Automatic, blade & scraper filters

Filtration Group (FGI), previously known as Mahle Industrial, are based in Germany and stand as a leading provider of innovative filtration solutions tailored for various industries. Among their extensive product lineup, automatic filters play a pivotal role in ensuring the cleanliness and efficiency of liquids in numerous applications.

Understanding automatic filters

Automatic filters — also known as blade filters or scraper filters — are designed to continuously remove impurities from liquids without the need for manual intervention. This self-cleaning capability is crucial for industries where maintaining the quality of fluids is essential for operational efficiency. Filtration Group’s automatic filters are engineered for durability and reliability, making them ideal for demanding environments.

Types of automatic filters

FGI offers several types of automatic filter, each suited for specific applications.

1. Backwash filters

Functionality: these filters use a self-cleaning mechanism where filtered particles are removed by reversing the flow of liquid through the filter element. The process is triggered either by the pressure differential across the filter, or by a timed sequence.

• AF122G — operates on internal system pressure for cleaning.
• AF132G — utilises external pressure for the backwashing process.
• AF172G — allows backwashing without interrupting the filtration flow, ideal for critical operations.

2. Edge filters

Functionality: designed for filtration and homogenisation of both low and high-viscosity liquids, edge filters are versatile and effective.

• AF42 — a compact inline filter suitable for various applications.
• AF71 and AF72 series — specialised models addressing specific filtering needs.

3. Basket filters

Functionality: primarily used to protect pipelines and equipment by filtering out larger particles. Simple yet effective, and a cost-efficient solution.

• Simplex filters (e.g. EG2, EG3) — designed for single filtration lines.
• Duplex filters (e.g. UG54, UG87) — allow continuous operation by switching between two filters.

Complete units

The complete units from Filtration Group are designed to be user-friendly and efficient, and typically include:

• Filter housing — the robust casing that houses the filter element, designed to withstand high pressure and corrosive environments.
• Filter element — the core component that captures impurities. Depending on the model these can be made from various materials, including stainless steel, for durability and effectiveness.
• Control system — many automatic filters come with integrated control systems that monitor pressure differentials and automate the backwashing process, minimising downtime.
• Connections and fittings — standardised connections make installation straightforward, allowing quick integration into existing systems.

Replacement parts

To maintain optimal performance, replacement parts are essential. Filtration Group provides a range of components to keep filters operating efficiently over time:

• Filter elements — over time elements can become clogged or worn. A variety of compatible elements means worn components are easily replaced.
• Differential pressure switches — crucial for monitoring filter condition. If the pressure differential exceeds a threshold, it signals the need for backwashing or element replacement.
• Seals and gaskets — maintaining a proper seal is vital. Replacement seals and gaskets prevent leaks and keep the filter operating under optimal conditions.
• Control systems — if a control system malfunctions, replacements restore functionality. These systems are essential for automating cleaning and monitoring performance.
• Miscellaneous accessories — valves, connectors and other fittings that may require replacement over time.

Advantages of Filtration Group’s automatic filters

• Continuous operation — the self-cleaning feature allows 24/7 operation without manual cleaning, reducing labour costs and downtime.
• Enhanced fluid quality — efficient filtration significantly improves the quality of processed liquids, leading to better product quality and reduced wear on machinery.
• Customisable solutions — a range of models and configurations lets businesses select the best fit for their specific needs.
• Long-term cost savings — although the initial investment may be higher, reduced maintenance and filter longevity lead to savings over time.

Applications
