications
The KAF® Bernoulli® filter is a self-cleaning filter designed for removing particulate contaminants from polluted waters and process fluids. It operates at a minimum pressure of 0.3 bar with a low pressure loss of 0.09, suitable for high flow rates. It supports filtration stages from 160 microns to 10 mm and can be installed in any position.

Approvals
The filter holds various certifications including 3.1 Certificate, DGRL/TÜV, GL, LS, DNV, ABS, TR TF/TR CU Certificates (EAC), ASME U-Stamp, and Lloyd’s Register Type Approval Certificate No. 16/20086, conforming to the 2014/68/EU directive.

Technical Data
The filter is available in standard and special versions with filtration degrees ranging from 0.2 to 10 mm. It is constructed from materials such as plastic, stainless steel, cast iron, and GRP/FRP. It includes a differential pressure switch and can be controlled via a multi-function unit, requiring a compressed air supply of 6 bar.

Functional Description
The filter uses a flushing disk to increase speed and create a pressure drop, evacuating contaminants. The flushing process is triggered by differential pressure or time intervals, ensuring continuous filtrate flow with minimal pressure drop.

Operating Instructions
The filter must be installed stress-free in pipes, ensuring the medium flows in the specified direction. Compatibility between the medium and filter materials is the operator's responsibility. It is designed for quasi-static operation with a maximum differential pressure of 2 bar.

Filter Dimensioning
A dimensioning chart is provided to select the appropriate filter size based on flow rate and pressure loss. For example, at 500 m3/h, a DN 250 or DN 300 is recommended for a 200 µm filtration degree.

Product Range
The product range includes various filters such as the KAF® Self-cleaning Bernoulli®-filter, KRF Backflush-filter, SCF Scraper filter, and others, along with accessories like filter bags and strainers.

Certification
The filter is certified by Lloyd’s Register for use in ship and offshore installations, with ratings for different types and materials, including spheroidal iron casting and stainless steel.

Introduction
This document is a Type Approval Certificate issued by Lloyd's Register EMEA for Krone Filter Solutions GmbH, covering single, duplex, and automatic filter types KSF, KMF, KDF-K, KDF-V, KAF, and KRF. The certificate confirms compliance with Lloyd's Register's Type Approval System Procedure TA14.

Material Specifications
The document outlines temperature ranges and suitable fluids for various materials: Spheroidal cast iron: -10 to +300°C for MDO, oil, water, seawater; Austenitic stainless steel: -196 to +300°C for MDO, oil, nitrogen; Duplex stainless steel: -40 to +250°C for seawater; Carbon steel: -40 to +100°C for MDO, oil, water, seawater. Pressure reductions at elevated temperatures must be considered.

Media Compatibility
Different filter types are compatible with various media: KAF, KRF: water, seawater; KSF, KMF, KDF-K, KDF-V: MDO, oil, nitrogen, water, seawater.

Conditions and Limitations
Manufacturer's installation instructions must be followed. Not suitable for applications with significant shock or vibration loads. Type Approval does not replace normal inspection and survey procedures. Re-approval is required if standards are amended during the certificate's validity.

Approval Documentation
The document lists various data sheets and parts lists reviewed for compliance, including hydrostatic burst pressure tests and function tests of self-cleaning automatic filters.

Validity and Contact Information
Certificate No.: 16/20086; Issue Date: 09 September 2016; Expiry Date: 08 September 2021; Contact: Torsten Schröder, Senior Specialist, Engineering Systems, Lloyd’s Register EMEA, Hamburg Technical Support Office.

Conclusion
The Type Approval certifies compliance with design criteria for specified uses but does not imply approval for other uses or products not conforming to the representative sample. Lloyd’s Register reserves the right to cancel or withdraw the certificate as per their procedures.

KAF® Bernoulli® Self-Cleaning Automatic Filter PN 2-5 - 25 DN 40-1000 • No contact cleaning EN /ANSI/JIS/GOST • No process interruption Design Appraisal Certificate no. HPC1461050/34963-16/TS Type Approval Certificate no. 16/20086 The self-cleaning automatic KAF® Bernoulli® filter is a versatile self-cleaning, virtually maintenance-free filter for removal of particulate contaminants from highly polluted waters as well as process fluids e.g. from natural water sources (sea water, river water) and heating or cooling circuits and processes. It operates at a working pressure as low as 0.3 bar and is characterized by extremely low pressure loss of 0.09, for example, at a high flow rate, simple, robust design, with high performance, low weight, and space saving. • From a working pressure of 0.3 bar • The filter can be integrated in the pipe system in any installation position • Filtration stage > 160 microns (100 |j possible) - 10 mm Approvals 3.1.

Brief description A specially shaped ﬂushing disk gives rise to an increase in speed between the disk and strainer in the ﬂushing process. The resulting local pressure drop causes internal evacuation of the contaminant particles from the strainer insert. Solid components are ﬂushed out via the simultaneously opened ﬂush valve. The ﬁlter is equipped with a differential pressure monitoring system that automatically triggers the ﬂushing process before any blockages in the ﬁlter strainer cause signiﬁcant ﬂow reductions. The ﬂushing process can also take place after a predetermined time. • Filtrate...
