Our pulse filters are automatic filters comprised of a cylindrical metal element (pulse tube) covered with a specific type of fabric filter cloth, depending on the application. The pulse filter elements are either mounted on stainless-steel septum plates and clamped between the filter housing vessel and the cover or hung from manifolds in larger filters.
Pulse filters usually have a low micron rating, depending on the type of filter cloth used, making the initial cake formation (bridging) easier. The use of filter aids to form a precoat layer can often be avoided altogether, resulting in lower product losses and decreased operational costs. Both dry and wet cake discharge is possible using back-pulsing with air or nitrogen to clean the filter elements and cloth.
Smaller models are also available for use as self-cleaning filters, heel filters, polish filters or as an alternative to bag filters. Instead of removing and replacing filter bags, pulse filters can be cleaned using a pulse of air or nitrogen, depending on the type of application. Back-pulsing is a safe procedure, avoiding toxic liquids or other harmful process fluids and reducing the number of times that the filter housing needs to be opened. This creates a safer environment for operators and reduces the additional consumable cost and time needed to change filter bags.
We provide a wide range of pulse filters for every application, including:
- Edible oil
- Sugar solutions
- Oleochemicals
- Gelatine
- Cocoa
- Plating industry
- Water treatment

Tailored filtration solutions to meet your needs
Selecting the right pulse filters for your application will depend on many factors like the flow rate, continuous or batch processing, the type and amount of solid load, the nature of the liquid, the temperature and the liquid viscosity.
Our team of process experts recommend solutions to maximise the effectiveness of your filtration process, enabling you to hit production and quality targets with a low total cost of ownership
