Description
Industrial Dual Laminate PP FRP Nutsche Filter Manufacturer in Gujarat
Nikunj Fibre Glass is a leading manufacturer and supplier of PP FRP Nutsche Filters (Dual Laminate Polypropylene Lined Fiberglass Vacuum Filtration Units) based in Vapi, Gujarat. Specifically engineered for pharmaceutical crystallization, bulk drug cake isolation, and aggressive chemical solid-liquid batch filtration, our PP FRP Nutsche filters deliver unmatched chemical inertness, vacuum stability, and easy product discharge.
Combining an ultra-smooth, cGMP-compliant virgin Polypropylene inner liner with a rigid filament-wound FRP structural outer shell, our Nutsche filters operate under full vacuum (-760 mm Hg) without risk of chemical corrosion or batch contamination.
Key Features & Advantages
- Dual Laminate Protection: Seamless virgin PP liner prevents chemical contamination of pharmaceutical cakes, while the outer structural FRP provides high vacuum rigidity.
- Precision CNC Perforated Filter Plate: Machined virgin PP perforated support plate ensures uniform cake formation and maximum filtrate drainage.
- Quick-Opening Domed Cover: Flanged dished top cover with quick-acting swing eye-bolts allows rapid cake harvesting and filter cloth changes.
- Integrated Wash Spray Distribution: Top-mounted spray nozzles deliver uniform wash solvent distribution across the entire cake surface.
- Complete Vacuum & Pressure Capability: Engineered for full negative vacuum (-760 mm Hg) and positive nitrogen gas cake blow-through.

Frequently Asked Questions (FAQ)
Q1: What makes PP FRP Nutsche filters suitable for pharmaceutical API manufacturing?
The virgin Polypropylene contact liner is food-grade and non-toxic (FDA compliant), does not leach metallic ions into sensitive drug formulations, and has an ultra-smooth finish that prevents product sticking.
Q2: Can the filter bottom be dropped for cake removal?
Yes, we manufacture both fixed-bed Nutsche filters and detachable bottom models equipped with quick-opening swing bolts or manual screw jacks for rapid cake discharge.
