bag filters
bag filters
The bag filter housing is specially designed for industrial bag filter applications, taking into account both high-efficiency filtration and easy maintenance. The housing is made of 316L sanitary stainless steel with a mirror-polished surface, which can operate stably and long-term in high-flow liquids and corrosive media. Whether it is a food-grade bag filter or a high-pressure bag filter for chemical use, LiandaFiltration can provide a reliable solution.

Product Features and Benefits
High-efficiency microfiltration
Using high-quality filter bags, it can accurately intercept suspended particles and colloidal substances, with clear water and a stable removal rate of 99.5%.
Quick replacement of filter bags
With quick-open clamps, filter bags can be replaced without tools, and a single person can complete it within 1 minute, significantly reducing downtime.
Modular expansion
Optional multi-bag parallel design to meet the needs of large-flow bag dust collectors; support online module replacement to ensure production continuity.
Corrosion-resistant and pressure-resistant 316L stainless steel combined with precision welding technology, resistant to a variety of acid and alkali media, suitable for medium and high pressure conditions, and service life extended by 50%.
Meet hygiene standards
All parts in contact with liquids are mirror polished (Ra ≤ 0.4 μm) to meet food and pharmaceutical grade cleanliness requirements, such as FDA and 3-A.
Product application industry
Food and beverage: pre-filtration and clarification of fruit juice, beer, dairy products, edible oil, to ensure taste and hygiene safety.
Chemical coating: filtration of high viscosity liquid such as resin, paint, ink, etc., to prevent solid impurities from clogging downstream equipment.
Pharmaceutical and biological: aseptic filtration of aqueous solution, injection solution, etc. to ensure the purity of drugs.
Petrochemical industry: on-line filtration of lubricating oil, hydraulic oil and engine oil to extend the life of equipment.
Electronic industry: ultra-pure water, cleaning solution filtration, preventing ion pollution and microdust from causing yield reduction.
FAQ
When the inlet-outlet pressure difference (ΔP) exceeds the recommended value of 0.3 bar, or the water flow rate drops significantly, the filter bag can be replaced; it can also be replaced regularly every 3-6 months according to the production cycle.
Support customized filter bag materials (polypropylene, polyester, PTFE, etc.), interface forms and volumes to meet high temperature, high pressure or strong acid and alkali environments。
Some chemical-resistant filter bags (such as PTFE) can be reused after multiple chemical cleanings, while traditional PP/PE filter bags are recommended to be replaced once.
