Our bag filtration systems are widely used for the reduction of sediment from industrial and food applications due to their high flow rate capability, easy maintenance, and rugged design.

Filter Bags and Socks – Particulate Removal

Siga Filtration manufacture and supply a varied range of filter bags for general particulate removal and high-efficiency removal of particulates.

For high flow filtration rate applications, Siga Filtration can offer multi-bag filter housings that can handle flow rates of up to 400 m3/h. All standard filter bags are supplied with integrated handles for easy removal from filter housings. Filter bags are available with removal ratings from 0.5 – 1800 µm.

Polypropylene Socks, Polyester and Nylon Felt Filter Bags

Siga Filtration can supply filter socks in Polypropylene felt, Polyester felt, and Nylon mesh filter bags. Polypropylene felt has wide chemical compatibility and is suitable for most industrial, water and chemical applications up to an operating temperature of 80°C.

Fuel Filtration Socks – Gasoline and Diesel

Polyester felt fuel filter socks have a high-temperature resistance (up to 120°C with SS or Polyester ring). These filter bags also provide excellent resistance against hydrocarbons and are a material of choice for the filtration and polishing of gasoline, diesel, biodiesel, and other fuels.

Both Polyester and Polypropylene felt filter bags provide clarification of particles. These filter bags also provide removal of gelatinous or deformable particles due to the depth of the filter medium.

Nylon monofilament mesh filter bags remove particles by sieving and are used for the classification of particles.

Vodka, Whisky, Gin, Kombucha Beverage Basket Filters

Alcoholic beverages such as vodka, whisky, gin, kombucha and other beverages require high efficiency particulate removal filters. Read more about the basket filtration solutions we manufacture and supply.

Bag Size 1 – 7” x 16” approx. with a moulded plastic collar, stainless steel ring, drawstring or no collar
Bag Size 2 – 7” x 32” approx. with a moulded plastic collar, stainless steel ring, drawstring or no collar
Bag Size 3 – 4” x 8.8” approx. with a moulded plastic collar, stainless steel ring, drawstring or no collar
Bag size 4 – 4” x 15” approx. with a moulded plastic collar, stainless steel ring, drawstring or no collar
Custom bespoke size – These filter bags can be manufactured to customer specifications and sizes.

Filter bag high flow rates

Our filter bags provide a high flow rate capability combined with excellent dirt holding capacity. Flow rates depend on many factors like application, particulate concentration, micron rating, and viscosity. A general guide to flow rates provided below for water with 10 micron felt type filter bag.

Size 1 bags – 20 m3/h
Size 2 bags – 40 m3/h
Size 3 bags – 6 m3/h
Size 4 bags – 12 m3/h

Food grade filter bags

Our BREWBag filter bags are constructed from food-grade materials and provide an excellent particulate reduction solution for various production stages in the food & beverage industry. These filter bags are available in micron ratings from 0.5 – 1800 µm.

Custom bespoke filter manufacturer UK

In addition to standard sizes, we can supply filter bags in customer specified lengths and diameters.

Extended life and high-efficiency filter bags
Extended life filter bags feature a thicker media for increased particle retention and filter life. These are ideal for applications where longer filter life is required to reduce maintenance demand. Our high-efficiency filter socks can provide greater than 99% removal of particulates in applications that require an extremely low particulate count.

Filter bag micron ratings

Polypropylene & Polyester felt filter socks – 0.5, 1, 5, 10, 25, 50, 100, 200 µm
Nylon monofilament mesh filter socks – 1, 5, 10, 25, 50, 75, 100, 125, 150, 200, 250, 300, 400, 500, 600, 800, 1000, 1200, 1800 µm

Filter bag chemical compatibility

Our standard filter bags provide broad chemical compatibility in industrial and chemical applications.
Polypropylene felt bags – Acids, alkalis, organic solvents, alcohols, oxidisers
Polyester felt bags – Hydrocarbons, alcohols, acids, solvents
Nylon monofilament mesh bags – Solvents
* Chemical resistance depends on operating temperature, process fluid, and application. The material should be soak tested prior to use.
