▍INOCO SGD-S Multi-Bag Filter
Easy to operate, with an optimized fluid dynamic design, ideal for high flow and complex, fluctuating processes.
Innotech multi-bag filters are suitable for operating conditions with flow rates ranging from 60 to 5000 M /H. For filters with fewer bags, a handwheel and standard bearing swivel arm are included for easy opening and operation. For filters with 12 or more bags, cylinder or hydraulic assistance is optional, requiring only one person for opening and closing. Auxiliary devices, including pressure relief valves and locating pins, are incorporated to effectively ensure safe equipment operation.

▍INOCO SGD INOCO SGD-01D Large Flow Filter Bag
INOCO 01D series high-flow filter bags are the new generation of liquid bag filters. A single filter bag provides a filtration area of approximately 0.9 square meters, which is 1.8 times that of a traditional standard No. 2 filter bag.
This increases the filtration capacity of a single unit by 1.8 times, marking a significant innovation in the field of liquid bag filtration. The 01D filter bags, when used with dedicated support nets, are compatible with the majority of No. 2 bag filters and multi-bag filter systems available on the market.
▍INOCO SGD-02D High Contaminant Holding Pleated Filter Bag
INOCO pleated filter bags utilize deep three-dimensional
filtration materials, made from 100% pure fibers that are
needle-punched to form a three-dimensional, highly
fluffy, deep-bed structure with a tortuous path for
filtration. The characteristics include a loose fiber
organization, which significantly increases the
contaminant holding capacity and effectively removes
both solid and soft particles. Larger particles are trapped
on the fiber surface, while finer particles are captured
within the deeper layers of the filter media, thereby
achieving high filtration efficiency. The application of
instant sintering technology and calendering treatment
prevents fibers from being lost during filtration when
impacted by high-speed liquids, ensuring no fiber
shedding occurs to contaminate the filtrate.
The filtration accuracy grades:0.5、1、5、10、25、
50、75、100、200……
Filter Bag Materials: Polypropylene, Polyester, Nylon,
PTFE (Polytetrafluoroethylene)
Bag Ring Options: Polypropylene ring, Polyester ring,
Steel ring
