Product parameter:
PP bag filteris a cost-effective, high-efficiency solid-liquid separation device, engineered with premium food-grade polypropylene (PP) as the core material.
Featuring an integrally molded seamless construction, it utilizes specialized PP filter bags (melt-blown/needle-punched/hot-rolled) as the filtration medium, removing suspended solids, particles, sediment and other contaminants via physical interception. Boasting superior chemical stability and hygienic performance compliant with FDA standards, it delivers stable filtration for corrosive fluids, hygienic-grade materials and general industrial liquids, solving fluid contamination issues and protecting downstream equipment for global industrial users.
Technical Features
Premium Corrosion Resistance: Full PP construction resists acids, alkalis and most organic solvents, with zero deformation/deterioration in long-term use; suitable for fluids with a wide pH range, operating stably at temperatures ≤60℃.
Leak-Proof Seamless Design: One-piece injection-molded shell eliminates welds and gaps, preventing liquid leakage and bypass; smooth inner wall avoids residue buildup, simplifying cleaning and maintenance.
Wide Precision & High Dirt-Holding Capacity: Filtration accuracy ranges 0.5μm–200μm for flexible selection; porous PP filter bags offer exceptional dirt-holding power, maintaining steady efficiency even for high-impurity fluids.
Low Pressure Drop & Optimized Flow: Top/side inlet design creates unobstructed fluid channels, reducing resistance and energy consumption; maintains low pressure differential under high-flow operation.
Quick Maintenance & Safe Operation: Tool-free quick-opening cover and handle-equipped filter bags enable fast replacement, cutting downtime; avoids direct operator-fluid contact for enhanced safety.
Customizable Specifications: Tailored options for size, flow rate, connection types (flange/thread) and filter bag quantity to match diverse production scales and installation spaces.
Core Advantages
Our PP bag filter outperforms traditional metal filters with unbeatable benefits for industrial operations. It delivers exceptional cost savings with low upfront investment and affordable, easy-to-replace filter bags, slashing total operating and maintenance costs. Its high-efficiency filtration thoroughly removes impurities, safeguarding pumps, valves, membranes and other precision equipment to reduce wear and replacement frequency.Crafted from non-toxic, additive-free pure PP, it meets strict hygiene standards for food, beverage and pharmaceutical industries, ensuring zero secondary contamination. Its harsh-environment adaptability supports stable operation in chemical, electroplating and other corrosive settings, while its lightweight, user-friendly design requires no professional technicians for installation or upkeep, lowering labor costs.
Application Fields
Water Treatment: Municipal water pre-filtration, industrial circulating water purification, wastewater treatment, RO system security filtration, groundwater decontamination.
Food & Beverage: Edible oil refining, juice clarification, syrup/dairy filtration, wine/beverage fine filtration, adhering to food safety regulations.
Chemical & Electroplating: Acid/alkali solution filtration, plating bath purification, catalyst recovery, coating pretreatment for corrosive fluid handling.
Pharmaceutical & Bioengineering: Purified water filtration, medical intermediate processing, solvent recovery, meeting pharma-grade purity and hygiene norms.
Paints, Inks & Fine Chemicals: Resin/pigment purification, ink impurity removal, cosmetic raw material filtration to boost product fineness and quality.
Frequently Asked Questions (FAQ)
Q: How to choose the right filtration accuracy?
A: Select based on impurity particle size and purification needs: 50μm–200μm for coarse sediment removal, 0.5μm–20μm for food/pharma fine filtration. Contact us with fluid details for a free tailored recommendation.
Q: When to replace the PP filter bag?
A: Replace when pressure differential hits 0.1–0.15MPa or flow drops noticeably. High-impurity fluids: 15–30 days; low-impurity fluids: 30–90 days.
Q: What are the operating limits?
A: Standard operating temperature ≤60℃, stable working pressure 0.1–1.0MPa. Avoid ultra-high pressure/temperature environments to protect PP material integrity.
Q: Which fluids are incompatible?
A: Not suitable for strong oxidants (concentrated nitric acid, chlorine disinfectants), high-viscosity fluids (asphalt, heavy grease) or fluids over 80℃.
Q: Do you offer custom solutions?
A: Yes, we provide full customization including size, flow, connections, bag count and special anti-corrosion treatments. Share your working conditions for an exclusive filtration design.
