Quick Open series multi-bag filter housings feature a self-balancing V-clamp locking mechanism, a break-through from conventional designs. Its single-handed, user-friendly operation makes this feature an ideal choice for applications with high flow rates requiring frequent element change-outs. Minimal downtime reduces operating costs and smoothen batch processes.
Efficiency is highly improved by a fully-interlocked pressure release which ensures safety in all conditions. With its rugged, corrosion-free V-clamp and proprietary screw-drive mechanism, the housing provides users with years of service.
Filter-bag's material and precision can be choosed:
PP(1-200um, 70°C max),
PE(1-200um, 120°C max),
Nylon(25-800um, 150°C max)
Stainless steel Multi bag filter machine technical data: Filter-Bag No. & size: 1#(180mmD*410mmL), 2#(180mmD*810mmL), 3#(102mmD*210mmL), 4#(102mmD*380mmL)
The position of the multi bag filter inlet is lower than that of filter bags. Filter medium enters from the inlet, reaches the top part of the housing above filter bags, flows downward and goes through filter bags for filtration. After filtration, impurities are trapped in filter bags, and the clean filtrate flows out from the outlet.
Filter bags need to be replaced when the impurities on filter bags build up into filter cakes and the differential pressure reaches 0.14-0.17 MPa. When replacing filter bags, you must shut down the filter system for a period of time, open the pressure relief valve and filter cover, and reinstall the filter after replacing filter bags. Filter bags can be reused after cleaning, but need to be replaced when damaged to a certain extent. Filter bags can be reused after cleaning, but need to be replaced when being damaged to a certain extent.

1.BOLT FASTENING-MORE PRESSURE RESISTANT
THE MULTI-BAG FILTER ADOPTS QUICK-OPENING FLANGE RING BOLTS TO TIGHTEN,WHICH HAS HIGHER PRESSURE RESISTANCE, AND A BOOSTER SPRING MECHANISM IS ADDED. IT IS A SIMPLE AND EASY-TO-USE OPERATION AND FREQUENT FILTER BAG REPLACEMENT OCCASIONS, WHICH REDUCES THE DOWNTIME. TO THE SHORTEST, PROMOTE PRODUCTIVITY AND REDUCE THE LABOR INTENSITY OF WORKERS, IMPROVE WORK EFFICIENCY.
2.SPRING-BALANCE MECHANISM
THE UNIQUE SPRING BALANCE MECHANISM MAKES IT EASY AND LABOR-SAVING TO OPEN AND CLOSE THE UPPER COVER, AND THE COVER CAN STAY AT ANY POSITION OF 0-105°WHEN OPENING AND CLOSING. THE SPRING BALANCE SUPPORT STRUCTURE IS SIMPLE AND DURABLE, AND THE CLAMSHELL DESIGN HAS A SMALL FOOTPRINT, AND THE LIQUID WILL NOT OVERFLOW WHEN THE LID IS OPENED.
3.THE CORE OF THE BAG FILTER SYSTEM
THE COMPRESSION SPRING PRESSURE PIECE CAN FORM A 360° SEAL WITH THE FILTER BAG TO ENSURE THAT THE FILTER BAG IS SEALED ON A FLAT SURFACE WITHOUT SIDE LEAKAGE. THE FILTER BAG IS THICKENED TO CARRY THE FLOWER PLATE, WHICH CAN BEAR HIGHER PRESSURE, REDUCE PRESSURE LOSS, AND IMPROVE THE FILTERING EFFECT. CUSTOMER FLOW REQUIREMENTS SUPPORT 2-24 BAGS OF CUSTOMIZATION.
Spring locking device easy to change filter bag
Basket gasket ensures 100% no leakage
4.DIRECTION OF INLET AND OUTLET
ACCORDING TO THE CUSTOMER'S USE AND INSTALLATION CONDITIONS, THE DIRECTION OF THE INLET AND OUTLET CAN BE CUSTOMIZED, AND THE FLANGE DIAMETER OF DN25-DN250 CAN BE CUSTOMIZED
